AB We model impact of the ionosphere disturbance centered above the earthquake at Taiwan on the
electric and magnetic Schumann resonance records in Japan. Changes in the resonance spectra
arise from the interference of the direct radio wave with the wave reflected from the ionosphere
modification above the earthquake. The disturbance model is used that 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.
