  1. SCEC Digital Library Marcio Faerman Yuanfang Hu Visakan Kalimuthu Yi Li Reagan Moore

  2. Southern California Earthquake CenterOverview and Goals • Gather information about earthquakes in Southern California, • Integrate information into a comprehensive and predictive understanding of earthquake phenomena, • Communicate this understanding to end-users and the general public in order to increase earthquake awareness, reduce economic losses, and save lives • Community comprises 51 participating institutions http://www.scec.org • SCEC/CME – Community Modeling Environment http://www.scec.org/cme

  3. SCEC Digital Library – Key Issues • Access and Management of SCEC Information • Simulations • Observations • Provide services for the interactive manipulation of SCEC published data • Discovery and Presentation of SCEC collection material • Metadata annotated collections • Integration of SRB supported SCEC Digital Library with Earthquake Applications • Data Analysis and Visualization of massive datasets

  4. SCEC/CME Digital Library Portal • Aggregates multiple views of SCEC Digital Library Collections • Scenario-Oriented Interface • MySRB • Visualization Tools • Chat, Discussion, etc. • Based on • Portlets • Open Grid Computing Environments • GSI Authentication capability • Access Control • Can be expanded with new functionalities • User Customizable

  5. Select Receiver (Lat/Lon) Output Time History Seismograms Select Scenario Fault Model Source Model SCEC Community Library Scenario-Oriented Interface3D Ground Motion Project for LA Basin • Intuitive User Interface • Pull-Down Query Menus • Graphical Selection of Source Model • Clickable LA Basin Map (Olsen) • Seismogram/History extraction (Olsen) • Access SCEC Digital Library • Data stored in a data grid • Annotated by modelers • Standard naming convention • Automated extraction of selected data and metadata

  6. Scenario-Oriented InterfaceMetadata Extraction

  7. Scenario-Oriented InterfaceReal-Time Parameters

  8. Real Time Interaction

  9. TeraShake Earthquake Simulation • Simulation of large earthquake occurring on southern San Andreas fault • Kim B. Olsen (SDSU) • Scientific and Engineering interest • Southern California, • Northern Mexico, • Earthquake Community

  10. TeraShake Simulation Parameters and Output • 600Km x 300km x 100km • Spatial resolution dx = 200m • Mesh Dimensions • 3000 x 1500 x 500 = 2.25 Gpoints • Simulated time = 200s • Number of time steps = 20,000 • Will run at SDSC DataStar • 60 TeraByte Output will be registered with SCEC Digital Library
