negative dislocation
1.Negative Dislocation Model for Vertical Crustal Movement before and after M_S8.1 Earthquake in the West of Kunlun Mountain Pass
2.It is discovered that the Coulomb failure stresses are all positive on the fracture plane of 5 aftershocks under the condition of 16 combinations of the estimated length, width and dislocation quantity. However, the change varies 10 -3 ～10 -1 MPa. And positive and negative varies for other 2 aftershocks.
