Hi all;

progress report.

I decided to base the selected areas on the NEIC catalog, since that's the easiest source for current global quakes. Some of the chosen 6 squares shifted a bit for that reason and from the way integer math works on negative numbers.

Then I ran the program against the first 6 months of 2006, with the following results:

 LAT       LON      HITS   TRIES  HIT %  PROB. 
 36.00,   70.00,      2,      6,  .333,  .296  
 36.00,   71.00,      3,      6,  .500,  .346
 -8.00,  128.00,      3,      6,  .500,  .247
-16.00, -174.00,      2,      6,  .333,  .237 
-18.00, -179.00,      4,      6,  .667,  .422 
-21.00, -179.00,      4,      6,  .667,  .291
