Rose Canyon Fault

Professor Thomas Rockwell

San Diego’s Rose Canyon fault produces powerful earthquakes more frequently than once believed, but a major temblor is not imminent, according to researchers at San Diego State University. SDSU scientists who studied the part of the fault located in the Old Town neighborhood determined that the system — which before 1990 was thought to be inactive — generates a magnitude 6.5 to 6.8 earthquake about once every 700 years. This lecture will discuss the seismological history of San Diego and the results of the recent study.

Instructor: Thomas Rockwell is Professor of Geological Sciences at San Diego State University. An internationally renowned paleoseismologist and structural geologist, he is an expert on the tectonics and earthquake hazards of southern California and Baja California. He has conducted extensive trenching programs to date earthquakes on faults in the western U.S., South and Central America, the Middle East, and Asia. He received his PhD from UC Santa Barbara.
