Hi Shan. You would need 10 M>5.0 quakes to equal one M>6.0. You would need 100 M>5.0 to equal one M>7.0. They would have to occur one right after the other and at the same location.

The first quake was 326Km from your forecasted location. The second was 613Km. That is outside the range you gave. In as much as you are the only one using the method you use this isn’t to bad of a forecast. Take Care…Don in creepy town
