```Happy New Year Everyone,=20

Jerry,   This might help:   If you have a globe, I have a 12" dia. =
globe, you could compute the two different (P wave shadow zone at =
103-143 degrees) and the (S zone at 103-180 degrees,) into inches of the =
surface of your globe.    For a 12" globe, one degree=3D .104 inches.   =
103 degrees=3D 10.712 inches. =20
Using the appropriate length of string, place one end on your home town =
and using the other end of the string you could trace or otherwise mark =
its length all around the globe.  This line would represent the =
beginning of the 103 degree shadow zone.
However, I think I saw a wed site which may do this, using your =
Lat/Long, and those of the earthquake.

OK, lets start out the new year with a simple question for the group =
showing MY ignorance and lack of training!

I fully understand the theory and principle behind the Shadow Zones, =
but determining what MY shadow zones would be is confusing to me.  Has =
anyone built a windows software program to calculate what the shadow =
zones would be given my Lat / Long coordinates?

I understand the 104-140 degree zone that used, but I cannot correlate =
that into a spot or spots on the globe or map.  Can someone please point =
me in the right direction to solving this, please.

(If needed, my coordinates are 36.09N  094.13W.)

Happy New Year =
