FOG BLOG U.S. LOG: CALIFORNIA 5.3 EARTHQUAKE, 2ND IN ONLY A COUPLE OF WEEKS!

Earthquake: Magnitude 5.4 quake hits Northern California days after deadly temblor A magnitude 5.4 earthquake hit Humboldt County on New Year’s Day, rattling an area of Northern California that was still recovering from a deadly temblor just before Christmas.

The epicenter of Sunday morning’s earthquake was about 26 miles from Eureka and nine miles from Rio Dell, the city hit hardest by the Dec. 20 quake, according to the U.S. Geological Survey. Residents reported violent shaking that started Sunday at 10:35 a.m., rattling church services and New Year’s Day brunches.

The temblor came 12 days after a magnitude 6.4 quake killed two people, left a dozen injured and caused widespread damage in Rio Dell, a lumber town 25 miles south of Eureka with a population of about 3,500. Dozens of buildings were red-tagged in that earthquake, leaving families homeless for the holidays. Residents were under a boil-water order until last Wednesday.

There was additional damage in Rio Dell from Sunday’s quake, which residents and officials described as a violent jolt, rather than prolonged shaking. It was not immediately clear how many structures were affected or whether they had sustained damage in the first quake.

The county is urging residents to report damage from the earthquake to emergency officials.

“We’re encouraging community members to be prepared for aftershocks,” said Cati Gallardo, public information officer for Humboldt County.

About 30% of Rio Dell residents are without water, and about half are without power, Humboldt County said at 5 p.m. Sunday. Pacific Gas and Electric estimated that nearly 1,100 households were without electricity at about noon Sunday, falling to 300 by 5 p.m. Some residents reported losing phone service and Internet access.

Sunday’s earthquake was large enough to trigger the state’s early warning system, which is designed to send alerts to residents. Some residents reported receiving an alert several seconds before the earthquake hit; others said alerts showed up after the shaking had stopped.

Videos taken by residents in Rio Dell and nearby towns, including Scotia and Fortuna, showed a violent jolt that dislodged books and other objects from shelves and sent televisions crashing to the ground. Doorbell cameras captured minivans swaying back and forth in a parking lot and the wheels of a lightweight truck briefly leaving the ground.
