| 摘 要： | 东濮拗陷位于河北平原地震带东南部，南邻河淮地震带，东与郯庐地震带相望。东濮拗陷受控于新北东向的聊兰断裂、黄河断裂和长垣断裂，对该区的地质构造特征、地震特征、震相特征等进行了研究。指出，东濮拗陷区的地震属浅源地震，该区有康氏面存在，地震台可记到清晰的康氏面反射波P^＊。

| Abstract: | Dongpu depression is located at the southeast of Pingyuan,Hebei,seismic belt,which is adjacent to Hehuai seismic belt in south and opposite to Tanlu seismic belt in east. Dongpu depression is controlled by the NE Liaolan fault, Huanghe fault and Changyuan fault. Seismicity of this area increases dramatically in recent years. After studying the geologic tectonic characteristic, earthquake characteristic and seismic phase characteristic of this area, the author points out that the earthquakes in Dongpu depression belong to shallow-focus ones. There is Conrad discontinuity in this area and reflected wave P of Conrad discontinuity can be clearly observed at seismological stations. |
