I don't want to rain on anybody's parade here...but the 5.7 aftershock was entirely predictable simply because it followed the larger quake by a few weeks and was in the zone. I would guess that we'll see something more very soon on the Coyote Creek or San Jacinto Faults, simply because the stress seems to have transferred there.

I see many "spikes" on EQF's pages all of the time. I don't claim to understand his methods, but it seems that most of these spikes do not produce anything of significance.

However, as always, I encourage people to keep trying. If somebody comes up with a good method that can predict size, place and reasonable time window for a quake on a recurring and comprehensible basis that beats simple chance, I say go for it. The planet will do what it wants...and right now we are often simply observers.

Ahem...I DID predict the April quake a few hours before it happened. But that was merely a hunch based upon a few 4 plus quakes that had popped up in a previously fairly quiet place. I would not be surprised at all if a four or larger quake occurred near the northern end of that aftershock zone, especially on or near the Coyote Creek Fault. In fact, I predict on of four or larger within the next month within a fifty mile radius. There...stuck my neck out on a hunch!
