“Ready for the Next Big Bay Area Earthquake?” will be seismologist Tom Brocher’s topic at the US Geological Survey on Thursday, Sept. 25, at 7 p.m. in Building 3, at 345 Middlefield Road in Menlo Park.
The 1989 Loma Prieta Earthquake was not the “big one” that Bay Area residents have been expecting. But a repeat of the earthquake that broke the Hayward Fault in the East Bay 140 years ago, on Oct. 21, 1868, could well be the “big one,” Dr. Brocher warns.
Unlike the San Andreas Fault on the Peninsula, the Hayward Fault is the most urbanized fault in the Bay Area. It crosses major freeways, water lines, sewer lines, rail lines, and BART. Estimates say a large earthquake there could impact more than five million people, with $1.5 trillion in property damage.
