Posts: 1125 (05/18/09 12:42 AM) Reply Quote More Recent Posts Message Connection Block Invite	I remember a little one in Vancouver 6-9 years ago. I was on the computer and just felt a few waves side to side but it didn't feel like a long time. I think they said it was 2-3 seconds. No real tragedy, except the Starbucks logo fell off their main building in Seattle. And guess what --> earthquakes can be predicted in advance, just not by humans. The Discovery channel had this doc about some island off Italy that has regular earthquakes that sends tonnes of rocks down the land into the water and crushes all the wildlife like crabs and big fish or whatever, all but this species of octopus. Turns out they can sense well in advance when an earthquake is brewing and they all hightail it to the other side of the island before it happens. It was crazy seeing the underwater video, every single octopus got off the sea floor at the same moment and just got moving. I wish I could live under the sea; I know there's some crazy shit down there.

Still get that WTF moment of "am I supposed to actually DO something now or is this over in a matter of seconds and if I...oh nvm it's over" -SJ™

A 5.0 is freaking you all out at just 15 seconds? ::shakes head:: Whoever was asking about how it sounds, it sounds like a Mack truck passing by your house/apartment and all the windows. Its very distinctive and you dont even notice it until you see the shaking. Like SJ said, once you realize what it is, you just sorta get that "deer in the headlights" feel, unless you're near a chimney or parking structure/highway.

I remember Northridge like it was yesterday, that quake was fucking scary. I'm jes sayin' it felt like a stronger quake. Apparently this Starbucks thought it was strong enough to shatter its windows. Employees of a Starbucks located at Hawthorne and Artesia Boulevards work to clean up broken glass that shattered on the floor and reportedly injured one person who was taken to a nearby hospital.

If an earthquake ever hit New York, most of the buildings under 6-7 stories would easily crumble.

That one lasted long enough to go through the panicky wtf moment and into the full on holy shit moment when everything started falling off the walls and the floor was rising up to meet you before you could get your legs moving. Once you've gone through one of those, the smaller ones make you more jumpy, because you never know when it's just going to get worse and worse...

The most promising detection methods will probably involve low frequency "infra-sound", that people can't sense, which is caused by the movement of plates (among many other things). It's already been proven that many animals can detect these wavelengths, especially those that live in water. Couple infra-sound with probable electromagnetic changes, from different material in various strata being stressed from seismic movement, and we should be able to predict major earthquakes within a few decades. However, that information may come too late to do much good. It will also be highly dependent on the strength of the event, and many other variables. Even with extremely sensitive instruments, there will always be unexpected disasters.
