Petra,

geoForecasters has stated some strong claims. If they are overstated, as I strongly suspect they are, and people buy into them, they may set back earthquake prediction efforts another ten years, just as diffusion-dilatancy did in the 1970's.

They publicly state they can predict M2 events in California way ahead of time, but have so far offered no proof. They also said they have been able to predict all events greater than 6.5 for the last 18 months.

Berkland has been around a decade, and his claims remain to be documented, in fact most scientists consider them debunked.

Whitehead has a track record of presenting wild ideas as more founded than they are (check his AGU abstracts), and Kozuch has never written a paper to my knowledge about the physics of earthquakes.
