摘      要：The seismo-ionospheric anomalies may provide some insights about the ***,preseismic ionospheric anomalies are still *** this paper,seismo-ionospheric anomalies are investigated before the September 24,2013(Mw=7.7)Awaran(Pakistan)earthquake from GPS TEC(Total Electron Content)and COSMIC(Constellation Observing System for Meteorology,Ionosphere and Climate)*** TEC data are showing anomalies on September 21,*** abnormality detected in the temporal data is about 10 TECU beyond the 30-day running *** percentage deviation of the TEC anomaly on September 21,is 30% above the upper confidence *** anomalies prevail 5 in Latitude and 10 in Longitude over the *** spatial and temporal data of TEC showed anomalies in TEC from UT=08 to UT=*** addition,the enhancement on September 21,2013 is also very significant in COSMIC *** results of COSMIC completely agreed with GPS TEC anomalies on September 21,*** percentage deviation of the peak plasma frequency on September 21 is 5% of the normal *** storm indices are quiet before and after the *** pre-sesimic ionospheric anomalies are most probably associated with the 2013 Mw=7.7 Awaran(Pakistan)earthquake.
