Tsunami Awareness and Response

The video discusses tsunamis, focusing on the 2004 Indian Ocean tsunami, its causes, and impacts. It explains how tsunamis are generated by underwater earthquakes and highlights the lack of warning systems at the time, which contributed to the disaster's severity. The video also covers the challenges of tsunami detection and the development of global warning systems like DART to prevent future tragedies.
