Hi 2 Cents,

Let me do a cut and paste to answer your questions:

What city are you in/nearby nowadays anyway ?

I live north of Petaluma about 12 miles.

Do you think eartone frequency (also) indicates the magnitude of the quake versus distance ?

The loudness of the sound heard determines the magnitude of the quake x distance ie: length of tone. Let me use the Nisqually quake for an example. The length of the sound was 15 seconds, but it was really loud, so I knew this quake was going to be extremely large. It also had a very unusual tone, one that I had never heard before. The original tone was heard and then at the end it sounded like the tone was spreading out in a circular way. Imagine a typical epicenter circle and the sound traveled outward.

As far as distance, it seems it would be desirable to match the time of the eartone to perhaps a ULF/ELF spike in an instrument somewhere in order to try and figure the time of the "eartone cause" event and where it might be "sourced"...(and from that get the distance to the "source location"....). Of course, if it's an x-ray flux event then you could get a time (but not a location per se).

Don and I figured this out some time ago. 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.

Couldn't two different quake precursor eartones both have the same duration but yet be located very far away from each other? Just a thought....

Yes. Each area has its own geology and from knowing the geologic structure, then you know where the sound eminates. Very solid rock such as granite produces a very high pitched sound, area's more dense in soil are muffled, volcanic area's sound like the basic sound with a fuzziness around the edge of the sound. Off shore can sound like one has their head under water.

Also, perhaps you could identify the frequency you are hearing (see link below on free tone generator...). So far we've got 3000, ~5000-6000, and 7000 cps (Hz) as what is being heard....
(and some mid-C's (?) but I don't know the frequency exactly....)

As I said earlier, I don't believe these are true sounds, but rather vibrations perceived as a sound. Each sensitive hears sounds/vibrations and only they know from experience where they come from. Its always a lesson inside of a lesson.

Often times people who do not hear ear tone vibrational sounds think the sensitive is suffering from tenitus. It took me two years to explain to Don over and over again that I did not have tenitus, but heard a single sound and it came and left in a short period of time.
