The Cascadia Subduction Zone - Latest Research
The latest exciting scientific news about the Cascadia Subduction Zone (first discovered in 2001, and confirmed in 2002) is the observation of silent, aseismic (no shaking) slip events on the CSZ. The silent slip events have occurred regularly, every 14 months, since at least 1998. The largest of these events involved a 60-kilometer-by-300-km area about 30 km or more beneath Vancouver Island and Puget Sound that slipped about 30 mm over a period of 12 days or so.
