DISTURBANCES OF LOWER IONOSPHERE ABOVE CENTER OF EARTHQUAKE AND ANOMALY IN THE GLOBAL ELECTROMAGNETIC RESONANCE SIGNAL PART 1. MODELS OF IONOSPHERE [PDF]

open access: yesРадиофизика и электроника, 2015
We model an effect on the Schumann resonance signal recorded in Japan of the ionosphere non-uniformity centered above the earthquake at Taiwan. Changes in the resonance spectrum occur due to interference of the direct radio wave with one reflected from ...
