9.0 Earthquake strikes Japan


Recommended Posts

looking at the data from the christinsburg, va. well this is on of the biggest oscillations ever there, and the first time the water rose to the ground level

the biggest is 2.85' image below

todays quake looks like 2.7'

Observation well 27F2 SOW 019, located in Christiansburg, Va., is sensitive to teleseismic waves generated by large earthquakes (usually greater than magnitude 6.0) that occur around the world. This well is 450 feet deep, finished in carbonate rocks of the Elbrook Formation, and water enters the well via fractures or cracks in the rock. Compression and expansion of these fractures by seismic waves cause the water to be drawn in and out of the well, similar to the way bellows work. As ground water moves in and out of the well, the water level in the well rapidly rises and falls. This water-level oscillation is recorded at 5-minute intervals by a pressure transducer and data logger maintained by the Virginia Department of Environmental Quality. Every hour, these data are transmitted via satellite to a computer located at the U.S. Geological Survey Virginia Water Science Center in Richmond, Va. Below is a list of recent earthquakes that caused a water-level response in this well. Click on the location link in the table below to see a hydrograph of the response.

Amazing video and pics. I find it amazing that I heard nothing about it in school. No teachers mentioned it at all. I knew about it but I was kind of dissapointed I couldn't hear more about it until I got home. I guess it just wasn't important enough. rolleyes.gif

Not surprising these days. Japanese earthquakes are not on the state end of year tests.

We (well, some of us) met before school started and decided that due to the sensitive nature of the events and with several students having family in Japan, we should avoid it. This could have been traumatic for some of the kids I work with.

This would have been great for my class, but I could see it freaking some of the kids out.

This isa very cool phenomenon. Great explanation at the end

neat location. what was the sumatra measurement there?

Yeah...but this is for another topic. lol.

Makes sense. I just would have rather seen it. We learn precalc, history, etc. every day. The only valid reason for not taking at least part of the class for the quake is how it affects students personally.

Makes sense. I guess I just wish I could have seen it live. For me it would have been more interesting then my latin, pre-calc, us history...well any class really. Still amazing footage watching it now, but sad at the same time.

The truly remarkable stuff, the stuff that was amazing to see live, was the tsunami hitting Sendai at around 2-3AM EST on CNN. Nothing else shown live since then has been comparable.

Yeah, I read through the thread this afternoon and saw all the posts from 2-3 am. Incredible. I actually woke up at 3am last night and saw a fb post about an earthquake but thought nothing of it and went back to bed. arrowheadsmiley.png

I may not remember half the crap I learned in school, but I do remember the OKC bombing and OJ Simpson verdict, because we watched it in school as it happened.

I had cancer, I have been seriously irradiated...

I can tell you this, people fear radiation because of the unknown effects it has.

Plus you can't see it or tell when you're getting exposed. We could be getting blasted right now and probably wouldn't know it til they announced it on the news.

<br />Other than Godzilla rising from Tokyo By, this event has had it all:<br />

<br />

Major quake (5th biggest ever recorded?)<br />

<br />

Huge tsunami<br />

Giant whirlpool<br />

Refineries blowing up<br />

Nuclear (possible) meltdown<br />

<br />

What else could they write?<br />

<br />

And has the missing train been located? The ship?<br />

<br /><br /><br />

The ship has, 81 people were airlifted.. not sure about the train

This is very cool to see.

I remember reading that the 1964 Alaska quake caused water levels in wells in South Africa to oscillate. At the time, I thought that was simply due to the sheer size of that event. But looking at that map, some relatively modest quakes on the opposite side of the globe have had an effect on that well.

Cool stuff.

Thanks for posting about this. That's remarkable and I'd never heard of that phenomena before. Nature's seismograph.

Clear steady video of the ground moving with water sloshing around. This one just creeped me out.

I let my 730 and 815 classes watch the news today, as well as my 12:00 class. I thought it was more important to do this today.

I wouldn't be sure Godzilla didn't cause this.

I have seen all the pictures of the whirlpool, but what caused it? I haven't found an explination for it.

yea i posted it this morning and didn't get much attention, amazing stuff for thousands of miles away here is a snapshot of the list of quakes it has measured
