摘要
基于河南省豫北地区跨断层形变观测资料,在排除观测时段相关干扰的基础上,选取2002—2019年观测场地周边200 km范围内中等强度地震,依据震例对应规则,使用不同类别异常提取方法进行预报方法的检验和效能评估,并通过对比分析R值检验结果,总结适用于该地区跨断层形变观测的最佳预报方法。
Based on cross-fault observation of mobile crustal deformation in the Northern Henan area,after eliminating related interference in the observation period,we selected moderate strong earthquakes 200 km within the observation site-and used different kinds of anomaly extraction methods to conduct forecast method effectiveness evaluation according to earthquake case correspondence rules.And then,we summed up the best forecast methods suitable for this cross-fault area through a comparative analysis of R-value test results.
