#NapaQuake
A 6.0 magnitude earthquake shook north of San Francisco early on Sunday, seriously injuring two people, igniting fires and buckling roads in the scenic Napa valley wine region.
The quake struck near American Canyon some 40 miles (64 kilometres) northeast of San Francisco, the USGS said. It roused people from sleep as far away as San Francisco, and was felt as far east as Sacramento and as far south as Santa Cruz.
Most damage appeared centered around Napa, a famous wine-producing region and a major tourist destination in northern California.
Brick facades gave way in the historic section of downtown Napa, and bricks fell off a second floor corner of the courthouse, which showed cracks. On the main street, masonry collapsed onto a car.
The City’s website said there were some 50 gas line breaks, 30 water line breaks and many broken windows and buildings with interior damage.
The quake knocked out power to about 40,000 homes and businesses in Napa and neighboring cities of Sonoma, St. Helena and Santa Rosa, according to the website for Pacific Gas & Electric.
The California Highway Patrol closed several off-ramps to highways and at least two roads in Napa Valley because of “significant roadway damage”. Drivers were cautioned to be careful at an intersection of two state roads in Napa Valley. “Cracks in road may cause flat tires,” it said on its Twitter account.
