Mike;

I do not disagree with anything you've said (Surprise!)

It is quite clear that eartones do not correspond to anything we understand as sound or even electromagnetic phenomena.

But if a reliable correspondence with earthquakes can be demonstrated, what then?

And that's what Petra is working toward. She chooses to do so privately for reasons of her own. No problem. It happens in science all the time. What researcher is going to share his preliminary results with unscrupulous peers who might publish before he could?
