Researchers from the Institut de Physique du Globe de Paris and GFZ Helmholtz Centre have created a Jerk detection method that identifies subtle ground movements from magma intrusions using a single broadband seismometer. Tested over a decade at Piton de la Fournaise on La Réunion, the system forecasted 92% of 24 eruptions between 2014 and 2023, providing warnings from minutes to eight hours ahead. About 14% of alerts detected magma movements without resulting eruptions.
