People from San Jose to Santa Rosa said they felt the East Bay-centered quake, according to the USGS Community Internet Intensity Map. Those near the epicenter described the shaking as “light” to “weak.”

 

The earthquake briefly interrupted the San Francisco Giants game Monday night. NBC cameras picked up the shaking moments before the Giants’ Chris Stratton threw a pitch.

Glen Park resident Roberta Guise was watching the Golden State Warriors play the Houston Rockets in Game 1 of the NBA Finals when she felt a “single thump.”

 

Just before 7:30 p.m., BART reported a 10-minute system wide delay due to the earthquake.

The City of Oakland issued an AC Alert more than an hour after the earthquake subsided. No damage or injuries were reported to the city. Officials warned residents to remain alert to possible aftershocks.

Aftershocks can occur following a quake of magnitude 3.5. They are generally considered to be within a “fault length” of the original quake, meaning aftershocks could occur within 20 miles for a 20-mile-long fault. The Hayward Fault is more than 70 miles long.
