SAN ANDREAS TRAILER 1 MOVIE

San Andreas is a strike-slip fault so shearing forces cause slip during an earthquake. I think my colleague Emel Seyhan, a geotechnical engineer who specializes in engineering seismology, summed it up well when she described this crater from a trailer as вЂњtoo long, too wide, and too deepвЂќ to be caused by an earthquake on the San Andreas Fault and like nothing she had ever seen in nature.

For example, the 1906 M7.8 San Francisco Earthquake, which ruptured 477 km of the San Andreas Fault, was only felt as far eastВ as central Nevada.Дo earthquakes cause enormous cracks in the earthвЂ™s surface? CaliforniaвЂ™s geologic features are such that they attenuate earthquake shaking over short distances. A whole pack of them sit not far from my desk, and I promise you that besides big brains, these people have panache.ДЄs to the question: even if we pretend that a M9+ earthquake were to occur in California, the shaking would not be felt on the East Coast, more than 4000 km away. Is this possible?ДЇirst off, why is the movieвЂ™s scientist played by a goofy Paul Giamatti while the search-and-rescue character is played by the muscle-ridden actor Dwayne вЂњThe RockвЂќ Johnson? I know earth scientists. The trailersвЂ™ collapse scenes are good examples of what happens when Hollywood drinks too much coffee.ДЄ character played by Paul Giamatti says that people will feel shaking on the East Coast of the U.S.

California has one of the worldвЂ™s strictest seismic building codes, with the first version published in the early part of the 20thВ century following the 1925 Santa Barbara Earthquake.

But buildings would not disintegrate and topple over in the dramatic and sensational fashion seen in the movie trailers. In a major California earthquake, some older buildings, such as those made of non-ductile reinforced concrete, that werenвЂ™t designed to modern building codes and that havenвЂ™t been retrofitted might collapse and many buildings (even newer ones) would be significantly damaged. Will skyscrapers disintegrate and topple over from very strong shaking? But the title Elsinore + Puente HillsВ doesnвЂ™t evoke fear to the same degree as San Andreas. Instead, the largest loss-causing event in California is one that spans the Elsinore Fault and runs up one of the blind thrusts, like the Compton or Puente Hills faults, that cuts directly below Los Angeles. My colleague Delphine Fitzenz, an earthquake scientist, in her work exploring UCERF3, has found that, ironically, the largest loss-causing event in California isnвЂ™t even on the San Andreas Fault, which passes about 50 km east of Los Angeles. Magnitude 9+ earthquakes on the San Andreas are essentially impossible because the crustal fault zone isnвЂ™t long or deep enough to accumulate and release such enormous levels of energy. To put this in context, an asteroid with a diameter of 1,000 meters is expected to strike the Earth about once every 440,000 years. The consensus among earth scientists is that the largest magnitude events expected on the San Andreas Fault system are around M8.3, forecast in UCERF3 to occur less frequently than about once every 1 million years. Thanks to the recent publication of the third Uniform California Earthquake Rupture ForecastВ (UCERF3), which represents the latest model from the Working Group on California Earthquake Probabilities, an answer is readily available: no. What the movie doesnвЂ™t have is a basis in scientific reality.ДЄre magnitude 9+ earthquakes possible on the San Andreas Fault? As the movie trailersВ made clear, this spectacle is meant to be a blockbuster: death-defying heroics, eye-popping explosions, and a sentimental father-daughter relationship. San Andreas-a Hollywood action-adventure film set in California amid not one, but two magnitude 9+ earthquakes in quick succession and the destruction that follows-was released worldwide today.
