Lori Dengler

Professor Emeritus

My expertise is in geophysics, earthquake and tsunami hazards and hazard reduction.  I am working on a number of projects regionally and within California, nationally, and internationally.  My current projects include a pilot tsunami current monitoring effort in Humboldt Bay and Crescent City, analysis of North Coast tsunami amplification, an number of outreach projects including the Redwood Coast Tsunami Work Group and electronic and print editions of “Living on Shaky Ground”, and promoting earthquake and tsunami education efforts throughout California as the North Coast region representative to the Earthquake Country Alliance.
