3.4 magnitude earthquake hits east of Pleasant Hill


PLEASANT HILL (KRON) — An earthquake struck near Pleasant Hill Tuesday night.

The magnitude 3.4 magnitude quake hit the area around 7:15 p.m.

Tuesday night’s earthquake followed a 4.5 magnitude earthquake and dozens of aftershocks in the same area Monday night.

BART is telling riders to expect residual delays because of the quake.

Trains are also running at reduced speeds.

Monday’s larger quake was centered in Pleasant Hill and hit around 10:30 p.m.

The 4.5 magnitude quake was the second of two earthquakes Monday night – the preceding one 2.5 in magnitude.

The U.S. Geological Survey says weak shaking was felt in San Francisco, Oakland and San Jose Monday.

Scientists say they don’t expect any major structural damage because of the earthquake.

According to Berkeley seismologists, the 4.5 quake happened on an unnamed fault near the Concord-Green Valley Fault, but not directly on it.

Keith Knudsen, USGS geologist and deputy director of the agency’s Earthquake Science Center, told the Times that the earthquake had a preliminary depth of about 9 miles underneath the surface, fairly deep for this part of the world.

Monday’s quake shook up homes across the East Bay all the way down to the South Bay.
