| Abstract: | Based on summarizing and describing the abnormal variations of gravity data before the Datong Yang-gao earthquake on october 1 8,1 989 from 4 stations,the principal features of gravity precursors of this earth-quake have been analyzed,and the variations of gravity field have been discussed using the deformation dataand seismostructure,The conclusion that above mentioned variations may relate to seismostructure activity isobtained. |
