2017 Lawson Lecture: The Future of Past Earthquakes: Insights into Earth Behavior from Earthquake Geology and Paleoseismology

Lecture | April 26 | 4:30-6:30 p.m. | International House, Chevron Auditorium

 Dr. David P. Schwartz, United States Geological Survey

 Berkeley Seismological Laboratory

The field of earthquake geology, which includes paleoseismology, provides approaches for quantifying the longer term behavior of active structures and active regions in time and space. Since the mid-1960s, when trenching was first used for simple fault location primarily in California, investigations of the rupture behavior of seismogenic structures have spread globally to all tectonic settings including subduction zones. Using improved and new techniques for dating geologic deposits and geomorphic surfaces, incorporating high resolution ground-based and satellite imagery for measuring coseismic surface and longer-term displacements, and investigating sites with long records of earthquake occurrence and event slip, earthquake geologic studies have expanded our four dimensional understanding of active earthquake systems and provided fundamental data for seismic hazard analysis. The Lawson Lecture will discuss these concepts with worldwide examples and special emphasis on the past and future behavior of faults in the San Francisco Bay Region.
