The main airport for the metropolitan area is Harry Reid International Airport , northwest of Henderson. Street numbering

396-422: A practical method of assigning an absolute measure of magnitude. First, to span the wide range of possible values, Richter adopted Gutenberg's suggestion of a logarithmic scale, where each step represents a tenfold increase of magnitude, similar to the magnitude scale used by astronomers for star brightness . Second, he wanted a magnitude of zero to be around the limit of human perceptibility. Third, he specified

462-469: A seismogram recorded by a Wood-Anderson torsion seismometer. Finally, Richter calculated a table of distance corrections, in that for distances less than 200 kilometers the attenuation is strongly affected by the structure and properties of the regional geology. When Richter presented the resulting scale in 1935, he called it (at the suggestion of Harry Wood) simply a "magnitude" scale. "Richter magnitude" appears to have originated when Perry Byerly told

The following describes the typical effects of earthquakes of various magnitudes near the epicenter. The values are typical and may not be exact in a future event because intensity and ground effects depend not only on the magnitude but also on (1) the distance to the epicenter, (2) the depth of

594-531: A shallow earthquake in a populated area with soil of certain types can be far more intense in impact than a much more energetic deep earthquake in an isolated area. Several scales have been historically described as the "Richter scale", , especially the local magnitude M L   and the surface wave M s   scale. In addition, the body wave magnitude , mb , and the moment magnitude , M w  , abbreviated MMS, have been widely used for decades. A couple of new techniques to measure magnitude are in

Although values measured for earthquakes now are M w  , they are frequently reported by the press as Richter values, even for earthquakes of magnitude over 8, when the Richter scale becomes meaningless. The Richter and MMS scales measure the energy released by an earthquake; another scale, the Mercalli intensity scale , classifies earthquakes by their effects , from detectable by instruments but not noticeable, to catastrophic. The energy and effects are not necessarily strongly correlated;

1980-652: The United States War Asset Administration offered Henderson for sale as war surplus property. With the help of local industry, Henderson was incorporated on April 16, 1953, as the City of Henderson. On May 23, 1953, Henderson, with its population of 7,410, elected Dr. Jim French as the first mayor. Originally only about 13 square miles (34 km ) in size, the city quickly began to grow, reaching over 100 square miles (260 km ) in size in 2022.

The per capita income for the city

2244-407: The amplitude of a precisely defined wave. All scales, except M w  , saturate for large earthquakes, meaning they are based on the amplitudes of waves that have a wavelength shorter than the rupture length of the earthquakes. These short waves (high-frequency waves) are too short a yardstick to measure the extent of the event. The resulting effective upper limit of measurement for M L  

2310-413: The amplitudes of different types of elastic waves must be measured. M L   is the scale used for the majority of earthquakes reported (tens of thousands) by local and regional seismological observatories. For large earthquakes worldwide, the moment magnitude scale (MMS) is most common, although M s   is also reported frequently. The seismic moment , M 0   , is proportional to

2376-402: The area of the rupture times the average slip that took place in the earthquake, thus it measures the physical size of the event. M w   is derived from it empirically as a quantity without units, just a number designed to conform to the M s   scale. A spectral analysis is required to obtain M 0  . In contrast, the other magnitudes are derived from a simple measurement of

2706-449: The development stage by seismologists. All magnitude scales have been designed to give numerically similar results. This goal has been achieved well for M L  , M s  , and M w  . The mb  scale gives somewhat different values than the other scales. The reason for so many different ways to measure the same thing is that at different distances, for different hypocentral depths, and for different earthquake sizes,

2772-426: The earthquake's focus beneath the epicenter, (3) the location of the epicenter, and (4) geological conditions . ( Based on U.S. Geological Survey documents. ) The intensity and death toll depend on several factors (earthquake depth, epicenter location, and population density, to name a few) and can vary widely. Millions of minor earthquakes occur every year worldwide, equating to hundreds every hour every day. On

2838-483: The earthquake. The original formula is: where A is the maximum excursion of the Wood-Anderson seismograph , the empirical function A 0 depends only on the epicentral distance of the station, δ {\displaystyle \delta } . In practice, readings from all observing stations are averaged after adjustment with station-specific corrections to obtain the M L   value. Because of

2904-897: The energy released. The elastic energy radiated is best derived from an integration of the radiated spectrum, but an estimate can be based on mb  because most energy is carried by the high-frequency waves. These formulae for Richter magnitude   M L   {\displaystyle \ M_{\mathsf {L}}\ } are alternatives to using Richter correlation tables based on Richter standard seismic event (   M L = 0   , {\displaystyle {\big (}\ M_{\mathsf {L}}=0\ ,}   A = 0.001   m m   , {\displaystyle \ A=0.001\ {\mathsf {mm}}\ ,}   D = 100   k m   )   . {\displaystyle \ D=100\ {\mathsf {km}}\ {\big )}~.} In

2970-489: The epicenter. He then plotted the logarithm of the amplitude against the distance and found a series of curves that showed a rough correlation with the estimated magnitudes of the earthquakes. Richter resolved some difficulties with this method and then, using data collected by his colleague Beno Gutenberg , he produced similar curves, confirming that they could be used to compare the relative magnitudes of different earthquakes. Additional developments were required to produce

3036-502: The explosion on May 4, 1988. The blaze quickly engulfed the factory, smoke, and flames from the building, eventually obliterating it in a massive explosion, followed by six smaller explosions. Smoke was seen from 100 miles (160 km) away, and two major blasts measured 3.0 and 3.5, respectively, on the Richter magnitude scale at observatories in California and Colorado . These explosions sent shockwaves throughout Henderson and parts of

3102-454: The intensity of shaking observed near the epicenter of the earthquake, categorized by various seismic intensity scales such as the Rossi–Forel scale . ("Size" is used in the sense of the quantity of energy released, not the size of the area affected by shaking, though higher-energy earthquakes do tend to affect a wider area, depending on the local geology.) In 1883, John Milne surmised that

3168-502: The largest one of its kind in Nevada. Henderson has more than 37 miles (60 km) of trails. The city received its charter from the Nevada State Legislature in 1953, formally incorporating the city with a council/manager form of government. Henderson is divided into four wards. A mayor and four council members are elected citywide, but no more than one council member are allowed to reside in each ward. Lorna Kesterson

3234-421: The logarithmic basis of the scale, each whole number increase in magnitude represents a tenfold increase in measured amplitude. In terms of energy, each whole number increase corresponds to an increase of about 31.6 times the amount of energy released, and each increase of 0.2 corresponds to approximately a doubling of the energy released. Events with magnitudes greater than 4.5 are strong enough to be recorded by

3300-476: The matter voluntarily. The city expressed its full commitment to ensure compliance with the ADA. Under the settlement, the city of Henderson will pay $ 35,000 to the complainants. The city agreed to provide sign language interpreters, usually within an hour of a person's request to law enforcement officers. Henderson also agreed to modify its handcuffing policies for people who use sign language or hand writing to communicate, and to adopt other policies consistent with

3366-412: The measurements manageable (i.e., a magnitude 3 quake factors 10³ while a magnitude 5 quake factors 10 and has seismometer readings 100 times larger). The Richter magnitude of an earthquake is determined from the logarithm of the amplitude of waves recorded by seismographs. Adjustments are included to compensate for the variation in the distance between the various seismographs and the epicenter of

3432-561: The metal from its ore by electrolysis . Although "born in America's defense", Henderson's future after World War II was uncertain. In 1947, magnesium production was no longer necessary for defense, and most of the Black Mountain Industrial (BMI) Complex's 14,000 employees moved away. Enrollment in the school system was reduced by two thirds, and well over half the townsite houses, built to house plant workers, became vacant. In 1947,

3498-512: The other hand, earthquakes of magnitude ≥8.0 occur about once a year, on average. The largest recorded earthquake was the Great Chilean earthquake of May 22, 1960, which had a magnitude of 9.5 on the moment magnitude scale . Seismologist Susan Hough has suggested that a magnitude 10 quake may represent a very approximate upper limit for what the Earth's tectonic zones are capable of, which would be

3564-425: The particular circumstances refer to it being defined for Southern California and "implicitly incorporates the attenuative properties of Southern California crust and mantle." The particular instrument used would become saturated by strong earthquakes and unable to record high values. The scale was replaced in the 1970s by the moment magnitude scale (MMS, symbol M w  ); for earthquakes adequately measured by

3630-442: The press that the scale was Richter's and "should be referred to as such." In 1956, Gutenberg and Richter, while still referring to "magnitude scale", labelled it "local magnitude", with the symbol M L  , to distinguish it from two other scales they had developed, the surface-wave magnitude (M S ) and body wave magnitude (M B ) scales. The Richter scale was defined in 1935 for particular circumstances and instruments;

3696-684: The result of the largest known continuous belt of faults rupturing together (along the Pacific coast of the Americas). A research at the Tohoku University in Japan found that a magnitude 10 earthquake was theoretically possible if a combined 3,000 kilometres (1,900 mi) of faults from the Japan Trench to the Kuril–Kamchatka Trench ruptured together and moved by 60 metres (200 ft) (or if
