Cracking the secrets to earthquake safety, one shake simulation at a time BerkeleyLab
Two major research efforts seek to fill in the gaps and provide resources for researchers and engineers to study earthquakes across scales, from the initiation of seismic waves at the fault rupture site deep underground, to the interactions between shakingThe first endeavor is an experimental facility for real-world studies on how the soil around a structure influences its performance during an earthquake. The ground beneath us may seem solid, but vibrations can quickly make it unstable.
Studies conducted with the Soil Box System will provide data for the other effort, EQSIM: an ongoing collaboration between scientists at Berkeley Lab, Lawrence Livermore National Laboratory, and the University to develop realistic, highly detailed earthquake simulations using DOE's supercomputers. Once operational, the facility will become a resource for DOE researchers focused on seismic safety as well as scientists across academia and industry.
They will also soon start working on an even more capable platform—the newly launched Frontier supercomputer, also at Oak Ridge. Frontier is the first computer system to break the exascale barrier, meaning that it is capable of calculating at least a billion billion operations per second, and is currently ranked as the world's most powerful supercomputer.
