I think he still lurks from time to time. His efforts are interesting. I like his approach. But unfortunately big quakes don't happen often enough so it will take time to gather more data.

More specific please. Mag and date range?

I think(?) Chris means in general that even getting just the magnitude and date right would be meaningful - "mag 7.5+ within 5 hours of date/time XXX". Do that enough times and I thing significance would be high. My skeptical mind though has trouble thinking of a way that there could be some precursory phenomenon that could be detected that could give size and time information without location. All forms of energy radiate from specific locations and directional information can be obtained with suitable instruments.

On the other hand, maybe Chris would like to see analyses of quake predictors without regard to location and see how they do. The software run through the catalogs should be very quick then.
