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. mark |

The reason is that it contains lots of useful trace elements. Regards, Nick Maclaren. |

Slightly too much of some of them. It is fine as a moderate dusting but bad in excessively large amounts and at short range. Like most things, even water. 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. 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. Regards, Nick Maclaren. |

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! :-) http://www.flightradar24.com/ |

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. Tina No smell |

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. Regards, Nick Maclaren. |

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.

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. Regards, Nick Maclaren. |
