NASA Satellite Captures First Detailed Overhead View of Pacific Tsunami
SWOT satellite data revealed the tsunami’s leading wave exceeded 45 cm, followed by smaller waves, challenging prior models and aiding improved warnings, researchers said.
- On July 29, 2025, the SWOT satellite recorded a Pacific tsunami generated by a magnitude 8.8 earthquake in the Kuril-Kamchatka subduction zone, off Russia’s southeastern coast.
- SWOT's roughly 120-kilometer swath allowed researchers to image much more of the sea surface, and after years of mapping small currents, SWOT fluked a major tsunami combined with Deep-ocean Assessment and Reporting of Tsunamis buoys for broader analysis.
- Combining SWOT altimetry with three DART buoys, researchers found the rupture spanned roughly 400 kilometers and the leading wave exceeded 45 centimeters.
- Immediate implications include better risk assessment for coastal communities, as researchers say the satellite's detailed tracking could improve tsunami models and warning systems.
- The data challenge the assumption that big tsunamis travel as a single coherent wave, as researchers show SWOT could spot and track future tsunamis in real time for coastal communities.

On July 29, 2025, the earth trembled with extreme violence in front of the Kamchatka peninsula in Russia. An earthquake of magnitude 8.8 shook the subduction zone, generating a tsunami that spread throughout the Pacific. So far, it might seem like another geological news, but what happened in space 70 minutes later has changed our understanding of these phenomena. The SWOT satellite (Surface Water and Ocean Topography), a joint mission of NASA a…
