I do not have time to go into this in detail right now. But think of the generation of these warning signals as being something like the decay of a radioactive atom. The time that the atom will break apart is dependent on what element and what isotope it is and on probabilities. Similarly, the time delay between a warning signal and the earthquake can vary depending on a number of factors. With the signals that I work with the earthquake will occur within a few days perhaps 40% of the time, within two weeks 60% of the time, and within two months 80% of the time. I am just pulling those numbers out of the air for illustration purposes. I have not actually done a statistical evaluation of the data.

I detected what I believe were clear signals pointing to the destructive June 22, 2002 earthquake in Iran almost exactly two months before it occurred. More were detected a month before the earthquake and an advisory for that general area was circulated at that time.
