Geophysical Signatures for Underground Structures
Clandestine underground structures are a serious and growing global security threat. There is an urgent need for technology capable of reliably detecting and locating underground structures of various sizes and depths. Current detection capabilities rely on random tips and human intelligence. However, temporal changes in the subsurface structure have documented effects on geophysical observations through a variety of mechanisms at a range of scales. This project investigates a new and innovative joint analysis of existing geophysical datasets (seismic, gravity) to understand interactions between voids, the subsurface, and geophysics.
