The Theoretical & Computational Seismology Research Group, Princeton University, along with researchers at Rice University and University of Toronto generated this 3-D simulation of the earth under Hangai Dome from seismic data. The scientists used 1.7 million seismic wave measurements from 227 earthquakes across East Asia in their computer simulations to compile 3-D images of the subsurface rock formations. From these maps, they will be able to answer questions about the tectonic evolution of surface landforms and identify subsurface structures that may pose earthquake hazards. The simulations and data processing were done using XSEDE (Extreme Science and Engineering Discovery Environment) supercomputers at the Texas Advanced Computing Center at the University of Texas at Austin and the DAVinCI supercomputer at Rice University.
