Thursday, 23 June 2011 07:27

USGS reported, that earthquake of magnitude 6.7 occurred at 21:50 UT off the coast of Japan, near the Iwate Prefecture. The epicenter was near Iwate Prefecture, located at a depth of 32 kilometers, 88 kilometers of the city of Hachinohe, 99 kilometers of the town of Morioka and 524 kilometers of Tokyo.

As currently reported Japanese newspaper Asahi- were not reports of casualties or damage. Immediately after the earthquake in Japan was declared a threat to the tSunami, which was canceled after an hour, in the absence of signals of approaching tSunamis. The centers of monitor tSunamis in the Pacific also canceled a tSunami threat.

Some media have reported about two earthquakes of magnitude more than 6, but in fact, in Japan there was only one earthquake of magnitude 6.7, another earthquake, a magnitude of 5.1 was only an hour earlier in the same area. Although there were no reports of casualties, it could be due to the fact that the epicenter was at sea, so the main threat from this earthquake was of a tSunami.

Iwate Prefecture located in the Tohoku region, is bordered with the prefecture of Aomori in northern Japan, Akita prefecture in the west and Miyagi Prefecture in southern Japan. The surface of Iwate Prefecture, consists of mountain ridges and plateaus between them lies Kitakamigava basin, where lives the majority of the population of Iwate Prefecture. This relief creates a special danger for the residents of the prefecture in the event of a tSunami.

Early, the cities of Iwate Prefecture suffered greatly from the effects of the tSunami, especially the city of Rikuzentakata, which is due to the tSunami on March 11, 2011 has been completely razed to the ground. And it was not the first time such a devastating tSunami impact on the city of Rikuzentakata- after a Chilean earthquake on May 23, 1960 tSunami also badly affected buildings of the city. Then, off the coast of South America in the Chilean coast was formed tSunami off the coast of Chile reached a height of 15-20 meters, as a result of this was destroyed several towns and washed away dozens of villages, killing all 10 thoUSAnd people. Within 22 hours, breaking more than 16 thoUSAnd kilometers in the morning May 24, 1960 tSunami approached the Pacific coast of Japan and the Soviet Far East.

On the coast of the Far East height of water, on average, was 3-5 meters, and on the Pacific coast of Japan tSunami height reached 9 meters in some places, which caused major damage to infrastructure of Iwate Prefecture.

Then, even in the Kuril Islands the maximum height of water was 4.5 meters, flooded homes on the coast and the pier. Washed away bridges and some buildings in Yuzhno-Kurilsk, the vessels derailed from their anchors. The tSunami from the Chilean earthquake was observed in all the Kurile Islands, the maximum height of tSunami was 4 meters on Shikotan and 2.2 meters on the island of Kunashir. Therefore, Russian seismologists were very careful to reports of an earthquake near Iwate Prefecture, which theoretically could cause a tSunami on the coast of the Far East of Russia, but in this case, the threat of tSunami was canceled.

It should be noted that earthquakes occur in Japan every day, but the majority are single and low-amplitude earthquakes. At this time, the main earthquake, as usual, was preceded by a series of foreshocks and the scientists predict earthquakes in the this area of Japan may go on for another month.
