A magnitude 3.8 earthquake struck near San Leandro on Thursday morning, according to the U.S. Geological Survey. The earthquake occurred at 8:30 am. Its epicenter was about 2.4 miles north of San Leandro and about 5 miles from Oakland and Alameda, USGS data shows. The earthquake was initially measured at 4.1, but was revised downwards shortly after. Two aftershocks struck near San Leandro shortly after 9 am. A magnitude 3.0 earthquake occurred at 9:07 a.m., approximately 1.9 miles northeast of the city at a depth of 3.1 miles. Four seconds later, a magnitude 2.8 earthquake struck about 1.9 miles north of San Leandro at a depth of about 3.9 miles. BART temporarily slowed service while crews inspected the tracks after the earthquake. The agency said inspections have been completed and normal service has resumed, although passengers could experience residual delays of up to 20 minutes throughout the system. The earthquakes originated about 3.2 miles below the surface near the Hayward Fault, which runs through much of the East Bay from San Pablo Bay to Fremont. The fault is moving slowly at about 5 millimeters per year, according to the USGS. The Hayward Fault last produced a major earthquake in 1868, when a powerful tremor killed 30 people and caused widespread damage throughout the Bay Area. This breaking news has been updated.
