A California earthquake occurred on Sunday night at 10:18 p.m. in the Pacific Ocean, about 50 miles off the coast of Eureka. According to Eureka police, the earthquake lasted about 20 to 30 seconds. As reported by USGS on March 10, 2014, “at this time (immediately after the mainshock) the probability of a strong and possibly damaging aftershock IN THE NEXT 7 DAYS is greater than 90 PERCENT.”

The USGS reports that the 6.9 earthquake is likely the largest shock and small aftershocks are to be expected during the next seven days. The likelihood that an “earthquake equal to or larger than this mainshock” will occur during the next seven days is “APPROXIMATELY 5 TO 10 PERCENT.”

As of Sunday night into early Monday morning, there are no reports of any damages or injuries, but more than 1,000 people reported feeling the earthquake on the USGS website.

Many of the people who reported the earthquake described it as a long, rolling shake that some said woke children or knocked items off shelves.

Eureka, which is a city of about 27,000 people, is located about 270 miles northwest of San Francisco and 100 miles south of the Oregon state line. In 2012, the area experienced a 5.6 earthquake which also caused no damage and injuries. In 2010, an offshore magnitude-6.5 quake, which occurred 25 miles closer to land than Sunday’s earthquake, caused bumps and cuts among residents and broke the glass in some buildings.

Aftershocks following the 6.9 earthquake on Sunday were felt across Northern California as far south as San Francisco and as far north as southern Oregon.

So far, even though the earthquake occurred 4.3 miles beneath the seabed, no tsunami warnings have been issued.
