Short summary

We report significant evidence for pre-seismic ionospheric anomalies in total electron content (TEC) of a global ionosphere map (GIM) and plasma density and temperature appearing on day 2 before the 17 July 2006 M7.7 south of Java earthquake. The LTT spatial analysis also reveals a new feature: the TECs on epicenter side anomalously decrease and lead to an anomalous asymmetric structure with respect to the magnetic equator starting from day 2 before and disappearing after the earthquake.
