日本MW9.0地震前电离层异常初步分析

Abstract

Abstract: A 9.0-magnitude (M_W) earthquake struck off the coast of northeast Japan on 11 March 2011. On the basis of the GPS data from IGS (International GPS Service) and Japan's GPS observation networks, we got the 20 days' time series of the ionosphere vertical total electron content (VTEC) over the epicenter before this earthquake. To detect abnormal signal of TEC variation, a sliding quartile-based (before 15 days) process is performed. Meanwhile occultation data from FORMOSAT3/COSMIC are used in order to analyze the pre-earthquake profile of electron density and understand the variations of the F₂ peak electron density (N_mF₂) and the peak height (h_mF₂). Preliminary results demonstrate that ionospheric parameters begin to increase a week before the earthquake. Combined with the solar and Geo-magnetic activities, we suggest that the abnormal variation of the ionospheric parameters may result from the earthquake.

Key words: Ionospheric anomaly, VTEC, Electron density profile, Earthquake precursor, the Great East Japan Earthquake
