Blue Dot 17: Cascadia Rising

FEMA

Another Big One is coming. This one won't be in Southern California though — it's in the Pacific Northwest. The Cascadia Subduction Zone is off the Pacific coast, and pressure has been building for a very long time. When the fault slips and the megathrust earthquake happens, it will create a massive tsunami and many powerful aftershocks. 

We'll hear again from Ken Hudnut from the US Geological Survey, this time about what will happen with this quake hits. We also speak with Kristin Ludwig, a staff scientist at the USGS, about the Cascadia Rising interagency exercises that just happened to test the preparedness of reactive agencies.
