Submission: The 318th anniversary of the Cascadia Subduction Zone earthquake
Friday, January 26, 2018 marks the 318th anniversary of the most recent monster earthquake on the Cascadia Subduction Zone (CSZ). In the past 6,000 years or so, these quakes of magnitude 8 or 9 have occurred every 202 years, on average. Only once in that period of time has the interval between quakes exceeded 250 years, so the pressure in the CSZ fault has been growing for a very long time.
