2008/10/29 CSEP meeting

Attendees: Yan K., Phil M., John Y., Masha L.

1. Kagan-Jackson Smooth Seismisity model for California:
   • Masha changed the code to read ZMAP format of input catalog:
     1. Converted Yan's ANSS catalog to ZMAP format
     2. Verified that model generates the same forecast when using Yan's ANSS and ZMAP format catalogs
   • Masha generated forecast using CSEP generated ANSS input catalog:
     1. Sent summary of observed percent differences as map to Yan for review
        • Yan pointed out to high percent difference for longitude=-120.33 and latitude=35.5
        • Masha converted ZMAP format of CSEP generated catalog to Yan's format for easier comparison, and discovered:

          1. Trac ticket https://intensity.usc.edu/trac/csep/ticket/113

          2. Trac ticket https://intensity.usc.edu/trac/csep/ticket/114

        • Ticket #113 affects only forecasts that use input ANSS catalogs with start date before January, 1966 (that have missing depth values):
          1. Jeremy's five-year models
          2. David Rhoades three-month models
        • Ticket #114 affects all input and observation catalogs generated by CSEP
     2. Yan suggested to meet with Dave and Danijel to discuss rules for input catalog event selection:
        • RELM collection area vs. Yan's 500 km window
        • Magnitude cut-off at 3.95 vs. presently used 4.0
   • Masha will continue the work on automating the model within CSEP:
     1. Will use ZMAP format of Yan's input catalog for the acceptance test
     2. Have to apply scale factors provided by Yan to get magnitude bins for generated forecasts:

        • Will use M>=3.95 table for short-term and long-term forecasts

        • Will ignore bins with 3.95<=M<4.95 for long-term forecast

     3. Long-term and short-term forecasts are matching with less than 0.5% differences compared to Yan's forecast
2. Upgrade of New Zealand testing center to CSEP V8.10:
   • Waiting for Matt to upgrade
   • Remaining tasks:
     1. Danijel will work on GMT script for forecasts maps
     2. Grid shifting - Danijel suggested to use global grid notation
     3. Web-viewer for the results, still to be resolved to use:
        • Stand-alone web page or
        • Introduce as new testing region within existing CSEP results page
3. Tasks for CSEP V9.1:
   • Masha will send an e-mail to Max asking if he will submit his model:
     1. One-day ETAS model for California
   • Anna Maria has not responded yet if she will work on resolving an issue for SWPacific testing region:
     1. New csep-devel server reproduces the problem observed on csep-cert
   • Kagan-Jackson Smooth Seismisity models for California:
     • Long-term (5-year)
     • Short-term (1-day)
   • Masha will ask Danijel if global testing is scheduled for the release

   • Toolkit documentation for CSEP

   • Source code documentation - to make it available through the web
4. csep-op:
   • John said that new hard disk is here, waiting for Maureen from HPCC to bring it on-line
   • There are still about 550Gb available which should last for roughly 4 weeks
