FAST EVALUATION OF TSUNAMI WAVES HEIGHTS AROUND KAMCHATKA AND KURIL ISLANDS
In this paper, we consider the problem of fast wave heights numerical evaluation of hypothetical tsunami along Pacific coast of Kamchatka Peninsula and the Kuril Islands. We focus on PC-based fast numerical calculation of tsunami wave propagation according to the classical shallow water approximatio...
