Event Description

The EarthQuake SIMulation (EQSIM) Framework for Fault-to-Structure
High-Performance Earthquake Simulations

The continued rapid advancements in high performance computing, coupled with increased understanding of earthquake processes, provides the foundation for a powerful new tool set for enhanced understanding of earthquake hazard and risk. As computational power increases, reliance on traditional simplifying idealizations and sparse empirical data can decrease, and attention can focus on understanding the fundamental physics of earthquake processes. Regional-scale ground motion simulations are becoming computationally feasible, and simulation models that connect the domains of seismology and geotechnical and structural engineering are within grasp. The EQSIM multidisciplinary application development project focuses on creating an unprecedented computational toolset for earthquake hazard and risk assessment. EQSIM is developing a framework for fault-to-structure simulations on the next generation of exaflop computers coming on-line at DOE National Laboratories in ~2022. This presentation will provide an overview of recent developments on the EQSIM framework including advanced algorithm development, workflow for regional simulations at billions of grid zones, and preparation for implementation on DOE’s exascale computer platforms.

How to Join

Instructions on how to access the virtual event will be sent to the email you use to register prior to every session. A recording of each session will be made available following the event.

David McCallen is the Director of the Center for Civil Engineering Earthquake Research at the University of Nevada, Reno (UNR) and a Senior Scientist in the Energy Geosciences Division at Lawrence Berkeley National Laboratory. In his capacity as Center Director, he is responsible for oversight and management of the state-of-the-art experimental earthquake simulation shake table laboratory at the University of Nevada. Dr. McCallen maintains an active research program and is currently the Principal Investigator for the U.S. Department of Energy funded EQSIM advanced earthquake simulation project, jointly executed by Lawrence Berkeley Lab, Lawrence Livermore Lab and the University of Nevada. Dr. McCallen’s research interests span from high-performance simulation of earthquake processes to advanced sensor and communication systems for structural health monitoring.

About the Organizers

The Committee on Geological and Geotechnical Engineering (COGGE) is the focal point within the Board on Earth Sciences and Resources for scientific, technical, and public-policy issues pertaining to the engineering applications of Earth Sciences. The committee’s scope encompasses Earth processes and materials, including the mechanics of rock and soil, and focuses on safe and responsible human development, risk assessment, and mitigation of natural and anthropogenic hazards. In addition, the committee provides a forum for discussion among academic and professional groups, government agencies, and private industry to enhance national and international cooperation and exchange of information.
