Abstract The present research deals with the study of soil electrical conductivity as an earthquake precursor along the Margalla fault line and its correlation with the increase in temperature due to global warming. Moreover, comparative study to analyze correlation of EC with physico chemical properties of soil like moisture content, pH, temperature and texture has been conducted. This correlation can help in short term probabilistic analysis of earthquakes with accuracy and without bias because many inter related properties have also been taken into account. Thus, analyses were conducted by collecting soil samples through incremental sampling technique and analyzing by laboratory methods including electrical meters for pH and EC and hydrometer for soil texture analysis. Results suggest that EC and temperature have a negative correlation which means that increase in temperature results in decline in soil EC along the studied fault line. Also, low temperature can increase the EC of soil, which can assist in developing a probabilistic seismic hazard analysis in the area in context of the electrical conductivity as a short term precursor to earthquakes.

季节性变化对土壤电导率的影响作为伊斯兰堡 Margalla 断层线地震前兆

摘要 目前的研究涉及土壤电导率作为沿 Margalla 断层线地震前兆的研究及其与全球变暖导致的温度升高的相关性。此外，还进行了比较研究，以分析 EC 与土壤理化性质（如水分含量、pH 值、温度和质地）的相关性。由于还考虑了许多相互关联的属性，因此这种相关性有助于准确无偏差地进行短期地震概率分析。因此，通过增量采样技术收集土壤样品并通过实验室方法进行分析，包括测量 pH 值和 EC 的电表和用于土壤质地分析的比重计进行分析。结果表明，EC 和温度呈负相关，这意味着温度升高会导致沿研究断层线的土壤 EC 下降。此外，低温可以增加土壤的电导率，这有助于在电导率作为地震的短期前兆的情况下，在该地区开展概率地震危害分析。
