Table S3. Parameters Used in the Calculation of Coulomb Stress Change

Number	Layer	Width (km)	VP (km·s−1)	VS (km·s−1)	G (Pa)	η (Pa·s)	ρ (g·cm−3)
1	Upper crust	20	5.97	3.44	4.0×1010	1.0×1021	2.70
2	Middle crust	18	6.25	3.61	4.0×1010	6.3×1018	2.80
3	Lower Crust	8	6.4	3.70	5.0×1010	6.3×1018	3.00
4	Upper Mantle	1000	8.2	4.734	6.5×1010	1.0×1020	3.32

V_P and V_S are the velocity of the P wave and S wave, respectively. G is the shear modulus; η is the
viscosity coefficient; and ρ is the density of each layer.
