What's Happening?
NASA's GUARDIAN system, developed by the Jet Propulsion Laboratory, has demonstrated its ability to detect tsunamis by monitoring atmospheric waves. During a real-world test following a magnitude 8.8 earthquake off Russia's Kamchatka Peninsula, GUARDIAN detected pressure waves in the upper atmosphere within 20 minutes, issuing alerts before the tsunami reached Hawaii. The system uses Global Navigation Satellite Systems (GNSS) data to identify atmospheric disturbances caused by tsunamis, offering near-instantaneous monitoring and contributing to improved hazard assessment.
Why It's Important?
GUARDIAN represents a significant advancement in tsunami detection technology, providing faster and more reliable warnings. By utilizing GNSS data, the system offers a space-based monitoring solution that complements existing seismic and ocean-based sensors. This capability is crucial for enhancing global tsunami early warning systems and supporting evacuation efforts in vulnerable coastal communities. The system's ability to detect atmospheric disturbances quickly can help reduce the time needed to confirm a tsunami threat, potentially saving lives and minimizing damage.
