[S-TT41] Creating future of solid Earth science with high performance computing (HPC)

Sun. May 22, 2022 9:00 AM - 10:30 AM 301A (International Conference Hall, Makuhari Messe)

convener:Takane Hori(R&D Center for Earthquake and Tsunami, Japan Agency for Marine-Earth Science and Technology), convener:Yuji Yagi(Graduate School of Life and Environmental Sciences, University of Tsukuba, Tsukuba), Katsuhiko Shiomi(National Research Institute for Earth Science and Disaster Resilience), Chairperson:Takane Hori(Japan Agency for Marine-Earth Science and Technology)

Due to the development in computer science and computational science, large-scale or many times forward simulations and/or inversion analyses have become available recently. In solid Earth science, large-scale seismic wave propagation and crustal deformation with high fidelity models based on high resolution observation data have been demonstrated; uncertainty in crustal deformation caused by material properties and structures can be investigated based on many-time calculations for different material properties and structures; fault slip inversion analyses for non-Gaussian error distribution, etc. Thus, we will invite researchers who are applying HPC technology in forward simulations and inversion analyses and discuss how to improve more the collaboration between computer & computational sciences and solid Earth science. We are welcome submission by the researchers who are interested in this scope, especially students and young researchers.
