4/17/20 Physical Geology Movie Disasters Movie Disaster Extra Credit Assignment 1.This film that I chose to watch portrays a real account of events that’ll occur if “the big one” does happens. For years, scientist have predicted that the San Andreas fault will trigger one of the most catastrophic earthquakes that will ever hit California. In this film, Dwayne Johnson plays a search-and-rescue helicopter pilot in San Andreas, who sought out to rescue his daughter following a devastating, magnitude 9 earthquake. 2.Five scientific facts include: Earthquake Swarm. The beginning of the movie describes an “earthquake swarm” in Nevada and the occurrence of hundreds of smaller earthquakes across a period of a few days. This is a very real phenomenon, even though not necessarily a reason for panic. Ongoing Aftershocks. Throughout the movie, the stars are rocked by a regular series of aftershocks. Aftershocks are an often-overlooked factor of how frightening an earthquake can be. The rooftop pool scene . Among the chaos during the first big earthquake of the movie, there is a brief camera cut to a rooftop pool, which has developed a massive and unified swaying wave. The rooftop pool created a kind of wave that is known as a seiche. Fire Following . The movie correctly stresses that an earthquake will likely cause gas pipes to break and fires to break out. This has potential for a major inferno, as was the case in the 1906 San Francisco earthquake. The science of the tsunami. Before a massive tsunami overtakes San Francisco, the water in the bay withdraws seeing that makes it scary not knowing what’s coming next. Though the tsunami itself is inaccurate, the fact that the water withdrew before it hit was spot-on. While this may happen, it is not guaranteed to happen. 3.) Five false statements/ scientific inaccuracy: The Magnitude 9.6 Earthquake. The magnitude potential for the San Andreas Fault is drastically overstated in the movie. Such an earthquake would require around 12,000 years of build up since the last earthquake; in reality, there has only been one like that since 1960 near Valdivia, in southern Chile. The “One Wave” Tsunami. A tsunami is made up of multiple barrage waves and is characterized by a series of incoming and receding displacements of water. Proper caution, following an initial surge should always be exercised when a tsunami scenario happens. The Earth Opening Up Along the San Andreas. Earthquakes are produced by rocks being pushed together. The two sides of the San Andreas Fault would slide past each other and never pull apart otherwise no earth would happen. The amount of damage and deaths. The death and destruction portrayed in the film is quite negative, because it inspires fatalism and promotes a sense of helplessness. The film undermines seismic design. New buildings are designed to be strong against earthquakes. They would be heavily damaged, but there would be time to get out of them before they collapse. To see

buildings crumbling in San Andreas suggests that engineers are unable to design against these sorts of events – this is simply not true. Engineer can’t protect against every sort of damage, but with proper buildings and strong structure, we can ensure that buildings stand up in a way that allows people to escape. The earthquake predictions. Even though the movie was only about 2 hours long, it moved quick. It depicted the image that earthquakes can happen at a drop of a dime without much warning. The officials weren’t informed in time, which lead to many causalities. Thus, this is false due to all the new available technological advances that can detect very minor trembles under earth’s surface.
