Abstract

By employing the cross-correlogram method, in geo-electric data from the area of Kyrgyzstan for the period 30 June 2014-10 June 2015, we identified Anomalous Telluric Currents (ATC). From a total of 32 ATC after taking into consideration the electric current source properties, we found that three of them are possible Seismic Electric Signal (SES) activities. These three SES activities are likely to be linked with three local seismic events. Finally, by studying the corresponding recordings when a DC alternating source injects current into the Earth, we found that the subsurface resistivity seems to be reduced before one of these three earthquakes, but a similar analysis for the other two cannot be done due to their large epicentral distance and the lack of data.

摘要

通过采用互相关图法，对吉尔吉斯斯坦地区2014年6月30日至2015年6月10日期间的地电数据进行分析，我们识别出了异常大地电流（ATC）。在考虑电流源特性后，从总共32个ATC中，我们发现其中三个可能是地震电信号（SES）活动。这三个SES活动可能与三次当地地震事件有关。最后，通过研究直流交流电源向地球注入电流时的相应记录，我们发现这三次地震中的一次发生前地下电阻率似乎降低了，但由于另外两次地震震中距较大且缺乏数据，无法对其进行类似分析。
