An innovative system for seeing into the bowels of a volcano
A team of researchers from the CNRS and the Paris Institute of Planetary 萌妹社区ics has developed an innovative imaging method that can probe the bowels of a volcano with unparalleled resolution and depth. This new method is based on the deployment of a network of geophones that capture not only the powerful shaking of earthquakes, but also the seismic noise caused by wind, the ocean, and human activity.
Their study was conducted on La Soufri猫re volcano in Guadeloupe, and provided a 3D view of its internal structure to a depth of 10 kilometers, with a precision on the order of 100 meters. It confirmed the existence, in the depths beneath La Soufri猫re, of a large magma storage zone structured by a network of interconnected magma pockets.
This imaging tool can be applied to any geophone network and could record volcanic activity much more thoroughly, thereby providing greater anticipation of volcanic eruptions throughout the world.
