搜集公元19世纪前晋北地区地震活动若干资料,对其进行统计及时空特征分析。研究表明:公元前～公元399年、700～999年、1100～1299年地震活动记录较少,400～699年、1000～1099年、1300～1499年地震活动记录较多,1500年之后地震活动表现活跃,受地震影响的区域较广。地震空间分布主要集中在北西、东西方向展布的地震活动带上,多发生在一系列断陷盆地的边界。晋北地震活动多发生在夏四、六月份,秋冬九、十、十一、十二月份,一、七、八月相对较少。经分析发现,地震活动与其前后干旱灾害有一定相关性。讨论典型地震活动个案,对其震中、震级、烈度等问题做一定程度的恢复,并讨论地震所造成的严重影响及政府相应的减灾救灾措施和效果。
We collected some information about the seismic activity in the North of Shanxi before the 19th century AD and analyzed the statistics and the temporal and spatial characteristics. The results show that there are few records of earthquakes between the year of 399 BC, the period of 700 ~ 999 and the period of 1100 ~ 1299 BC. There are many records of earthquakes in 400 ~ 699, 1000 ~ 1099 and 1300 ~ 1499. After 1500 years of earthquakes Active, affected by the earthquake in a wider area. The spatial distribution of the earthquakes is mainly concentrated in the seismic activity belt distributed in the northwest and east-west directions, mostly occurring at the boundary of a series of fault basins. Earthquakes in the north of Shanxi Province occurred mostly in the summer, June and autumn, autumn, winter, September, October, November and December, with relatively few in January, July and August. According to the analysis, it is found that there is a certain correlation between seismicity and drought before and after it. Typical cases of seismic activity are discussed, and their quakes, magnitude and intensity are restored to some extent. The serious impacts caused by the earthquake and the government’s measures and effects of disaster reduction and relief are discussed.
