• Is an unusual large enhancement of ionospheric electron density linked with the 2008 great Wenchuan earthquake (2008, methodology): “modification as a whole structure and the most often observed effect is the equatorward shift of both crests of the EIA up to their complete disappearance [Pulinets and Boyarchuk, 2004; Liu et al., 2001 ].”
• A statistical analysis of ionospheric anomalies before 736 M6.0+ earthquakes during 2002-2010 (2011, unknown): “Thus the ionospheric anomalies before the earthquake near the epicenter are studied widely by many geophysicists and a number of papers have reported on deviations in the daily values of the critical frequency of the F2 layer (foF2) and/or total electron content (TEC) in the vicinity of an epicenter”
• Seismoionospheric GPS total electron content anomalies observed before the 12 May 2008 Mw7.9 Wenchuan earthquake (2009, background): “notably decreased 3–4 days before the earthquake [Liu et al., 2001].”
• Ionosphere plasma bubbles and density variations induced by pre‐earthquake rock currents and associated surface charges (2011, background): “Additional pre‐earthquake ionospheric signatures have been reported that include ground and satellite‐ measured electromagnetic perturbations [Park et al., 1993; Parrot et al., 1993; Bhattacharya et al., 2009], ionosonde‐ recorded variations of fo F2 [Liu et al., 2000; Chuo et al., 2001; Silina et a”
• Pre-earthquake ionospheric anomalies registered by continuous GPS TEC measurements (2004, unknown): “In this paper, we adopt the procedure of Liu et al. (2001) to derive the GPS TEC and then employ the statistical analysis of Liu et al. (2000) to identify possible pre-earthquake ionospheric anomalies 15 days before and after each of the 20 M > = 6.0 earthquakes in the Taiwan area from September…”
• An improved coupling model for the lithosphere‐atmosphere‐ionosphere system (2014, background): “The related ground-based observations of earthquake precursors were reported in the literatures, which includes ionospheric sounding [Liu et al., 2001; Pulinets and Boyarchuk, 2004; Liu et al., 2009], DC electric field emissions/ULF/VHF [Varotsos, 2006; Schekotov et al., 2007; Smirnova and…”
• A statistical investigation of preearthquake ionospheric anomaly (2006, background): “For example, Liu et al. [2000, 2001] observed anomalous reductions of the plasma frequency at the peak of the ionospheric F2 region foF2 and of the ionospheric total electron content (TEC) around the epicenter 1, 3, and 4 days before the Chi-Chi earthquake (occurred on 21 September 1999 in local t”
