Ionospheric disturbances around the time of the Ms7.0 Lushan earthquake

Variations of Vertical Total Electron Content (VTEC) in the ionosphere are investigated around the time of the Ms7.0 Lushan earthquake A time-series analysis shows an anomalous VTEC increase 15 days before, as well as some anomalous VTEC decreases 5 days before and 8 hours after the earthquake.Each of these anomalies lasted more than 4 hours and drifted from east to west.The anomalous increase 15 days before the earthquake is significantly larger than the solar-terrestrial background noise, and is thus considered to be probably related to the earthquake..
