Researchers at the Earthquake Research Institute (ERI) of Japan’s University of Tokyo are using the IBM AC922 Summit supercomputer at the Oak Ridge Leadership Computing Facility (OLCF) to simulate the Cascadia Subduction Zone, a tectonic plate boundary that runs from Vancouver, British Columbia in Canada to northern California.

The researchers transformed the Unstructured fiNite element ImpliCit sOlver with stRuctured grid coarseNing (UNICORN) code into an artificial intelligence–like algorithm, and ran it at 416 petaflops, resulting in a 75-fold speedup from a previous state-of-the-art solver. The researchers said the new solver can aid scientists in long-term earthquake forecasting.
