Earthquake signature related to Investigation of ELF/VLF signals observed by DEMETER satellite over Pre-seismic region
Abstract
Abstract: Phenomena of non-linear interaction and turbulence in the ionospheric plasma in VLF frequency range has been studied prior to the earthquake with magnitude M=7.0 on November 11, 2004 in Hokkaido region in Japan. It includes the disturbances of ionospheric electric field to the earthquake. Special attention is given to non-linear interaction and characteristics of the turbulence in the signals. Although the process of energy transfer form ground to upper atmosphere has not been determined. The results are in line and an extension of main fold research with regards of ionospheric activity during earthquake preparation process. Keyword: non-linear interaction, bicoherence, ionospheric plasma
