Most Advanced Bay Area Earthquake Simulations Will Be Publicly Available

Researchers at Lawrence Berkeley National Laboratory (Berkeley Lab), Lawrence Livermore National Laboratory, and the Pacific Earthquake Engineering Research Center (PEER) plan to release to the public the most accurate, detailed, and up-to-date earthquake simulations for the San Francisco Bay Area. The collaboration's simulation software, EQSIM, developed using Oak Ridge National Laboratory's (ORNL) Summit supercomputer and Berkeley Lab's Perlmutter supercomputer, produces "ground motion simulations of unprecedented fidelity and unprecedented spatial coverage," according to Berkeley Lab's David McCallen. Said PEER's Khalid Mosalam, "The upcoming simulation-based dataset will be instrumental for facilitating deeper understanding of the hazard, performance, and overall resiliency of California, allowing officials to identify the infrastructure systems and structures that pose the largest risk in an effective and accurate manner, and properly allocate resources."
