The study of higher frequency seismogenic EM emissions based on theobservation results of “Kobe earthquake”

摘要

For the Kobe earthquake, many higher frequency seismogenic EMemissions were observed in the MF, HF and VHF bands. From ourinvestigation, the exciting energy is transferred by impulsive magneticfields from the focus to the epicenter area. The excited higherfrequency electromagnetic waves at a highly conductive slot consisted ofa slit antenna along the fault zone
