Some volcanoes are like pressure cookers, but without a safety valve. The hydrothermal activity within can result in dangerously unpredictable hazards, like devastating laterally-directed explosions, or collapse of the volcanic edifice. Using novel tomographic imagining techniques, together with numerical simulations, Dr. Marina Rosas-Carbajal, of the Institut de Physique du Globe in Paris, aims to shed light on the subsurface dynamics at work in the La Soufrière de Guadeloupe volcano. The outcome of her research – a simple functional model to characterize the changes in the internal physical state of the volcano’s hydrothermal system –, will pave the way for a better assessment and mitigation of unpredictable volcanic hazards.
