EUREKA, Calif. – A 5.0-magnitude earthquake hit about 120 miles off the Northern California early Sunday morning, near where a larger temblor prompted a brief tsunami warning last week, according to the U.S. Geological Survey (search).
The quake struck at 1:27 a.m. and was centered about 130 miles west of Eureka.
A Humboldt County (search) Sheriff's Department dispatcher said there were no immediate reports of damages or injuries.
A 7.0-magnitude quake struck about 80 miles off the coast Tuesday night prompting an hourlong tsunami warning from the California-Mexico border north to Vancouver Island, British Cofornians have had a string of significant earthquakes after several years of relative seismic calm. But seismologists say clusters of quakes do not necessarily mean the Big One is coming.
