Hi all;

Here's something that may interest you. The FFA theory has gotten a lot of
interest lately and I got to wondering what the possible locations might be.

So I set up an array of one degree squares of lat/lon values and sorted all
let mag 6+ quakes into them. Then I counted the ones containing any quakes.
There were 1947 of them out of 64,800 possible locations.

Finally I checked each square containing quakes against all the other squares
containing quakes to see which ones were 103 drgrees away and added the place
names, resulting in the 50 locations listed below.

Actually there are only 25 pairs since the program looked at both ends of the
lines.
