"" At 3:20 a.m. Pacific time on Sunday, an
earthquake with a magnitude of 6.0 hit the
San Francisco Bay Area.
The USGS reports that it occurred 6.7 miles
below the surface, with an epicenter just
south of Napa and about 30 miles
northeast of San Francisco. This is the
strongest earthquake felt by the region in
25 years, since the 1989 Loma Prieta
quake , which had a magnitude of 6.9.
There have been no deaths reported so far,
but 87 people are being treated for injuries
at a Napa hospital, and three are in
critical condition — including a child
struck by fragments of a collapsing
chimney.
There are also numerous damaged
buildings and roads in and around Napa,
including a damaged highway foundation
near the city of Vallejo.""
