  Information - GMPV21 Understanding Physical and Chemical Signals at Active Volcanoes

Event Information
Magmatic and hydrothermal processes at active volcanoes involve the migration of multiphase fluids at depth, and their dynamic coupling with the hosting rock. Such movements are identified at the surface in terms of variations in geophysical and geochemical parameters, and the understanding of such changes is critical for the prompt identification of volcanic unrest. Recent technological advances allow for detection of multiple signals over broad temporal scales, thus opening new avenues to the multi-disciplinary interpretation of subsurface mass migration and fluid-rock interaction. We invite contributions that integrate geophysical and geochemical data in the investigation of either quiescent or eruptive stages at active volcanoes. We particularly welcome contributions that demonstrate clear linkages between seismicity, degassing, ground deformation and gravity time series. Results from forward numerical models of fluid-dynamics and fluid-rock interactions are equally welcome.
