Understanding Tsunamis and Their Effects

The video explains tsunamis, which are large tidal waves caused by disturbances like earthquakes or volcanoes. It describes how these disturbances create ripples in the sea, forming massive waves that can reach heights of meters and travel at high speeds. When these waves hit the coast, they can cause significant destruction, including loss of life and property. The term 'tsunami' originates from Japanese, meaning 'harbor wave'. The video also highlights the potential damage to harbors and ecosystems. Viewers are encouraged to like and subscribe for more content.
