AI Can Spot Early Signs of a Tsunami from Atmospheric Shock Waves
A truly effective tsunami detection system would require international cooperation to share data from satellite constellations.

Researchers at Florida-based satellite manufacturing company Terran Orbital Corp. found that off-the-shelf artificial intelligence (AI) models can detect the early signs of a tsunami in two-dimensional (2D) images from GPS satellites.
The researchers used data generated by a computer algorithm developed by researchers at NASA's Jet Propulsion Laboratory and Italy's Sapienza University of Rome, which measures changes in the density of charged particles in the ionosphere as tsunamis form.
The data was transformed into 2D images that were analyzed by the AI to identify features associated with tsunamis.
The AI achieved a reported detection performance rate above 90% after eliminating ionospheric disturbance patterns that at least 70% of ground stations in contact with the satellites failed to pick up.
