Science Cafe: Monitoring Volcanoes from Space
November 21, 2017 @ 7:00 pm - 8:00 pm
Dr. Hélène Le Mévelis is a Staff Scientist at the Carnegie Institution for Science in Washington DC. She obtained her PhD in Geophysics at the University of Wisconsin-Madison in 2016. Her research combines analysis of ground and space-based geodetic data with computational modeling to understand how active volcanoes deform, the goal being to better understand eruption precursors.
Remote sensing techniques have allowed us to detect small-scale surface deformation at volcanoes around the globe and revealed that most volcanoes experience cycles of ground motion (uplift and subsidence). How do we measure centimeter-scale ground deformations from space? What does it tell us about the volcano? How can we relate the ground deformation to magmatic processes taking place in the Earth’s crust? Can we use those data sets to help monitor active volcanoes?
