Aftershocks Don't Take A Holiday

A series of earthquakes Thursday shook the Paso Robles area, where a magnitude-6.5 quake earlier this week killed two people, flattened historic buildings and caused $100 million in damage.

The largest in the series of earthquakes had a magnitude of 4.4 and struck about 10 miles west-southwest of Paso Robles around 3:50 a.m., according to a preliminary report from the U.S. Geological Survey. Several of the aftershocks had magnitudes of 3.0 or higher.

Monday's temblor, centered near San Simeon, 25 miles west of Paso Robles, rumbled through the San Luis Obispo County countryside and beyond, causing the worst destruction in Paso Robles and scattered damage in other towns. Two women were found dead under the rubble after Paso Robles' 19th century clock tower building collapsed.

The earthquake was felt as far away as Los Angeles and San Francisco.

The USGS said after Monday's earthquake that aftershocks were likely to continue along the fault system for months and that there was a 90 percent probability that aftershocks of 5.0 magnitude or greater would follow within a week.
