• Electron and ion density variations before strong earthquakes (M>6.0) using DEMETER and GPS data (2010, methodology): “Zhao et al. (2008) observed the anomalous enhancement of the seismo-ionospheric electron content 3 days prior to 12 May Sichuan earthquake using TEC variations.”
• 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”
• Ionosphere plasma bubbles and density variations induced by pre‐earthquake rock currents and associated surface charges (2011, background): “…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 al., 2001], and GPS‐measured TEC [Liu et al., 2001; Zhao et al., 2008; Liu et al., 2009].”
• An improved coupling model for the lithosphere‐atmosphere‐ionosphere system (2014, background): “…TEC (total electron content) variations before strong earthquakes [Liu et al., 2000; Liu et al., 2001; Chuo, 2002; Pulinets and Legen’ka, 2003; Liu et al., 2004; Zhao et al., 2008; Liu et al., 2009; Liu et al., 2010; Klimenko et al., 2011; Zolotov et al., 2011; Heki, 2011; Namgaladze et al., 2012].”
