How do people warn about tsunamis?

How do you manage a tsunami?

Plan evacuation routes from your home, school, workplace, or any other place you could be where tsunamis present a risk. If possible, pick areas (30 meters) above sea level or go as far as 3 kilometres inland, away from the coastline. If you cannot get this high or far, go as high or far as you can.

What should you never do during a tsunami?

If a Tsunami Warning is issued, NEVER go down to the beach to watch the waves come in. Do not try to surf the tsunami. If you are on a vessel in deep water and a tsunami warning has been issued, do not return to port. Vessels are safer from tsunami damage whilst in the deep ocean (>200 fathoms, 1200 ft, 400 m).

What should you do if you hear a tsunami warning?

• If you hear an official tsunami warning or detect signs of a tsunami, evacuate at once. A tsunami warning is issued when authorities are certain that a tsunami threat exists, and there may be little time to get out. • Take your emergency preparedness kit.

What’s the best way to escape a tsunami?

Is there a tsunami threat after an earthquake?

While the tsunami threat after an earthquake ( Indonesia 2018 Japan 2011 , Southeast Asia 2004) does allow a brief time to post a warning, often it is too little to save lives. In the case of earthquakes and volcanoes, the series of aftershocks or continued volcanic activity poses an ongoing threat in the midst of the chaos after the initial event.
