SCEC CSEP/USGS/GEM Workshop
Conveners: Max Werner (Bristol), Danijel Schorlemmer (GFZ Potsdam), Tom Jordan (SCEC/USC), Andy Michael (USGS), Morgan Page (USGS)
Dates:September 6, 2014 (10:00 – 18:00)
Location: Hilton Palm Springs Resort, California, USA
SCEC Workshop Report: 14148
OVERVIEW: The Collaboratory for the Study of Earthquake Predictability (CSEP), operated by the Southern California Earthquake Center (SCEC), provides a research cyber-infrastructure for independent and prospective testing of earthquake forecasts. As such, CSEP is well situated to evaluate operational forecasting models of earthquake potential and ground motions by the USGS, GEM and other international governmental and non-governmental organizations. The ongoing development and implementation of operational models, however, entail new requirements for CSEP’s infrastructure, methodology and experiment design.
The purposes of this workshop are: (i) to assess the evolving needs of agencies for CSEP-based testing of OEF and seismic hazard models, (ii) to disseminate and review recent CSEP and GEM Testing & Evaluation (T&E) results, (iii) to assess the adequacy of CSEP’s current methodology and infrastructure in light of evolving needs, and (iv) to gather community input on the next steps for testing OEF and seismic hazard models.
The workshop will bring together CSEP personnel, agency representatives, and scientists interested in the scientific and operational aspects of earthquake and ground motion forecasting and testing. This one-day workshop will include sessions on the following topics:
- Status and requirements for OEF and seismic hazard models
- Current CSEP capabilities and review of earthquake forecasts under testing
- Status and requirements for the short-term UCERF3 and GEM Global Earthquake Activity Rate (GEAR) models
- Results from short-term and global CSEP experiments
- Results from the retrospective Canterbury, New Zealand, experiment
- Operationalization: real-time forecasting and data considerations
- Status and requirements for seismic hazard models (GMPE’s, IPE’s, NSHMP)
- Review of seismic hazard models under CSEP and GEM T&E testing
- Discussion, recommendations and next steps for future CSEP experiments
