Hi Petra:

Lots of agreement....especially since only one or the other "ear" is seemingly involved at a time.

It may be that one phenomena in different versions is being experienced....

The question arises...how do you know which quake to attribute the "sounds" to (given the whole world and all where quakes are alwyas happening it seems)? This is where eartones coincident with ULF/ELF waveforms spikes in time might be useful in matching things up...to pull it into a quantitative (analysis) realm.

"The nods" huh? what's that? Seems like I might get a case of those around 'after lunch' sometimes (as in fighting off involuntary nap time...)

Can you hear quakes with mags greater than 5 ? (Not sure I followed you....).

I know some ULF waves can cause pain and organ damage in humans...so other symptons are not out of the question....

Sounds like Bob S. made some efforts in the direction of scientific study. I've a feeling that more advances in this area are soon possible ...time will tell.

Hope you had a good sailing trip. R u gonna post photos on ur site?
