Brian;

I can tell you without looking that there is a pattern to the distances. it starts out high, drops rapidly to a fairly low level which is consistent out to 180 degrees. There is a gentle rise to 90 and an equally gentle decline thereafter.

The reason for the slight hump at 90 is because 90 degrees is the largest circle from anywhere on a sphere, thus the most likely to hit other seismic areas. There is no peak at 103 degrees.
