Web1 feb. 2011 · [1] This paper presents a statistical study of the pre-earthquake ionospheric anomaly by using the total electron content (TEC) data from the global ionosphere map. A total of 736 M ≥ 6.0 earthquakes in the global area during 2002–2010 are selected. The anomaly day is first defined. WebFirst, we assume that potentially anomalous (stormy) mid-latitude ionospheric conditions are limited to periods with Kp indices equal to or larger than 5, while anomalies on periods with Kp indices less than 5 are extremely unlikely to create threatening gradients for GBAS.
