Scientists Found Evidence of a Massive M9.0 West Coast Earthquake

Scientists drilling beneath the Pacific Ocean off Oregon uncovered unexpected evidence hidden inside ancient sediment—evidence that could change how researchers understand the earthquake history of the U.S. West Coast.

In this DiscoverTube documentary, we investigate new research into the Cascadia Subduction Zone, ancient earthquake deposits, the northern San Andreas Fault, and evidence suggesting some major earthquakes may have occurred closer together in time than previously recognized.

This discovery does not mean an M9.0 earthquake is imminent. Instead, it gives scientists new clues about how enormous fault systems along the West Coast may have behaved over thousands of years.
