Are you all aware of the Flinn-Engdahl number?

It's a number used by NEIC to designate a geographic region. There are 729 of them, each corresponding to a place name and it's part of the information for each quake when you do a NEIC search and ask for compressed format.

I'm thinking of writing a program to check for this number so I can do a rectangle search for an area like California and then narrow it down to only California quakes. A rectangle search catches most of Nevada too.

Anyone else have a need for this?
