Assisting volcanic eruptions’ monitoring from space using SAR imagery

The goal of this work is to develop a method capable of tracking topographic changes at the surface of an erupting volcano in near-real time. The method should allow to estimate quantitatively the position and the geometry of structures (e.g. cones, craters, domes) forming during the eruption in order to know their volumes and the evolution of these volumes with time (discharge rates), as well as their growth dynamics (velocity field). To track these topographic changes during both day- and night-time, no matter the meteorological conditions (cloud cover, eruptive plume), the method relies on the use of satellite radar (SAR) images.
