Magnitude 4.3 Earthquake Jolts San Francisco Bay Area Pre-Dawn

A magnitude 4.3 earthquake struck the San Francisco Bay Area just before 3 a.m. Monday, centered near Berkeley on the Hayward Fault, shaking much of the region including Oakland and San Francisco. Initial reports had the magnitude at 4.6, but it was later revised down. Residents across the Bay Area reported feeling sharp jolts that woke them up, with many describing their homes shaking and some unable to go back to sleep. Despite the strong shaking that knocked items off counters and startled pets, there have been no reports of major damage or injuries. The U.S. Geological Survey and local authorities confirmed there is a low likelihood of casualties or economic losses, and the National Tsunami Warning Center stated there is no tsunami threat. The quake occurred near the San Andreas Fault system, a known source of major earthquakes in California.
