黑龙江及周边地区中强地震前加卸载响应比特征分析
Load / unload response ratio(LURR) characteristics analysis before the moderately strong earthquakes in Heilongjiang and its surrounding area
【摘要】 选取所研究区域地震能量的贝尼奥夫应变(相当于室内岩石实验中的声发射)作为响应,以黑龙江及其周边地区2005年以来14次ML 5.0以上地震作为震例,检验卸载响应比理论的预测效果,提取异常特征,初步总结该方法的时、空、强预测指标,发现具有一定的预报效能。
【Abstract】 Load / unload response ratio theory is a new earthquake prediction method that has been accepted by more and more seismologists worldwide, but the theory has its own characteristics in different regions because of different geological settings. We choose the seismic energy E in study area as a response and 14 ML≥ 5.0 earthquakes in Heilongjiang and its surrounding area since 2005 as examples, and test the ability of response ratio theory, then we extract abnormal characteristics, and preliminary summarize prediction index, finally, we find this method has the certain prediction efficiency.
【Key words】 earthquake prediction; load /unload response ratio(LURR); spatial scanning; prediction index;
