it usually means that there is perhaps a 75% chance that within 4 or 5 days there will be a powerful and possibly significant earthquake somewhere.

How exactly does one rigorously evaluate a statement with so many waffle words?

I did think that an expected one for the central Asia to Indian Ocean area would likely occur within 5 days starting on May 18.

My last warning was circulated on May 18. And people around the world saw it. On May 19 there was a moderately powerful earthquake in Turkey that reportedly claimed at least 3 lives.

Turkey doesn't seem to be in the predicted area. Two larger earthquakes struck the 18th (New Guinea, M6) and the 20th (Tonga, M6.2). M6s are not at all usual, and M5s strike daily.

The posted thoughts do not support the premise either that these predictions have ever been evaluated or that the connection between the prediction and the earthquakes has been assessed properly.
