Title: The 150th Anniversary of the Damaging 1868 Hayward Earthquake: Why it Matters
Time and Location: November 13 (Tuesday), 4:00-5:30pm and McCone Hall Room 265, UC Berkeley
Abstract: October 21st marks the 150th anniversary of the damaging 1868 Hayward earthquake. USGS studies of the Hayward Fault reveal that it has produced 12 large earthquakes in the past 2000 years spaced from 100 to 220 years apart. The Hayward Fault is one of the most urbanized faults in the United States. So the expected large Hayward Fault earthquake will impact the entire San Francisco Bay Area. The odds of a damaging M6.7 earthquake in the San Francisco Bay Area in the next 30 years are nearly 3 out of 4. The effects of earthquakes can be mitigated through building codes, retrofits, planning, and training.
