Abstract

 The observation of atmospheric pressure fluctuation was carried out at Niigata University to predict generation of a gigantic tsunami. The atmospheric pressure changes were occurred by precipitation and a cold atmospheric current. The 3D numerical simulation of generation and propagation of acoustic gravity waves associated with tsunami was performed to investigate how acoustic gravity waves generate by the generation of tsunami. The negative atmospheric pressure wave was generated in the region where the subsidence of ocean floor occurred and propagated with decreasing its amplitude up to several hundred kms.
