Abstract

Recent studies of known lightning impacts and laboratory testing of samples from a suspected lightning-induced anomaly appearing in magnetic survey data allow us to characterize these formerly enigmatic responses. Remanent magnetization associated with the current path of a lightning discharge produces strong anomalies that can be recognized in magnetic survey data, and can be identified positively using laboratory methods.
