Marine Seismic Imaging and the Cascadia Subduction Zone

Off the Pacific Northwest coast, the 680-mile-long Cascadia subduction zone has produced giant earthquakes and tsunamis similar to the one that ravaged Japan last year. These earthquakes, the most recent in 1700, result from stresses that slowly accumulate along a deep fault zone as the oceanic Juan de Fuca plate grinds toward and descends beneath North America. Listen to Marine Geophysicist Suzanne M. Carbotte discuss the Cascadia subduction zone, her recent expedition aboard Columbia’s research vessel the R/V Langseth and the advanced marine seismic imaging used to study the Juan de Fuca plate prior to its descent.

This event will be held at PicNic Cafe (2665 Broadway btw. 101st & 102nd Sts.), 212-222-8222.
