霍山皖33井水位与“霍山窗”小震活动关系的初步研究
|
摘要
分析了霍山皖33井水位变化与"霍山窗"地震活动的关系:首先采用差分法和从属函数等方法对水位数据进行处理,提取了水位的短期异常,结果表明该井水位异常对霍山以及周边地区的中小地震有较好的反映;其次,通过对该井水位与"霍山窗"小震活动性的对比研究,发现该地区小地震在水位低值时活跃。参考该地区的环境剪应力,我们认为霍山皖33井水位变动与区域应力场变化有一定的准同步性。
The relationship between water level and activity of Huoshan seismic window was discussed in this paper.First,Short-term anomalies were extracted and analyzed by using first order difference and subordinate function.The results implied that anomalies of water level were related with the moderate and small earthquakes in the area of Huoshan and its neighbor regions.Then,the relationship of the change of water level and the earthquake activity in Huoshan seismic window was discussed.We found that the earthquakes were active when the water level was low.Comparing to tectonic ambient shear stress of this area,the change of water level in Huoshan 33 well may have some certain synchronicity with it.
