| Abstract: | Using the technology of ionospheric tomography, three??dimensional ionospheric electronic density maps from April 1??st?? to 15??th?? in 2012 were reconstructed near the epicenter of Sumatra, The electron density anomaly detection is based on the doubled standard deviation. After excluding the solar activity and geomagnetic disturbance, the abnormal ionospheric electron density happened at the UT 10:00 on 11??th??, UT 6:00 on 13??th??, UT 6:00??14:00 on 14??th??, UT 14:00??16??00 on 15??th??, and they distributed mainly near the epicenter. The anomalies are likely a premise of the Sumatra earthquake in April. |
