In July 2025, NASA’s Guardian system detected a tsunami triggered by a massive earthquake near Kamchatka. Utilizing atmospheric disturbances and GNSS signals, Guardian issued alerts up to 30 minutes before landfall. This experimental technology enhances traditional warning systems, offering near-real-time, global monitoring and marking a significant advancement in disaster preparedness.
