Talk about a coincidence.
On the same day of the Great California ShakeOut, the San Francisco Bay Area experienced a 4.0-magnitude earthquake around 2:45 p.m., according to preliminary reports from the U.S. Geological Survey.
Mayor Ed Lee described the quake as a reminder of the importance of practicing response tactics.
“The question is when, not if, there will be a major earthquake in the San Francisco Bay Area,” Lee said in a statement.
About 8.5 million people in California, including about 1.3 million in the Bay Area, participated in the ShakeOut, an earthquake response drill held Wednesday morning.
The quake’s epicenter was in the East Bay, about 2 miles from Berkeley and 3 miles from Emeryville, according to preliminary data by USGS.
The quake halted Muni and BART. Both stopped trains to check tracks for damage and returned to full speed at about 3:15 p.m.
Muni is now running on time, said spokesman Paul Rose. BART remains delayed, with about 30 percent of its trains 5 minutes behind schedule, said spokesman Jim Allison.
Caltrain spokeswoman Christine Dunn said the earthquake did not disrupt Caltrain service; operators are not required to stop trains and check for problems for earthquakes below 5.0 magnitude.
