Satellite captures detailed view of tsunami's complex wave structure

sciencealert.com

A satellite has captured unprecedentedly detailed data of a tsunami, revealing it broke into multiple waves, challenging existing models. The Surface Water and Ocean Topography (SWOT) satellite observed a tsunami generated by an August 2025 earthquake, showing a large leading wave followed by smaller trailing waves, unlike the assumed single-wave propagation. This new data, collected by SWOT's wide swath and high resolution, could significantly improve tsunami prediction and warning systems for coastal communities.
