Understanding Tsunamis and Mega Tsunamis

The video discusses the causes of tsunamis, primarily earthquakes and landslides, and introduces the concept of megatsunamis. It highlights the 1958 Latoya Bay event as evidence of landslide-induced tsunamis. The La Palma megatsunami theory is explored, suggesting a future landslide could cause massive waves across the Atlantic, impacting the US East Coast. The video emphasizes the importance of understanding tsunamis to predict future occurrences.
