Thanks Shan, Now I have a much better understanding of how your method works!

Could you help me to understand how you identify where a quake is most likely to occur after you see an anamoly on your graph? I'll go back through your earlier posts and see if I can put it all together, but what I need to know is how you get from recognizing the anamoly to identifying where the strain on the earth is the greatest, and hence where it is likely an earthquake will occur.

Thank you again, Billion
