河北省地震构造
SEISMIC STRUCTURE OF HEBEI PROVINCE
-
摘要: 河北省是一个强震多发地区。著名的阴山、燕山地震带和华北平原地震带位于本区。区内发生过1679年三河、平谷8级地震,1830年磁县7(1/2)级地震等。自从1966年邢台6.8级和7.2级地震发生以来,又发生过1967年河间6.3级地震,1976年唐山7.8级地震、滦县7.1级、宁河6.9级地震等。Abstract: Four aspects of seismic structure of Hebei province were analysed,that is, (1)seismicity of Hebei province,(2)Cenozoic geotectonic framework,(3) neo-geotectonic movement and(4)recent geotectonic movement.
The authors have mainly discussed the characteristics of the earthquake spatial and temporal distribution and its migration in NS direction in the first aspect;the Cenozoicsedimentaton,downfaulted bosin,seismic subareas divided by different structures and deep-seated structure in the second;the structural stress field,active fault,fold and activity of volcano and hot spring in the third;the changes of river system in plain areas,focal mechanism,ground deformation in the fourth.Finally,fundamental characteristics of seismic structure of Hebei province were summed up. -
