Hi Roger. It might help if you explained the difference between a prediction to be made and one that has already been made. It would help to know the method being used to predict the quake before the prediction is made. This is done in order to see if the quake has a chance to occur. In this instance the method is being evaluated and not the prediction.

For a prediction that has already been made the method doesn’t need to be known as only the prediction is being evaluated. Did the quake occur where it was said and did it occur when it was said it was going to occur and how close to the predicted magnitude was it. Take Care…Don in creepy town
