Abstract: The Qinghai-Xizang Plateau, characterized by active tectonic movements and frequent seismic activity, serves as a natural laboratory for seismic research. Physics-based spontaneous rupture simulations are crucial in uncovering the dynamics and mechanisms of earthquake rupture. In this study, we review the advancements in spontaneous rupture simulation, focusing on fault modeling and numerical methods. We summarize the influence of factors such as fault geometry, initial stress, frictional criteria, and medium properties on rupture propagation, slip distribution, and final earthquake magnitude. Furthermore, we discuss the challenges faced in dynamic rupture simulations, particularly in constraining stress distribution on fault planes, medium properties, and frictional behavior. Additionally, we review the application of dynamic rupture simulations in reconstructing major earthquake scenarios, predicting seismic hazards, and assessing disaster risks. Looking forward, there is a need to develop dynamic rupture models with extended time scales and spatial coverage, incorporating earthquake cycles and interactions, and combine the kinematic inversion results, such as fault interseismic locking model within the Qinghai-Xizang Plateau. Such models would provide a more reliable scientific basis for construction earthquake rupture scenarios and disaster risk assessment.
