Why in news
NASA and the French space agency's SWOT satellite captured the first detailed, high-resolution data of a Pacific-wide tsunami generated by a magnitude 8.8 earthquake in the Kuril-Kamchatka subduction zone.
Background
The SWOT satellite mapped a 75-mile swath of sea surface height during a single pass. The data revealed complex, braided wave patterns and dispersive behavior across hundreds of miles, challenging existing tsunami forecasting models.
Facts for Prelims
- S&TSWOT: A satellite mission by NASA and the French space agency to map sea surface height.
- FactThe tsunami was generated by a magnitude 8.8 earthquake in the Kuril-Kamchatka subduction zone.
