Everybody knows the Big One is coming. Depending on where it strikes, it’ll be felt from Oregon to Baja California as well as Nevada and Arizona. Thousands may die. Millions will lose homes. The Big One is a California problem, but it won’t send a tsunami crashing around the Pacific

June was off to a bumpy start in the Bay Area. Three separate tremors happened in the early morning hours of Sunday, June 3rd. The first at 1:40 AM rattled the leeward side of the Berkeley Hills two miles north of Orinda. It was a M2.2, barely perceptible but to

A Big Change to This Year’s Voter Guide We’ve been doing voter guides for a really long time. I’m pretty sure we put our first one out in like 2010 or something. And I know that thousands of you rely on our voter guides to help you make decision. But

Turkey’s tectonic predicament, responsible for the massive quake that struck Kahramanmaras at 4:17 Monday morning, looks awfully familiar.  The tectonic situation in Turkey nearly mirrors California’s. Similar mechanics are at work here. Our dominant faults shove landmasses past one another in opposing directions, much like theirs. The major difference is,

A M2.9 earthquake struck just south of Half Moon Bay shortly before 9:30 last night. Residents of San Mateo and Redwood City also reported feeling the jolt. It happened at a depth of 10.4 kilometers, or 6.4 miles, beneath the rugged coastline within the San Gregorio Fault Zone. The San

Tuesday’s M5.1 was the strongest to strike the Bay Area since the South Napa earthquake in 2014. That event, a M6.0, resulted in one death and dozens of injuries. The quake occurred on the Calaveras Fault, known among geologists as a “creeping fault.” It usually moves aseismically, or without producing

Sunday night’s earthquake was unremarkable by California standards. For some, the M2.9 tremor was their very first seismic experience. A burp of the notorious Hayward Fault, it struck near the mouth of the Caldecott Tunnel directly beneath Highway 24, where it dams Lake Temescal. North Oakland’s Rockridge and Piedmont neighborhoods,

Earthquakes are as much a part of Bay Area life as fog, hills and cable cars. But for some reason, other than learning about the wreckage of past quakes, the average Bay Area resident doesn’t spend much time discussing how a large earthquake would effect modern Bay Area infrastructure. The Hayward

Mr. Worry: the San Andreas Fault The title of Mr. Worry goes to the San Andreas Fault, since he worries the whole state of California. The San Andreas is arguably the world’s most famous fault. It leveled Los Angeles with a fictional M9.9 in 1974’s cleverly-titled Earthquake. Casualties included characters
