CTC Results
The CISN Testing Center (CTC) consists of scientific analysis software, CISN EEW algorithm performance reports, and earthquake observational data. This entry is a collection point for current and past results from the CTC testing center.
CTC ShakeAlert Testing
As of September 2011, CISN Testing Center (CTC) processing now evaluates performance of the prototype CISN ShakeAlert EEW system. CTC evaluations are now based on earthquake parameter forecasts as logged by the CISN ShakeAlert system at U.C. Berkeley.
This testing include inputs from three algorithms (UCB Elarms, ETH Virtual Seismologist, and Caltech Onsite) as well as processing outputs from the ShakeAlert Decision Module.

CTC Interactive Performance Summaries
Prior to September 2011, CTC testing center produced interactive test results for individual EEW algorithms. These performance summaries are cumulative, with later summaries containing more events.
Interactive performance summaries are produced with a specific version of the CTC software in order to manage changes and improvements to the CTC processing software. Interactive results are reproducible by scientists as both the input EEW performance reports, and processing source code, are available from the CTC testing center.
