NS44A:
Near-Surface Geophysics and Its Applicability to Volcanic Environments I


Submit an Abstract to this Session


Session ID#: 56877

Session Description:
Volcanic environments present interesting geophysical challenges. The complex terrain and inherently 3D subsurface require advanced near-surface geophysical data acquisition and modeling, for example, to account for high surface electrical resistivities or excessive seismic scattering. Due to complexities at various spatial scales, geophysical method diversity and multi-physics approaches are key for successful characterization. Volcanic environments potentially offer geothermal resources. Acquiring a plurality of geophysical data types can help assess the geothermal potential. Volcanic geology can impact hydrology tremendously (e.g. dikes, chemical alteration, fractures); improving hydrological models requires hydrogeophysical data. Depending on the setting, volcanoes may be covered by glaciers or experience permafrost conditions, adding complexity to their geophysical characterization. We invite contributions covering all aspects of near-surface geophysics, including theory, laboratory experiments, modeling, inversion, field experiments, equipment, as well as hydrological and geothermal applications. We would like the contributions to demonstrate a connection, or discussion of the applicability, to volcanic environments.
