Abstract

When does a subsurface geologic “situation” become a geohazard? Slope failures, strain release, and sinkhole collapses, for example, occur on a daily basis. When these occur in close proximity to a population center or some infrastructural component (e.g., a dam, a sports arena, a highway) and threaten the life, livelihood, or ability to conduct work or function in normal societal fashion, then these are aptly termed “geohazards.” Given these attributes, the greatest diversity and number of searches for geohazards are going to be conducted in urban settings. Application of geophysics and interpreting potential geohazards, then, does not have the luxury of study sites where the target is the only potential anomaly that will or could be observed.
