Full Reproducibility
The Testing Center keeps
─ All input data (e.g., earthquake catalogs)
─ All results
─ All simulations (e.g., random numbers)
─ System configurations used for computations (metadata)

CSEP V2.0
─ Fully XML-based
─ No Matlab -> Python/C++ -> Fully Open-Source
─ Scalable -> Cluster computing
─ Interactive web presentation
─ New tests (ASS, fault-based, etc.)
California Natural Laboratory
5-year models
─ Cellular Seismology (Kafka & Ebel)
1-year models
─ STEP (Gerstenberger et al.)
─ EEPAS (Rhoades)
─ EEPAS+STEP
─ PPE (Rhoades)
─ ETAS (Rhoades)
─ ETES (Zhuang, Kagan, Jackson)
1-day models
─ STEP (Gerstenberger et al.)
─ ETES (Zhuang, Kagan, Jackson)
─ EEPAS+STEP
Evaluation
─ Area Skill Score (Zechar)
─ Improving RELM-Tests (Rhoades & Schorlemmer)
California Natural Laboratory
─ Update completeness with PMC-method
─ Compilation of Completess-database for California
(USGS-NEHRP funding available)
Fault-based Testing
SCEC Community Fault Model
─ Fault database as model input
─ Forecast includes focal mechanism information
─ Test against catalog providing focal mechanisms
Fault-based Testing
─ Fault database as model input
─ Forecast includes focal mechanism information
─ Test against catalog providing focal mechanisms
─ Forecast smoothed to a grid
Why smoothing?
─ Difficulties in determining the ruptured fault (see Parkfield)
─ Rupture along unknown faults (see Loma Prieta)
Prototype Models
─ CALM (Tormann)
─ AMR (Bowman)
New Lab: Basin & Range
First meeting held at USC in April 2007
Data problems
─ Varying completeness
─ No homogenous magnitude reporting for entire area
─ Working group letter to ANSS
─ Completeness studies proposed to USGS
New Lab: Western Pacific
1-day models
─ Smoothed Seismicity (Kagan & 
Jackson)
1-year models
─ Smoothed Seismicity (Kagan & 
Jackson)
─ Evaluation of the rules set by 
Kagan & Jackson
─ First step to global testing
─ Help understanding problems of 
large-scale testing
New Natural Laboratories in Europe
Italy
─ Probabilistic completeness 
(Schorlemmer)
Iceland
Euro-Med Region
─ Probabilistic completeness of EMSC 
(Woessner & Schorlemmer)
─ STEP for Euro-Med (Woessner)
We Need to Discuss
Possible natural laboratories in Europe
─ Italy
─ Euro-Med region
─ Iceland
Data (earthquake catalogs) availability & quality
─ Any additional data available
─ Testing rules depend on data
Model availability
─ Data requirements
─ Coverage
