San Francisco Bay Area residents were rousted early Monday morning by a 4.0-magnitude earthquake. The 6:49 a.m. temblor, according to the USGS, was located along the Hayward fault in Piedmont at a depth of just over 3 miles.
The Hayward fault was also responsible for the 4.0 Fremont quake that occurred in July. Studies have concluded that a major event along this fault line could result in $32 billion in damages and 20,000 injured or dead.
As for Monday’s quake, “it was relatively shallow,” said Keith Knutson from the USGS. “Near the quake it would have been felt quite intensely.” Still, residents across the East Bay, including those in Oakland, Berkeley and surrounding areas, reported feeling the jolt.
There were no immediate reports of injury or major damage, but the region’s rapid transit system BART did experience subsequent delays.
