SAN FRANCISCO (KRON) — Bay Area residents awoke to a strong jolt Monday morning after a magnitude-4.0 earthquake struck in the East Bay, according to the United States Geological Survey. The intensity of the jolt was downgraded from a magnitude-4.2.
The USGS said it happened at 6:49 a.m. Some KRON 4 News viewers are reporting minor property damage, but there have no reports of major structural damage or tsunami warnings as a result of the quake.
According to the USGS, the quake was centered about one mile north of Piedmont, three miles northeast of Oakland.
Several KRON 4 News viewers emailed, called, and messaged the station on social media to report feeling the jolt throughout the Bay Area, including Napa, Fairfield, Pacifica, and parts of the Silicon Valley.
“Felt it quite strong here in the Oakland Hills! Strong rumble. I’m about 5 miles or closer to Piedmont. This one scared me; I felt slightly off balance immediately after,” wrote Susheela.
Some people wrote in to say they slept through the early morning shake or that they didn’t feel it, but many others described the quake as “violent,” “scary,” and “I thought it was the big one.”
“I had just got up and was sitting on the toilet and felt that quake!! At first I thought the lady upstairs had gotten violent, and quickly realized it was a quake! I flew off the can,it was a very hard jolt and a shake!! Freaked me out, and I immediately put on KRON . I live in Walnut Creek. Scary!!,” wrote Jeann.
“I sure did feel the earthquake here in Fairfield….. It felt like something jolted the house with a lot of power, but it was a very quick. I didn’t feel any rocking like other people reported. It was more like a big push,” said Maggie.
Misty, an employee at Children’s Research Hospital in Oakland, said the “shake was really violent, but happened very quick. You could hear everything just shake.”
We live in So Berkeley, above the Claremont Hotel, really felt the earthquake, was a big jolt followed by shaking. Several objects fell over and a crack in the plaster wall got bigger. It lasted long enough to jump in a doorway. We have a 4 level,house and my daughter on the bottom level texted! Me to say she felt it and was ok. My two other children on my level slept right through it and are still sleeping! The pets (a parrot and 2 dogs) were surprisingly quiet.
Husband off to work via Bart, hoping for no damage or long delays.
Thanks for the great coverage.
Oakland resident Elizabeth Weintraub said she had just woken up and was nursing her baby in a rocking chair when the quake struck. “It was the strongest earthquake I’ve felt since living in the Bay Area for 8 years. It was short but intense. When it started, I thought it was the big one. I was so scared. I heard silverware and dishes rattling in the kitchen down the hall but nothing seems to have fallen,” she said.
The USGS reports that the earthquake struck at the The Hayward Fault, a mostly right-lateral, strike-slip fault. The Hayward Fault runs from San Pablo Bay in the north to Fremont in the south, passing through the cities of Berkeley, Oakland, Hayward, and Fremont.
