The 1906 San Francisco earthquake occurred in California on April 18th, 1906. It mainly hit the San Francisco Bay area. Until now, the seism still ranks as one of the most significant earthquakes, not only because its sheer size, but wealth of scientific knowledge derived from it as well. Although the magnitude of the earthquake has been redetermined through different approaches, with the magnitude range from 7.7 to 8.3, it is no doubt that the San Francisco earthquake is a catastrophe. What’s more, the total length of 1906 rupture seen at the surface is 296 miles, the offset observed at the surface was 20 feet, the shaking has lasted 45 to 60 seconds, the ground has moved at a speed of 3 miles per hour approximately. The San Francisco earthquake is truly a big one, and from these data, we could still imagine the misery scene of offset fence and the train fell …show more content…

When an earthquake comes, a real tragedy is on. What makes things worse is that for a long period of time, the temblor was tagged as mysterious and unpredictable. Except for suffering from it, one can do nothing to resist it. Toady, an earthquake is still seen as a big catastrophe, but we already know more about it. We understand the forms of one quake and build the principal model of the earthquake cycle (elastic-rebound theory). We create plate tectonic theory and have some precise instrument to help us predict when the quake will occur. In the temblor that occurred in the international waters of the western Pacific on Mar 11th, 2011, the prediction of the quake won 60 seconds for the local people, and a large number of people were saved because of it. That is really amazing. It is obvious that the more we know about the earthquake, the less we suffer from it, and one efficient way to get the earthquake knowledge is to dedicate in the happened earthquake and finding the rules and theories hidden in
