Big deal. Give me scribes and pharsicals any day.

No, what I am really interested in is cause and effect, not farts from
the past.

Take for example the coffee cup effect of volcanics:

"The ear, has a settling time. It cannot perceive pitch unless a tone
persists for some minimum duration. For example, a 100Hz tone must
persist 0.04 seconds, or 4 cycles, before we discern its pitch. A tone
of 1000Hz must persist for about 0.013 seconds, or for about 13 cycles.
Lesser persistence sounds more like a click, scratch, static, or
something, but not a pure tone. So, the pitch that an oscilloscope
displays is not necessarily what an ear hears."

Now convert that to the pictures a siesmograph displays when an
earthquake occurs. A lump of rock so many miles underground is the
focal point of what the geologists spit consider the epicentre.

Wherever it really is, the chances are that it contains ...within how
many acres of strata ... so much trapped gas. Given the temperatures
and pressures involved under certain circumstances, we know that some
of that rock liquidises and reaches a state at which a certain harmonic
affects it.

(Think pietzo-electrics if you are stymied with the intelect of a
Yawnrence Junkforbrains or a ****head Silly.)

For all we know, when the NAO reaches a certain pitch all this trapped
gas is aggressively attacked by the seismic waves ordinarily released
as earthquakes.

The rest is natural history.

Who can say different?
Speak up.

Welsh or USAan I don't give a stuff for the dimwits that would have me
silenced. No more than that fairy with the silly ideas about lunar
phases all being the same.

I couldn't care less about them. This is usenet. If you can't argue
with facts I suppose you are free to argue personalities. I have one of
them. All others bow before me. Especially dimwits like the two
aforesaid thickos.

I am either right or wrong whatever they say. As it happens, every time
I have been wrong so far this year, I have managed to learn a lot more
than they will ever know -if you measure their complete knowledges
between them.

So on with it all I say. Ignore me and/or abuse me at your peril, not
mine.

It's not hard.
Not at 600 degrees Centigrade it ain't:

If a glass cylinder is filled nearly completely with water and tapped
on the bottom, one can detect the lowest longitudinal mode of the water
column, for which the height of the water column is one-quarter
wavelength.

If the cylinder is rapidly filled with hot tap water containing
dissolved air, the pitch of that mode may descend by nearly three
octaves during the first few seconds as the air comes out of solution
and forms bubbles.

Then the pitch gradually rises as the bubbles float to the top..
