After and on a tsunami outbreak what will i do?

Not much: Unless you actually in the path of the giant wave, you should not suffer at all. It would be something you would read in the newspaper. If your livelihood is affected (a house destroyed, a working place damaged) then you might have monetary damages. Hopefully you have not had this happen.

Tsunami: If there is a mandatory evacuation - do that early on. Don't wait until the last minute. Don't try to drive through flood waters or on unsafer structures such as roads or bridges. Stay clear of downed power lines. Do not turn power lines back on until the power company or fire department indicate it is safe.
