According to the U.S. Geological Survey, light shaking was recorded in Berkeley, Oakland, and San Francisco, as well as in Albany, Alameda, San Leandro, Piedmont, Orinda, Lafayette, Walnut Creek, and Richmond. Shaking of this intensity, measured on the Modified Mercalli Intensity Scale, is typically strong enough to rattle windows and dishes, rock parked cars, and feel similar to a heavy truck hitting a building.
Several residents reported being woken by the tremor. One described the shaking as lasting 10 to 12 seconds, while a caller from the Oakland Hills told KCBS-AM radio that dishes had fallen from shelves and shattered on the floor. The quake was also felt near San Francisco International Airport, where it coincided with an alert from the MyShake earthquake early warning app.
Despite its wide reach, the earthquake did not cause significant damage. The USGS noted there is a 4% chance of another earthquake of magnitude 4 or greater occurring in the next week. The chance of a stronger aftershock reaching magnitude 5 or higher remains under 1%, making the likelihood of a damaging follow-up quake relatively low.
For now, the quake serves as a reminder of the region’s seismic activity and the importance of preparedness. Residents are encouraged to secure heavy items in their homes and remain alert to potential aftershocks.
