NASA's SWOT satellite captures detailed tsunami imagery from space

NASA's SWOT satellite captured the first high-resolution imagery of a tsunami from space, revealing a more complex wave structure than previously understood. The data, collected after a July 29, 2025, earthquake, showed a large leading wave followed by smaller, stretched-out waves, challenging the long-held belief of a single energy pulse. This detailed observation, published in The Seismic Record, could improve tsunami warning systems by providing a clearer understanding of wave behavior in the open ocean.
