Precautionary measures against Tsunamion May 12, 2010 at 4:42 am
In general, if you think tsunami is going to hit or the ground shakes under your feet or you hear there is a warning, you should move immediately to higher ground.
If you are at home and hear there is a tsunami warning, you should make sure people around you are also aware of the warning. You should quickly move to a safer place if you live in an evacuation zone. Follow the guidance of local emergency and law enforcement.
If you are at the beach or anywhere near the ocean and you feel the ground shake, move immediately to higher ground; DO NOT wait for a warning to be announced. Stay away from rivers and streams that lead to the ocean so that you would stay away from the beach and ocean. A regional tsunami from a local earthquake could smack some areas before a tsunami warning could be announced.
Tsunamis generated in distant locations will generally give a time lapse so that people can move to higher ground. For locally-generated tsunamis, where you might feel the ground shake, you may only have a few minutes so you should react sooner and move to higher ground.
