| Research Abstract |
Hydraulic experiments on tsunami generation due to seabed deformation or landslides were performed employing the newly developed method to obtain water level with a laser beam, after which the results of water surface profiles of tsunamis were compared with those through the numerical models based on the variational principle or using the MPS method. 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.
