SCEC4 Science Plan ""

Six Fundamental Problems in Earthquake Science!

1.  Stress transfer from plate motion to crustal faults: long-term fault slip rates

2.  Stress-mediated fault interactions and earthquake clustering: evaluation of mechanisms

3.  Evolution of fault resistance during seismic slip: scale-appropriate laws for rupture modeling

4.  Structure and evolution of fault zones and systems: relation to earthquake physics

5.  Causes and effects of transient deformations: slow slip events and tectonic tremor

6.  Seismic wave generation and scattering: prediction of strong ground motions

SCEC Initiatives!

•  Extreme-Scale Computing

–  To be supported by NSF and DOE

•  California Crustal Structure –  To be supported by California utilities

•  Earthquake Forecasting

–  To be supported by W. M. Keck Foundation


•  Goal: Collaborate with NSF and DOE leadership-class facilities to push the limits of extreme-scale computing by developing software for earthquake system science

–  Develop codes that can achieve robustness, scalability, and computational efficiency on next-generation supercomputers

–  Engage software and hardware developers in earthquake system science as a means for vertical integration of HPC cyberinfrastructure

•  Software development plan focused on three computational pathways: –  large suites (> 106) of extended-source kinematic simulations to populate

physics-based hazard models (CyberShake platform)

–  moderate-sized suites (~ 104) of dynamic earthquake simulations to study the effects of material heterogeneities and nonlinearities on wave excitation and propagation (High-F platform)

–  large suites (> 106) of compact-source kinematic simulations for full-3D tomographic inversions (F3DT platform)

SCEC Initiative in Extreme-Scale Computing!


•  Goal: to improve PSHA by reducing the epistemic uncertainties in the modeling of 3D path effects

–  Achieving this goal will require the gathering of new seismic data

•  Initial study phase will be focused in central California

–  Centered on the Diablo Canyon NPP

–  Initiated in January, 2015 •  Later phases could

potentially extend structural studies statewide

–  Long-term (10-yr) sponsorship by California utilities
