TSUNAMI SIMULATION CONSIDERING INTERRELATED EARTHQUAKES AND ITS REMAINING PROBLEM

Abstract

 The tsunami height in Tokyo Bay caused by the interrelated-type earthquake near the Nankai Trough was simulated to examine the influence of the slip distribution among faults and the slip generating time lag between faults. About the time lag of slips, the maximum tsunami height in case that the slips occur having the time lag which the tsunami maximum height by each fault overlaps becomes more than twice of the case that all of the slips occur simultaneously. Moreover, it turned out that slip distribution which makes the tsunami height mathematically maximum is widely different from with the distribution using the knowledge of seismology.
