| 英文摘要 | Using GPS TEC data, we have statistically analyzed the ionospheric perturbations prior to the M-s >= 6. 0 earthquakes in China main land from November 1st, 1998 to December 31st, 2010. The obtained results indicated that the GPS TEC had the same variation trend above the epicenter and eastern, southern, western, northern directions 15 days before earthquakes, and decrease occurred in all the 5 directions from 3 days to 5 days. Through different space scale analysis of +/- 10 degrees, +/- 20 degrees, +/- 30 degrees, it was found that the maximum seismoionospheric disturbance didn't appear just above the epicenter, but shifted to the magnetic equator, and it was worth to point out that the affected region in ionosphere was about +/- 15 degrees. Besides this, prior to earthquakes, positive anomalies appeared in the southwestern direction before 14th, 10th days, and there were obviously negative anomalies in the southeastern direction before 5th day. At last, a hypothesis of electrostatic field channel in lithosphere-atmosphere-ionosphere coupling was used to explain the observed phenomena. |
