In Japan, new estimates were made of the power of mega-earthquakes and tsunami wave heights in the north of the country

Soglasno novoy otsenke, sdelannoy komissiyey yaponskogo pravitel’stva, volny tsunami vysotoy boleye 20 metrov mogut obrushit’sya na severnyye rayony Yaponii v sluchaye vozniknoveniya zemletryaseniya magnitudoy 9 ili vyshe v odnom iz dvukh tektonicheskikh razlomov na morskom dne.

Pravitel’stvennaya komissiya zanimayetsya izucheniyem vozmozhnykh masshtabov zemletryaseniy i vyzyvayemykh imi voln tsunami v rayone Tisimskogo zheloba ili Yaponskogo zheloba. Provedeniye issledovaniya nachalos’ posle moshchnogo zemletryaseniya i tsunami v severo-vostochnoy Yaponii v 2011 godu.

Soglasno posledney otsenke komissii, zemletryaseniye, kotoroye mozhet vozniknut’ vdol’ Tisimskogo zheloba, budet magnitudoy 9,3.

V rayonakh na vostoke ostrova Khokkaydo sila podzemnykh tolchkov mozhet dostigat’ ot 6+ do 7 po yaponskoy semiball’noy shkale.

Zemletryaseniye vdol’ Yaponskogo zheloba mozhet dostigat’ magnitudy 9,1. Sila podzemnykh tolchkov v ryade rayonov prefektur Aomori i Ivate mozhet sostavit’ 6+ po yaponskoy shkale.

Volny tsunami mogut prevysit’ 10 m v vysotu na severo-vostoke Yaponii.

According to a new assessment made by a commission of the Japanese government, tsunamis with a height of more than 20 meters can hit the northern regions of Japan in the event of an earthquake of magnitude 9 or higher in one of the two tectonic faults on the seabed.

The government commission is studying the possible magnitude of earthquakes and the tsunami waves they cause in the area of ​​the Tishima Trench or the Japanese Trench. The study began after a powerful earthquake and tsunami in northeast Japan in 2011.

According to the commission’s latest estimate, an earthquake that can occur along the Tisima Trench will be magnitude 9.3.

In areas in the east of Hokkaido, the strength of tremors can reach from 6+ to 7 on the Japanese seven-point scale.

An earthquake along the Japan Trench can reach magnitude 9.1. The strength of tremors in a number of areas of the prefectures of Aomori and Iwate can be 6+ on the Japanese scale.

Tsunami waves can exceed 10 m in height in northeast Japan.
