    Thousands of villagers began fleeing their homes in the path of red-hot lava flows oozing from Indonesia's Mount Merapi today as officials said an eruption looked imminent.

    Nightmare for the residents.
    These are the sorts of events that must be the fly in the ointment for models like Noseys I guess.

    if the eruption takes place "imminently", what effect would this have on our winter weather patterns [​IMG]

    It depends on the type of eruption and its composition. If it's mainly continuous lava flow, it will not have any impact on the weather.

    If it is a highly explosive eruption, with a lot of fine ash particles, it could have quite a lot of impact. This effect depends on how small the particles are and how high into the atmosphere they go.

    because of the tectonic qualities of that part of the world there is a greater liklihood of a major eruption producing high atmospheric aerosols. it's a matter of scale. That is quite a cone that sucker has got.

    I remember in the early nineties 90-91 i think, a big volcano in the phillipines blew! It was a fact that it did have a cooling effect on southern australias weather. Maybe thats why we had huge snow season those years..

    This volcano is closer than the one in the philippines. Maybe it will effect our weather if it blows its top

    that was pinatubo, and it was one of the biggest erruptions of recent times, I just remember the sunsets for months after that, the colours were just jaw dropping.

    Pinatubo gave 1991 and 1992 ski seasons a real boost as did Agung (Bali) in the mid sixties. Being near the equator gives good distribution of the aerosols.

    Basically it is cooling effect so less rain events.

    I think if you knew what a major eruption could actually do to the earth then you wouldn't say that. It has the potential to kill billons of people and change the world as we know it.The scientists have called them super eruptions. There was a good movie not long ago showing what would happen if yellowstone park blew its top.

    I have seen a few on Mt St Helena. Foxtel have some good docos. It was amazing how it melted its glacier and that turned into one massive wave that destroyed everything in its path. I think the volcano movie was on the ABC so you might be able to find it.

    that movie about yellowstone was crap. factually meaningless.

    It started off with good intentions but like so many before and no doubt many to follow fell victim to the majority of the budget being spent on "ground breaking visual technology" rather than factual accuracy. hell if my memory serves me correctly i think they mingled a suttle love story into this "breakthrough doccumentry"

    oh well.
    thats what grinds my gears this week.

    Why wont more volcanoes take foot in australia and give us decent mountains. im not asking ofr the himalayas or anything, a 10,000ft peak or two would be nice. what is cozzie? 6500 or something....? werent they gonna build a tower in mildura that was half that height?

    the movie is called super volcano done by BBC, I actually bought it as i thought it was great (plus i am a self confessed doco geek, i also bought space odyssey, voyage to the planets).
    Its quite daunting and amkes you sit up and take notice of the actual effects. very scary stuff.

    When you drive up the mountain next to Mt St Helens, it's quite mindblowing to see all the tree trunks lying on the ground all perfectly aligned pointing from the eruption - and that's for miles and miles around. Must have been one hell of a blast.

    So are we seeing a 'major' eruption yet?

    Any news sources to confirm a 'major' eruption?

    I have next to no clue about volcanic effects on the earths weather patterns, how immediate are impacts on our weather. I would imagine it could potentially change systems within a week or so.

    Just wondering - how long (ball park figure - weeks/months) at this time of year does it take for the ash to meander its way down here and start affecting our climate/weather?

    EDIT: Damnit I'm slow! I always do that, hit the reply button then start looking at somehting else - only to finaly reply and look like a fool when osmeone beats me by heaps! [​IMG]

    I remember reading somewhere that volcanoes near the equator have a biger effect on weather cause there is better dispersal of ash in the atmosphere. The ash itself I think blocks out solar radiation causing cooling in the lower atmosphere.

    Pinatubo in the early 1990's caused a measurable drop in the earths surface temperature. I've seen the data presented before in the weather forum but can't remember where. The Pinatubo eruption though was HUGE so this one porbably far less likely to have an affect. I'm guessing about most of this though

    Here's a link which briefly describes the effect of the pinatubo erruption

    Looks like we need one to go up like April 1815 - lowered global temps by 3celcius [​IMG]

    That was Tambora. It caused the "summer without summer".

    To put the Pinatubo eruption into some context, the Tambora eruption of 1815 ejected around 100 cubic km of material ("the summer without summer"), Mt St. Helens in 1980 ejected 1.2 cubic km, while Pinatubo ejected around 10 cubic km of material in 1991. Krakatoa(Indonesia) ejected around 18-21 cubic km of material in 1883.

    Other eruptions of a cataclysmic nature were Yellowstone (2.2.million years) ejecting 2500 cubic km of material and Toba (in Indonesia) ejecting 2800 cubic km 74,000 years ago.

    Santorini in about 1450 BC was a nice big one too. Not as big as Yellowstone or Toba, but right up there as far as modern eruptions go.

    Pinatubo coincided with a typhoon causing more localised damage to the country. Like pouring concrete over the area.

    74,000 years ago - wasn't that the start of the last "mini ice age"? Could this event have triggered it?

    Are there any predictions of what this current indonesian volcano could throw up - or is it more a "wait and see" thing?

    Toba in Sumatra experienced the massive super volcano 74,000 years back.

    The deep Java trench marks the line where the Indo-Australian plate subducts, i.e. slips under, the section of the Eurasian plate on which Indonesia sits.

    According to computer models, somewhere near Toba, another super volcano is getting ready for eruption. 3.1 mile sinking of Indo-Australian plate under the Eurasian Plate in the last 74,000 years has created enough magma for a super volcano.

    Could a super be building? Could be super for snow - but that would be about it! Probably even freak our crops out - but it is all part of the natural cycle.

    An Australian expert has warned that Indonesia faces the prospect of a "super volcano" eruption that would dwarf all previous catastrophes.

    Prof Ray Cas of Monash University's School of Geosciences said the world's biggest super volcano is Lake Toba, on Indonesia's island of Sumatra, site of both the massive earthquakes.

    Those quakes occurred along fault lines running just off Sumatra's west coast and created seismological stresses that could hasten an eruption.

    Cas said Toba last erupted 73 000 years ago in an event so massive that it altered the entire world's climate.

    "The eruption released 1 000 cubic kilometres of ash and rock debris into the atmosphere, much of it as fine ash which blocked out solar radiation, kicking the world back into an ice age," he said.

    The scientist said super volcanoes represented the greatest potential hazard on earth, "the only greater threat being an asteroid impact from space".

    don't want to get involved with volcano envy here, but Lake Taupo was sizeable in 181AD with 35 cubic km

    OK - next time, and yes that would have been some explosion there on the Nth Is.

    And guess what - I have just crackedatoe - aarrgh! Little one on the right foot 24 days out from season 06!

    Ah, I found it.
    "Pyroclastic flows could spread to a radius of between 8 kilometers and 12 kilometers in coming days, Subandrio, head of the Mount Merapi observatory at the center, said on May 13".

    Well done Taipan I think you willed this to happen [​IMG]

    In reference to Pinatubo and when things started to cool down. It started to erupt in May 1991, climaxing in June.

    I think the good ski season of 1991 was a coincidence as it wasn't an especially cold winter, just zonal with alot of active fronts inbetween. The exception was August ( here in Tasmania ) which was phenonomal for the amount of snow received. It was also very cold.

    I think the cooling came into affect from about December, that's a 6 month lag time, and continued thru much of 1992 ( giving a very cold winter in southern Australia, which boosted the ski-season in that year ).
