2.8-Magnitude Quake Near Berkeley Before 6 a.m.

A preliminary 2.8-magnitude earthquake struck just before 6 a.m. Thursday about 2 miles (≈3 km) east-southeast of Berkeley at a depth of roughly 5 miles (≈8.4 km), the U.S. Geological Survey reported. There were no immediate reports of injuries or significant damage, though residents reported light to weak shaking on USGS’s “Did You Feel It?” maps. The temblor was one of numerous small quakes and aftershocks following a 4.3-magnitude event early Monday on the Hayward–Rodgers Creek/Hayward Fault that woke many and was felt as far away as Sacramento and Salinas. Monday’s 4.3 quake caused minor damage in some locations, prompted BART track inspections and delays, and was followed by aftershocks including a 3.0 later that day. USGS experts say aftershock sequences are common after a larger quake, could continue for days or weeks, and currently estimate about an 11% chance of another quake of magnitude 3 or greater in the next week.
