The San Andreas Movie contains a lot of information about plate tectonics that we learned or discussed about in class. In the beginning of the movie, it mentions how they use graphs in order to predict when the next one might happen and where. When they showed the graphs in the movie, I was able to identify where the P and S waves started which indicates how strong the earthquake will be and allows them to measure the duration of the earthquake. They also mentioned how overtime the plates are moving and shifting which can start to move the land as well. This part of the movie reminded me of when we started talking about Pangea and the Continental Drift. The land can move due to the plate tectonics shifting and they will continue to shift over time as well. When they started looking into where the San Andres Fault is at, they looked at the two plate tectonics in California. We know that in California the San Andres fault contains the Pacific plate and the North American plate. These plates create a transform boundary that go alongside the bay of California and pass through as what we know as the Cajon Pass. These plates are rubbing against each other and can create stress which later on creates an earthquake along or near the plate. After an earthquake occurs, aftershocks can happen which can be shorter than the original earthquake.
