Volcanic ash in Northern Hemisphere

[Liz]

Jusy heard (again on the telly) that flights out of Brisbane to some parts of Europe, have been cancelled due to volcanic ash in the atmosphere.
Hope its stays in N.Hemisphere. If it does somehow manage to find its way south, we can blame Alex (Mental4Astro) as he mentioned that he has finished building his Dob, and hoping that a volcanic eruption didnt occur to obscure his views of the nigth sky. ;)

Liz,

my highly informed, well researched and internationally acclaimed opinion ;) is that it won't cross the tropics. I doubt that much will even get into the northern sub-tropics. (David now waits for mud - or volcanic ash - on his face.)

looks like another BIRD strike :lol::lol::lol:

amazing

I am about to throw the first mud pie:lol:
Mt Pinatubu in 1991, this from Wiki:D

The effects of the eruption were felt worldwide. It ejected roughly 10 billion metric tonnes (10 cubic kilometres) of magma, and 20 million tons of SO2 (http://en.wikipedia.org/wiki/Sulfur_dioxide), bringing vast quantities of minerals and metals to the surface environment. It injected large amounts of aerosols (http://en.wikipedia.org/wiki/Particulate) into the stratosphere (http://en.wikipedia.org/wiki/Stratosphere)—more than any eruption since that of Krakatoa (http://en.wikipedia.org/wiki/Krakatoa) in 1883. Over the following months, the aerosols formed a global layer of sulfuric acid (http://en.wikipedia.org/wiki/Sulfuric_acid) haze. Global temperatures dropped by about 0.5 °C (http://en.wikipedia.org/wiki/Celsius) (0.9 °F (http://en.wikipedia.org/wiki/Fahrenheit)), and ozone (http://en.wikipedia.org/wiki/Ozone) depletion temporarily increased substantially.[6] (http://en.wikipedia.org/wiki/Mount_Pinatubo#cite_note-5)

A volcanolagist on the BBC radio said there is every possability of the volcano continuing spewing ash for anything upto six month:eyepop:
Cheers

And I thought the impeding arrival of my SDM only bought clouds. Whoops.

This puts it all in perspective:eyepop:

Certainly interesting to keep an eye on. :shrug:
Hopefully not too much ash down under, as I am about to tackle the Argo Navis that I've had for a few months. Not new though, so its not me, if it does venture south.

The ones we have to worry about are on Vanuatu....some of the volcanoes there are spewing gas and ash right now and they're primed for a large eruption at some stage. Considering the type of volcanoes they are (Island Arc type....acidic volcanism), if one of them decided to do a Krakatoa or Tambora, we'd be in trouble. The tsunamis would hit our coast within a couple of hours...the reef would be no real protection. It might cut down on the initial severity of the tsunamis, but it wouldn't prevent the flooding from occurring.
