The largest source region for tsunamis is in the Pacific Ocean with 71% of all occurrences. The remaining occurrences of tsunamis happen in the Mediterranean Sea (15%), Caribbean Sea and Atlantic Ocean (7%), Indian Ocean (6%), and finally the Black Sea (1%). Of all tsunamis, 83% are produced directly by earthquakes.
Drowning is the most common cause of death associated with a tsunami. Tsunami waves and the receding water are also very destructive to structures in the run-up zone. Some other associated hazards include: flooding, floating debris, contamination of drinking water, fires, explosions, and disease.
A tsunami is a naturally occurring series of waves in a body of water that results when a rapid, large-scale disturbance is caused by an earthquake, landslide, volcanic eruption, or an extra-terrestrial impact event. Although a tsunami cannot be prevented, the impact of a tsunami can be mitigated through community preparedness, timely warnings, and effective response.
