Minimizing Epistemic Uncertainty in Refraction Inversion with the GRM

Refraction tomography is widely employed to invert seismic refraction data recorded for geotechnical and environmental investigations. However, refraction tomography is inherently non-unique: an infinite number of solutions can satisfy a given set of data. This study demonstrates that nonuniqueness in the inversion of near-surface seismic refraction data can be explicitly addressed with the generalized reciprocal method (GRM) [1].
