Project Abstract
 The SCEC Workshop on Advancing Simulations of Sequences of Earthquakes and Aseismic Slip (SEAS) was held on Nov. 2nd, 2021, remotely on Zoom. A total of 60 people participated. This year our workshop attendees included scientists from the U.S.A., Sweden, France, Switzerland, China, Germany, England, Japan, Canada, Brazil, and New Zealand. Almost half of our workshop participants were either graduate students or postdocs. This workshop discussed results from our recent 2D and 3D benchmark problems produced by the SEAS group, which include important new features of full dynamics, dipping fault geometries and 3D effects, and outlined details of our upcoming benchmark problems. The workshop also included scientific talks given by SEAS modelers. Many thanks to Tran Huynh and Edric Pauk for all of their work that helped make this workshop successful.
Intellectual Merit The SCEC workshop was the primary meeting of our SCEC-SEAS group and other parties interested in computational earthquake cycle simulations.
Broader Impacts The SCEC workshop was the primary meeting of our SCEC-SEAS group and other parties interested in computational earthquake cycle simulations.
Exemplary Figure Figure 2. Rupture contours for BP4-QD (whole space problem) show excellent quantitative agreement at suggested resolution (0.5 km) across participating codes. The high computational demand limits participating models at the suggested resolution (BEM/SBEM models), however good agreement is achieved for more models (BEM/SBEM/FEM/FDM) at 1 km resolution (not shown).
