Vertical evacuation, as shown in the film, is a good response. That was portrayed well, with Dwayne Johnson noting the drop/retreat of water-levels prior to the arrival of the tsunami, which allows people to take action to seek safety. In the movie, we commend the hero’s recognition of the onset of a tsunami-event. This will not cause significant vertical motion of the ocean floor that is needed to create a widespread, damaging tsunami. While a part of the fault near and north of the San Francisco Bay Area is offshore, the blocks on either side of the fault slide past each other horizontally. It is also important to note that - unlike in the movie, San Andreas - the San Andreas Fault cannot create a massive tsunami. Still, large seismic events have occurred in Nevada in the 20th Century. While a magnitude 7+ earthquake is possible in Nevada, there is no direct connection between faults located in the state of Nevada and the San Andreas fault in California. But a large San Andreas fault earthquake would be felt over a large region of California and neighboring areas, as was observed in the magnitude-7.9 San Francisco earthquake of 1906. Also, contrary to what is mentioned in the movie San Andreas, any earthquake on the San Andreas Fault – no matter how large – would not be felt on the East Coast of the U.S. Crevices may form due to bends in the fault or in regions with very strong shaking. In a strike-slip fault, such as the San Andreas Fault, the ground on the two sides of the fault slide past each they do not pull apart. Secondly, faults do not split apart, leaving a gaping chasm, as shown in the movie. On the positive side, the film’s hero – an LAFD Firefighter portrayed by Dwayne “The Rock” Johnson – orders people to Drop, Cover, and Hold-On, which is the recommended best practice during an earthquake to protect yourself from injury … no matter where you are.
However, it is possible that some older buildings that were built prior to the establishment of modern building codes might collapse during prolonged, severe ground motions.
Modern building codes are designed to prevent buildings from collapsing during an earthquake. And there are several inaccuracies in the movie San Andreas that require clarification.įirst, the strength of the ground shaking and the widespread collapse of buildings depicted in the movie is unrealistic. It’s important to note that what makes an entertaining and dramatic disaster movie may not be reality. It offers us a teachable moment, to separate the myths from reality about earthquakes. So, in that sense, San Andreas is more than just escapist disaster-porn. The release of the movie, and the recent deadly earthquake in Nepal have many people thinking about earthquakes and how to prepare for the so-called “Big One”. Warner Brothers has just released the motion picture San Andreas, which portrays a major earthquake on the San Andreas fault, and its affect on California and elsewhere.
