The video discusses the historical tsunami event in Potidaea in 479 BC, believed to be caused by Poseidon but likely a natural tsunami. It explains how tsunamis form from underwater energy sources like earthquakes and volcanic eruptions, and how they differ from regular waves. The video details the dynamics of tsunamis, including wave shoaling and their devastating impact on coastal areas. Historical events like the 2004 Indian Ocean tsunami are highlighted, emphasizing the massive destruction and loss of life. The video concludes with current efforts to mitigate tsunami damage, such as sea walls and early detection systems, while acknowledging the challenges faced, as seen in the 2011 Fukushima disaster.
