Citizen science, moderate temblor version

[ritaxis]

So we're all sitting around the house, doing what we do (after a delicious meal of sauteed mixed forest mushrooms -- grisette, chanterelle, and calyptrata -- and brown rice pilaf with dried craterellus. It rained yesterday!). The house begins to shake. Earthquake. Nobody moves. The house keeps shaking, harder and harder. And it goes on. So we all simultaneously, swiftly but without rushing, go to the nearest doorways and stand in them for what seems like a very very long time till the house stops shaking. As soon as we're sure it's over Emma and I both dive back to our computers to report it to the USGS recent earthquake site. Our earthquake isn't even on the map when we start filling out the forms!

The USGS computer automagically produces an earthquake report from the reports us citizens file and I think a few sensors here and there. Refreshing it a few minutes later gets an updated report which has been reviewed by a seismologist.

What we got: a moderate (5.6) quake centered 15 km northeast of San Jose City Hall, at 9 km deep, occuring at 8:04:59 pm PDT. Probability of strong aftershock in the next week: 30%. Of a quake stronger than the first one: 5-10%. Expecting 15 or so weak aftershocks. If you click around the site, you'll find shake maps, topo maps of the region, etc. The shake map is not up for this one yet, alas.

I love this stuff. I do have to admit I got kind of concerned when the earthquake kept going on and on.

I had never heard of the triangle of life guy until you mentioned him and I googled him. He's a transparent crank. It's simply untrue that people under sturdy objects such as desks, doorways, and cars are "crushed to death every time." In the Pretty Big One, there were very few deaths. One was a man trapped in a car for several days, who ultimately died of kidney failure days after he was got out of the car. The car did not crush him (though he was a bit crunched): it saved him, and if the rubble around him had been a bit shallower and he'd gotten to the hospital earlier he'd have lived.

The other deaths were in older buildings that had not been retrofitted yet, or most tragically, in a building next door to a building which had not been retrofitted, which fell to the side: and somebody who ran into a spooked horse on the highway.

In our case, the doorways were the closest objects to get under for the nice fellow and Emma. I could have gone under the desk I was at, except for my training! and my old stiff joints.
