Understanding Tsunamis

The video explains tsunamis, their causes, and effects. Tsunamis are large waves caused by underwater earthquakes, often occurring near tectonic plate boundaries. They travel fast in deep water but grow in height as they approach land, causing massive destruction. The 2004 Indian Ocean tsunami is highlighted as a devastating event. Tsunami warning systems, like the Pacific Tsunami Warning Center, are crucial for alerting populations and minimizing casualties.
