Engineers began the process of inspecting buildings for damage Sunday after a magnitude-6.0 earthquake struck near Napa, Calif. The quake, which occurred at 3:20 a.m. Sunday on the West Napa Fault just five miles southwest of the city, caused moderate damage to nearby homes and some commercial buildings, but did not lead to any immediate reports of fatalities. Early estimates peg the cost of the earthquake at over $1 billion.
It was the strongest trembler to hit Northern California since the Loma Prieta earthquake struck the San Francisco Bay Area in 1989.
