100-626: Sultan Kudarat , officially the Province of Sultan Kudarat ( Hiligaynon : Kapuoran sang Sultan Kudarat ; Maguindanaon : Dairat nu Sultan Kudarat , Jawi : دايرت نو سولتان كودرت; Cebuano : Lalawigan sa Sultan Kudarat ; Ilocano : Probinsia ti Sultan Kudarat ; Filipino : Lalawigan ng Sultan Kudarat ), is a province in the Philippines located in the Soccsksargen region in Mindanao . Its capital
200-495: A large lake . Earthquakes , volcanic eruptions and underwater explosions (including detonations, landslides , glacier calvings , meteorite impacts and other disturbances) above or below water all have the potential to generate a tsunami. Unlike normal ocean waves, which are generated by wind , or tides , which are in turn generated by the gravitational pull of the Moon and the Sun ,
300-430: A wave shoaling process described below. A tsunami can occur in any tidal state and even at low tide can still inundate coastal areas. On April 1, 1946, the 8.6 M w Aleutian Islands earthquake occurred with a maximum Mercalli intensity of VI ( Strong ). It generated a tsunami which inundated Hilo on the island of Hawaii with a 14-metre high (46 ft) surge. Between 165 and 173 were killed. The area where
400-522: A Western Bisayan language, while Capiznon is a Central Bisayan language closely related to Hiligaynon. Consonants [d] and [ɾ] were once allophones but cannot interchange as in other Philippine languages: patawaron ('to forgive') [from patawad , 'forgiveness'] but not patawadon , and tagadiín ('from where') [from diín , 'where'] but not tagariín . There are four main vowels: /a/ , /i ~ ɛ/ , /o ~ ʊ/ , and /u/ . [i] and [ɛ] (both spelled i ) are allophones , with [i] in
500-535: A dog. When an adjective modifies a noun, the linker nga links the two. Example: Ido nga itom 'black dog' Sometimes, if the linker is preceded by a word that ends in a vowel, glottal stop or the letter N, it becomes acceptable to contract it into -ng , as in Filipino. This is often used to make the words sound more poetic or to reduce the number of syllables. Sometimes the meaning may change as in maayo nga aga , '(the) good morning', and maayong aga ,
600-427: A few minutes at a time. The Tauredunum event was a large tsunami on Lake Geneva in 563 CE, caused by sedimentary deposits destabilised by a landslide. In the 1950s, it was discovered that tsunamis larger than had previously been believed possible can be caused by giant submarine landslides . These large volumes of rapidly displaced water transfer energy at a faster rate than the water can absorb. Their existence
700-432: A huge wave. As the tsunami approaches the coast and the waters become shallow, wave shoaling compresses the wave and its speed decreases below 80 kilometres per hour (50 mph). Its wavelength diminishes to less than 20 kilometres (12 mi) and its amplitude grows enormously—in accord with Green's law . Since the wave still has the same very long period , the tsunami may take minutes to reach full height. Except for
800-537: A large problem of awareness and preparedness, as exemplified by the eruption and collapse of Anak Krakatoa in 2018 , which killed 426 and injured thousands when no warning was available. It is still regarded that lateral landslides and ocean-entering pyroclastic currents are most likely to generate the largest and most hazardous waves from volcanism; however, field investigation of the Tongan event , as well as developments in numerical modelling methods, currently aim to expand
900-528: A massive landslide from Monte Toc entered the reservoir behind the Vajont Dam in Italy. The resulting wave surged over the 262-metre (860 ft)-high dam by 250 metres (820 ft) and destroyed several towns. Around 2,000 people died. Scientists named these waves megatsunamis . Some geologists claim that large landslides from volcanic islands, e.g. Cumbre Vieja on La Palma ( Cumbre Vieja tsunami hazard ) in
1000-570: A reference sea level. A large tsunami may feature multiple waves arriving over a period of hours, with significant time between the wave crests. The first wave to reach the shore may not have the highest run-up. About 80% of tsunamis occur in the Pacific Ocean, but they are possible wherever there are large bodies of water, including lakes. However, tsunami interactions with shorelines and the seafloor topography are extremely complex, which leaves some countries more vulnerable than others. For example,
1100-462: A ridge and a trough. In the case of a propagating wave like a tsunami, either may be the first to arrive. If the first part to arrive at the shore is the ridge, a massive breaking wave or sudden flooding will be the first effect noticed on land. However, if the first part to arrive is a trough, a drawback will occur as the shoreline recedes dramatically, exposing normally submerged areas. The drawback can exceed hundreds of metres, and people unaware of

#17330858277441200-754: A secondary lingua franca in the province. Aside from the Hiligaynons, who settled in Sultan Kudarat around the 17th to 18th centuries along with the Karay-as, whereas their fellow new settlers from Visayas continued until the Philippine independence, other ethnic groups in the province include the Maguindanaons (who constitute the majority of the provincial Muslim population), as well as the Manobos , Tedurays and Blaans ,
1300-467: A significant tsunami, such as the 1977 Sumba and 1933 Sanriku events. Tsunamis have a small wave height offshore, and a very long wavelength (often hundreds of kilometres long, whereas normal ocean waves have a wavelength of only 30 or 40 metres), which is why they generally pass unnoticed at sea, forming only a slight swell usually about 300 millimetres (12 in) above the normal sea surface. They grow in height when they reach shallower water, in
1400-628: A transoceanic tsunami has not occurred within recorded history. Susceptible locations are believed to be the Big Island of Hawaii , Fogo in the Cape Verde Islands , La Reunion in the Indian Ocean , and Cumbre Vieja on the island of La Palma in the Canary Islands ; along with other volcanic ocean islands. This is because large masses of relatively unconsolidated volcanic material occurs on
1500-445: A tsunami can be calculated by obtaining the square root of the depth of the water in metres multiplied by the acceleration due to gravity (approximated to 10 m/s ). For example, if the Pacific Ocean is considered to have a depth of 5000 metres, the velocity of a tsunami would be √ 5000 × 10 = √ 50000 ≈ 224 metres per second (730 ft/s), which equates to a speed of about 806 kilometres per hour (501 mph). This
1600-434: A tsunami can be generated when thrust faults associated with convergent or destructive plate boundaries move abruptly, resulting in water displacement, owing to the vertical component of movement involved. Movement on normal (extensional) faults can also cause displacement of the seabed, but only the largest of such events (typically related to flexure in the outer trench swell ) cause enough displacement to give rise to
1700-444: A tsunami is generated by the displacement of water from a large event. Tsunami waves do not resemble normal undersea currents or sea waves because their wavelength is far longer. Rather than appearing as a breaking wave , a tsunami may instead initially resemble a rapidly rising tide . For this reason, it is often referred to as a tidal wave , although this usage is not favoured by the scientific community because it might give
1800-473: A tsunami, which is that of an extraordinarily high tidal bore . Tsunamis and tides both produce waves of water that move inland, but in the case of a tsunami, the inland movement of water may be much greater, giving the impression of an incredibly high and forceful tide. In recent years, the term "tidal wave" has fallen out of favour, especially in the scientific community, because the causes of tsunamis have nothing to do with those of tides , which are produced by
1900-605: Is Isulan while the commercial center and largest city is Tacurong . On February 23, 1995, Sultan Kudarat transferred from the Autonomous Region in Muslim Mindanao (now Bangsamoro Autonomous Region ) to Soccsksargen. The name Sultan Kudarat given to the province was derived from the Maguindanaon Muslim ruler, Sultan Muhammad Dipatuan Kudarat who began to assert his leadership in the year 1619 and reigned in
2000-596: Is also accustomed to tsunamis, with earthquakes of varying magnitudes regularly occurring off the coast of the island. Tsunamis are an often underestimated hazard in the Mediterranean Sea and parts of Europe. Of historical and current (with regard to risk assumptions) importance are the 1755 Lisbon earthquake and tsunami (which was caused by the Azores–Gibraltar transform fault ), the 1783 Calabrian earthquakes , each causing several tens of thousands of deaths and
2100-557: Is also used to refer to the phenomenon because the waves most often are generated by seismic activity such as earthquakes. Prior to the rise of the use of the term tsunami in English, scientists generally encouraged the use of the term seismic sea wave rather than tidal wave . However, like tidal wave , seismic sea wave is not a completely accurate term, as forces other than earthquakes—including underwater landslides , volcanic eruptions, underwater explosions, land or ice slumping into

#17330858277442200-552: Is beautiful.' 'Sara is beautiful' (English) There is no direct translation for the English copula to be in Hiligaynon. However, the prefixes mangin- and nangin- may be used to mean will be and became, respectively. Example: Manamì mangín manggaránon. 'It is nice to become rich.' The Spanish copula estar ('to be') has also become a part of the Hiligaynon lexicon. Its meaning and pronunciation have changed compared to its Spanish meaning, however. In Hiligaynon it
2300-562: Is composed of three sub-variants: Northern, Central and Southern Negrense Hiligaynon), Guimaras Hiligaynon, and Mindanao Hiligaynon (which incorporated some Cebuano and other languages due to the mass influx of migrants from Cebu , Bohol , Siquijor and Cebuano-speaking parts of Mindanao reside in the Soccsksargen area). Some native speakers also consider Kinaray-a (also known as Hiniraya or Antiqueño) and Capiznon dialects of Hiligaynon. However, linguists have classified Kinaray-a as
2400-491: Is designed to help accurately forecast the passage of tsunamis across oceans as well as how tsunami waves interact with shorelines. The term "tsunami" is a borrowing from the Japanese tsunami 津波 , meaning "harbour wave." For the plural, one can either follow ordinary English practice and add an s , or use an invariable plural as in the Japanese. Some English speakers alter the word's initial / ts / to an / s / by dropping
2500-719: Is mainly concentrated in the regions of Western Visayas ( Iloilo , Capiz , and Guimaras ), Negros Island Region ( Negros Occidental ), and Soccsksargen ( South Cotabato including General Santos , Sultan Kudarat , and North Cotabato ). It is spoken in other neighboring provinces , such as Antique and Aklan in Western Visayas, Negros Oriental in Negros Island Region, Masbate in Bicol Region , and southern parts of Mindoro , Romblon and Palawan in Mimaropa . It
2600-580: Is more commonly used, which has rarely or never been used by other dialects of the language. Another example, amó iní , ('this is it') in Standard Hiligaynon can be simplified in Urban Hiligaynon and become 'mó'ní . Some of the other widely recognized dialects of the language, aside from Standard Hiligaynon and Urban Hiligaynon, are Bacolodnon Hiligaynon ( Metro Bacolod dialect), Negrense Hiligaynon (provincial Negros Occidental dialect that
2700-517: Is no officially recognized standard orthography for the language and different writers may follow different conventions. It is common for the newer generation, however, to write the language based on the current orthographic rules of Filipino. A noticeable feature of the Spanish-influenced orthography absent in those writing following Filipino's orthography is the use of "c" and "qu" in representing /k/ (now replaced with "k" in all instances) and
2800-762: Is now Shakespear Regional Park at the tip of the Whangaparāoa Peninsula in the Auckland Region of New Zealand ; the attempt failed. There has been considerable speculation about the possibility of using nuclear weapons to cause tsunamis near an enemy coastline. Nuclear testing in the Pacific Proving Ground by the United States generated poor results. In Operation Crossroads in July 1946, two 20-kilotonne-of-TNT (84 TJ) bombs were detonated, one in
2900-590: Is predominantly agricultural. The leading crops produced in the province are rice, corn, coconuts, coffee, bananas, mangoes, durians and African palm. The province is self-sufficient in poultry, swine and root crops, and is one of the few producers of Irish potatoes in the Philippines. The southern Philippines Grain Complex in Tacurong is the largest grains-processing complex in the country. There are more than 200 rice mills in
3000-500: Is pronounced as istar and means 'to live (in)/location' (Compare with the Hiligaynon word puyô ). Example: Nagaistar ako sa tabuk suba. 'I live in tabuk suba'. Tabuk suba translates to 'other side of the river' and is also a barangay in Jaro, Iloilo. To indicate the existence of an object, the word may is used. Example: May EXIST idô dog (a)ko 1SG May idô (a)ko EXIST dog 1SG I have
3100-613: Is spoken as a second language by Kinaray-a speakers in Antique , Aklanon/Malaynon speakers in Aklan , Capiznon speakers in Capiz , Cebuano speakers in Negros Oriental , and spoken and understood by native speakers of Maguindanaon , Cebuano, Ilocano , Blaan , Tboli and other settler and indigenous languages in Soccsksargen in Mindanao .

3200-656: Is the subject and which is the object ; rather, the affix of the verb determines this, though the ang -marked noun is always the topic. In addition to this, there are two verbal deictics , karí , meaning 'to come to the speaker', and kadto , meaning 'to go yonder'. Hiligaynon lacks the marker of sentence inversion ay of Tagalog/Filipino or hay of Akeanon. Instead sentences in SV form (Filipino: Di karaniwang anyo ) are written without any marker or copula. Examples: Si Sara ay maganda (Tagalog) Si Sara matahum / Gwapa si Sara (Hiligaynon) = 'Sara
3300-426: Is the formula used for calculating the velocity of shallow-water waves. Even the deep ocean is shallow in this sense because a tsunami wave is so long (horizontally from crest to crest) by comparison. The reason for the Japanese name "harbour wave" is that sometimes a village's fishermen would sail out, and encounter no unusual waves while out at sea fishing, and come back to land to find their village devastated by
3400-404: Is used medially to indicate the glottal stop san-o 'when' gab-e 'evening; night'. It is also used in reduplicated words: adlaw-adlaw 'daily, every day', from adlaw 'day, sun'. This marking is not used in reduplicated words whose base is not also used independently, as in pispis 'bird'. Hyphens are also used in words with successive sounds of /g/ and /ŋ/ , to separate
3500-430: The 1883 eruption of Krakatoa , and the 2022 Hunga Tonga–Hunga Ha'apai eruption . Over 20% of all fatalities caused by volcanism during the past 250 years are estimated to have been caused by volcanogenic tsunamis. Debate has persisted over the origins and source mechanisms of these types of tsunamis, such as those generated by Krakatoa in 1883, and they remain lesser understood than their seismic relatives. This poses
3600-666: The 1908 Messina earthquake and tsunami. The tsunami claimed more than 123,000 lives in Sicily and Calabria and is among the deadliest natural disasters in modern Europe. The Storegga Slide in the Norwegian Sea and some examples of tsunamis affecting the British Isles refer to landslide and meteotsunamis , predominantly and less to earthquake-induced waves. As early as 426 BC the Greek historian Thucydides inquired in his book History of
3700-413: The Canary Islands , may be able to generate megatsunamis that can cross oceans, but this is disputed by many others. In general, landslides generate displacements mainly in the shallower parts of the coastline, and there is conjecture about the nature of large landslides that enter the water. This has been shown to subsequently affect water in enclosed bays and lakes, but a landslide large enough to cause
3800-684: The Hiligaynon people . It is the second-most widely spoken language in the Visayas and belongs to the Bisayan languages , and it is more distantly related to other Philippine languages . It also has one of the largest native language-speaking populations of the Philippines , despite it not being taught and studied formally in schools and universities until 2012. Hiligaynon is given the ISO 639-2 three-letter code hil , but has no ISO 639-1 two-letter code. Hiligaynon

Aside from Hiligaynon , the language is also referred to as Ilonggo , also spelled Ilongo , as it originated in Iloilo. Many speakers outside Iloilo argue, that this is an incorrect usage of the word Ilonggo . In precise usage, these people opine that Ilonggo should be used only in relation to
4100-606: The Sultanate of Maguindanao from 1625 to 1671. Through his leadership, Spanish forces were successfully repelled from encroaching the Cotabato region of south-central Mindanao. He is considered a national hero, and in his honor, the province was named after him. Sultan Kudarat was once part of the Sultanate of Maguindanao . It became one of the strongholds of the Maguindanao society as some royal families established their own Sultanate in

Again, this is an example of a case marker that has fallen largely into disuse, but is still occasionally used when speaking a more traditional form of Hiligaynon, using fewer Spanish loan words. The case markers do not determine which noun

In Sicily they are called marubbio and in Nagasaki Bay, they are called abiki . Some examples of destructive meteotsunamis include 31 March 1979 at Nagasaki and 15 June 2006 at Menorca, the latter causing damage in the tens of millions of euros. Meteotsunamis should not be confused with storm surges , which are local increases in sea level associated with
4600-472: The Pacific coasts of the United States and Mexico lie adjacent to each other, but the United States has recorded ten tsunamis in the region since 1788, while Mexico has recorded twenty-five since 1732. Similarly, Japan has had more than a hundred tsunamis in recorded history, while the neighbouring island of Taiwan has registered only two, in 1781 and 1867. All waves have a positive and negative peak; that is,
4700-577: The Peloponnesian War about the causes of tsunami, and was the first to argue that ocean earthquakes must be the cause. The oldest human record of a tsunami dates back to 479 BC , in the Greek colony of Potidaea , thought to be triggered by an earthquake. The tsunami may have saved the colony from an invasion by the Achaemenid Empire . The cause, in my opinion, of this phenomenon must be sought in
4800-451: The Spanish colonizers called Arayas , which may be a Spanish misconception of the Hiligaynon words Iraya or taga-Iraya , or the current and more popular version Karay-a ('highlanders' – people of Iraya / highlands ). Similar to many languages in the Philippines , very little research on dialectology has been done on Hiligaynon. Standard Hiligaynon, is the dialect that is used in

The core alphabet consists of 20 letters used for expressing consonants and vowels in Hiligaynon, each of which comes in an uppercase and lowercase variety. The apostrophe ⟨'⟩ and hyphen ⟨-⟩ also appear in Hiligaynon writing, and might be considered separate letters. The hyphen, in particular,

The bombs detonated about 6 km (3.7 mi; 3.2 nmi) from the nearest island, where the waves were no higher than 3 to 4 m (9.8 to 13.1 ft) when they reached the shoreline. Other underwater tests, mainly Operation Hardtack I /Wahoo in deep water and Operation Hardtack I/Umbrella in shallow water, confirmed

The vowels [ʊ] and [o] are also allophones, with [ʊ] always being used when it is the beginning of a syllable, and [o] always used when it ends a syllable. Hiligaynon is written using the Latin script . Until the second half of the 20th century, Hiligaynon was widely written largely following Spanish orthographic conventions. Nowadays there

The province has an irregular coastline of 132 kilometres (82 mi) in its three coastal towns, which face the Celebes Sea. These coastal areas are prone to tsunamis coming from the Celebes Sea. Approximately 2/3 of Lake Buluan 's area is covered by the province in the towns of Lutayan and President Quirino. There are 7 major rivers within

The average temperature is 35 °C (95 °F), with 38 °C (100 °F) as the average maximum normally occurring in March. The lowest recorded was 18 °C (64 °F) in the Kulaman area from December to early January. Sultan Kudarat comprises 11 municipalities and 1 city . Three of

Thus, the sea recedes in the drawback phase, with areas well below sea level exposed after three minutes. For the next six minutes, the wave trough builds into a ridge which may flood the coast, and destruction ensues. During
5500-455: The deep ocean has a much larger wavelength of up to 200 kilometres (120 mi). Such a wave travels at well over 800 kilometres per hour (500 mph), but owing to the enormous wavelength the wave oscillation at any given point takes 20 or 30 minutes to complete a cycle and has an amplitude of only about 1 metre (3.3 ft). This makes tsunamis difficult to detect over deep water, where ships are unable to feel their passage. The velocity of

Examples of tsunamis originating at locations away from convergent boundaries include Storegga about 8,000 years ago, Grand Banks in 1929, and Papua New Guinea in 1998 (Tappin, 2001). The Grand Banks and Papua New Guinea tsunamis came from earthquakes which destabilised sediments, causing them to flow into
5700-408: The earthquake. At the point where its shock has been the most violent the sea is driven back, and suddenly recoiling with redoubled force, causes the inundation. Without an earthquake I do not see how such an accident could happen. The Roman historian Ammianus Marcellinus ( Res Gestae 26.10.15–19) described the typical sequence of a tsunami, including an incipient earthquake, the sudden retreat of

Two major mountain ranges encompass the province; the Alip Mountain Range in Columbio and the Daguma Mountain Range within the towns of Bagumbayan, Isulan, and Esperanza. The three coastal towns on the province's western side (Lebak, Kalamansig, and Palimbang) are lined with mountain ranges that separate

The disagreement over the usage of Ilonggo to refer to the language extends to Philippine language specialists and native laypeople. Historical evidence from observations of early Spanish explorers in the Archipelago shows that the nomenclature used to refer to this language had its origin among
6000-449: The false impression of a causal relationship between tides and tsunamis. Tsunamis generally consist of a series of waves, with periods ranging from minutes to hours, arriving in a so-called " wave train ". Wave heights of tens of metres can be generated by large events. Although the impact of tsunamis is limited to coastal areas, their destructive power can be enormous, and they can affect entire ocean basins. The 2004 Indian Ocean tsunami
6100-406: The flanks and in some cases detachment planes are believed to be developing. However, there is growing controversy about how dangerous these slopes actually are. Other than by landslides or sector collapse , volcanoes may be able to generate waves by pyroclastic flow submergence, caldera collapse, or underwater explosions. Tsunamis have been triggered by a number of volcanic eruptions, including

#17330858277446200-491: The gravitational pull of the moon and sun rather than the displacement of water. Although the meanings of "tidal" include "resembling" or "having the form or character of" tides, use of the term tidal wave is discouraged by geologists and oceanographers. A 1969 episode of the TV crime show Hawaii Five-O entitled "Forty Feet High and It Kills!" used the terms "tsunami" and "tidal wave" interchangeably. The term seismic sea wave

The population of Sultan Kudarat in the 2020 census was 854,052 people, with a density of 160 inhabitants per square kilometre or 410 inhabitants per square mile. At the 2000 census, the province had a total population of 586,505 inhabitants, which grew to 747,087 in the 2010 census. About 113 ethnic groups were identified in the province in the 2000 Census. The Hiligaynons constitute

In addition, some English letters may be used in borrowed words. Hiligaynon has three types of case markers: absolutive , ergative , and oblique . These types in turn are divided into personal, that have to do with names of people, and impersonal, that deal with everything else, and further into singular and plural types, though

Storm surges and setup are also dangerous causes of coastal flooding in severe weather but their dynamics are completely unrelated to tsunami waves. They are unable to propagate beyond their sources, as waves do. The accidental Halifax Explosion in 1917 triggered an 18-metre (59 ft) high tsunami in

Other languages spoken in the province are Maguindanaon , Karay-a , Dulangan Manobo , Blaan , Teduray , Ilocano , and Cebuano . Filipino and English are also widely understood and used in education, business, and administration as the national official languages, the former serving as dominant language in local media and of everyday communication of speakers of different languages, making it
7100-408: The most number of hospitals in the province with 11, followed by Isulan with 5. As of 2010, the provincial road network spanned a total length of 3,749.5813 kilometres (2,329.8818 mi) of which 49.26% were barangay roads, 27.97% provincial roads, 13.51% municipal/city roads and 9.25% national roads. Bagumbayan had the longest road network at 516.789 kilometres (321.118 mi), while Lutayan had
7200-400: The mountainous areas of Isulan, Bagumbayan, Sen. Ninoy Aquino, Palimbang and Columbio. Non-metallic minerals which include sand, gravel and marbleized limestone are also found in the province. For the school year 2009–2010, the province has 475 schools (401 public and 74 private), 368 of which were elementary schools, 90 were secondary, and 17 were tertiary. Sultan Kudarat State University is
7300-407: The municipalities ( Kalamansig , Lebak , and Palimbang ) are coastal towns, while the rest of the province is located inland. The 11 municipalities and Tacurong City are further subdivided into 249 barangays . Tacurong City is the smallest unit in the province by land area, but is the most urbanized and is considered the province's commercial center. Other growth centers are Lebak and Isulan ,
7400-611: The nearest coastline, with the tsunami height defined as the rise of the water level above the normal tidal level at the time of occurrence of the tsunami. This scale, known as the Soloviev-Imamura tsunami intensity scale , is used in the global tsunami catalogues compiled by the NGDC/NOAA and the Novosibirsk Tsunami Laboratory as the main parameter for the size of the tsunami. This formula yields: In 2013, following
7500-405: The next six minutes, the wave changes from a ridge to a trough, and the flood waters recede in a second drawback. Victims and debris may be swept into the ocean. The process repeats with succeeding waves. As with earthquakes, several attempts have been made to set up scales of tsunami intensity or magnitude to allow comparison between different events. The first scales used routinely to measure
7600-847: The ocean and generate a tsunami. They dissipated before travelling transoceanic distances. The cause of the Storegga sediment failure is unknown. Possibilities include an overloading of the sediments, an earthquake or a release of gas hydrates (methane etc.). The 1960 Valdivia earthquake ( M w 9.5), 1964 Alaska earthquake ( M w 9.2), 2004 Indian Ocean earthquake ( M w 9.2), and 2011 Tōhoku earthquake ( M w 9.0) are recent examples of powerful megathrust earthquakes that generated tsunamis (known as teletsunamis ) that can cross entire oceans. Smaller ( M w 4.2) earthquakes in Japan can trigger tsunamis (called local and regional tsunamis) that can devastate stretches of coastline, but can do so in only
7700-437: The ocean, meteorite impacts, and the weather when the atmospheric pressure changes very rapidly—can generate such waves by displacing water. The use of the term tsunami for waves created by landslides entering bodies of water has become internationally widespread in both scientific and popular literature, although such waves are distinct in origin from large waves generated by earthquakes. This distinction sometimes leads to
7800-505: The only public tertiary school within the province, with its main campus at Tacurong City. Its other campuses are situated in Bagumbayan, Isulan, Kalamansig, Lutayan, Palimbang, and Senator Ninoy Aquino. In 2010, Sultan Kudarat had 27 hospitals (5 government-owned, 22 private and 1 mobile hospital), which are classified into 17 primary (6-25 beds capacity), 8 secondary (25-100 beds capacity) and 2 tertiary (over 100 beds capacity). Tacurong had
7900-577: The people of the coasts or people of the Ilawod (" los [naturales] de la playa ") in Iloilo, Panay, whom Spanish explorer Miguel de Loarca called Yligueynes (or the more popular term Hiligaynon , also referred to by the Karay-a people as Siná ). The term Hiligaynon came from the root word ilig ('to go downstream'), referring to a flowing river in Iloilo. In contrast, the Kinaray-a has been used by what
8000-484: The plural impersonal case markers are just the singular impersonal case markers + mga (a contracted spelling for /maŋa/ ), a particle used to denote plurality in Hiligaynon. (*)The articles sing and sing mga means the following noun is indefinite , while sang tells of a definite noun, like the use of a in English as opposed to the ; however, it is not as common in modern speech, being replaced by sang . It appears in conservative translations of
8100-478: The possibility of a meteorite causing a tsunami is debated. Tsunamis can be generated when the sea floor abruptly deforms and vertically displaces the overlying water. Tectonic earthquakes are a particular kind of earthquake that are associated with the Earth's crustal deformation; when these earthquakes occur beneath the sea, the water above the deformed area is displaced from its equilibrium position. More specifically,
8200-433: The potential energy. Difficulties in calculating the potential energy of the tsunami mean that this scale is rarely used. Abe introduced the tsunami magnitude scale M t {\displaystyle {\mathit {M}}_{t}} , calculated from, where h is the maximum tsunami-wave amplitude (in m) measured by a tide gauge at a distance R from the epicentre, a , b and D are constants used to make
8300-487: The province are: Festivals celebrated within the province include: Download coordinates as: Hiligaynon language Hiligaynon , also often referred to as Ilonggo or Binisayâ/Bisayâ nga Hiniligaynon/Inilonggo , is an Austronesian regional language spoken in the Philippines by about 9.1 million people, predominantly in Western Visayas , Negros Island Region , and Soccsksargen , most of whom belong to
8400-506: The province of Iloilo , primarily in the northern and eastern portions of the province. It has a more traditional and extensive vocabulary, whereas the Urban Hiligaynon dialect spoken in Metro Iloilo has a more simplified or modern vocabulary. For example, the term for 'to wander,' 'to walk,' or 'to stroll' in Urban Hiligaynon is lágaw , which is also widely used by most of the Hiligaynon speakers, whereas in Standard Hiligaynon, dayán
8500-457: The province, the majority of which is classified as Mountain Soil (71%), followed by Sandy Loam (12.036%), Silty Clay Loam (4.880%), Clay Loam (4.612%) and Loamy Sand (0.185). The climate of Sultan Kudarat falls under Type IV of Climate (characterized by rain showers or evenly distributed rainfall throughout the year). Heavy rainfall occurs from April to November. Unlike most other provinces in
8600-403: The province. Fishing is an industry in the three coastal towns of the province (Kalamansig, Lebak and Palimbang). Tuna caught along the coasts along the Celebes Sea are exported to Japan and Europe. Other economic activities include cottage industries , which include crafts made of rattan and other types of wood. Metallic minerals, which include copper, gold and silver, are found within
8700-442: The province: Alip , Allah , Kapingkong , Tran , Salaman , Palimbang and Kabulnan . Additionally, there are 23 large creeks and 11 major springs within the province. Forestland constitutes the majority of the province's land use (50.32% ), followed by agricultural land (44.77%), fishing grounds (2.42%), non-agricultural land (1.16%), "other bodies of water" (1.02%), and fishponds (0.31%). Five major soil types are found within
8800-632: The region. Sultan Kudarat was part of the former province of Cotabato , until its creation as an independent province (along with Maguindanao and North Cotabato ) on November 22, 1973, through Presidential Decree No. 341 . One notable event that took place in Sultan Kudarat was the Palimbang Massacre (also called the Malisbong Masjid Massacre ), which saw the mass murder of Moro residents of Barrio Malisbong in Palimbang by units of
8900-554: The remainders such as the Evangelical Christians , United Church of Christ in the Philippines , Jehovah's Witnesses , United Methodist Church , Southern Baptists, as well as "tribal religions". In 2015 the Philippine Statistics Authority recorded Islam followed by 29.48% of the population. Poverty incidence of Sultan Kudarat Source: Philippine Statistics Authority The economy of Sultan Kudarat
9000-605: The results. Analysis of the effects of shallow and deep underwater explosions indicate that the energy of the explosions does not easily generate the kind of deep, all-ocean waveforms typical of tsunamis because most of the energy creates steam , causes vertical fountains above the water, and creates compressional waveforms. Tsunamis are hallmarked by permanent large vertical displacements of very large volumes of water which do not occur in explosions. Tsunamis are caused by earthquakes, landslides, volcanic explosions, glacier calvings, and bolides . They cause damage by two mechanisms:
9100-426: The sea and a following gigantic wave, after the 365 AD tsunami devastated Alexandria . The principal generation mechanism of a tsunami is the displacement of a substantial volume of water or perturbation of the sea. This displacement of water is usually caused by earthquakes, but can also be attributed to landslides, volcanic eruptions, glacier calvings or more rarely by meteorites and nuclear tests. However,
9200-911: The shortest at 107.38 kilometres (66.72 mi). Sultan Kudarat has two seaports: the Port of Lebak in Kalamansig and the San Roque Port in Palimbang, and four airports (2 government-owned: Lebak Municipal Airport and President Quirino Airport, and 2 privately owned: Kalamansig Airport and Kenram Airport). The following are the elected government officials and their years of tenure: Elected Officials (2016-2019) : Elected Officials (2010-2013) : Elected Officials (2007-2010) : Elected Officials (2004-2007) : Elected Officials (1998-2000; 2000–2004) : Elected Officials (1995-1998) : Elected Officials (1992-1995) : The former governors who have administered
9300-400: The smashing force of a wall of water travelling at high speed, and the destructive power of a large volume of water draining off the land and carrying a large amount of debris with it, even with waves that do not appear to be large. While everyday wind waves have a wavelength (from crest to crest) of about 100 metres (330 ft) and a height of roughly 2 metres (6.6 ft), a tsunami in
9400-480: The three autochthonous ethnic groups of the province. Ilocanos and Cebuanos meanwhile are relative newcomers to the province, with the former comprising the majority of the population in the towns of Lambayong and President Quirino, and the latter in the town of Kalamansig. The four major religious groups in Sultan Kudarat are Islam (48.37%), Catholic (30.27%), Iglesia ni Cristo (2.05%), and Seventh-day Adventists (1.49%). Other Christian groups constitute most of
9500-457: The transoceanic reach of significant seismic tsunamis, and 2) that the force that displaces the water is sustained over some length of time such that meteotsunamis cannot be modelled as having been caused instantaneously. In spite of their lower energies, on shorelines where they can be amplified by resonance, they are sometimes powerful enough to cause localised damage and potential for loss of life. They have been documented in many places, including
9600-447: The understanding of the other source mechanisms. Some meteorological conditions, especially rapid changes in barometric pressure, as seen with the passing of a front, can displace bodies of water enough to cause trains of waves with wavelengths. These are comparable to seismic tsunamis, but usually with lower energies. Essentially, they are dynamically equivalent to seismic tsunamis, the only differences being 1) that meteotsunamis lack
9700-457: The use of other terms for landslide-generated waves, including landslide-triggered tsunami , displacement wave , non-seismic wave , impact wave , and, simply, giant wave . While Japan may have the longest recorded history of tsunamis, the sheer destruction caused by the 2004 Indian Ocean earthquake and tsunami event mark it as the most devastating of its kind in modern times, killing around 230,000 people. The Sumatran region
9800-399: The very largest tsunamis, the approaching wave does not break , but rather appears like a fast-moving tidal bore . Open bays and coastlines adjacent to very deep water may shape the tsunami further into a step-like wave with a steep-breaking front. When the tsunami's wave peak reaches the shore, the resulting temporary rise in sea level is termed run up . Run up is measured in metres above
9900-576: Was among the deadliest natural disasters in human history, with at least 230,000 people killed or missing in 14 countries bordering the Indian Ocean . The Ancient Greek historian Thucydides suggested in his 5th century BC History of the Peloponnesian War that tsunamis were related to submarine earthquakes , but the understanding of tsunamis remained slim until the 20th century, and much remains unknown. Major areas of current research include determining why some large earthquakes do not generate tsunamis while other smaller ones do. This ongoing research
10000-515: Was confirmed in 1958, when a giant landslide in Lituya Bay , Alaska, caused the highest wave ever recorded, which had a height of 524 metres (1,719 ft). The wave did not travel far as it struck land almost immediately. The wave struck three boats—each with two people aboard—anchored in the bay. One boat rode out the wave, but the wave sank the other two, killing both people aboard one of them. Another landslide-tsunami event occurred in 1963 when
