The shallow deformation through active Huangzhuang-Gaoliying fault near Lishuiqiao in Beijing urban area was investigated with high-resolution seismic exploration. The results indicate that there exists structure of three layers at the shallow part of the area, and the active fault consists of many concealed faults which remain active at present. There are multi-subsidence centers on the hanging wall of the fault which are characterized by different locations and different subsidence ranges in different periods. Lots of small faults were produced beside these subsidence centers. According to these characteristics, the activity of Huangzhuang-Gaoliying Fault can be studied reliably.
