SCEC Workshop on Advancing Simulations of Sequences of Earthquakes and Aseismic Slip

Conveners: Brittany EricksonValere Lambert, and Junle Jiang
Dates: November 18, 2022
Location: Online via Zoom
SCEC Award and Report: 22123

SUMMARY: 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. In SEAS models, the goal is to capture the interplay of aseismic fault slip—that ultimately lead to earthquake nucleation—and dynamic earthquake ruptures themselves, in an effort to understand which physical factors control the full range of observables such as aseismic deformation, earthquake initiation locations, ground shaking during dynamic rupture, recurrence times and magnitudes of earthquakes.

The goal of this workshop is to discuss developing community activities revolving around and of interest to SEAS modeling efforts and to compare results from our most recent benchmark problems BP6 and BP7, which focus on fluid and 3D effects, respectively, as well as different treatments of fault friction. We will also discuss research targets and plans for SEAS in the near and longer term for the group.
