CTC Results
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.
Links to current ShakeAlert performance summaries are posted on the CTC Results entry.
CTC Interactive Performance Summaries
Prior to CTC performance summaries are (currently) produced interactively using the CTC software are posted by processing date. These performance summaries are cummulative, 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.
