What is the safe place to escape from tsunami?
If in any case, one cannot escape the tsunami, then he/she should go to an upper storey of a sturdy building or climb onto a roof or up a tree. Or grab a floating object and hang on until help arrives. One should remember that boats are usually safer in water deeper than 100 metres than if they are on the shore.
Can you survive a tsunami by swimming under it?
No. Because of their long wavelength, tsunamis act as shallow water waves. One property of shallow water waves is that the horizontal fluid velocities under the wave are independent of depth.
Is it safer to be in a boat during a tsunami?
Boats are safer from tsunami damage while in the deep ocean ( > 100 m) rather than moored in a harbor. But, do not risk your life and attempt to motor your boat into deep water if it is too close to wave arrival time. Anticipate slowdowns caused by traffic gridlock and hundreds of other boaters heading out to sea. 4.
Is it better to be inside or outside during a tsunami?
If indoors, DROP under a sturdy table or object, COVER your head and neck and HOLD ON. If outdoors, move to a clear area if you can safely do so – away from trees, beach cliffs, signs and other hazards – and drop* to the ground. If you are outside of a tsunami hazard zone, stay where you are.

How long does a tsunami last?
Large tsunamis may continue for days in some locations, reaching their peak often a couple of hours after arrival and gradually tapering off after that. The time between tsunami crests (the tsunami’s period) ranges from approximately five minutes to two hours. Dangerous tsunami currents can last for days.
