NASA Satellite Reveals Dispersive, Pacific-Wide Tsunami Pattern
NASA’s SWOT satellite captured unprecedented high‑resolution, wide‑swath observations of a Pacific-wide tsunami from the Kuril‑Kamchatka earthquake, showing dispersive wave behavior that challenges the traditional non‑dispersive view; by combining SWOT with DART buoy data and inversion analyses, researchers refined the earthquake rupture to about 400 km and highlighted how integrating multiple data sources could improve future tsunami forecasting and warnings.
