From: Investigation of GIM-TEC disturbances before M ≥ 6.0 inland earthquakes during 2003–2017

Occurrence rates of the TEC disturbances appear within 1 day (a) and 5 days (b) before and after the earthquakes with different magnitudes. The red and blue colors denote TEC disturbances before EQs and after EQs, respectively. The solid lines denote the fitting curves.
