Update | An earthquake struck the Bay Area early Thursday morning along a fault line that U.S. Geological Survey scientists have called a “tectonic time bomb.” The earthquake hit near Berkeley, California, as a magnitude 4.4. The damage is expected to be minimal, but it occurred along the Hayward fault—one of the seven fault zones in the Bay Area, according to the USGS.
The earthquake shook for about five to 10 seconds, reported the Los Angeles Times, and an estimated 9.8 million people felt the quake. The depth was about 8 miles, which is relatively shallow. Some earthquakes can be more than 350 miles deep in countries such as Fiji, according to USGS duty seismologist Robert Sanders.
