Generation of tsunami hazard map

Abstract

The East Sea surrounded by Korea, Japan and Russia is one of the most vulnerable places to unexpected tsunami attacks in the world. A number of tsunamis have occurred during last decades in the region. By using a numerical model based on the shallow-water theory, tsunami run-up heights along the Eastern Coast of Korea are computed for the 1983 Central East Sea Tsunami. Computed run-up heights are compared with field observations. The tsunami run-up process at Imwon Port where severe damages occurred by the 1983 Central East Sea Tsunami is first simulated with a high accuracy. At Imwon, a tsunami hazard map will then be developed based on the numerical predictions and field survey of historical tsunami events.
