Volcanic Dust
 

Just been and had a sniff.
No smell of sulphur detected here in Norfolk or any volcanic dust. Bright,
sunny, clouds with about a third blue sky.

You know that it's excellent fertiliser?

I didn't. Presumably if it is dark the ground will warm up and be of benefit
to plants.

It won't be that heavy, from the sound of it, except perhaps up
in Shetland.

The reason is that it contains lots of useful trace elements.

Slightly too much of some of them. It is fine as a moderate dusting but
bad in excessively large amounts and at short range.

Most notably sulphur dioxide and soluble fluorides in volcanic ash are a
real problem in Iceland itself and can cause crop failures and devastate
agriculture. As also happened in Europe when Laki went pop.

It could be very nasty if as expected the bigger badder Katla erupts.

Like most things, even water.

For a year or so, yes. Iceland isn't a major source of worry on a
global scale, though. Consider what would happen if Yellowstone
went up (it's due, though dormant) or something on that scale.

There's a deathly hush here. Perhaps it has something to do with closed
airports.

Now you mention it, I have not seen or heard any planes for ages. They
usually wake me up every few minutes.

Have you seen the radar website of all the planes? It's really fun to
watch! :-)

Cloudy all day here in Leics but only 5C at 11.30 a.m. No sulphur smell but
a dramatic reduction in temperature since yesterday.

When Hekla erupted in 1963, it covered an extensive area of Iceland with
ash which was so high in fluorides that it poisoned large numbers of
sheep and cattle :-(

Even fertilisers are toxic in excess. Iron is a classic one for
plants - animals are even more sensitive.

Indeed, but in this instance we neither have control over what's in the
dust nor how much lands, just as the Icelanders didn't in 1970 (it was
that year I now recall that the fluoride was expelled not 1963). It
shouldn't necessarily be regarded as "excellent fertiliser".

Most of this country (perhaps all) is short of fluorides. If the
ash is dense enough here to cause toxicity, we will have a global
winter on our hands and more serious things to worry about. With
the possible exception of Shetland and the VERY far north.

There could be matters of greater concern on the horizon (assuming they
are visible!).

Precisely. And, even if the wind is towards us, the ash STILL won't
be dense enough to cause significant (or any?) toxicity. The acid
rain may kill trees, as someone else pointed out, but that will be
a different and shorter-term effect.

Oh, and it's not Yellowstone that I should have mentioned: it's Long
Valley (Mammoth Lakes). Smaller than Yellowstone, but has been
twitching for 30+ years - including a 2' change in the level of the
valley floor! Still, I can view an event that might take out Las
Vegas as having a positive side.
