Richard Allen, professor and director of the UC Berkeley Seismological Laboratory, discusses the lessons learned from the 1989 Loma Prieta earthquake which was centered on a section of the San Andreas Fault near Santa Cruz. It shook Northern California at 5:04 p.m., causing 63 deaths, several thousand injuries, and $6 billion in property damage, including the collapse of a section of the upper deck of the Bay Bridge, a section of the Interstate 880 freeway in Oakland, and many residential homes in San Francisco’s Marina District.
