SCEC Workshop on Rupture Dynamics Code Validation and Comparing Simulations of Earthquake Sequences and Aseismic Slip

Conveners: Ruth Harris, Brittany Erickson, Junle Jiang
Dates: April 23-24, 2018
Location: Kellogg West Conference Center, Pomona, California

SUMMARY: The upcoming SCEC Workshop on "Rupture Dynamics Code Validation and Comparing Simulations of Earthquake Sequences and Aseismic Slip" will be held in Pomona, California on April 23-24, 2018. This workshop will start with talks by members of the SCEC dynamic rupture code validation group about their code validation strategies and other implementations of our dynamic rupture benchmark exercises. We will next transition to the new Simulations of Earthquake Sequences and Aseismic Slip (SEAS) group's portion of the workshop where we will discuss the unique challenges faced by SEAS models, introduce various codes used for SEAS modeling, and present our results from the first SEAS benchmark exercise.
