The morning a few hours before the earth quake, she opened the front door and the dog wouldn't go near it. Your example is cool (thanks), but that isn't enough time to be helpful, if there was at least 15 to 30 minutes or so, of warning, then I think it could be useful.
I had an idea over ten years ago, that I hoped could save lives and make me money, but I'll never do anything with it, so here it is:
One animal acting strange (as in before an earth quake or whatever) is nothing, but a large number of animals in a specific area, could very possibly be a warning of impending danger. If there was a (well known) web site that you could report your animal acting "weird", or out of the ordinary to, you would have random reports from all over the place, but if you mapped results in real time and saw a lot of activity in a specific area, that could be an early warning. I don't see why it wouldn't work, assuming the "animals act weird before events" theory is correct.
Anyway, if this works and saves lives, remember you heard it here first.
