AB: The SCEC Community Modeling Environment (SCEC/CME) collaboration is extending SCEC's program of seismic hazard research using high performance computing with the NSF-funded Petascale Cyberfacility for Physics-based Seismic Hazard Analysis (PetaSHA) Project. The SCEC PetaSHA project is a collaboration of geoscientists and computer scientists that integrate geophysical numerical modeling codes with leading-edge cyberinfrastructure to perform seismic hazard research at large-scales and high-resolution using national academic supercomputing facilities. The PetaSHA computational capabilities are organized around the development of robust, re-usable, well-validated simulation systems we call computational platforms. Researchers on the PetaSHA Project are currently developing the DynaShake Platform (dynamic rupture simulations), the TeraShake Platform (wave propagation simulations), the CyberShake Platform (physics-based probabilistic seismic hazard analysis), the BroadBand Platform (deterministic and stochastic modeling of high frequency synthetic waveforms), the Full 3D Tomography (F3DT) Platform (improvements in structural representations), as well as using and extending the OpenSHA Platform (Probabilistic Seismic Hazard Analysis). We will describe several current PetaSHA research projects including the application of the DynaShake Platform to dynamic rupture modeling of the ShakeOut source, the use of the TeraShake Platform, including the URS- Graves, SDSU-Olsen and CMU-Hercules Anelastic Wave Propagation codes, to model 1Hz ShakeOut simulations, the use of the CyberShake Platform to investigate physics-based PSHA hazard curves, and the use of the F3DT Platform to produce an improved structural model for a large region in southern California.
