Earthquake rocks Hayward Fault; Jolts East Bay residents awake

OAKLAND, Calif.  (KTVU) -- A earthquake of a 4.0 magnitude struck near the Caldecott Tunnel in the Oakland hills on the Hayward Fault early Monday, jolting residents awake from Martinez to San Francisco and shaking items from shelves.

According to the U.S. Geological Survey, the quake struck at 6:48 a.m., was centered in Piedmont and had a depth of 3.3 miles. Several small aftershocks were measured followed with the largest at 2.3. 

“It was relatively shallow,” said Keith Knutson from the USGS. “Near the quake it would have been felt quite intensely.”

However, Knutson who was at the USGS headquarters in Menlo Park, said he did not feel the quake.

BART officials shutdown the system to make sure the tracks were not impacted by the quake. No damage was found and trains were quickly returned to a normal schedule.

While some items were shaken from shelves, there was no significant damage reported.

On KTVU’s Facebook page, residents from across the East Bay reported feeling the jolt.

In Alameda, Tim Erwin’s kitchen was rocking as he got ready to the day.

“Strong in Alameda,” he wrote.  “Dishes were rattling.”

Sarah Shear O’Sullivan lives near the epicenter in the Temescal area of Oakland.

“It packed a powerful punch--quite the jolt, she wrote. “ House was making all kinds of noise.”

Across the Bay in San Francisco, residents in the Western Addition felt the jolt.

“Shook here in Western Addition for like 25 seconds,” Jashlyn Canon Girard wrote. “ Felt like a 5.”

In Walnut Creek, Doretta Kennedy wrote her Walnut Creek  apartment building shook.

“Yes it was strong here in Walnut Creek,” she wrote.  “My whole entire apartment building shook.  Still shaking.”
