t has been 320 years
t has been 320 years since the last major earthquake hit the Cascadia subduction zone. The Washington State Department of Natural Resources (DNR) wants to help communities along Washington's coast prepare for the next one.
On Jan. 26, 1700, an earthquake with an estimated magnitude of 9.0 struck the fault, causing the coastline to drop several feet and producing a tsunami that crashed onto land, leaving sand deposits and drowned forests.
Geological evidence shows these large quakes happen about every 250 years, which means one could happen at any time.
The DNR wants Washingtonians to be able to visualize what another tsunami could do to the state.
The department released a series of tsunami simulation videos that show the estimated height and speed of waves that would strike the southwest Washington coast following a magnitude 9.0 earthquake on the Cascadia subduction zone. Geologists at DNR, home to the Washington Geological Survey, produced the simulations using detailed tsunami models.
