| Abstract: | Changjiang fault zone, also called Mufushang-Jiaoshan fault, is a famous fault that is located at the southern bank of the Changjiang river around Nanjing downtown area. Striking in about east-west orientation with the north trending, this fault is near 100km long and is featured by normal fault mode. At both ends of the fault, there occurred earthquakes with magnitude of 5-6 in the past. Based on the analysis from shallow artificial seismic exploration, trough study, drilling exploration and application of dating techniques, this paper provides the most-up-to-date results regarding to the activity of Changjiang fault, such as most recent active time, faulting mode, the related active parameters and relation to the seismic activity. |
