EES 0836 San Andreas Movie Questions Disasters: Geology vs. Hollywood Introduction In the aftermath of a massive earthquake in California, a rescue-chopper pilot makes a dangerous journey with his ex-wife across the state in order to rescue his daughter . - imdb.com Learning Objectives Critically assess the portrayal of science, earthquake behavior, and emergency response along the San Andreas fault system in the movie San Andreas (2015). (4, 5, a) Part 1: Watch the movie As you are watching the video clips, look for the answers to the following questions . 1. It’s unclear if an earthquake caused the landslide in the opening scene, but in real life, can earthquakes cause mass wasting events? How can this happen? Yes, an earthquake can cause mass wasting events. It can happen because the ground after an earthquake can be unstable, thus causing events like landslides. 2. Is Dr. Hayes ’s prediction about the “next big one” different from how earthquakes are predicted today? No scientists are not able to accurately predict earthquakes. Scientists use two precursors: Pattern and frequency of earthquakes like foreshocks and Deformation in the ground surfaces like change in land elevation, tiltmeters, and Radon gas levels. 3. If you “discovered” that there are active fault lines in Nevada, does it seem plausible that you would be able to use them to help you predict earthquakes? What is the likely reason why they are recording earthquakes in this area? (Feel free to review lecture notes.) It would not happen like in the movie in real life because engineering requirements have gone up which when someone is building a place, the building/ structures will withstand an earthquake with minor damages than the ones shown in the movie. 4. Is evacuating a building the best course of action during an earthquake? If not, what is? No, once inside a building, you should look for cover underneath a sturdy table or something similar that would protect you from falling objects. 5. Whoa, that’s a lot of destruction! You can clearly see seismic waves propagating across the landscape. What type of wave do you think this is? Explain your reasoning. Surface waves, as they could be seen ripping through the landscape.
EES 0836 6. Dr. Hayes explains on the news that San Francisco will “get hit again, with a 9.5M event or higher. It will be so big that people on the east coast will feel it.” What is wrong with this statement? It's improbable that people on the east coast would not feel an earthquake that occurs on the west coast regardless of magnitude. As the wave travels to the different types of ground composition, waves will die down, and the denser ground absorbs the shock. 7. The Rock and his wife are warned that the road is out ahead. They come to a place where the earth has been displaced. There are two types of faults here. Name one of them and explain your reasoning. ( If you can name them both, that would be awesome! ) Strike-slip fault, due to the movement of the two plates against one another and the release of built up strain. 8. How does the Rock know that a tsunami is coming? What is this part of the wave actually called? He knows the tsunami is coming because he sees that the water is starting to regress quickly. This part of the wave is called the run-up. 9. What is wrong with how the tsunami wave is depicted? The tsunami is depicted wrong because the vast part of the San Andrea fault is on land. Thus, it makes it unlikely that the wave could be of the size/height it was. 10. Why would you NOT see a local tsunami occur in the San Francisco area? You wouldn t see a local tsunami in the San Francisco area because the San Andrea faults are vertical, and you need a horizontal fault movement for a tsunami to happen 11. As the parents are looking for their daughter, the water is no longer moving inland. Should our heroes be concerned about anything else? Why/why not? Yes, other tsunami waves could come after the first one that can be minutes to hours apart. However, if that was the last wave, they should still be concerned about the water dragging them back to the ocean. The water tends to recede to where it came from. 12. The aerial shot at the end?!?! Really again with this misconception? What happened? Why is this not valid? The aerial shot at the end of the movie does not depict the true destruction of the natural events that took place.
