前言关于震中迁移现象已有不少人进行过研究。1966年郭增建等同志研究了甘肃和宁夏地区发生的破坏性地震的迁移规律,提出了可以把震中迁移现象作为地震预报的一种方法,並指出未来大震最可能是沿着原来的极震区长轴方向、弱震带延伸方向和发展构造延伸方向迁移。1966年邢台地震后,人们根据震中迁移预报过1967年河间6.3级地震和1975年海城7.3级地震。1980年郭增建、秦保燕同志编制了全国震中迁移略图,该图给出了中国大陆主要的地震迁移带。1981年在该图所给出的道孚至民丰迁移带上再次出现了破坏性地震的迁移
Preface There have been many studies on the phenomenon of epicenter migration. In 1966, Comrade Guo Zengjian and other comrades studied the migration of destructive earthquakes in Gansu and Ningxia and put forward the method of using the phenomenon of epicenter migration as a method of earthquake prediction. It is pointed out that the future major earthquakes are most likely to be along the original extreme earthquakes Long axis direction, weak earthquake zone extension direction and development structure extension direction migration. After the Xingtai earthquake in 1966, people predicted the 6.36 Hejian earthquake in 1967 and the 7.3 Haicheng earthquake in 1975 according to the epicentral migration. In 1980, Guo Zengjian and Qin Baoyan compiled a map of the national epicenter migration, which shows the major seismic migration zones in mainland China. In 1981, there was another reoccurrence of devastating earthquakes on the migration belt from Daofu to Minfeng given in the figure
