摘要
本文叙述了1695年临汾大震前的地震活动背景。分析了这次大震前的地震活动图象。指出16~17世纪是华北强震活动的全盛时期,而山西地震带的强震活动发生在这一时期的中后期,1695年临汾大地震是一系列7级以上强震中的最后一个,其孕育过程处在华北强震活动由“密集”转为“平静”的转折时期,认为1642年平陆6级地震是1695年临汾大地震的广义前震。
The paper outlines the seismicity background before 1695 Linfen macroquake,analyzes the seismicitypattern before the macroquak,suggests that the 16th~17th century was a strong seismicity peak period inNorth China,the strong earthquakes of Shanxi seismic zone occurred at medium-later stage of the strongseismicity peak period, the 1695 Linfen macroquake was the last one of a series of earthquakes with M≥7.0,its preparation process occurred at the turning stage from the closed activity to the quiescence of the medium-strong earthquakes in the strong seismicity peak period in North China, takes the 1642 Pinglu earthquakewith M6 0 for the generalized foreshock of 1695 Linfen macroquake.
