The 2010 Eureka earthquake occurred on January 9 at 4:27:38 pm PST offshore of Humboldt County, California, United States. The magnitude was measured 6.5 on the moment magnitude scale, and its epicenter was located offshore in the Pacific Ocean 33 miles (53 km) west of the nearest major city, Eureka.[1][3][5][4][6] Additionally, there was a separate earthquake further offshore of Eureka on February 4 with a slightly lower magnitude of 5.9.[7] It was also the most significant earthquake in the Eureka area in terms of magnitude since the 1992 Cape Mendocino earthquakes.[8] It was felt from Santa Cruz County, California in the south, to Eugene, Oregon in the north and to the east as far as Reno, Nevada.[3]

Impact

Structural damage was inflicted among older Victorian houses, power was severed for several hours, and windows were shattered. In addition, 28,000 customers of Pacific Gas and Electric Co., mostly those from Humboldt County, were left without electricity and phone services as a result.[5]

In Eureka, the Old Town Bar and Grill building was previously believed to be severely damaged beyond repair and ordered demolished by the city, until a developer purchased and renovated it in 2011.[9] The town's high school, known as Eureka High School, and the Bayshore Mall were damaged and briefly closed, though both were later reopened with close to full services. An auditorium at Eureka High remained closed over concerns regarding its structural safety as of June 15, 2010.[10] A total of 463 buildings sustained damage as a result of the earthquake, leaving roughly $43 million in losses.[11]
