Twin Quakes Jolt SF, Berkeley

Two earthquakes shook the San Francisco Bay Area yesterday, the same day that California held its annual earthquake preparedness drill and nearly 22 years to the day after a quake killed 63 people in northern California. A 4.0-magnitude quake hit the Bay Area, centered near Berkeley, at 2:30 in the afternoon, and a 3.8-magnitude temblor followed some six hours later, AP reports. No damage or injuries were reported from either quake. The stronger quake was a "sharp little earthquake" that had a "very nice impulsive character," a United States Geological Survey seismologist says. (More earthquake stories.)
