"Large earthquakes on the San Andreas fault system are a geological inevitability, but individual earthquake occurrence over years to millennia is chaotic. It's mass migrations away from ruined communities. Human decisions such as redlininghave led to many of the inequities in our society, she said. Specifically, the Pacific Plate on the west is moving northwestward associated with the North American Plate on the east, leading to earthquakes along the fault. Visualizations of what a huge earthquake caused by the San Andreas fault may look like have been conveyed in popular culture, such as in the 2015 movie San Andreas. Gas mains would also be damaged, causing subsequent fires to blaze across affected areas. It was believed that this would be most serious in areas that straddle the fault and that $33 billion worth of damage would be done to buildings. This means warning systems could be in place when the fault does inevitably cause a large earthquake. Porter said the shakingwill quickly cut offpowerin many areas.

She is a contributing writer in science for Smithsonian.com and blogs at Wild Things, which appears on Science News. According to theUS Geological Survey, the earthquake, nevertheless, was one of the many caused by episodic displacement along the fault all through its life of approximately 15 to million years. So Erik, let's start by giving us a sense of where the Salton Sea is, how it came to be and why it's so important to seismologists. Seismologists modeled how the ground would shake and then other experts, including engineers and social scientists, used that information to estimate the resulting damage and impacts. He was rumored to have had . An earthquake destroyed their California home days before ] The question: Are we ready?

The Hurricane Pam scenario foretold manyof the devastating consequences of a major hurricane striking New Orleans well before Hurricane Katrina hit the city. And Hill says, now that the Salton Sea is shrinking because of drought and less agricultural runoff, that means there is less pressure on the volatile southern tail of this earthquake fault system. Compared to the previous assessment issued in 2008, UCERF2, the estimated rate of earthquakes around magnitude 6.7, the size of the destructive 1994 Northridge earthquake, has gone down by about 30 percent. And it might be delaying the region's next giant earthquake. Hundreds of thousands more could be left without shelter.
