After a little thought it occurred to me that simple percentage would suffice.

There are 323959 quakes in my seismicity file. The program counts how many are inside ring 1, how many inside ring 2, subtracts and divides the difference by the total number to get the percent inside that ring.

And so on for the rest. When it gets to the end it hasn't found all the quakes.

I need someone to check it by hand.

Wanna volunteer? Shouldn't take over a year or so....
