Hi Bob. It’s doubtful that the data would be much good beyond the forecasted epicenter. That is why I use a maximum of 65Km. The data for the forecast is only good for the forecasted epicenter and as such it will not be the same at 80Kms from the forecasted epicenter.

This is the reason for using a tight radius. The quakes will either occur within a minimum specified range, or they won’t. Of course there is always a chance it can trigger a quake outside the limits and this would most likely be for a quake that was only hours away from occurring on its own accord. There is no way at present time to say with any degree of certainty when this would happen. Take Care…Don in creepy town
