SCEC workshop: Earthquake Source Inversion – Planning of a Validation Exercise
Sunday, Sept. 7, 2008; 8:00 – 12:00
Organized by Martin Mai, Morgan Page, and Danijel Schorlemmer
8:00 – 8:10 Martin Mai: Introduction: Scope of the workshop & review of an initial blind-test ( SIV_Intro2008_Mai.pdf)
8:10 – 8:25 Morgan Page: Strategies for uncertainty assessment in source inversions (PageSCEC2008.pdf)
8:25 – 8:40 Yuji Yagi: Importance of covariance components for finite-source inversions
8:40 – 8:55 Kazuki Koketsu: Current status of source inversion methods in Japan

9:10 – 9:25 Ruth Harris: Experience from the Dynamic Code Validation Project
9:25 – 9:40 Danijel Schorlemmer: An existing testing center: CSEP ( Schorlemmer2008.pdf )
9:40 – 10:00 Coffee break
10:00 – 12:00 OPEN DISCUSSION – PLANNING THE SOURCE-INVERSION VALIDATION EXERCISE
10:00 – 10:40 DISCUSSION I : Science issues / General questions
- source inversion: an under-determined problem
- how to best quantify waveform fits ?
- how to optimally weight different data sets used in the inversion ?
- effects of source-receiver constellation ?
- effects of different stabilizing/smoothing constraints?
10:40 – 11:20 DISCUSSION 2: General set-up of the exercise
- Greens functions: pre-computed or velocity-density models specified ?
- Greens functions: Simple media or realistic structures ?
- source geometry: how much information should be provided ?
- what "data" (synthetics) are desired? Statics, strong-motion, teleseismics?
- "clean" synthetics or noise-contaminated ?
- how to compare inversion results; what are relevant statistical measures ?
- a fully prospective inversion ?
11:20 – 12:00 DISCUSSION 3: Logistics, Resource, Management
- overall strategy and rough time-frame
- formats for submission of models/synthetics ?
- Authorization of data streams ?
- needed computational/infrastructure resources ?
- proposal for future funding for these efforts ?
