I've been looking at the mechanics of volcanoes, with a view to

Apart from the new branch of science inerted on the ne'er do wells,
there is a long way to go yet.

Bernard Choett reminds me of that Indian who has the home made solar
observatory in Coimbatore. Fantastic results but limited grasp of
cause.

In the Horizon programme he made about Popakettleon following his
discovery about the Nevada Del Ruis(?) eruption he mentions that Long
Period Events or B harmonics can be used to forecast accuratley the
eruptions of volcanoes.

He swrongly attributes the A tone to rocks breaking and magma
progress.

Fair play there is precious little to go on, I admit. And even though
wrong his discoveries make him one of the richest men in the world. So
I cast no aspersions on a man god is blessing.

However I was thinking along the lines of Helmholtz resonation. Prof
Choett uses the analogy of an organ pipe in his explanation of B
tomes. But in a volcano about to erupt, the cavity is usually sealed.

Someone in the days of conical galss pop bottles, told me that a
bottle of lemonade with a 4" nail in it would explode before long if
it was put in a car boot and taken somewhere. (I can't remember why he
would have wanted to find that out but I believed him.)

So why would it blow?

Why would a volcano blow in any case? There is always a vent or two
open with them or ellse the alternative science of measuring gass
evolution would have never been tried.

What make the chamber resonate when closed rather than when open?

Is it that an open volcano is liable to be neutralised by the wind
blowing across its calderon?
That would be an effect of Helmholtz Resonators used in car exhaust
pipes.

Just this minute I looked up supercritical fluids and found something
more to confound me:

http://en.wikipedia.org/wiki/Supercritical_fluid

Apparently they can make short work of solids. But how much more so
when activated by the frequencies of bad weather or whatever the
weather that seems to affect them. (Allowing for the probability that
they all have different frequencies and react accordingly to different
weather.)

It seems that a long period of anticyclonic weather in the UK thus
over the NE North Atlantic (a Blocking High) is causative for a lot of
Icelandic vulcanicity.

Someone tell me if the anticyclonic stuff extended right through the
atmosphere. I only followed the charts adjusted for mean sea level.

There is a smoker in the region Bjorn Soerheim was posting about a few
months back. That was interesting. And it all seems to bear out what
Thomas Gold was saying all those lost years ago.
I wonder what its activity periods suggest.

Some research on that will yield interesting results for anyone
interested in why the weather stalls on the Mid Atlantic Ridge. (There
now follows a long/very long/long, long, very long... break on behalf
of the Thatcherism Party, whilst someone passes the hat.)

Sometimes we hit the bear and sometimes the bear hits us. But whatever
is held true at any time, the absolute truth will eventually become
the mainstream. That at least is a constant.

(As a PS

Prof or Doctor (or whatever he is) Choett is still pondering what
causes the long period events. Shall I write and tell him?

It appears logical to me; though there are those who think I am
punching below their wait.
With the top off, the cavity doesn't resonate with a full harmonic
wave.
With the top screwed on it blows.
How can it blow?
Where is the gas coming from?
It could vent at will prior to the dome forming. How come there is
still gas to go?

clean up the post a bit an submit it to as many scientist as possible.
