Subject: Shadow Zones


If given my exact location on the earth (lat/Long), is there a software program to show WHERE my "shadow zone" is located?   What area(s) would be excluded?
 
I understand Lat. / Long., but the degrees described with a shadow zone is a little confusing to me.
 
Hi Jerry,
 
     Can you get yourself a globe? Then take a strip of cardboard, measure the correct anglar length at the equator, put one end on your home location and use the other to scribe the circular zones with a crayon or similar. You are probably only interested in locations where the circles cross active quake zones.
 
Regards,
