The Cascadia Subduction Zone is a 600-mile fault that runs from northern California up to British Columbia and is about 70-100 miles off the Pacific coast shoreline. There have been 41 earthquakes in the last 10,000 years within this fault that have occurred as few as 190 years or as much as 1200 years apart.
In what was long held as a dormant fault zone, the Garlock fault had two significant quakes in July 2019, a 6-4 and 7.1. Experts are wondering what this east-west fault zone brings to the area where more than four other faults also connect to Garlock, which connects to the San Andreas Fault line north of Los Angeles. Could this mean more activity in the near future as stress builds on Garlock?
This week Drew and I talk about a really unique “mega-storm” phenomena to California and the Central Valley.
