Simulation study for understating earthquake cycles and earthquake forecasting


In earthquake cycle simulation (ECS), we construct a model that can explain the occurrence of multiple slip events, including large earthquakes and simulate the slip evolution. ECS leads to understanding the earthquake cycles and earthquake forecasting. For ECS, both the studies of developing the ECS technique for more reliable stress estimation and investigating the earthquake cycle are essential. In this seminar, I introduce some of my studies; (1) large-scale ECS technique and (2) the effect of repeating SSEs on a large earthquake. Now I am developing an ECS taking the viscoelastic effect into account and applying a data assimilation method to the ECS model. It will lead to more realistic modeling of the postseismic deformation.
