On March 11, 2011, a devastating magnitude-9 earthquake struck off the coast of Tohoku, Japan, where the Pacific Plate dives beneath the Okhotsk Plate. On January 26^th, 1700, the West Coast of the United States experienced a similar tsunami-generating megathrust earthquake. An earthquake like this will strike the Cascadia subduction zone again. How can we protect ourselves?

Residents of California, Oregon and Washington now have an earthquake early warning tool—the ShakeAlert© system, operated by the United States Geological Survey.
