Estimation of Recurrence Interval of Large Earthquakes on the Central Longmen Shan Fault Zone Based on Seismic Moment Accumulation/Release Model
Figure 4
Fault model and focal depth of the seismogenic zone along the central Longmen Shan fault zone. (a) Fault geometry and segments viewed from the southwest, at 45° elevation angle (modified from [6]). Borders of fault segmentation are shown in Figure 1. (b)–(g) are statistic results of focal depth for segments Sa–Sf, respectively, according to the relocated aftershocks [28]. Statistical samples of each segment are aftershocks enclosed by segment borders, as shown in Figure 1. Black solid lines are regression curves of Gaussian distribution, which pass the Shapiro-Wilk Normality test. The value of preferred mean is estimated from the regression result.
