Magnitude 2.7 Earthquake Strikes Near East Bay Refineries
CROCKETT, Calif. (CBS SF ) — The U.S. Geological Survey says a magnitude 2.7 earthquake has struck in the north East Bay.
The quake struck at 11:32 a.m. PST Tuesday 1 mile southeast of Crockett near several refineries between the Concord and North Hayward Faults.
The Concord Fault is causing concern among Bay Area planners who worry that its 11-mile fracture zone is capable of producing a catastrophic earthquake that would impact regional and statewide fuel distribution.
A December study by the Association of Bay Area Governments found aside from the San Andreas and Hayward faults, all but two of the five Bay Area refineries, which are responsible for 40 percent of the state's total barrels of crude in 2012, are within a couple miles of the Concord Fault.
There are no immediate reports of damage.
