摘要
分析了1991年3月26日大同—阳高5.8Ms地震与1989年10月大同—阳高6.1Ms震群的关系,认为这两次地震属于同一类震群.介绍了这次地震前赤城台石英摆倾斜仪、太原台目视水管倾斜仪和阳原台金属摆倾斜仪的异常情况.从两次地壳形变异常的异同映证了两次地震属同一震群.同时也说明利用地壳形变资料预报地震是有希望的.
The relationship between the Ms 5- 8 earthquake on March 26,1991 and the Ms 6.1 earthquake of October,
1989 in Datong-Yanggao are analyzed, and the anomalies of the Quartz pendulum tiltmeter at Chicheng sta
tion, the water-tubetilt-meter at Taiyuan station and the metal pendulum tiltmeter at Yangyuan station before
the earthquakes are described. The differents and similarities among the two earthquakes show that the two
earthquakes belong in same swarm, and the earthquake prediction using the crustal deformation data is hopeful.
