Abstract
A new tsunami disaster mitigation scheme named here “Three-Level Disaster Management”, includes three disaster scenarios i.e., 1)Disaster Prevention Level, 2)Disaster Mitigation Level, 3)Maximum Evacuation Level. The Maximum Evacuation Level is to ensure safe evacuation and to minimize tsunami casualties (i.e., possibly Zero Tsunami Casualties) even for the case. The Disaster Mitigation Level is to ensure early recovery by reducing the damage and preparing for the recovery.
