THE SHALLOW SEISMIC METHOD FOR DETECTING CITY FAULT ACTIVITY
Guanjun Liu · Geophysical and Geochemical Exploration · 2007
The seismic method is an important exploration method for detecting active faults buried directly beneath major cities.Different array lengths must be adopted for different detecting depths.Test results show that small group interval receiving can help to determine accurately the space position of faults,determine the buried depth of the upper terminal points of active faults,and contribute to improving comprehensively vertical and horizontal resolution of seismic records.This paper discusses some problems concerning the detection of city active faults by using shallow seismic reflection on the basis of the results of shallow seismic reflection processing for Xiadian active fault in Beijing.
