university of tsukuba attempts seismic institute

International online ZhuanGao: according to Britain's daily mail reports on March 13th,each northeastern Japan coast has encountered when big earthquake hit years, scientists say, the earthquake power so huge, so that the earth itself will be moved 25 cm. In addition, the earthquake has changed the earth's rotation speed leads to the day long change.

The Italian national geophysical and volcano experts say, Japan institute of earthquake measuring 9.0 on the release of energy and amazing, it makes the earth's axis moved 25 centimeters, altered earth's rotation speed for day long and season length cause weak effect.

 

But in fact for huge earth, it has this kind of change is very small. University of Toronto professor Andrew meyer said: "if see before you ruler, 25 centimeters may appear very long. But in the whole earth,about to choose 25 cm before but very small. This move will change day long, also will change the gradient, affect season length, but these effects will be very, very small."

 

The U.S. geological survey's seismologists, Daniel mike that malah said, vast cracks underseas appear, the disaster has changed Japan's coastline, make maizuru, mobile _work_ 2.4 meters. He also warned that earthquakes can also lead to Japan, many bits of sinking below sea level will be permanently sank into the ground, "we used to see many underwater cities, that is sinking result".

 

Tokyo university, university of tsukuba attempts seismic institute and the see experts said the powerful earthquake every thousand years may will meet again. It may cause more earthquakes, and therefore must be more vigilant, Tokyo residents should for bigger earthquake hit ready.
