Draft 2009 Science Plan
I. Petascale Cyberfacility for Physics-Based Seismic Hazard Analysis
(PetaSHA). SCEC’s PetaSHA aims to develop and apply physics-based predictive
models to improve the practice of seismic hazard analysis. This project will utilize
numerical modeling techniques and high performance computing to implement a
computation-based approach to SHA. Three scientific initiative areas have been identified
for this project to help to guide the scientific research. The PetaSHA initiative areas are: (1)
development of techniques to support higher frequencies waveform simulations
including deterministic and stochastic approaches; (2) development of dynamic rupture
simulations that include additional complexity including nonplanar faults, a variety of
friction-based behaviors, and higher inner /outer scale ratios (e.g. (fault plane mesh
dimension) / (simulation volume dimension)); and (3) physics-based probabilistic seismic
hazard analysis including probabilistic seismic hazard curves using 3D waveform
modeling. All of these modeling efforts must be accompanied by verification and
validation efforts. Development of new techniques that support the verification and
validation of SCEC PetaSHA modeling efforts are encouraged.
The SCEC PetaSHA modeling efforts address several of the SCEC3 objectives.
Development of new verification and validation techniques (B4) are common to each of
the PetaSHA initiative areas. Research activities related to the improved understanding
and modeling of rupture complexity (A8, B1) support the PetaSHA initiatives. In addition,
research into the upper frequency bounds on deterministic ground motion predictions
(B2, B3) are SCEC3 science objectives that are important work areas in the PetaSHA
Project.
J. Advancement of Cyberinfrastructure Careers through Earthquake System
Science (ACCESS). ACCESS provides students with research experiences in
earthquake system science to advance their careers and creative participation in
cyberinfrastructure (CI) development. Three programmatic elements:
• ACCESS-U: One-term undergraduate internships to support CI-related senior
thesis research in the SCEC Collaboratory
• ACCESS-G: One-year graduate internships to support CI-related master thesis
research in the SCEC Collaboratory
• ACCESS Forum: a new CEO working group to promote CI careers in
earthquake system science
IX. SCEC Communication, Education, and Outreach
SCEC is a community of over 600 scientists, students, and staff from 56 institutions, in partnership
with many other science, engineering, education, and government organizations worldwide. To
facilitate applications of the knowledge and scientific products developed by this large community,
SCEC maintains a Communication, Education, and Outreach (CEO) program with four long-term
goals:
• Coordinate productive interactions among a diverse community of SCEC scientists and with
partners in science, engineering, risk management, government, business, and education.
• Increase earthquake knowledge and science literacy at all educational levels, including
students and the general public.
• Improve earthquake hazard and risk assessments
• Promote earthquake preparedness, mitigation, and planning for response and recovery.
Short-term objectives are outlined below. Many of these objectives present opportunities for
members of the SCEC community to become involved in CEO activities, which are for the most
