Estimation of Recurrence Interval of Large Earthquakes on the Central Longmen Shan Fault Zone Based on Seismic Moment Accumulation/Release Model

Table 1

Parameters of fault model and accumulation moment rate in the seismogenic subsegments.

Seismogenic zone				Dextral rate; (GPS, Geol); (mm/yr)	Reverse rate; (GPS, Geol); (mm/yr)	Secular Rate; (GPS, Geol); (mm/yr)	Moment rate; (10^16 N m/yr)
Segment	Length (km)	Dip (°)	Depth (km)
Sa	68	43	12.74	1.7, 1.0	1.4, 0.3–0.6	2.2, 1.2	8.38
Sb	62	44	14.77	/, 1.3	/, 0.54	/, 1.41	4.75
Sc	41	49	9.85	1.7, 0.96	1.4, 1.1	2.2, 1.2	3.53
Sd	51	50	15.00	0.8, /	0.3, /	0.85, /	2.40
Se	60	56	13.32	0.8, /	0.3, /	0.85, /	2.31
Sf	47	90	14.03	0.8, /	0.3, /	0.85, /	1.58
Sg	63	28	14.77	/, 0.89	/, 0.23	/, 0.92	1.19

Dip angles and GPS rates are from [6, 39], as shown in Figure 3; geological rates are from [9–11, 46]; depth values are from Figure 4. Moment rate is calculated using formula (4).
