So, let's get this right. Are you suggesting that the USGS instruments buried a few feet underground are immune to diurnal temperature cycles..

Ok, Tom, to recap..

I wrote..

does that change in tilt that happens because of the heating and cooling of the atmosphere

And wrote again..

the meter is in a bore hole 3 - 4 meters underground, in rock that is effected by the daily heating and cooling cycles of the atmosphere

And again..

So we have an instrument, a meter, in an environment that is both deep enough in the ground to get a clean reading of its motion without being overwhelmed by interference, noise, from the surface, and yet is not deep enough to avoid being influenced by the heating and cooling of the surrounding rock due to atmospheric changes.

And still after all that you came back with..

You are suggesting that the USGS instruments buried a few feet underground are immune to diurnal temperature cycles

If I say something and you say I said the opposite of what I said.. never shall the two mean the same thing no matter how hard you try.. round hole square peg and all that. And science, you know, impartial observation, which you seem incapable of making, be damned.

As to the ‘noise’ the waves make.. when I was remodeling the basement of the CFHT, and keep in mind this is a long time ago, Gus’ brother still worked at HVO so there might have been some technical help from that quarter, but regardless, I was shown studies of seismic events being recorded.. some were predictable.. vibration of a pump or some such machinery elsewhere in the building, and then some were random and eventually it was figured out that a good bunch of the random vibrations came and went with the wave sets that broke against the islands. Back then the effort was to isolate the inner pad of the foundation that the scope sits on from vibrations coming from and through the outer ring that the dome and the rest of the facility’s infrastructure sits on. But the resolution, the amplitude, of the ‘noise’ they were trying to identify and stop was at the same level as the noise from the coastline.

But hey, don't worry your little head about it. Obviously all this is outside your wheelhouse. Beyond the scope of your comprehension. And still, no matter, all’s to the good.
