Standardized Rupture Description Development
(Scenario Ruptures)

• Coarse slip distribution and hypocenter initially
  specified

• Extend to fine-scale sampling using K-2 filter
  (e.g. Somerville et al., 1999)

• Rupture time derived from simple scaling formula

Generating a Concrete Workflow

• Information
• location of files and component Instances
• State of the Grid resources
• Select specific
• Resources
• Files
• Add jobs required to form a concrete workflow
  that can be executed in the Grid environment
• Data movement
• Data registration
• Each component in the abstract workflow is turned
  into an executable job

Welcome to the SCEC/CME 2005 All Hands Meeting

• Ask Questions and Contribute to Discussions.
• Find Problems to work On and People to Work with
  for Year 5.
• Communicate, Innovate, and create Transformative
  Science

35
SCECs Mission

• SCECs Mission leads to Geoscientists working
  together with Computer Scientists
• Gather information about earthquakes
• Integrate into a physics-based understanding
• Communicate understanding to community

36
Seismic Hazard Analysis

• Definition Specification of the maximum
  intensity of shaking expected at a site during a
  fixed time interval
• Example National seismic hazard maps

• Intensity measure peak ground acceleration (PGA)
• Interval 50 years
• Probability of exceedance 2

SCEC/CME Challenges

• Many geophysical models, computational programs,
  and data sets and data types.
• Large scale simulations, high performance
  computing and large-scale data management are
  required in a physics-based approach to
  earthquake modeling at high spatial-temporal
  resolution requires.
• Communication tools, distributed model
  development, and computer resource sharing are
  required by the distributed SCEC collaboration.
