I ran your June 29, 2004 signal through my computer programs. And it identified the earthquakes listed in the first table listed here. My bet would be that you detected the approach of the 6.4 magnitude one in the Kuril Islands.

The second table lists past earthquakes which matched your signal based on probabilities (100: or 97: etc.). The fact that there are several high probability ones around 149E longitude (+149) suggests to me that that 6.4 magnitude Kuril Islands earthquake could be the one responsible for your June 29 Ear Tone.

It is my opinion that for detecting the approach of - destructive - earthquakes occurring around the world the technology which I have developed is presently as much as 25 years ahead of anything available anywhere else. And as you can see by those data it might also be useful for telling where harmless ones responsible for Ear Tones are occurring.

If you convert more of your signals to UTC time and send the list to me by e-mail or post it here then I will try running all of them through my computer programs.
