Overview

• USGS revised the pre-dawn temblor from magnitude 4.6 to 4.3, locating it about 1.2 miles east-southeast of UC Berkeley at roughly 4.8 miles deep near the Hayward–Rodgers Creek Fault.
• Shaking was widely reported from Santa Rosa to Salinas, with no major injuries or widespread structural damage; officials noted localized issues such as shattered windows, items knocked from shelves, and one Berkeley bagel shop closure over a suspected gas-line problem.
• The ShakeAlert/MyShake early-warning system activated before the strongest shaking, sending smartphone alerts across the region.
• Transit and city agencies conducted standard inspections, with BART slowing trains for checks, and the National Tsunami Warning Center reported no tsunami threat.
• USGS aftershock forecasts indicate modest odds of smaller quakes in the coming days and less than a 1% chance of a magnitude 5.0 or larger event, as seismologists highlight ongoing Hayward Fault stress and emphasize preparedness.
