Northern California rocked by magnitude 6.0 earthquake

A magnitude 6.0 earthquake hit Northern California near Napa Valley Sunday, injuring 89 — 3 critically — and causing extensive damage, including fires sparked by burst gas lines, in the largest tremor to rock the Bay Area since the magnitude 6.9 Loma Prieta quake in 1989.

Leslie Gordon of the U.S. Geological Survey says the tremor struck just before 3:30 a.m. Sunday local time, about 10 miles northwest of American Canyon, which is about 6 miles southwest of Napa.
