How can tsunamis be managed

It is important to have necessary supplies to last for several days after the event. Stores may not have food, and fresh water might be scarce. Keep emergency supplies in a backpack or container that can easily be carried.

In a locally generated tsunami, you may have only minutes to get to high ground, so be prepared ahead of time.

When a tsunami warning is issued, turn on local radio or television stations for more information on when to evacuate the tsunami evacuation zones. For locally generated tsunamis there may not be time for sirens or issued warnings.

Warning signs will come from natural surroundings: an earthquake longer than 20 seconds, sea water suddenly retreating, or a roaring sound coming from the ocean.

If any of those occur, evacuate immediately. Always evacuate inland or to higher ground. Avoid rivers and streams, since tsunami waters could funnel into the channels. A tsunami is never just one wave. There is always a series of waves with danger that can last for several hours. The first wave may not be the largest, so do not think it is safe to go back to the shore just because the first wave has passed. The first wave may clear the path for additional waves to move farther inland.

Always wait for an official message stating that it is safe before returning to a coastal area. When out in the deep ocean in a boat, do not try to come to shore; instead, stay out at sea and wait for an official message before returning to port.

Coastal populations are on the increase in many parts of the world, mostly due to the exploitation of sea resources or tourism-related activities. Adequate tsunami mitigation measures— such as tsunami warning systems, education, and land use planning—can be put in place to save lives, property, and the livelihoods of those living on the coast.

Although the impact of the disaster on the global insurance industry was minimal, it alerted the world to the dangers of tsunami hazards. Worldwide response to the disaster resulted in the establishment of the Indian Ocean Tsunami Warning and Mitigation System in Ten years hence, the world has seen two more earthquake-induced tsunami events—in the M8.
