| Abstract: | According to the features of litho-geologic body and its response to earthquake the study of anomalous areas of high intensity nearby Beijing caused by the Tangshan earthquake is carried out in this report. It is suggested that the "anomalous areas" may be regarded as a loose geologic unit formed under the conditions of lithologic alternation and mainly consisted of fine sand and silt interbedding structure or of clayey fine sand intercalated with silt.The coefficient of rigidity of each unit is |
