Whose work first explained how tsunamis are generated by sudden seafloor displacement?
Quick Answer
The explanation is tied to early tsunami science and was developed by many researchers in the 20th century. It showed that vertical movement of the ocean floor, often during large earthquakes, displaces water and creates long waves.
The Full Story
Tsunami generation was understood gradually as scientists studied earthquake damage and sea-level changes after major events. The key mechanism is sudden vertical movement of the seafloor, which pushes a huge volume of water upward or downward. As the waves travel across the ocean, they remain low in height but move extremely fast. This is why distant coasts can be hit hours later with devastating force. The science became essential to tsunami-warning systems around the Pacific and Indian oceans.
