ECRS方法在河北及周边地区的应用研究
The application of ECRS methods in Hebei Province and around area
摘要
Abstract
Applying the Earthquake Corresponding Relevancy Spectrum (ECRS) method, the three research of Hebei and surrounding area before moderate strong earthquakes in various seis-mological parameter synthetic characteristic of anomalies were quantitatively recognized. At the same time, the application of the method of dynamic prediction for many years and performance test. The results show that, at present the MSER in the margin region of Shanxi, Hebei provinces and Inner Mongulia autonomous region and in the margin region of Shanxi, Hebei, Shandong and Henan provinces is not obviously abnormal, but the MSER in Tangs-han area since the second half of 2010 appears high value anomaly. From 2002 to 2011 year after year dynamic extrapolation forecast test, the forecast accurate rate of this method in the margin region of Shanxi, Hebei, Shandong and Henan provinces and Tangshan area is 56%. Dynamic extend forecast avoids to use the data after the earthquake reverse contribution to the prediction before the earthquake. The method could be more significance for the earthquake prediction practice.关键词
