Two small earthquakes rattled California’s South Bay on Tuesday afternoon, according to the U.S. Geological Survey. A preliminary magnitude-3.0 temblor struck at 2:16 p.m. local time about five miles west of Cupertino at a depth of roughly six kilometers. Roughly 100 minutes later, a magnitude-2.6 aftershock hit the same area. USGS data indicate the quakes produced light shaking that was felt in nearby communities including Sunnyvale, Los Altos and parts of San Jose. Local authorities had not received reports of damage or injuries as of early evening. The pair of quakes are typical of low-level seismic activity along the San Andreas fault system that runs beneath the region. Seismologists advise residents to review emergency plans and supplies, noting that even minor events serve as reminders of the Bay Area’s earthquake risk.
