DECRYPTION – French scientists have succeeded in reconstructing the underground structure of Soufrière using a high-resolution imaging technique that could be used to predict eruptions.
No device had previously made it possible to explore the bowels of a volcano with such high resolution. Thanks to a new imaging technique, researchers from the Langevin Institute and the Institute of Globe Physics have detailedly mapped the internal structure of the Soufrière volcano, in Guadeloupe, with a margin of error of only Close to 100 meters. A technical feat that competes with conventional approaches.
By revealing the various magmatic conduits, previously unexplored, of this active volcano, the researchers believe that this approach would make it possible to obtain a better understanding of the functioning of volcanism, and even to better anticipate possible eruptions. The results appeared in Nature Communications Earth & Environment.

To make the “ultrasound” of the volcano, the researchers used a technique called raster imaging. They “listened” to the seismic sounds…
