Just a little reminder that the Cascadia fault is there.

In the last while, the whole ring of fire has been a little restless.

The Cascadia subduction zone is the third most dangerous seismic hazard for the Puget Sound area, behind the Seattle Faults and the Cascade Volcanoes. Produced a 9.0-ish megathrust earhquake in 1700, but nothing since.

 

Meanwhile, Mount Rainier could produce a lahar that could destroy everything in the Puyallup River valley (including the towns of Enumclaw and Orting, the city of Puyallup, and the Port of Tacoma). And most of the Seattle industrial district is built on landfill from the Denny Regrade, so an earthquake could trigger multiple landslides on the many hills of Seattle.
