GUARDIAN Detects Tsunami Waves Faster Than Gauges
9.2
NASA's experimental GUARDIAN system detected ionospheric disturbances from the magnitude 8.8 Kamchatka earthquake on July 29, 2025, and tracked the resulting tsunami across the Pacific. GUARDIAN's AI flagged an incoming wave off Kauai 32 minutes before tide gauges, scanning more than 350 GNSS ground stations and offering a cost-effective complement to ocean-floor sensors for earlier warnings.
Key Points
- 1Detected GNSS signal distortions from the July 29, 2025 magnitude 8.8 Kamchatka earthquake within eight minutes
- 2Provides earlier warning by flagging an incoming wave off Kauai 32 minutes before tide-gauge detection
- 3Enables cost-effective augmentation of tsunami monitoring using existing GNSS networks and trained analysts
Scoring Rationale
Strong, credible real-world demonstration with high practical value; limited to experimental deployment and requires analyst interpretation.
