See NASA’s GUARDIAN Catch a Tsunami

GUARDIAN (GNSS Upper Atmospheric Real-time Disaster Information and Alert Network) is an experimental NASA technology that detects tsunami hazards by analyzing satellite navigation signal distortions. During the Kamchatka earthquake on July 29, 2025, GUARDIAN provided early warnings, flagging an incoming tsunami 32 minutes before it reached Kauai, enhancing existing early warning systems for communities at risk.
