One Sensor, Big Forecast: The Jerk System Predicts Eruptions Automatically

A decade-long study of the Jerk system—an automated, single-station seismometer near Piton de la Fournaise—accurately predicted about 92% of eruptions, issuing alerts minutes to eight hours before surface activity and validating 24 eruptions. Researchers aim to test the approach on Mount Etna, reduce false positives, and expand with multiple stations and deeper boreholes to generalize the method.
