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.

Researchers have determined that a unusual gravity hole beneath Antarctica formed due to slow movements of rock deep inside Earth over millions of years. The anomaly strengthened between 50 and 30 million years ago, coinciding with changes in the continent's climate. This discovery provides insights into how Earth's interior influences surface conditions like sea levels and ice sheets.
