Analysis of seismic response of Suqian Fault Gas Network
摘要
Abstract
Using methods such as linear fitting and correlation analysis,this study systematically examines the variations in fault gas measurements and seismic response characteristics at 10 observation stations of the Suqian Fault Gas Network before and after earthquakes.The analysis is based on the temporal evolution of radon,hydrogen,and carbon dioxide concentration curves,the spatial relationship between concentration intensity changes and seismogenic faults,as well as the depth-dependent content variations of different fluid components.The results indicate that the measured values of radon,hydrogen,and carbon dioxide from the network exhibit significant abrupt changes before and after seismic events,with gas concentrations showing a regular enhancement response.These findings provide meaningful indicators for determining the timing and location of earthquakes,offering important scientific support for seismic monitoring and anomaly verification along the Suqian segment of the Tanlu fault zone.关键词
