摘要

Deformation resulting from slip on a fault plane creates stress changes in the surroundings. The stress change formulated in the Coulomb stress equation has been used to explain this type of seismic interaction. However, the sensitivity of the input parameters needs to be assessed, including the earthquake source fault geometry and the regional stress. Range analysis based on the Taguchi orthogonal array has been widely used in experimental designs to analyze the result sensitivity based on the parameters. In this study, we incorporate the Taguchi orthogonal method to analyze the sensitivity of static Coulomb stress transfer in relation to the source fault geometry and the regional stress magnitude. The 2016 Pidie Jaya, Aceh earthquake (Mw = 6.5) in Indonesia, was used as a case study. Our sensitivity result shows that the dip and strike of the source fault are the first and second parameters that have the most effect on the distribution of static Coulomb stress transfer. We, thus, used additional constraint to model these parameters, i.e., the Pidie Jaya earthquake aftershocks which were obtained from a dense local seismic network. Using the updated input model, we conducted Pidie Jaya earthquake static Coulomb stress modeling. The stress results show a better agreement between positive stress change and the aftershock distribution.
