South Primorye shifted by 4 cm after the earthquake in Japan in 2011

Scientists have found that the crust of southern Primorye and Vladivostok in the earthquake in Japan March 11, 2011 shifted to four centimeters in the direction of the earthquake's epicenter, said on Thursday the press service of the Far Eastern Federal University (Palo), which conducted the study of the Earth's crust.

Eleventh March 2011 in the north-east Japan earthquake with magnitude 9.0, which was officially named the Great Earthquake. It caused a tsunami that reached a height of 30-40 meters. The disaster killed or missing, more than 19 thousand people. Nearly 380,000 homes were destroyed or destruction.

"Ph.D., assistant professor of geodesy, land management and cadastre Nikolay Shestakov and colleagues from Palo, FEB RAS institutes and foreign universities conducted a study and simulation of motion and deformation of the Earth's crust in East Asia and the Far East of Russia, caused by a strong earthquake in the last century March 11, 2012, "- said in a statement.

According to research scientists, all of southern Primorye, Vladivostok and the surrounding area have moved in the direction of the epicenter of more than four centimeters within minutes after the main shock.

"Similar coseismic displacement magnitude of about eight millimeters were registered in Blagoveshchensk. Korean Peninsula is also shifted to the east by an amount of 10 to 50 millimeters," — noted in a release.

At the same time, scientists are called "worthless" displacement of the earth's crust in the regions of Primorye and the Korean Peninsula as compared to changes on the east coast of Japan, where the Earth's surface is moved by more than five meters and down — on one.

"The data on the peculiarities of the earthquake and its characteristics were obtained through the use of global satellite positioning GPS and GLONASS, the scientific and practical application of which over ten years engaged in the department of astronomy and geodesy Palo" — to be confirmed in a statement.

According to the press service, the study scientists Palo published in international scientific journals Tectonophysics and Terra Nova.
