The major reason for the high frequency and intensity of the earthquakes is that the Indian plate is driving into Asia at a rate of approximately 47 mm/year. Geographical statistics of India show that almost 54% of the land is vulnerable to earthquakes. A World Bank & United Nations report shows estimates that around 200 million city dwellers in India will be exposed to storms and earthquakes by 2050. National Disaster Management Authority says that 60% of Indian landmass

In the west it is bounded by parts of the mountain ranges of Hindu Kush , Spīn Ghar (Safed Koh), Sulaiman Mountains , Kirthar Mountains , Brahui range, and Pab range among others, with the Western Fold Belt along
7725-577: The era of the British Raj. Over time, however, "India" evolved to refer to a distinct political entity that eventually became a nation-state (today the Republic of India). According to the Oxford English Dictionary , the term subcontinent signifies a "subdivision of a continent which has a distinct geographical, political, or cultural identity" and also a "large land mass somewhat smaller than
7828-513: The fact that for most of the languages involved, there was no alphabet until the early twentieth century—and only began to be written down in the late nineteenth century. One important tradition is that of the Nart sagas , which tell stories of a race of ancient heroes called the Narts. These sagas include such figures as Satanaya , the mother of the Narts, Sosruquo a shape changer and trickster, Tlepsh
7931-590: The final break from Gondwana. In the early Tertiary, the first phase of the Himalayan orogeny, the Karakoram phase occurred. The Himalayan orogeny has continued to the present day. Greater India or the Greater India Basin means the Indian Plate plus a postulated northern extension which was squashed out of easy recognizability in the Indian–Asia collision. The term was used before plate tectonic theory, but
8034-421: The first century BC, Zoroastrianism had become the dominant religion of the region; however, the region would go through two other religious transformations. Owing to the strong rivalry between Persia and Rome , and later Byzantium . The Romans first arrived in the region in the 1st century BC with the annexation of the kingdom of Colchis, which was later turned into the province of Lazicum . The next 600 years
8137-459: The gift of fire, Prometheus (or Amirani in the Georgian version ) was chained there by Zeus , to have his liver eaten daily by an eagle as punishment for defying Zeus's wish to keep the "secret of fire" from humans. In Persian mythology , the Caucasus might be associated with the mythic Mount Qaf which is believed to surround the known world. It is the battlefield of Saoshyant and the nest of
8240-540: The iconic Ediacaran fossil "Dickinsonia" located in the Upper Bhander (Retallack et al., 2021) required an Ediacaran age for that Group; however, Meert et al. (2023) demonstrated that the fossil was misidentified and therefore the age of the Upper Vindhyan is still debated. Early Paleozoic rocks are found in the Himalayas and consist of southerly derived sediments eroded from the crystalline craton and deposited on
8343-755: The limestones of the Permo-Triassic, which has led to these rocks being referred to as "productus limestone". This limestone is of marine origin and is divided into three distinct lithostratigraphic units based on the productus chronology: the Late Permian Chideru, which contains many ammonites, the Late ;— Middle Permian Virgal, and the Middle Permian Amb unit. In the Triassic the Ceratite beds, named after
8446-416: The most fertile soil found in the country as new silt is continually laid down by the rivers every year. The Indian subcontinent has a history of devastating earthquakes . The Assam earthquake of 1950 registered a magnitude of 8.6; it is one of the most powerful earthquakes to have ever been recorded. A similar earthquake in a densely populated area today would kill hundreds of thousands if not millions. This
8549-480: The name means shining white like snow: Thus, toward the east, where it rises to a greater height, it is called the Caucasus, due to the whiteness of its snow, for in an eastern language, caucasus means "white," that is, shining white with a very thick snow cover. For the same reason the Scythians, who live next to this mountain range, call it Croacasim, for among them whiteness or snow is called casim. 3. The Taurus range
8652-429: The natural and historical boundary between Europe and Asia. Another opinion is that the rivers Kura and Rioni mark this border, or even that of the river Aras . The Caucasus is a linguistically , culturally and geographically diverse region. The nation states that compose the Caucasus today are the post-Soviet states Georgia (including Adjara and Abkhazia ), Azerbaijan (including Nakhchivan ), Armenia , and
8755-417: The north is mostly shared by Russia and Georgia as well as the northernmost parts of Azerbaijan . The Lesser Caucasus mountain range in the south is occupied by several independent states, mostly by Armenia, Azerbaijan, and Georgia, but also extends to parts of northeastern Turkey , and northern Iran . The region is known for its linguistic diversity : aside from Indo-European and Turkic languages,
8858-516: The north of the Greater Caucasus range practically impregnable. The mythological Mount Qaf , the world's highest mountain that ancient Iranian lore shrouded in mystery, was said to be situated in this region. The region is also one of the candidates for the location of Airyanem Vaejah , the apparent homeland of the Iranians of Zoroaster . In Middle Persian sources of the Sasanian era, the Caucasus range
8961-420: The region is referred to as South Asia. The periphery of the subcontinent, including Bangladesh, Pakistan, and the island chains of Maldives, features large Muslim populations, while the heartland, including most of India, Nepal, and Sri Lanka, are overwhelmingly Hindu or Buddhist. Since most of these countries are located on the Indian Plate, a continuous landmass , the borders between countries are often either
9064-456: The region's contemporary political demarcations, is replacing the Indian subcontinent , a term closely linked to the region's colonial heritage, as a cover term, the latter is still widely used in typological studies. Since the Partition of India , citizens of Pakistan (which became independent of British India in 1947) and Bangladesh (which became independent of Pakistan in 1971) often perceive
9167-729: The same age as the Dharwar system. The metamorphic basement consists of gneisses which are further classified into the Bengal gneiss, the Bundelkhand gneiss and the Nilgiri gneiss. The Nilgiri system comprises charnockites ranging from granites to gabbros . Rocks of the earliest part of the Cambrian Period are found in the Salt range in Punjab and the Spiti area in the central Himalayas and consist of
9270-748: The sedimentary rocks are divided into four stages; the Niniyur, the Ariyalur, the Trichinopoly(a district in the Madras Presidency, covering present-day districts of Tiruchirappalli, Karur, Ariyalur and Perambalur), and the Utatur stages. In the Utatur stage the rocks host phosphate nodules , which constitute an important source of phosphates in the country. In the central provinces, the well developed beds of Lameta contain fossil records which are helpful in estimating
9373-579: The southwest and the Bay of Bengal to the southeast. Most of this region rests on the Indian Plate and is isolated from the rest of Asia by large mountain barriers. Laccadive Islands , Maldives and the Chagos Archipelago are three series of coral atolls , cays and Faroes on the Indian Plate along with the Chagos–Laccadive Ridge , a submarine ridge that was generated by the northern drift of
9476-744: The term Caucasus is derived from Caucas ( Georgian : კავკასოსი Ḳavḳasosi ), the son of the Biblical Togarmah and legendary forefather of the Nakh peoples . According to German philologists Otto Schrader and Alfons A. Nehring, the Ancient Greek word Καύκασος ( Kaukasos ) is connected to Gothic hauhs 'high' as well as Lithuanian kaũkas 'hillock' and kaukarà 'hill, top', Russian куча 'heap'. British linguist Adrian Room claims that * kau- also means 'mountain' in Pelasgian , though this
9579-547: The term has seen increased usage since the 1970s. The Indian Plate and the Eurasian Plate have converged up to 3,600 km (2,200 mi) ± 35 km (22 mi). The upper crustal shortening is documented from the geological record of Asia and the Himalaya as up to approximately 2,350 km (1,460 mi) less. Much of the lost area was pushed under Asia to form the Tibetan highland. A considerable area of peninsular India,
9682-444: The terms "Indian subcontinent" and "South Asia" are often used interchangeably to denote the region, the geopolitical term of South Asia frequently includes Afghanistan , which is not considered a part of the subcontinent, while excluding the British Indian Ocean Territory which is geologically associated with the subcontinent. Geologically, the subcontinent originates from Insular India , an isolated landmass that rifted from
9785-679: The upper Carboniferous Po, and the lower Carboniferous Lipak. Fossils of brachiopods and some trilobites are found in the calcareous and sandy rocks of the Lipak series. The Syringothyris limestone in Kashmir also belongs to the Lipak. The Po series overlies the Lipak series, and the Fenestella shales are interbedded within a sequence of quartzites and dark shales. In many places Carboniferous strata are overlaid by grey agglomeratic slates, believed to be of volcanic origin. Many genera of productids are found in
9888-438: The use of the Indian subcontinent as offensive and suspicious because of the dominant placement of India in the term. As such it is being increasingly less used in those countries. Meanwhile, many Indian analysts prefer to use the term because of the socio-cultural commonalities of the region. The region has also been called the "Asian subcontinent", the "South Asian subcontinent", as well as "India" or " Greater India " in
9991-605: The volcanism associated with the Deccan Traps continued. The rocks of this era have valuable deposits of petroleum and coal. Sandstones of Eocene age are found in Punjab, which grade into chalky limestones with oil seepages. Further north the rocks found in the Simla area are divided into three series, the Sabathu series consisting of grey and red shales , the Dagshai series of bright red clays and
10094-417: The world community as part of Georgia. The region has many different languages and language families. There are more than 50 ethnic groups living in the region. No fewer than three language families are unique to the area. In addition, Indo-European languages, such as East Slavic , Armenian and Ossetian , and Turkic languages , such as Azerbaijani , Kumyk language and Karachay–Balkar , are spoken in
10197-566: Was attached to Madagascar and southern Africa, and what is now its east coast was attached to Australia. During the Jurassic Period about 160 Ma ( ICS 2004), rifting caused Pangaea to break apart into two supercontinents, namely Gondwana (to the south) and Laurasia (to the north). The Indian Craton remained attached to Gondwana , until the supercontinent began to rift apart about in the early Cretaceous , about 125 million years ago (ICS 2004). The Indian Plate then drifted northward toward
10300-537: Was formerly part of Gondwana , a supercontinent formed during the late Neoproterozoic and early Paleozoic . Gondwana began to break up during the Mesozoic , with Insular India separating from Antarctica 130-120 million years ago and Madagascar around 90 million years ago, during the Cretaceous . Insular India subsequently drifted northeastwards, colliding with the Eurasian Plate nearly 55 million years ago, during
10403-583: Was marked by a conflict between Rome and Sassanid Empire for the control of the region. In western Georgia the eastern Roman rule lasted until the Middle Ages. As the Arsacid dynasty of Armenia (an eponymous branch of the Arsacid dynasty of Parthia ) was the first nation to adopt Christianity as state religion (in 301 AD), and Caucasian Albania and Georgia had become Christian entities, Christianity began to overtake Zoroastrianism and pagan beliefs. With
10506-626: Was moving northward towards Asia. At this time, prior to the Deccan eruptions, uplift in southern India resulted in sedimentation in the adjacent nascent Indian Ocean. Exposures of these rocks occur along the south Indian coast at Pondicherry and in Tamil Nadu. At the close of the Mesozoic one of the greatest volcanic eruptions in earth's history occurred, the Deccan lava flows . Covering more than 500,000 square kilometres (193,051 sq mi) area, these mark
10609-639: Was referred to as Kaf Kof . The term resurfaced in Iranian tradition later on in a variant form when Ferdowsi , in his Shahnameh , referred to the Caucasus mountains as Kōh-i Kāf . "Most of the modern names of the Caucasus originate from the Greek Kaukasos (Lat., Caucasus ) and the Middle Persian Kaf Kof ". "The earliest etymon" of the name Caucasus comes from Kaz-kaz , the Hittite designation of
