Emergency management officials hope the 5.6 temblor — and its 3.7 aftershock — that rattled the Bay Area Tuesday night and Wednesday afternoon also shook its residents into action.
Wednesday’s large aftershock at 4:54 p.m. was felt as far north as Redwood City and as far south as Gilroy. The moderate quake at 8:54 p.m. Tuesday night was felt north of Santa Rosa and south of King City, said U.S. Geological Survey geophysicist Jack Boatwright.
Tuesday’s quake, on a fairly active section of the Calaveras fault, caused minor damage but no injuries, Boatwright said. At the Reid-Hillview airport in San Jose, glass was broken in the control tower. Alum Rock’s James Lick High School also experienced broken windows, Boatwright said. The earthquakes, centered in the hills east of San Jose, are reminders for Bay Area residents to check their quake-readiness, local government officials said.
Within five seconds of a major quake, residents should duck under sturdy structures, cover their heads and remain calm. Within five minutes, they should tune a battery-operated radio to KCBS (740 AM) and see if anyone needs help. Flashlights should be used in place of candles, the San Mateo County Office of Emergency Services said Wednesday. Emergency officials also suggest residents have enough food, water and medicine to be self-reliant for at least five days and form a reunion plan with their family.
