Aftershock of San Simeon Quake Reported
A moderate aftershock of the Dec. 22 San Simeon earthquake rattled through the Central Coast on Tuesday, and the U.S. Geological Survey said it measured magnitude 4.0.
No damage or injuries were reported from the 10:25 a.m. temblor, which was centered 11 miles southwest of Paso Robles and was at a depth of two miles.
Geological Survey seismologist David Oppenheimer said that as of Tuesday, 5,522 aftershocks have been reported since the 6.5 main shock killed two women in Paso Robles and caused an estimated $250 million in damage.
The latest aftershock was the 18th measuring 4.0 or larger and the strongest since a magnitude 4.5 aftershock March 17.
There have been two other sizable aftershocks felt in the last week, including a 3.7 Sunday and a 3.6 Friday.
The 4.0 was felt Tuesday as far north as San Francisco, nearly 200 miles away, and south to Santa Maria.
