According to PowerOutage.us, more than 70,000 people across Humboldt County, a majority of residents, were without power early Tuesday. Pacific Gas & Electric was working to restore power, Karges said, adding that "there is no time available" for when services might come back online.

State Route 11 at Fernbridge, the county’s oldest bridge, was closed early Tuesday because the bridge was cracked in four places, according to the California Highway Patrol incident log. Pictures on Twitter showed the concrete was fractured in several places. Crews were dispatched for an integrity check, Carsey said.

Exactly a year ago, the same area was hit by a magnitude 6.2 quake that shattered windows and caused some damage.

Yes, a decent quake, some building damage and I understand 2 deaths reported, hopefully no more

Yes, indeed, just a bit SE and further inland

@Astronuc That newspaper link has incorrect info and shows the event
well offshore. The 6.2 was on shore just a bit southeast of todays event

Looks like they are hoping to restore power by 10PM tonight...

Now they're saying no confirmed fatalities, some injuries and at least one structure fire (complicated by water mains breaking...).

Crap, now they are verifying 2 fatalities, although they said they were medical emergencies involving older folks. Still unfortunate.

Two people, a 72-year-old and an 83-year-old, were killed in Humboldt County as "a result of medical emergencies occurring during and/or just following the earthquake," officials said.

There was an M6.8 earthquake near Olympia, WA on Feb. 28, 2001, caused most likely by movement of the same plate, the Juan de Fuca plate. I remember that quake distinctly, as I was driving south on I-405 when I felt the whole highway moving under me for about 10 seconds. I thought there was something wrong with my car, but found out later that it was an earthquake.
