Monday's earthquake was wimpy, but useful.

An earthquake early warning system being tested in California gave seismologists in Pasadena up to 30 seconds to prepare for Monday morning’s temblor in the desert of Riverside County.
“It was right,” said Kate Hutton, a seismologist with Caltech. “I sat really still to see if I could feel it and it worked.”
-- LA Times

This system can't predict earthquakes, but it can transmit an "Earthquake... incoming!" signal out from the epicenter faster than the ground waves propagate, giving people more than 20 miles away enough seconds to drop and cover, hit the brakes on the train, move away from the window, etc. Japan has had a national system like this for several years, and California is looking into implementing one.

By the way... for those of you who don't live in earthquake country, this is Dr. Kate Hutton:

She is southern California's Earthquakes SpokesExpert. Whenever a quake triggers news coverage, whether it be national TV or a local radio broadcast, chances are we'll hear the reassuring tones of Captain Kate explaining it all to us.

Outside of entertainers, she's probably one of the most visible out lesbians in the world. Unsurprisingly, she is a dyke icon in California.

Absently checking local seismometers to see what's shakin' this week...


Seriously, where's all the little ordinary bumpity bumps that don't make the news but are there all the time? It's been too quiet lately.


It makes me think something's holding it's breath. And if that something is named Elsinore, erk. (I find it oddly fitting that the Elsinore Fault is the big one that threatens my home. That's the red line just to the right of Santa Ana. My home is below the first a in Santa. San Andreas is the red line further inland that goes by Palmdale; there's more mountains between me and it.)

sepdet: (SephiroWTF)
  • Long rolling earthquake, cat sleeps through it: M6.5+, but 100 miles away and/or inland so coastal mountains blocking full strength.
  • Long rattling or hard shaking, cat wakes up and stays awake but doesn't hide: M6.5+, about 30 miles away.
  • Long rolling, shuddering or swaying earthquake, cat bolts for cover: M6.5+, distance > 50 miles with no intervening mountains (meaning San Diego or Los Angeles.) 
  • [NEW 10.40PST 4/22/12] Strong shake, rattle and shudder, cat wakes up and then goes back to sleep: about M4, but the epicenter is within 5 miles. 

Continuing to collect data... 

Update: hey, cool, this is what it sounded like (here with a bit more bookshelf rumble):

Wow. MONSTER quake in Baja California about 5 minutes ago.

That's the biggest and longest one I've felt so far. I'm actually dizzy-- it feels like the ground's still moving, when it isn't. Rock and roll, rock and roll. Noisy, too. All the parrots freaked out and fled.

I'm afraid there's going to be damage from this one. I'm just to the right of the "Zoom In" box, which is a fair distance from the epicenter.

Trekqueen and other SoCal folks: here's the Did You Feel It? USGS questionnaire for this one.


Here's something I've never seen before: it appears to be rattling all up and down the coast. There's always a lot of quakes every day anyway, but that's more than usual in an hour.
