Hi Alan. I have been using your program for about a year now. I have found it very useful in seeing how one quake occurs in relation to another. I have found that it helps for a better understanding in the relationship between quakes.

When I was able to see how the quakes were occurring at Mammoth Lakes I knew almost for certain that a good majority of those quakes were volcanic in nature.

I see you have another program that I will download tonight.

Tell your Father I enjoy his music. Take Care…Don in creepy town.
