In the film, there has been continuous vibration San Andreas fault, from Los Angeles to San Francisco left a huge fracture traces, skyscrapers collapse, fire broke out, the Hollywood sign has been destroyed by the tsunami rocked the Golden Gate Bridge. San Andreas has long been considered a possible outbreak of the earthquake, and is one of the most dangerous earthquake fault length of about 800 miles, like a scar through California and nearby Nevada's Hoover Dam, etc. building.
According to the film's plot, northern California earthquake broke out in 9.6, 9.1 earthquake in southern emerged, but the US Geological Survey seismologists believe that although the San Andreas Fault is a dangerous place, but not likely to occur nine strong shock, because the fault dislocation deep enough. US seismologists warned that the risk of the outbreak of the San Andreas fault does exist, and there is no warning.
In 1960, Chile 9.5 magnitude earthquake, the reason comes into the continental plate subduction zone beneath the earthquake is the current world record holder. In 2008, the US Geological Survey organized nearly 300 experts formed a study group to conduct a comprehensive study on the San Andreas fault, aimed to establish a scientific background of crisis early warning mechanism, it can be used for earthquake preparedness drills .
According to the researchers estimate that the San Andreas fault if an earthquake occurs, will not reach 9 size, but may reach 7.8 to 8.3, is expected to have 1,800 people were killed and five people were injured. Some old buildings, concrete structure will collapse, high-rise buildings will be affected. According to the San Andreas Fault simulation research scientists, and 8.3 is the upper limit is greater than the 8.3 earthquake almost does not occur.
Movie Caltech seismologist Lawrence - Hayes found nearby magnetic pulse California peaked, indicating that the earthquake is going to happen, but in reality, this method is not correct, the study of earthquakes in the past century scientistsstill we have not found such a law, now our study of earthquakes can not be predicted. Earthquake prediction may flag animal behavior, weather patterns and the like.
US National Geological Survey scientist trying to find a reliable precursor, on the San Andreas Fault study continues. Scientists believe that hope to establish an early warning system that can give residents a few seconds of warning time. In this regard, Japan's technology strongest, has the world's most advanced earthquake early warning system, the United States is currently being tested such a system. But scientists believe that the San Andreas fault will not produce a tsunami, most from undersea earthquake tsunami.
Massive tsunami needs drastic changes crust, the place of the original seawater, once tsunami size increases, so across the ocean to the coast constitute the greater destructive power. In 1906, San Francisco 7.8 earthquake, about 3,000 people were killed and more than 80 percent of the buildings were destroyed.
