Abstract:
Volcanic eruptions are driven by the exsolution and expansion of gases dissolved within magma as it ascends to the surface. The magnitude and composition of these emissions reflects the state of the magmatic system, providing a useful tool to monitor volcanic eruptions and investigate volcanic processes. Satellite instruments can detect and quantify volcanic gas emissions, primarily of sulphur dioxide (SO2), on a global scale, with recent advances in instrumentation and data processing opening the possibility to monitor even effusive emissions low in the atmosphere and in near real-time.
In this seminar we will explore results from several recent volcanic eruptions of note, combining SO2 imagery from ESA’s Tropospheric Monitoring Instrument (TROPOMI) with global meteorological models to obtain continuous, sub-daily emission rates. This allows us to directly compare with other monitoring datasets, including deformation, seismic and thermal data, providing an ever-deeper insight into the eruption dynamics
