All: Don and I echanged some email and we realized that it would be a bit of a pain for me to display the data and I'm not getting my regular work done...aslo...the list Don sent was widely scattered quakes. many just set to 30 km depth, so would not be worth displaying in 3D...plus, Don wanted to know what the dips of the faults were, and it is better to just look at the focal mechanism when you have large scattered quakes...So, I'm not going to do this...Chris
