San Francisco earthquake of 1906 was a major earthquake that struck San Francisco and the coast of northern California at 5:12am on Wednesday, April 18, 1906. The most widely accepted magnitude for the earthquake is a moment magnitude (Mw) 7.8; however, other values have been proposed from 7.7 to as high as 8.3 [1]. The mainshock epicenter occurred offshore about 2 miles from the city. It ruptured along the San Andreas Fault both northward and southward for a total length of 296 miles (477 km)[2]. Shaking was felt from Oregon to Los Angeles, and inland as far as central Nevada. The earthquake and resulting fire would be remembered as one of the worst natural disasters in the history of the United States, comparable in devastation to the Galveston Hurricane of 1900 and Hurricane Katrina in 2005.\nContents\n[hide]\n\n    * 1 Geology\n    * 2 Subsequent fires\n    * 3 Relocation and housing of displaced\n    * 4 Aftermath & reconstruction\n    * 5 Centennial commemorations\n    * 6 Analysis\n    * 7 References\n    * 8 See also\n    * 9 External links\n\nAt the time, only 478 deaths were reported; the figure was concocted by government officials who felt that reporting the true death toll would hurt real estate prices and efforts to rebuild the city. Furthermore, hundreds of casualties in Chinatown went ignored and unrecorded due to racism at the time. This figure has been revised to today's conservative estimate of at least 3000; some estimates have put it as high as 6000. Most of the deaths occurred in San Francisco itself, but 189 were reported elsewhere across the San Francisco Bay Area. Other places in the Bay Area such as Santa Rosa, San Jose, and Stanford University also suffered severe damage.\nHouses damaged by the earthquake.\nEnlarge\nHouses damaged by the earthquake.\n\nBetween 225,000 and 300,000 people were left homeless out of a population of about 400,000. Half of the refugees fled across the bay to Oakland. Newspapers at the time described Golden Gate Park, the Presidio, the Panhandle, and the beaches between Ingleside and North Beach being covered with makeshift tents.\n\nThe earthquake and fire would leave a long-standing and significant impression on the development of California. At the time of the disaster, San Francisco had been the ninth-largest city in the United States and the largest on the West Coast, with a population of about 410,000. Over a period of 60 years, the city had become the financial, trade and cultural center of the West; operated the busiest port on the West Coast; and was the "gateway to the Pacific", through which growing US economic and military power was projected into the Pacific and Asia. Over 80% of the city was destroyed by the earthquake and fire. Though San Francisco would rebuild quickly, the disaster would divert trade, industry and population growth south to Los Angeles, which during the 20th century would become the largest and most important urban area in the West. However, the 1908 Lawson Report, a study of the 1906 quake, showed that the very same San Andreas Fault which had caused the disaster in San Francisco ran close to Los Angeles as well.\n\nThe earthquake was the first natural disaster of its magnitude to be documented by photography and motion picture footage. Furthermore, it occurred at a time when the science of seismology was blossoming. The overall cost of the damage from the earthquake was estimated at the time to be around $400 million.\n[edit]\n\nGeology\n\nThe 1906 San Francisco earthquake was caused by a slip on the San Andreas Fault. This fault runs the length of California from the Salton Sea in the south to Cape Mendocino to the north, a distance of about 800 miles (1287 km). The earthquake ruptured the northern third of the fault for a distance of 296 miles (477 km). The maximum observed surface displacement was about 20 feet (6 m); however, geodetic measurements indicate displacements of up to 28 feet (8.5 m) [3].\n\nA strong foreshock

September 2006 is still in the future, so that one will be very hard to explain, but there was a 7.6 magnitude quake in Pakistan on October 8, of 2005. This was a complex earthquake, with at least one more event occurring about 5 seconds after the initial onset. \n\nThe earthquake was produced by the northward movement of the India Plate relative to the Eurasian Plate. The rate of motion has been characterized as between 43 and 47 mm/year. There are complex vectors of convergence, divergence, and transform motion taking place in this region. The convergence is being expressed as crustal folding, uplift, thrust faulting and subduction. In the more immediate area around the epicenter of this quake the motion is convergent.\n\nTo see the seismic amplitude and the pattern of the event I suggest you examine these seismograms. You may note the way the event is 'compressed' in the stations nearer to the epicenter and 'spread' as they traveled further.\nHere is a relatively close seismic station at Diego Garcia:\nhttp://neic.usgs.gov/neis/seismogram/2005_10_08/DGAR.html\nHere are a couple of stations in Australia:\nhttp://neic.usgs.gov/neis/seismogram/2005_10_08/MBWA.html\nhttp://neic.usgs.gov/neis/seismogram/2005_10_08/NWAO.html\nHere is one in South Africa:\nhttp://neic.usgs.gov/neis/seismogram/2005_10_08/SUR.html\n \n\nThe epicenter of the quake was 34.493°N, 73.629°E, and the hypocenter was 26 km (16.2 miles) beneath the surface. Relative to the surrounding geography it was located:\n105 km (65 miles) NNE of ISLAMABAD, Pakistan\n115 km (70 miles) ESE of Mingaora, Pakistan\n125 km (75 miles) WNW of Srinagar, Kashmir\n165 km (105 miles) SSW of Gilgit, Kashmir\n\nA map of P-wave travel times can be examined here:\nhttp://neic.usgs.gov/neis/eq_depot/2005/eq_051008_dyae/neic_dyae_t.html\nA total of 280 seismic stations reported this quake and all 280 were included in the calculations of the location and depth. The estimated energy dissapated in the quake was 3.1 x 10^15 Newton meters. \n\nThe earthquake was preceeded by a Magnitude 5.5 on July 23, 2005, a 5.5 on July 15, '05, and a 5.5 on July 1, '05. There have been dozens, if not hundreds of aftershocks, including at least 19 earthquakes in the region that were magnitude 5.0 and higher. On December 12, 2005 a Magnitude 6.7 earthquake occurred in the Hindu Kush region of Afghanistan about 235 km from the epicenter of the 10/8/05 quake. \n\nHere is the main USGS page for that 10/8 earthquake:\nhttp://earthquake.usgs.gov/eqcenter/eqinthenews/2005/usdyae/

The strongest recorded earthquake was the chilean earthquake in '64 I think.  It registered 9.6 on the Richter.  The Good Friday quake in alaska registered 9.4, though was still horribly destructive.

Yes. Earthquake activity in this region is due to plate tectonics. In Kashmir the two plates involved are the Eurasion and Indian tectonic plates. \n\nHere are a few good ways to demonstrate this for elementary school children:\n\n*Have them use their hands with thumbs hooked together and move push one hand forward while pulling one hand back. Force builds up, but when one of the thumbs breaks free both hands makes a big movement (earthquake).\n\n*make playdough "plates" and have slowly pushed together to see uplifting and subduction.\n\n*take model cars/trucks. Predict what would happen if they have met head-on and continue to move. Let cars represent oceanic plates (less dense) and trucks represent continental plates (more dense). This is a good visual to see uplifting (rumpled hoods when they are the same density--car/car or truck/truck) and subduction (truck runs over top of car).\n\nGreat website for kids is:\n\nhttp://earthquake.usgs.gov/learning/kids.php?\n\nGreat website for kids with links to many science websites is:\n\nhttp://members.tripod.com/~ozpk/00000science1-4\n\nHope this helps!

An earthquake is the shaking of the ground caused by an abrupt shift of rock along a fracture in the Earth, called a fault. Within seconds, an earthquake releases stress that has slowly accumulated within the rock, sometimes over hundreds of years. ... \nThe size of an earthquake is indicated by a number called its magnitude. Magnitude is calculated from a measurement of either the amplitude or the duration of specific types of recorded seismic waves. Magnitude is determined from measurements made from seismograms and not on reports of shaking or interpretations of building damage. ... The intensity of and earthquake is a measure of the amount of ground shaking at a particular site, and it is determined from reports of human reaction to shaking, damage done to structures, and other effects. ... \n\nEarth scientists believe that most earthquakes are caused by slow movements inside the Earth that push against the Earth's brittle, relatively thin outer layer, causing the rocks to break suddenly. This outer layer is fragmented into a number of pieces, called plates. Most earthquakes occur at the boundaries of these plates. In Washington State, the small Juan de Fuca plate off the coast of Washington, Oregon, and northern California is slowly moving eastward beneath a much larger plate that includes both the North American continent the land beneath part of the Atlantic Ocean. Plate motions in the Pacific Northwest result in shallow earthquakes widely distributed over Washington and deep earthquakes in the western parts of Washington and Oregon. The movement of the Juan de Fuca plate beneath the North America plate is in many respects similar to the movements of plates in South America, Mexico, Japan, and Alaska, where the world's largest earthquakes occur. ...

Naturally occurring earthquakes\n\nMost naturally occurring earthquakes are related to the tectonic nature of the Earth. Such earthquakes are called tectonic earthquakes. The Earth's lithosphere is a patch work of plates (see plate tectonics) in slow but constant motion caused by the heat in the Earth's mantle and core. Plate boundaries glide past each other, creating frictional stress. When the frictional stress exceeds a critical value, called local strength, a sudden failure occurs. The boundary of tectonic plates along which failure occurs is called the fault plane. When the failure at the fault plane results in a violent displacement of the Earth's crust, the elastic strain energy is released and elastic waves are radiated, thus causing an earthquake. It is estimated that only 10 percent or less of an earthquake's total energy is ultimately radiated as seismic energy, while most of the earthquake's energy is used to power the earthquake fracture growth and is eventually converted into heat. Therefore, earthquakes lower the Earth's available potential energy and thermal energy, though these losses are negligible. To describe the physical process of occurrence of an earthquake, seismologists use the Elastic-rebound theory.\n\nThe majority of tectonic earthquakes originate at depths not exceeding a few tens of kilometers. Earthquakes occurring at boundaries of tectonic plates are called interplate earthquakes, while the less frequent events that occur in the interior of the lithospheric plates are called intraplate earthquakes.\n\nWhere the crust is thicker and colder, earthquakes occur at greater depths of hundreds of kilometers along subduction zones where plates descend into the Earth's mantle. These types of earthquakes are called deep focus earthquakes. They are possibly generated when subducted lithospheric material catastrophically undergoes a phase transition (e.g., olivine to spinel), releasing stored energy—such as elastic strain, chemical energy or gravitational energy—that cannot be supported at the pressures and temperatures present at such depths.\n\nEarthquakes may also occur in volcanic regions and are caused by the movement of magma in volcanoes. Such quakes can be an early warning of volcanic eruptions.\n\nA recently proposed theory suggests that some earthquakes may occur in a sort of earthquake storm, where one earthquake will trigger a series of earthquakes each triggered by the previous shifts on the fault lines, similar to aftershocks, but occurring years later, and with some of the later earthquakes as damaging as the early ones. Such a pattern was observed in the sequence of about a dozen earthquakes that struck the Anatolian Fault in Turkey in the 20th Century, the half dozen large earthquakes in New Madrid in 1811-1812, and has been inferred for older anomalous clusters of large earthquakes in the Middle East and in the Mojave Desert.\n\nInduced earthquakes\nSome earthquakes are the result of a number of anthropogenic sources, such as extraction of minerals and fossil fuel from the Earth's crust, the removal or injection of fluids into the crust, reservoir-induced seismicity, massive explosions, and collapse of large buildings. These seismic events caused by human activity are referred to by the term induced seismicity. They however are not strictly earthquakes and usually show a different seismogram than earthquakes that occur naturally.\n\nA rare few earthquakes have been associated with the build-up of large masses of water behind dams, such as the Kariba Dam in Zambia, Africa, and with the injection or extraction of fluids into the Earth's crust (e.g. at certain geothermal power plants and at the Rocky Mountain Arsenal). Such earthquakes occur because the strength of the Earth's crust can be modified by fluid pressure. Earthquakes have also been known to be caused by the removal of natural gas from subsurface deposits, for instance in the northern Net

Los Angeles and San Francisco would be the big ones but there are a lot of smaller ones in the same danger area. Basically anything that is on or near the San Andreas Fault. Check the map at the link--- actually explore the rest of the site, too--- good info there!

earthquakes occur when the tectonic plates that cover the earth noticably shift. These movements can also form volcanoes and trenches

The possibility exists.. The probability is low. \n\nFor what it's worth, It doesn't require a fault to have an earthquake. Keep that in mind. Shifting plate can happen over areas where tectonic plates are non existent. \n\nThere has been measurable earthquakes in the northeast since recording began. \nEven up to a magnitude 7.. \nBelow is a map of recorded historical earthquakes. \nhttp://earthquake.usgs.gov/regional/states/us_damage_eq.php

I know I am not going to win with this answer but the answer is "All of them".\n\nThe reason stems from the fact that a seismometer placed anywhere on the planet will record motions in the Earth.\n\nSomalia and Ethiopia (and even Sudan, Eritrea and Egypt) lie directly on plate boundaries so they will continuously experience quite large earthquakes.\n\nI know you were probably referring to some big specific event, registering some high value on the Richter magnitude scale, and that I would have to look up somewhere. I don't know where.

The initial shock that lasted 4 minutes knocked out seismographs at the central weather bureau office in Tokyo so that a seismograph in Tokyo Imperial University made the only record of the series of more than 1,700 earthquakes that struck the Tokyo area over the following three days.? The maximum magnitudes of the earthquake measured between 7.9 and 8.3 on the Richter scale, with the epicenter located 50 miles southeast of Tokyo in Sagami Bay.
