No CTC Event Summary because event is outside Shake. Alert Testing Region

No CTC Event Summary because event is outside the Shake. Alert Testing Region. This Shake. Map location has been relocated and the ANSS epicenter is further offshore.

The ”target region" for Shake. Alerts is considered all of California. This is the region for which we want to issue Shake. Alerts. We want to evaluate the Shake. Alert system performance for all events that might generate hazard-level shaking in the target area evaluate Shake. Alert performance for any events that might cause significant shaking in the target area. We define the Shake. Alert "testing region” (black polygon in figure below) as the catalog region we use to select events from the ANSS catalog. The “testing region” is about 100 km in each direction larger than the target region to include events that affect the target region with epicenters outside the “target region” This is the reason why the testing area is larger than California.
