| Abstract: | A typical model of the source of a tsunami (“macroseismic source”) is suggested for use in approximate estimation of maximum
tsunami height using straightforward numerical modeling. In this paper the model is tested using three actual events: the
1952 North Kuril Is., 1971 Moneron, and 1994 Shikotan earthquakes, which excited considerable tsunamis at Russia’s Far East
coasts. Comparison of the maximum tsunami runup values as obtained in numerical experiments with observations of actual tsunamis
showed that the numerical model proposed here is suitable for crude estimation of tsunami runup and tsunami waiting times
for coastal population centers in the near zone of a tsunami source. |
