is the Hearth of what happened on March 25 earthquake was located opposite the island of Paramushir in the area of the deep trench. The earthquake occurred not in the most active part of the seismogenic zone, the probability of a stronger earthquake in this area is small. However, close to this area is a seismic gap. It is there in the next few days increased the risk of new seismic events with a magnitude up to 7.7 – said Solomatin.
First tsunami wave approached the North-Kurilsk
Earthquake that occurred off the Kuril Islands, felt the residents of Kamchatka. Says Alexey Solomatin, the inhabitants of this region there is no reason to panic. In Petropavlovsk-Kamchatsky even under the most adverse scenario, the strength of tremors is unlikely to reach 7 points. The seismic resistance of buildings in the city designed for 7-9 points.
However, according to long-term prognosis, the risk in the future is a seismic gap in the area of the southern Kamchatka and Avacha Bay.
“the Probability of strong earthquake with the seismic effect of up to 9 points in Petropavlovsk-Kamchatsky is estimated at 40-50 percent for the next five years,” he said, stressing that these data should be an incentive to increase the pace of work on seismic reinforcement of buildings and structures.
the height of the tsunami waves from the North-Kurilsk has amounted to two feet
Also, you need to watch for earthquake precursors, to put into operation a system of operational warning of strong and catastrophic szemletryaseniya for the cities of Petropavlovsk-Kamchatsky, Yelizovo and Vilyuchinsk. Over it is now a group of scientists under the supervision of the Director of the Institute Alexei Ozerov.
Recall that March 25 at 02:49 UTC Southeast of Paramushir island (North Kuriles) at a depth of about 50 km, an earthquake with a magnitude of 7.5. In the Kuril Islands declared a tsunami threat. In Petropavlovsk-Kamchatka earthquake caused tremors to 5 points.
