After spending several posts talking about the "volcanoes" of Los Angeles, let's turn our attention to the other famous metropolis of our fair state: San Francisco and the Bay Area. Most people know of the famous association of earthquakes with the city by the bay, including the 1906 event, and the Loma Prieta quake of 1989. But what are the chances of a volcanic eruption in the Bay Area (note: I am using the term "bay area" loosely)? Are there any volcanoes looming about? And really, wouldn't lava in a Hollywood movie look a lot cooler if it were streaming down Lombard Street?
Quest, Oakland Geology, and About Geology. The Bay Area is his geological beat, and I only pay the occasional visit. Also, don't forget the Interactive Geological Map of California!
