【Abstract】 The detecting active faults is necessary for estimation of safety affected by possible earthquake and for architectural engineering. Therefore,it is important to choose a better geophysical method for the detecting work. The authors applied some geophysical methods, including the electric section,seismic reflection,GPR,and the measure of fault gas,for studying the fault structures causing earthquake in the coal-bearing basin of the Hunchun earthquake zone,and got good results. We found that the measure of fault gas is a simple,fast,credible and economic method used for detecting buried faults in the places excepting for the watered and paddy areas,among the geophysical methods applied.更多还原
