Summary

Physics-based models of Sequences of Earthquakes and Aseismic Slip (SEAS) connect geophysical observations to the processes governing the seismic cycle, from interseismic loading and aseismic slip to earthquake nucleation and dynamic rupture. As models incorporate additional physical processes and structural complexity, including fluid pressure evolution, depth-dependent stress, material heterogeneity, and complex fault-system geometry, the resulting range of temporal and spatial scales creates substantial numerical challenges and makes community verification essential. Our group is working to advance computational methods for simulating Sequences of Earthquakes and Aseismic Slip (SEAS) by conducting a suite of code verification exercises.

This workshop will bring together earthquake scientists and modelers for a science-driven discussion organized around current science directions within the SEAS community and corresponding benchmarking efforts. The workshop will cover topics related to fluid-induced slip, computational challenges associated with SEAS modeling, and the role of incorporating multifault interactions and fault geometries. Invited talks will place current and proposed benchmarks in the context of broader research themes. We will conclude the workshop by discussing the next steps for benchmarking SEAS models that adopt 3D geometries adapted from the SCEC Community Fault Model (CFM).

Workshop Goals

We aim to discuss with the SEAS community our most recent modeling efforts, such as the comparison of submitted results from our most recently released benchmark, BP8, and the introduction of our upcoming benchmark, BP9. We also want to initiate a community discussion on adapting complex 3D fault geometries, geared towards the development of a new long-term benchmark direction.

Participation

The workshop is open to researchers, model developers, students, and others interested in sequences of earthquakes and aseismic slip simulation, dynamic rupture simulation, earthquake-source physics, and code verification.
