A tsunami is a series of massive ocean waves generated by sudden shifts in the seafloor, typically caused by underwater earthquakes, volcanic eruptions, or landslides. Unlike regular waves, tsunamis travel at jet-like speeds in deep water, often exceeding 500 mph, and grow dramatically in height as they approach shallow coastlines. Understanding their formation and behavior is crucial for developing early warning systems and improving coastal safety measures. #tsunamiscience #geophysics #natural
