The numerical model based on the variational principle was adopted to simulate tsunamis by the past Nankai or Hyuganada earthquake tsunamis to study the characteristics of tsunami propagation off the south of Kyushu including the southwestern islands. The MPS model was also applied to numerical computation of tsunami generation in Kagoshima Bay due to the inflow of assumed mass and velocity from partially collapsed Sakurajima Island.}, title = {南西諸島を含む九州南部沿岸域の津波脆弱性の検討}, year = {} }
