In the Pacific Northwest of the United States, the Juan de Fuca plate is being subducted under the North American Plate at the Cascadia Subduction Zone. The lecture will discuss the hazards of and the preparedness for ground shaking, liquefaction, landslides, and tsunamis along the subduction zone. What are the differences of recurrence intervals for large earthquakes on the northern and southern margins?
Much of the region was not thought to be an earthquake region so earthquake building standards are fairly recent. How does the chance of crustal, plate, and subduction quakes affect building codes, emergency preparedness, siting of critical facilities, building of bridges, and transportation corridors in the region? What have we learned from recent subduction quakes around the world that can be applied to the Pacific Northwest? What can the region expect after a large quake?
