SWOT Satellite Reveals New Dispersive Dynamics in a Pacific Tsunami

NASA’s SWOT satellite captured the first high-resolution, wide-area view of a Pacific tsunami from the Kamchatka quake, revealing dispersive wave energy and complex interactions not predicted by classic non-dispersive models. By combining SWOT data with DART buoy measurements, researchers refined the rupture length to about 400 km and highlighted the potential for smarter, faster tsunami forecasting, though real-time use remains a challenge.
