NASA and the French space agency's SWOT satellite have captured a rare event, a Pacific-wide Tsunami triggered by an 8.8

magnitude earthquake that struck the Kuril-Kamchatka subduction zone on July 29, 2025. They captured the event,

revealing a complex, braided pattern of energy dispersing across hundreds of miles. This challenges traditional

assumptions about tsunami behaviour, which is likely a single neat crest racing across the basins. The new experiment

suggests current physics models need revision, especially regarding 'non-dispersive' wave packets.

Detailed look at Giant Tsunami

The Surface Water Ocean Topography (SWOT) satellite captured a detailed look at the tsunami, showing a complex pattern

of waves dispersing and scattering across the ocean. The image shows a more intricate process, with waves breaking up

and dispersing in multiple directions. The SWOT satellite's advanced technology enabled scientists to map a 75-mile-wide

swath of sea surface height in a single pass. According to study lead author Angel Ruiz-Angulo, "SWOT data is like a new

pair of glasses, allowing us to see the tsunami in unprecedented detail".
