  1. Review of ANSS and possibilities for the catalog of the future Paul Earle NEIC - Golden, Colorado

  2. Outline • ANSS review • ANSS defined • Motivation and Organization • Products • Defining a new catalog (Catalogue) • Content? • Access? • Processing?

  3. ANSS The Advanced National Seismic System will modernize and integrate earthquake monitoring and response in the US.

  4. Seventy-five million Americans in 39 States are exposed to significant earthquake risk

  5. National Inventory 1500+ analog stations ~300 broadband stations ~800 digital SM systems

  6. Scales of Seismic Monitoring • Global - worldwide monitoring and reporting • National - nationwide monitoring and reporting • Regional - regional monitoring and reporting • Urban - emergency response and engineering data • Portable - special aftershock studies

  7. Planning Considerations • Project TriNet as a model of the joining of strong motion and regional networks. • Regional elements serving regional needs. • National oversight group representing all interests. • National structure tying elements together in one system

  8. Required ANSS Infrastructure • National Backbone Network: +44 stations to complete USNSN • Regional: +1,000 stations to modernize regional networks • Urban: +3,000 new instruments in structures • Urban: + 3,000 new ground stations • Portable: 2 arrays of 25 stations

  18. Intensities Maps Waveform data Station metadata Specialized reports Catalog ANSS Information Products Recent earthquake maps

  19. Intensities Maps Waveform data Station metadata Specialized reports Catalog ANSS Information Products Tectonic summaries

  20. Intensities Maps Waveform data Station metadata Specialized reports Catalog ANSS Information Products

  21. Intensities Maps Waveform data Station metadata Specialized reports Catalog ANSS Information Products Station information Coordinates Instrument type Instrument response Near surface geology Site classification

  22. Intensities Maps Waveform data Station metadata Specialized reports Catalog ANSS Information Products Special reports will be generated for subsets of all data for the different processing stages

  23. Intensities Maps Waveform data Station metadata Specialized reports Catalog ANSS Information Products This brings us to the second part of the talk… What should the catalog/bulletin look like?

  24. Catalog of the Future • How do we remain relevant? • Content? • Access? • Processing?

  25. Who was our customer?

  26. Who are our customers?

  27. Content? Ideally the derived information (hypocenters, magnitudes, errors, etc.) should be reproducible using information in the database. This means in addition to storing the “raw” data, the actual processing algorithms and programs should be part of the catalog. Additionally, the user should be able to modify the processing details to produce a custom catalog.

  28. Future catalog structure? User input DBMS Programs Products

  29. Content • Picks times/amplitudes • Hypocenters • Magnitudes • Moment tensors • Extended comments • Maps and pictures Need complete channel information Need processing details technique Filtered? Corrected for acausal effects? Hilbert transformed?

  30. Content • Picks times/amplitudes • Hypocenters • Magnitudes • Moment tensors • Extended comments • Maps and pictures Need processing techniques, earth model etc..

  31. Content • Picks times/amplitudes • Hypocenters • Magnitudes • Moment tensors • Extended comments • Maps and pictures Damage reports, Casualties, Triggered effects

  32. Content • Picks times/amplitudes • Hypocenters • Magnitudes • Moment tensors • Extended comments • Maps and pictures Shakemaps, Intensity maps

  33. Access • Better search routines • Flexible search routines with user definable output format • Easy to use, web accessible • Visualization techniques • Maps • Easy to use, web accessible

  34. Easy targets • Expanded comments (expand significant events lists) • Better search routines (public access to DBMS tools) • Better visualization techniques (e.g., Anthony Lomax’s Seismicity viewer)

  35. Processing We need to move beyond batch processing and cutoff dates. Is it better to be consistent or correct? Why exclude data that arrives past the cut-off date? Why use more data when it does not significantly improve the location and magnitude?

  36. Parting thoughts • Should we extend the concept of a catalog to include processing techniques as well as raw data? • Should we drop batch processing? • What are the easiest targets to enhance our catalogs for growing consumer diversity?

  37. ANSS progress to date • Formation of a management structure that can implement ANSS • Development of technical implementation guidelines for all aspects of ANSS • Annual completion of station installations (~250 strong motion and broadband stations installed in 24 months) • Successful recording of the M6.8 Nisqually earthquake • Standardization across the United States on earthquake information products
