GPR in Volcanic Environments
See also: Introduction to GPR
GPR has become an increasingly popular tool for field-based volcanologists. Being able to map and characterise the three-dimensional internal stratigraphic/spatial variance of deposits, at metre-scale resolutions, is providing researchers with new insights into the emplacement process and dynamic controls that affect deposit formation.
GPR can be used to characterize the nature, geometry and spatial distribution of sub-surface volcanic materials and complement field observations, especially in those areas where information obtained from the surface is restricted due to poor exposure. Thanks to rapid data collection and the possibility to image large areas in short time scales, GPR has found application to a range of deposit types from welded ignimbrites to block-and-ash flows.
