A moderate earthquake off the coast of San Diego shook Orange County on Wednesday afternoon, jolting some residents as far north as Garden Grove but causing no damage.
The temblor occurred at 2:17 p.m. and was measured as a 4.3-magnitude quake, said Margaret Vinci, a staff member at the California Institute of Technology seismology lab in Pasadena. It was centered 42 miles west-northwest of San Diego.
A CalTech spokesman said the quake was probably too small to cause any damage, given that it was centered off the coast.
But the mild shaker prompted more than half a dozen calls to police agencies across the county from curious residents who wanted some confirmation that what they had felt was indeed a quake.
