Hospital and government entities should establish comprehensive emergency plans for tsunami-prone communities. The evacuation of affected individulas before the arrival of the first tsunami wave should be a priority when a tsunami alert is issued.

Well-developed plans rely on collaboration and simulation to ensure relocation of affected persons to safe areas (such as shelters) and/or planning for appropriate escape routes. The inclusion of tsunami hazard and damage scenarios should be included (when appropriate) to identify suitable shelters, determine escape routes and consider the possibility of debris accumulation which can affect accessiblity of established routes.
