A 3.8 magnitude earthquake occurred near San Leandro, as per the United States Geological Survey.
The tremors were felt at 8:30 a.m. and were centered 2.4 miles north of San Leandro, the USGS said.
The initial quake was followed by preliminary 3.0- and 2.8-magnitude aftershocks at about 9:07 a.m, according to the USGS.
Following the initial earthquake, BART temporarily held trains before allowing them to run at reduced speeds while crews completed safety inspections of the tracks.
Normal BART service has since resumed, but the agency said there are major residual delays systemwide.
Fortunately, no damage has been reported yet.
Carla Marinucci, a political analyst and longtime reporter told the NYT, “If you live near the Hayward fault, you always have to be prepared for what they describe as a major quake happening any day. We're overdue,” she said. “In California, we learn to live with this stuff, but it still makes you sweat a little.”
Aftershocks detected
Such tremors are usually aftershocks caused by minor aftershocks, which occurred today a half hours after the first quake.
Aftershocks can occur days, weeks or even years after the first earthquake. These events can be of equal or larger magnitude to the initial earthquake and may also cause damage to some buildings, posing significant threat.
