A powerful magnitude 8.8 earthquake off Russia\u2019s Kamchatka Peninsul<\/a>a recently triggered a tsunami that rippled across the Pacific Ocean. It gave NASA scientists<\/a> a real-world test of their new tsunami detection system. Researchers at the Jet Propulsion Laboratory (JPL) in Southern California say their experimental system, known as GUARDIAN (GNSS Upper Atmospheric Real-time Disaster Information and Alert Network), detected the tsunami by reading subtle disturbances in the upper atmosphere.<\/p>\n

\u201c[GUARDIAN] functioned to its full extent,\u201d said<\/a> Camille Martire, one of the system\u2019s developers at JPL. The system sent alerts to subscribed subject matter experts within 20 minutes of the earthquake, according to NASA\/JPL. It also confirmed signs of the tsunami roughly 30 to 40 minutes before the waves reached Hawaii <\/a>and other Pacific sites on July 29 local time. \u201cThose extra minutes of knowing something is coming could make a real difference when it comes to warning communities in the path,\u201d said JPL scientist Siddharth Krishnamoorthy.<\/p>\n

How GUARDIAN Works<\/p>\n

During a tsunami, large sections of the ocean rise and fall together, pushing air upward and generating low-frequency sound and gravity waves that travel outward into space. Those waves slightly disturb the ionosphere, the charged layer of Earth\u2019s upper atmosphere, and affect the radio signals sent down from satellites.<\/p>\n

GUARDIAN uses data from more than 350 continuously operating ground stations that receive signals from GPS and other Global Navigation Satellite System (GNSS) satellites. While normal GNSS processing filters out those distortions, GUARDIAN looks for them as evidence of tsunami activity.<\/p>\n

By analyzing these signals, the system can detect tsunamis as far as 1,200 kilometers (745 miles) from a station. In ideal situations, JPL says coastal communities could get as much as one hour and 20 minutes of advance warning. The Kamchatka quake provided the system\u2019s first real-world challenge just one day after JPL engineers deployed two major upgrades: an artificial intelligence (AI) model trained to spot tsunami-related signals and a prototype alert messaging system.<\/p>\n

When the tsunami pressure waves reached the upper atmosphere, GUARDIAN flagged the disturbance and notified human experts for review. Within about 10 minutes of receiving the raw data, the system produced a snapshot showing the atmospheric signal from the waves.<\/p>\n

How The System Could Protect Travelers In Coastal Regions<\/p>\n

Current tsunami warning systems rely on seismic data to estimate whether an undersea quake could produce a tsunami, and on deep-ocean pressure sensors to confirm if one is underway. Those sensors are considered the \u201cgold standard,\u201d but they are expensive and sparse.<\/p>\n

\u201cNASA\u2019s GUARDIAN can help fill the gaps,\u201d said Christopher Moore, director of the National Oceanic and Atmospheric Administration\u2019s Center for Tsunami Research. \u201cIt provides one more piece of information, one more valuable data point, that can help us determine, yes, we need to make the call to evacuate.\u201d Moore added that GUARDIAN offers \u201ca unique perspective\u201d by sensing sea-surface motion from high above the planet in near real time.<\/p>\n

Adrienne Moseley, co-director of the Joint Australian Tsunami Warning Centre, emphasized the importance of sharing GUARDIAN\u2019s data. \u201cTsunamis don\u2019t respect national boundaries. We need to be able to share data around the whole region to be able to make assessments about the threat for all exposed coastlines,\u201d she said. \u201cGUARDIAN has real potential to help by providing open access to this data.\u201d<\/p>\n
