shaken by strongest
quake in 13 years
SAN FRANCISCO (AP)-Northern
California's strongest earthquake in 13
years rocked a 350-mile wedge of the
state in two sweeps of at least 10 secor-
ds each yesterday, toppling light poles,
knocking out power, and shaking
skyscrapers. There were no immediate
reports of serious injuries, and damage
apparently was minor.
The tremor, which registered 5.9 on
the Richter scale, hit at 10:06 a.m. PDT
and was the third quake in less than
four months to be felt throughout the
San Francisco Bay area.
"It knocked me right out of my
chair," said Jim Iverson, a California
Highway Patrol official in Salinas, 20
miles southwest of the temblor's recor-
ded epicenter. "At first it was a
buckling motion and then it felt like we
were rowing. I've never seen a hallway
twisting like that."

measured the quake and plotted its
epicenter at 18 miles north of Hollister
on the Calaveras Fault.
The quake was felt well into Southern
California, with vibrations recorded as
far south as Encino, 15 miles north of
Los Angeles, said Nate Hutton, a
seismologist with the California In-
situte of Technology.

shake apart," said Barry Breckling,
head ranger at the Henry W. Coe State

more than 10 seconds."
A FELTON woman was taken to a
Santa Cruz County hospital with a
broken leg after she was knocked to the
floor of her home, authorities said. The
leg had just been removed from a cast a
week earlier for a similar break.

taken to hospitals, most with heart at-
