Earthquake and tsunami disaster that occurred in Japan last March turned out to have made significant changes to the conditions of the earth, more than estimated by previous researchers.
As quoted from dailymail site, it turned out great earthquake shifted the sea floor are elongate, to 79 feet or 24 meters. These findings have been published in the journal Science.
In the paper, the beach supervisor Japan released data from five instruments between 200-2004 geodesy which they placed along the fault line on the seabed, which it has caused the great earthquake.
One of the earlier instruments, even just above the epicenter of the quake in the scale of 9 on the Richter Scale that. The instrument was named MYGI station.
Apparently, measurements made stating that there had been a monitoring station that shift, up to 24 meters along the east-southeast direction from the previous location, which is measured in February 2011.
Not only that, the station also has been moving upwards to about 3 meters. Dr Mariko Sato, geodesy experts from Japan's coastal watchdog based in Tokyo, believes that the entire movement that occurred during the Japanese earthquake took place.
"The scale of this shift is almost two times larger than previously thought, when using terrestrial data," said Sato told the BBC website.
Given these findings the researchers cautioned that the possibility of gathering very large seismic pressure stored in the vicinity of the quake zone, fueling the risk of more deadly earthquake that anymore. The earthquake and tsunami itself had taken 24 thousand casualties and lost. (Umi) (vivanews.com)
