Learn about the History and Relationship of Earthquakes & Volcanoes in Joshua Tree National Park

On Tuesday, December 15th, 2009 at 6:30 p.m. the Palm Springs Public Library, in partnership with the Desert Institute at Joshua Tree National Park, presents Dr. Andrew Barth as he discusses Earthquakes and Volcanoes in Joshua Tree National Park.

Dr. Barth will discuss the historic record of earthquakes in and near Joshua Tree National Park and how it compares to the earthquake record elsewhere in the western United States. The audience will learn how to recognize volcanic rocks and evidence for fault activity typical of this area. Dr. Barth will explain the relationship of earthquakes to volcanoes and faults in southern California and will clarify the Earth’s geologic dynamics of this area.

Andy Barth is a professor of earth sciences at IUPUI (Indiana University – Purdue University Indianapolis) and a visiting professor at Stanford University, with an interest in petrologic processes and the geodynamic evolution of the Cordillera. He received BS and MS degrees in geology from Cal State L.A. and a Ph.D. in earth sciences from the University of Southern California.

The lecture is FREE and open to the public, but seating is limited. The lecture will be presented in The Learning Center at the Library.
