Earthquake Hazards in Western Washington The mega-thrust at the coast Shallow thrusts in the crust of Puget Sound Normal faulting in the subducted Juan de Fuca Plate Which should you worry about?

Earthquake Hazards in Western Washington The mega-thrust at the coast Shallow thrusts in the crust of Puget Sound Normal faulting in the subducted Juan de Fuca Plate There have been 3 events in the last 60 years: 1949, 1965 and 2001. There WILL be more in YOUR lifetime. The last one caused $1,000,000,000 in losses that were largely preventable.
