The Cascadia subduction zone, where the Juan de Fuca plate subducts beneath North America, presents one of the greatest earthquake hazards in the U.S. Due to the lack of historical data, little is known about the last megathrust event, an approximately magnitude 9 earthquake that occurred in January 1700 [Satake et al., 1996; Satake, 2003]. Recent subduction zone fault earthquakes around the world underscore the similar challenges we will face when Our research cruise is happening along the continental margin behind the subduction zone itself. The CSZ is different than most subduction zones in that it is "locked."
