California is full of wineries and faults, but only one active winery sits on an active fault.* Last weekend's Wall Street Journal visited the DeRose Winery
and posted photos and a video to go with the story. The winery is in the Cienega Valley in the creeping section
of the San Andreas fault. Continual slow movement on the fault steadily crumples the winery building, making the place a magnet for geologists, wine-loving and otherwise.
There was once another winery in the same situationthe Gallegos winery building straddles the Hayward fault, but only its ruins remain today. The US Geological Survey maintains an instrument package there, and the transit agency BART plans a facility there some day.
*Terry Wright reminds me that Savannah-Chanelle Vineyards in Saratoga occupies land that straddles the San Andreas fault; he says that "the winery building is tweaked by stress." That's not the same thing as being torn apart by aseismic creep, but maybe it still counts.
