Abstract

Prognostic characteristics of hypothetical tsunamis in the East Sea are discussed based on numerical model simulations of linear long wave theory and wave ray for 28 source zones of tsunamigenic earthquake selected by the seismic gap theory. As a result, the propagation patterns of tsunamis due to hypothetical earthquake are presented and analyses also lead to selection of the geographical zones with low risk of tsunamis.

본 논문에서는 동해에서의 가상해저지진에 의한 지진해일의 예단적 특성에 대해 논하였는데 재해를 유발시킬 수 있는 지진해일의 근원역은 공백역이론으로부터 선택되었다. 선형장파이론에 근거한 수치모형과 구면좌표계상의 파향선방정식에 근거한 파향선추적산정모형을 채택하여 28개의 선정된 가상지진(4 경우 실제지진 포함)에 의한 지진해일 전파를 산정하는 데 적용되었다. 결과로서 동해안에 전파되는 지진해일 특성과 동해안의 해안역위치에서의 지진해일 분포가 산정되어 지진해일 재해위험도가 상대적으로 낮은 지리적 위치를 구획화하였다.
