Abstract

Abstract : The out‐of‐sequence thrust and the frontal thrust can be identified as a discontinuity in the displacement of the particles in the model.To illuminate clearly the stress change, the slip tendency (ST) (defined as the shear stress divided by normal stress) is calculated in the model. The slip tendency around the OOST is higher before a large slip event than those after the event, suggesting that the OOST was activated during a period of high slip tendency and that the slip tendency drops after slip upon the OOST.
