지진해일 예측 및 통보 체계에 대한 지진해일 시나리오 DB와 수치모의기법의 활용

Application of tsunami scenario database and numerical simulation to tsunami warning and notification process

Over a decade since 2007, Korea Meteorological Administration (KMA) has constructed and modified tsunami scenario database in order to issue tsunami warning soon after a large offshore earthquake and when tsunami is expected to affect Korean coasts. Based on the scenario tsunami database, KMA has improved tsunami issuance criteria and notification process. Moreover, we have developed numerical simulation process using parallelized code of tsunami modeling program. This will be used to provide additional and detailed tsunami information with better accuracy. On the basis of this achievement, it is needed to improve the system and process to be faster and more accurate. Furthermore, researches on non-typical sources of tsunami and complexity and non-linearity near the coast are needed for the coming decade.
