Abstract:
|
It's a beneficial supplement for ground study to use electromagnetic satellite to study the relation between earthquake and the transformation of electromagnetic field of space ionosphere and magnetosphere. This becomes a new study direction for studying theory and forecast of earthquake, in which studying the related speciality of space electriferous particles is an important content. We analyzed the data close-by Wenchuan earthquake (May 12, 2008) and the 2008 data detected by IDP, which was installed on board of the DEMETER satellite, developed by France. The electron drift in the inner radiation belt, the variation of the electron energy spectrum at different area including that of Wenchuan and the relation of the space electron flux and the aftershock in Wenchuan area were studied. We found that the spectrum at 90~600 keV energy range in the area (90°E ~110°E,47°N~49°N) on May 12 is obviously different from that of several days before and after. The low energy range spectrum at the VLF electron belt rised several days before the earthquake. |
