Abstract
In this talk I will highlight my group's recent contributions to the development of robust, predictive models of earthquake source processes, specifically through computational methods for simulating Sequences of Earthquakes and Aseismic Slip (SEAS). In SEAS models, the goal is to capture the interplay of interseismic periods and the associated aseismic fault slip that ultimately lead to earthquake nucleation and earthquakes themselves, in an effort to understand which physical factors control the full range of observables such as aseismic deformation, nucleation locations of earthquakes, ground shaking during dynamic rupture, recurrence times and magnitudes of major earthquakes. I will detail how we have addressed the challenges that arise from the varying temporal and spatial scales that characterize SEAS simulations, and how we incorporate material heterogeneities, bulk inelastic responses, fault non-planarity, and their evolution with time and slip. Both traditional numerical methods and machine learning approaches will be discussed in the context of forward and inverse modeling.
All are welcome.
