Japan quake moved sea bed 24 metres: coastguard

TOKYO - THE seabed near the epicentre of the massive earthquake that rocked Japan last month was shifted 24m by the tremor, the country's coastguard said on Wednesday.

Sensors found that one part of the ocean floor had been stretched to a point 24m east-southeast of its position before the 9.0 undersea quake, which triggered a massive tsunami that engulfed large areas of Japan's northeast coast.

Which direction?............

[driftdiver]

"stretched to a point 24m east-southeast of its position before the 9.0 undersea quake"

[wxgesr]

“24m east-southeast of its position before the 9.0 undersea quake”

My guess would be ESE.

[Red Badger]

The US Geological Survey (USGS) said in March that the force of the quake moved Honshu - Japan's main island - by 2.4m.

Revelation 6:14 (New International Version, ©2011) 14 The heavens receded like a scroll being rolled up, and every mountain and island was removed from its place.

I was thinking UP or DOWN................

[TigerLikesRooster]

right above the epicenter: moved by 24 meters to the S. East and rose by 3 meters

50km from the epicenter: moved by 15 meters to the S. East and lowered by 60cm

What else on the surface of the earth also moved 24m?

[PetroniusMaximus]

“What else on the surface of the earth also moved 24m?”

I moved some logs in the backyard...

[Red_Devil 232]

Did you have to move them 24m so they were back in their original location?

[glorgau]

I wonder if this affects any property lines.

[TigerLikesRooster]

Actually some news report mentioned it a couple of weeks ago. Land survey has to be redone. In many cases, things(markers) are not where they should be.:-)

[null and void]

If (God forbid!) Japan had America’s lawyers no rebuilding could be done until the new property lines worked their way through the court system.

[patton]

Good point. I wonder how they handle that?

[ken5050]

Question: The quake measured a 9.0 Is there a theoretical maximum for the size/intensity of a quake? Is that number based upon the geology of plate tectonics?

[epithermal]

Interesting question that I had not thought about much. I know the Japan earthquake is one of the largest ever recorded, and I don’t know of any magnitude 10.

If you are really interested in an answer, you might ask here:

Do you have a question about volcanoes, earthquakes, mountains, rocks, maps, ground water, lakes, or rivers?

Thanks..I'll do so, and let you know. The hurricane and tornado scales have actual upper limits, based upon maximum wind velocity...

One would assume there has to be a limit for earthquakes...a 10.0 is what, 1000x STRONGER than the Jap quake...I guess it's reached when the mantle/crust cracks wide open?

That scripture sounds more like what an earthquake at the Yellowstone caldera would do. That thing is miles across. It is said if it blows it could even effect the flow of the great lakes...plus lose 1/2 of the western areas...

[goat granny]

oops, that would be a mega volcanic blast...sorry for the mistake
