cascadia earthquakes

It’s a good time to remember that the most dangerous earthquake fault on the West Coast is the Cascadia Subduction Zone, not the San Andreas Fault. The Cascadia Subduction Zone is capable of producing a megathrust earthquake with a magnitude of 9.0+ and a resulting tsunami up to 100 feet high. If such a megathrust earthquake occurred today, FEMA estimates that over 10,000 people could die, with tens of billions of dollars in damages. Recent studies suggest that past Cascadia megathrust earthquakes may have also triggered major earthquakes on the northern segment of the San Andreas Fault. The last megathrust earthquake on the Cascadia Subduction Zone occurred in 1700, an event estimated at magnitude 9.0. It generated a tsunami over 50 feet high
