My topic is on earthquake danger for the United States. On this page you will find all the information you need along with photos, information, websites, and more. This page contains many facts, and some opinions. As you can see, there are many ways this page will help you learn more about earthquakes.

The answer is that earthquakes are caused by faulting. Faulting is a sudden lateral or movement of rock along a rupture surface. Plate tectonics are rigid plates at the surface of the Earth in response to flow of the rock in the Earth. The plates cover the entire surface of the globe. Since they are all moving they slide against each other in some places (like the San Andreas Fault in California), sink beneath each other in others (like the Peru-Chile Trench along the western border of South)

Earthquake History
In camp about 30 miles southeast of Los Angeles center. Most authorities speculate, even though the record is very incomplete, that this was a major earthquake. Forty people attending church at San Juan Capistrano on December 8, 1812, were killed by a strong earthquake that destroyed the church. Many mission buildings were severely damaged there and at San Gabriel. The shock centered on a submarine fault offshore.[2] This earthquake is one of the most devastating in the history of California. The earthquake and resulting fires caused an estimated 3,000 deaths and $524 million in property loss. Damage in San Francisco resulting only from the earthquake was estimated at $20 million; outside the city, it was estimated at $4 million. The sensible duration of the shaking in San Francisco was about 1 minute.[5] The earthquake damaged buildings and structures in all parts of the city and county of San Francisco, although over much of the area, the damage was moderate in amount and character. Most chimneys toppled or were badly broken. In the business district, which was built on ground made by filling in the cove of Yerba Buena, pavements were buckled, arched, and fissured; brick and frame houses of ordinary construction were damaged extensively or destroyed; sewers and water mains were broken; and streetcar tracks were bent into wavelike form. On or near the San Andreas fault, buildings were destroyed (one was torn apart), and trees were knocked to the ground. The surface of the ground was torn and heaved into furrow-like ridges. Roads crossing the faultline were impassable, and pipelines were broken. One pipeline that carried water from San Andreas Lake to San Francisco was broken, shutting off the water supply to the city. The fires that ignited soon after the onset of the earthquake quickly raged through the city because of the lack of water to control them. They destroyed a large part of San Francisco and intensified the loss at Fort Bragg and Santa Rosa.[6]

San Francisco Earthquake, 1906.[1]

Earthquakes
They strike without no one nowing allowing no time for preparing or evacuation. Nationwide, about thirty nine states are considered at risk from moderate to great big earthquakes. Earthquakes have striked many areas of the United States, including Alaska and the Central and East Coast states.

The Northridge earthquake resulted in over sixty deaths, more than five thousand injuries, and over twentty five people left homeless, and it occurred in the early morning of a holiday.[3] Direct economic losses from the Northridge earthquake are estimated at about $25 billion. But the Northridge earthquake was not even the big one! It was a large (magnitude 6.7) but not a great earthquake, of relatively short duration (the main shock lasting roughly fifteen seconds). By contrast, the 1906 San Francisco earthquake was about 8.3 magnitude lasting forty five seconds. The 1964 Alaska earthquake (magnitude 8.4) lasted over three minutes.[8] __References__
