CTC 19 June 2011
These CISN EEW performance summaries were produced interactively using recent CISN EEW performance reports from ETH Virtual Seismologist and Caltech OnSite algorithms.
These summaries evaluate performance of the CISN EEW algorithms for approximately 20 ANSS earthquakes, primarily recent (June 2011) southern California events Magnitude 3.0 and larger. These summaries evaluate CISN algorithms. CISN ShakeAlert system performance information is not yet included.
ANSS earthquake used in evaluation are used under the following conditions: (1) The ANSS catalog defines earthquake parameters for a M3.0+ earthquake, (2) We have ShakeMap data for the event, and (3) one (or both) CISN EEW algorithms triggered and produced event forecasts (e.g. final magnitude forecast) or site forecasts (e.g. forecast peak ground velocity at site) for each event.

CTC Evaluation Run ID: 8552001
CTC Software Version: 11_06_19
Description: CISN EEW performance summaries using VS and OnSite performance reports. Catalog of events includes June 2011 ShakeMap events and several additional significant 2010 events for which we have EEW performance reports. The CTC zip file (below) contains all performance reports shown, and also includes the input observational data from ANSS catalog, and ShakeMap station observations, and the CISN EEW performance reports. These input data can be combined with a tagged version of the CTC evaluation software to reproduce these evaluation summaries.
