Tsunamis in the Okhotsk Sea: results of numerical simulation and analysis of historical data

Reporter: Chubarov L.

The content of the report is based on the materials obtained by the authors as a result of computational experiments and analysis of historical information about the tsunamis in the Sea of Okhotsk. The main attention was focused on the seismogenic tsunamis associated with earthquakes occurring in the Kuril-Kamchatka region. Evaluation of tsunami manifestations near the Sea of Okhotsk coast demonstrated the real danger (wave heights of more than 2 m) which arise after an undersea earthquake on the shelf and continental slope of the Kuril island arc with magnitudes over Mw=8.4. Mega earthquakes (with a magnitude of Mw=9.0 or more) lead to intense penetration of the tsunami energy into the waters of the Sea of Okhotsk with the capture of the energy on the Sakhalin shelf, the northern part of the Okhotsk Sea coast and the west coast of Kamchatka. Wave heights in the area of Okhotsk and Magadan, in this case, can reach 10 m. In addition to pure research interest, this results are directly focused on the modernization of the National tsunami warning system.

The work was supported by the Russian Foundation for Basic Research (projects 12-05-00894, 12-07-00406), by the Program of Integration Research, SB RAS (projects 117A, 37B), and by the Grant Council of the President of Russian Federation for state support of leading schientific schools of RF (project NSh-6293.2012.9).
