Supercomputing Potential Impacts of a Major Quake by Building Location and Size

National lab researchers from Lawrence Livermore and Berkeley Lab are using supercomputers to quantify earthquake hazard and risk across the Bay Area. Their work is focused on the impact of high-frequency ground motion on thousands of representative different-sized buildings spread out across the California region. "While working closely with the NERSC operations team in a simulation last week, we used essentially the entire Cori machine - 8,192 nodes, and 524,288 cores - to execute an unprecedented 5-hertz run of the entire San Francisco Bay Area region for a magnitude 7 Hayward Fault earthquake."
