OT - BREAKING NEWS - 8.9 earthquake in Japan

[2Stater]

I'm really taxing my memory here, but I remember learning in high school that an earthquake is something like twice as powerful per decimal as the the previous on the Richter scale, meaning that a 6.5 earthquake is twice as powerful as a 6.4 earthquake. Am I remembering that correctly?

No, it's a log scale.  Because of the logarithmic basis of the scale, each whole number increase in magnitude represents a tenfold increase in measured amplitude.

Thanks Chech. I couldn't remember exactly, but I knew the ramp-up was serious.

Not that simple.

Having video links at work blocked, SUCKS!!!  

The most horrible video is the wall of debris (cars, houses, trees, boats) rushing across neighborhoods in Japan.  It's taken from a chopper, and you can see traffic on the roads trying to outrun it (NOT) and intersections with cars stopped and people running.  The wall of water finally hit a levee along the ocean and all of the debris spilled over as a muddy, mile-long wall of debris that made a huge waterfall.

I checked here to be sure.  Wiki wrong?  http://en.wikipedia.org/wiki/Richter_magnitude_scale

A couple of them seem to get away.

"Because of the logarithmic basis of the scale, each whole number increase in magnitude represents a tenfold increase in measured amplitude; in terms of energy, each whole number increase corresponds to an increase of about 31.6 times the amount of energy released, and each increase of 0.2 corresponds to a doubling of the energy released."

Sorry, I was off by .6

That, to me, is why an 8.9 is unimaginable.

Also salient that it was a shallow epicenter.

Off to work.  Later, dudes.

Wow, 24km is very shallow.

Years of cleanup and recovery.

Tsunami from Japan earthquake strikes Hawaii, not as big as expected

Yall ready to move this to halftime?

[Terrie1959]

Off to work.  Later, dudes.

have a good day!
