DISTURBANCES OF LOWER IONOSPHERE ABOVE THE CENTER OF EARTHQUAKE AND ANOMALY IN THE GLOBAL ELECTROMAGNETIC RESONANCE SIGNAL PART 2. ANOMALIES IN THE POWER SPECTRA

Abstract

We model an effect of the ionosphere non-uniformity centered above the earthquake at Taiwan on the Schumann resonance records in Japan. The changes in the resonance spectra arise from the interference of the direct radio wave with the one reflected from the ionosphere modification above the earthquake. The disturbance model is used and it was described in the first part of this work. Solution of the Stratton-Chu integral equation is used for describing the wave diffraction and scattering. Observations of the Optical Transient Detector (OTD) satellite are used for modeling the spatial distribution of global thunderstorms. Computations showed that abrupt changes occur in the spectra of all field components resembling the observational results. The features of seismogenic anomalies are discussed.
