i ran the program using mag 7+ quakes as main quakes and looked for mag 6+ quakes within 30 days at 101 to 105 degree distances.

There were 548 main quakes but only 123 hits.

Then I sorted the file by degrees of latitude for the main quakes to see if the same locations showed up in the 103 quakes and actually found a few but so few that I can't rule out coincidence.

Too few to be useful in any case.
