Apprectiate the comments from everybody.

I am going to move forward with it. I am talking to some of the people who work there about observation techniques that may give clues to coming earthquakes. I will post here again asking for some suggestions. I don't want to re-invent the wheel here though, so it is good to hear about things that have been tried before. What is interesting is the range of species there. I'll get back..

thanks again,
