7+ Earthquake off the coast. Tsunami warning in place.

Eureka, Calif. — A strong earthquake was felt widely across Northern California on Thursday and authorities have issued a tsunami warning.

The quake struck at 10:44 a.m. west of Ferndale, a small city in coastal Humboldt County near the Oregon border, according to the U.S. Geological Survey.

It was felt as far south as San Francisco, where residents felt a rolling motion for several seconds. It was followed by smaller aftershocks.

The San Francisco Bay Area Rapid Transit District, known as BART, has stopped traffic in all directions through the underwater tunnel between San Francisco and Oakland.

At least 5.3 million people in California were under a tsunami warning after the magnitude 7.0 earthquake, the U.S. Geological Survey said in a yellow alert, which predicts localized but minimal damage.

More than 1.3 million people lived close enough to the quake that they could have felt it, the USGS estimated.

my point is sometimes these seem to get issued and there’s barely a ripple at the beach because it’s too far away.

If we only had someone on here who would go out there on a longboard and report back.

Lol at tsunami warning for a 7.0. I think only a 8.5+ could trigger anything more than a couple feet of a tsunami.

You’re thinking of a mega-tsunami.

There's an underground tunnel across the bay? 

How else do you think we move the homeless around? 
 

They usually slow trains after earthquakes and that’s already a shitshow, gonna be a mess with them closed.

Yep.  Bay Area Rapid Transit (BART) from Oakland to SF.  Plans for, or working on I forget, a second tube.

I’m here in the Bay Area in a hotel. Didn’t really feel anything, but the bartender said the light fixtures were swaying a little bit downstairs. I went for a run near the bay and all looked normal. Tsunami warning was canceled by the time I got back.

Right on the Tectonic Plate boundary.     Maybe 'The Big One" is queueing up.

I think the "Big One" will hit farther north. Washington or thereabouts. 

 

California will always just be relatively small ones. 

 

At least that's what I remember from my one geology class so many years ago.

The Cascadia Fault. It’s a subduction zone and that is where the truly big earthquakes happen. 

 

Sounds familiar. Same fault that caused Mt. St. Helens eruption, iirc.

except for the whole Great San Francisco Earthquake of 1906...thing.

 

Was that really a "big one"? Or just a medium to smallish one that destroyed a lot because nobody knew or cared how to build in an earthquake zone?

I'm not a geologist.   I think its safe to say if a true doomsday "big one" happens it doesn't matter how anything is built, shit is going to be very, very bad.

"At Cascadia, big quakes are believed to come roughly every 500 years, give or take a couple hundred. The last occurred in 1700."

“…the megathrust fault zone is not just one continuous structure, but is divided into at least four segments, each potentially somewhat insulated against movements of the others.”
“the causes of the segmentation: the rigid edge of the overriding North American continental plate… This variety in the continental rocks causes the incoming, more pliable oceanic plate to bend and twist to accommodate differences in overlying pressure. In some places, segments go down at relatively steep angles, in others at shallow ones.”
“...the Vancouver-Washington segment is quite smooth. This means that it may be more likely to rupture along its entire length at once, making it potentially the most dangerous section.”
“…the shallow subduction angle means it probably extends directly under Washington’s Olympic Peninsula. This might magnify any shaking on land.”

Damn.

All I remember being taught in school was that if you dive under your desk fast enough, you might just live.

 

That only works for nuclear explosions.

It's difficult to get too worked up about a warning coming from a state that puts a warning label on 99% of consumer products that they will give you cancer.  Someone should study how much the anxiety being created by all of the fear mongering is impacting the health of the citizens there.  There should be warning labels for their warning labels.  "WARNING: READING THIS LABEL MAY INCREASE ANXIETY LEVELS.  ANXIETY IS KNOWN TO CAUSE HEART ATTACKS, STROKE, AND EVEN WORSE MEDICAL CONDITIONS WE ARE NOT AT LIBERTY TO PUT ON A LABEL."
