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 |
VP and VS 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.
