Hi Petra,

Thanks for the info. I am curious and will keep a log going forwards just out of curiosity. Your comments about animals is interesting. I could see why an animal would howl or act strange if it got a tone in it's ear. It seems whenever I get these things the intensity level does not vary much from occurance to occurance, but length of occurance does vary, never less than maybe 5 seconds and never any longer than 30 or so seconds. How does one judge potential magnitude? Just by length of tone, meaning the longer it is the further away it is the larger the eq? When your basing a prediction on an ear tone, why not just make a prediction for a geographical ring rather than a single point? Or, better yet, the points that your ring cross active faults?
