SWOT Satellite Traced a Pacific Tsunami to Within 10 Kilometres of the Fault

A NASA satellite tracked a magnitude 8.8 earthquake tsunami across the Pacific Ocean with 1-centimetre precision and pinpointed exactly where the seafloor rupture was shallow enough to generate catastrophic coastal waves, solving a measurement problem that ground-based sensors have failed to crack for decades. Findings published in Science in March 2026 quantify how the Surface […] The post SWOT Satellite Traced a Pacific Tsunami to Within 10 Ki…
