ABC7 Eyewitness News viewers from across the Bay Area felt the shaking and were woken up. People reportedly felt it in Richmond, Mountain View, Hayward, Pacheco, Oakland and San Francisco.

There have been no aftershocks, but USGS seismologist Robert de Groot told ABC7 Eyewitness News that there’s about a 40% chance for a magnitude 3.0 quake or larger within the next week.

“There are on the order of 50 earthquakes a day in California. These magnitude earthquakes don’t happen very frequently, but they happen frequently enough that there are these reminders that we do live in earthquake country,” de Groot said.

Items in one aisle of the Boulder Creek Drug Store fell off from the shaking and were seen on the floor. No other stores in the area appear to have any items that fell, and there have been no reports of damage.

Jenna Lupertino, the owner of Jenna Sue’s Cafe across the street from the drug store, lives even closer to the epicenter than her business. She says the quake woke her up and gave her a scare.

“It was super loud, I woke up, jumped out of bed, ran to my daughter’s room and then saw that she was fine and nothing really fell over in my house except for a mirror,” Lupertino said. “And then I thought about the syrups here and I thought ‘Oh my gosh, they’re going to be all over the floor’ and then that inner shaking feeling that doesn’t go away for probably like 15-20 minutes waiting for that next aftershock.”
