Predicting a volcanic eruption eight hours earlier than turns into potential | EUROtoday

The alert was issued at 5:03 p.m. on January 18. That day, the scientist on responsibility on the Piton de la Fournaise Volcanological Observatory (OVPF-IPGP), in Reunion, acquired a voice alert message informing him that the present seismic disaster can be adopted by an eruption, as a result of the Rivière de l’Est (RER) seismic station had detected a excessive depth “jerk” sign. Two hours and forty-five minutes later, at 7:48 p.m., one of many webcams positioned on the sting of the Enclos Fouqué despatched photographs of the primary lava fountain. Delighting the locals, who’re keen on this type of spectacle. And bringing new satisfaction to François Beauducel, from the Paris Institute of Globe Physics (IPGP), delighted to have reached, for the 25^e consecutive occasions, to foretell the phenomenon.

With a couple of colleagues from the IPGP and the German Earth Sciences Research Center (GFZ Helmholtz), this geophysicist launched into an bold venture: detecting sure precursor alerts of volcanic eruptions. The outcomes of their analysis, printed in December 2025 within the journal Nature Communications, permit, they write, to anticipate magma rises as much as eight and a half hours upfront, i.e. adequate time to place in place safeguard measures for populations.
