The cleanup continues Monday after a massive 6.0 earthquake hit the Napa Valley area, northeast of San Francisco around 3:20 a.m. PDT Sunday. Since 1989, the overnight quake is the largest in California in the last 25 years, according to the U.S. Geological Survey. Residents told KGO-TV the earthquake sounded like a big crash as it rattled and swayed buildings, homes, toppled items onto floors, crushed cars in garages and cracked up roads in northern California’s wine country. Fires also erupted from broken gas lines. More than 200 people have been treated at Queen of the Valley Medical Center since Sunday. Earthquake scientists expect more and possibly stronger aftershocks this week. Governor Jerry Brown declared a state of emergency. The damage was estimated to be 1.o billion dollars. Local officials told CNN the earthquake has drained them of resources and outside help is needed. Many damaged buildings and homes were tagged as unsafe.
