SCEC SEAS Group Workshop on Exploring Complexity and Resolution in Earthquake Sequences

Conveners: Brittany Erickson and Junle Jiang
Dates:   November 29, 2018
Location: Kellogg West Conference Center, Pomona, CA
SCEC Award and Report: 18102

SUMMARY: The goal of this workshop is to share recent advances in modeling sequences of earthquakes and aseismic slip (SEAS) and continue with the community code verification exercises for SEAS models. The science talks include topics on earthquake simulations across different scales and connecting models with lab or field observations. The second SEAS benchmark BP2 explores the complexity in the simulated earthquake sequence and its dependency on numerical resolutions, motivating our strategy to interpret and resolve seismicity characteristics in larger-scale models. Discussion will be held about increasing the reach and impact of SEAS modeling through upcoming verification benchmarks and future validation efforts.
