Hi 2 Cents:

Let us have another round here: LOL

+ Could you download and install the sweep frequency tone generator and find/set the settings which most closely matched what you heard (assuming you can remember it that well ...since it was awhile ago....)?

I cannot download the tone generator as I don't have the sound unit hooked up to my computer. I would rarely use it and I've got to much stuff hooked up already.

"The tones travel at 37/38 miles per second. IE: if a 3 second tone arrives the epicenter will be between 111 and 114 miles away."

+ How many data points were used to come up with this approximation?

I can't say for sure, but more than 50.

+ How do you discriminate between a 3 second tone that is say 1000 miles away and 100 miles away ? Do you use "loudness" to discriminate?

A 3 second tone cannot be 1000 miles away. It can only be between 37/38 miles per second away. The volume of the sound is the magnitude indentication.

+ BTW, do you know of a (geology) map that shows where quartz crystals are found underground ?

No.

For clarity after numerous posts, let me list the method.

1. The length of the sound equals the distance to the epicenter. 37/38 miles per second.

2. The volume of the sound indicates the magnitude.

3. The type of sound (high pitch/granite, deeper/more soil compostion, fuzzy/volcanic, muffled/under water) determines where the epicenter will be.

4. The window, no more than ten days. If it does not arrive in ten days, then most likely it will not arrive at all.

From what I have seen with more people who hear ear tones, an area that frequently has earthquakes is much easier to forecast simply because you hear the sound many times. But the once in awhile event is very difficult.
