Series of earthquakes near SF Zoo shake Bay Area Friday morning
Friday morning, followed by at least two major aftershocks. The initial quake was centered about 6 miles west-northwest of Daly City and 7 miles west of Noe Valley in San Francisco.

It was felt in the KRON4 newsroom and at least as far across the Bay as Alameda. To the south, it was felt down the Peninsula in Pacifica, and in Cupertino in the South Bay.

A subsequent earthquake shocked San Francisco just two hours after the Friday morning quake. This latest earthquake occurred at 9:39 a.m. According to USGS, the quake was a 2.5-magnitude quake.

Both quakes were centered near the San Francisco Zoo, approximately six miles northwest of Daly City.

San Francisco Mayor Daniel Lurie released a statement regarding the earthquake:

“I promised to make the safety of San Franciscans my first priority as mayor, and I am keeping that promise today with this morning’s earthquake. I ordered city government into action immediately this morning, and our first responders have been out across the city ensuring the safety of our residents. We have also been sharing information and giving people the tools to protect themselves and their families in an event like this.”

“I want to assure everyone in San Francisco: We are prepared for these events. As we monitor the impacts of this morning’s event, I am already working with our Police Department, Fire Department, and Department of Emergency Management to ensure we are using best practices to keep our city safe in the event of a natural disaster. And as our hearts are with those across the state and the country dealing with natural disasters right now, we will always make sure San Francisco is ready.”

-SF Mayor Daniel Lurie

A second strong aftershock was felt in San Francisco at around 10:48 a.m. That one registered as 3.0 and was also centered near the SF Zoo.

The San Francisco Zoological Society said the zoo did not sustain any damage after Friday’s earthquakes. In a statement, the group said, “Animal Care Specialists reported no impact to the health and wellness of our animal residents. No structural damage was found after thorough assessments of the grounds and exhibits. The Zoo’s detailed earthquake protocols were executed and it was determined that there was no risk to the safety of animals, staff, and visitors.”

There were no initial reports of damages or injuries as a result of the quake.
