Livermore Lab seismologist to discuss earthquakes today at Las Positas College

Arthur Rodgers talk a feature of college's Science, Engineering series

Arthur Rodgers, a seismologist at Lawrence Livermore National Laboratory, will discuss earthquakes in the San Francisco Bay Area at 6 p.m. Wednesday at Las Positas College.

Rodgers' presentation, which will be free and open to the public, is a feature of the 6th annual Science and Engineering Series sponsored by the college and the Livermore Lab. It will be held in the college's Building 2400, Room 2420.

Rodgers will describe how earthquake faults cut through the San Francisco Bay Area, associated with the boundary between the Pacific and North American tectonic plates. He said earthquakes can't be stopped, "but we can better understand their effects and mitigate the hazard they present."

In his talk Rodgers, will show how computer modeling allows scientists to understand how details of the earthquake rupture and complicated geological structure impact the ground-shaking people experience. He will also show how computer modeling allows them to simulate the effects of a large earthquake before it happens.

Rodgers currently works on Bay Area earthquakes in collaboration with UC Berkeley's Seismological Lab and the U.S. Geological Survey.
