Title: Earthquake
Post by: Alicat on August 02, 2006, 08:19:06 PM
Y'all up there in SF just feel the 8:08 quake? Was up north near Petaluma. Someone just called me from SF and felt it big time.

it felt pretty strong here.   It's been downgraded to a 4.4, but was a 4.7 for a while.  Seems like the western part of SF felt it harder than other parts.  Check these links out:

It seemed short and sharp -- windows rattled loudly for a couple seconds.

Years ago I was in SJ at a Sharks game and felt a significant quake. Kinda exciting. The train ride home took like 4x normal rate as someone had to inspect every foot of the track/rail before the train could progress. That sucked.

This is interesting, posted by someone on a message board:

"The West Coast is riddled with fault lines, thus earthquakes do not project as far as on the East Coast, which has few fault lines, and is primarily hard rock - that's why an earthquake of moderate strength can be felt up and down the East Coast."

Makes sense to me; anyone here know if that's actually a true statement?


Meanwhile Faux News apparently ran this actual screen-crawl earlier: "No Tsunami Expected After East Coast Earthquake".

Oy.

Can't confirm at the moment if that explanation is exactly the reason, but in general, yes, due to its geology Eastern quakes are more akin to dropping a stone in a calm pond, they radiate out further, feeling much like a waterbed, and while that sometimes happens here, often in the Pacific Rim its more like a jolt, depending of course on the magnitude and your distance from epicenter.  Here's USGS info on history of quakes in each state: http://earthquake.usgs.gov/earthquakes/states/

It was a 3.6 near San Leandro at 9:57am

Same location as last night's quake (which I did feel).  I did not feel the one this morning, at Pine and Battery...

Well, I am certified to teach Earth Science, but not necessarily a true earthquake expert.  But, it seems totally logical that vibrations don't travel well through cracks in the crust out here, where back East, the crust is all connected, and vibrations just transfer more efficiently.  It's amazing how far away this earthquake was felt.

I fell left out, just not feeling the shaking. Darn it. Seeing news today about hurricane devastation and damage, I'd be so much more fearful of all that other $h!t than some shaking.
