NASA detected a tsunami using signals in the atmosphere, not ocean sensors

A powerful earthquake off Russia's Kamchatka Peninsula provided a real-world test for NASA's new GUARDIAN system. This experimental technology detected subtle atmospheric pressure waves caused by the resulting tsunami, sending alerts to researchers within minutes. This space-based monitoring offers a crucial early warning, potentially adding valuable time for coastal communities facing threats.
