| Abstract: | Using the mechanism solutions of the strong and medium-small earthquakes in the Red-River Fault Zone and its vicinity,we analyze the distribution of the modern tectonic stress-field of the Fault Zone and discuss the Characteristics of the focal rupture of the earthquakes alongside the Fault Zone.We find that the orientation of the main stress of focal mechanism is predominant.Focal rupture plane exposes the general state of the modern tectonic stress field of the Fault Zone and shows the main features of fo... |
