What Happened
This animation shows how, following a massive earthquake off Russia on July 29, 2025, GUARDIAN flagged an incoming wave west of Hawaii some 32 minutes before it made landfall and was detected by tide gauges (shown in blue).
Why It Matters
Credit: NASA’s Scientific Visualization Studio A new data visualization illustrates how an experimental NASA technology can provide extra lead time to communities in the path of a tsunami.
Key Details
- Called GUARDIAN (GNSS Upper Atmospheric Real-time Disaster Information and Alert Network), the software detects slight distortions in satellite navigation signals to spot hazards on the move..
- The animation breaks down a real-life case study: last summer’s massive Kamchatka earthquake and the tsunami that it sent racing across the Pacific and towards Hawaii at over 500 mph (805 kph).
- The visualization shows the magnitude 8.8 earthquake (seen in purple) strike off the Russian coast on July 29, 2025, triggering the tsunami.
- The red, orange, yellow, and green ringlets represent real-time readings from ground stations tracking GPS and other navigational satellite signals.
