Hi Glen. Sorry I can’t give you any particulars, as the data I use is proprietary. I first learned of it about 7 years ago. It works fairly well for location and time, but the magnitude leaves a lot to be desired. I never really, truly know what the magnitude of the quake will be.

I no longer receive the data so I have to work up my own. Have to admit the finished product is not as accurate as what I was receiving, but it does work once in awhile. Take Care…Don in creepy town
