I gathered some videos.

Feel free to chip in.

I saw it fit as half of Europe is a no fly zone now.

The second eruption in Eyjafjallajökull is a different beast. Under a glacier its much more explosive.

Some nice infrared cam in this one. Seeing through the clouds.

Iceland has a high concentration of active volcanoes due to unique geological conditions. The island has about 130 volcanic mountains, of which 18 have erupted since the settlement of Iceland. Over the past 500 years, Iceland's volcanoes have erupted a third of the total global lava output.[1] Although the Laki eruption in 1783 had the largest eruption of lava in the last 500 years, the Eldgjá eruption of 934 AD and other Holocene eruptions were even larger.

Geologists explain this high concentration of volcanic activity as being due to a combination of the island's position on the Mid-Atlantic Ridge and a volcanic hotspot underneath the island. The island sits astride the boundary between the Eurasian and North American Plates, and most volcanic activity is concentrated along the plate boundary, which runs across the island from the south-west to the north-east of the island. Some volcanic activity occurs offshore, especially off the southern coast. This includes wholly submerged submarine volcanoes and even newly formed volcanic islands such as Surtsey and Jólnir.

The most recent[update] volcanic eruption in Iceland was that of Eyjafjallajökull, which started on April 14, 2010. The Eyjafjallajökull eruption closely followed an eruption in Fimmvörðuháls, which had erupted on March 20 and ended April 12.

Icelandic farmers stay put, despite fear of volcanic floods

An ash-covered farm near the disaster zone.

Since ash spewed by Iceland's volcano eruption began causing havoc in northern Europe, the island itself has been largely forgotten. Local farmers there are still in danger however. Hundreds of nearby residents continue to be evacuated, leaving the farming region almost deserted. A farmer from the area gives us her account.

The heat of the eruption in the early hours of Wednesday morning caused a third of the Eyjafjallajokull glacier, upon which the volcano sits, to shift down the mountain, prompting huge floods. The island's circular Road 1, which passes by the area in the south of the island, has been partially destroyed at the point where it crosses the river feed which is carrying the glacier downstream.

The Þjóðvegur 1 (road n°1) was cut in several places and the bridges have been destroyed. Image posted by Julien Oberlé, on his blog, Jujux á Íslandi.

“If the roads aren’t repaired soon, we will have to throw away our milk”

Hanna Lara Andrews is one of the dairy farmers from below the Eyjafjallajokull glacier.

We've been evacuated a few times now [since the first eruption almost a month ago]. This time it was on Wednesday night. A civil protection official phoned us at two in the morning and we got into our shelter. There were then two floods, but they've been able to contain them so far. I managed to get to Reykjavik, where my son is, last night.

Some people stayed behind; my partner and my mother-in-law included. They're 700 km away, underneath the volcano. Farmers are allowed to return to their farms to tend to the animals. They're allowed to go outside during the day, but at night they have to stay in the shelter with the door locked. They're very busy, looking after the animals, protecting the machines from damage [from the ash]. For the time being the livestock seem ok, even if they aren't able to go outside. The ash isn't good in terms of health. The biggest problem is that the roads have been destroyed so the milk can't be collected. We can only stock a certain amount on the farm; if the roads aren't repaired soon, we will have to throw it away.

The ash is still falling thickly; it's difficult to see through it. But it could change direction for the north, which would move it away from the farms. Our biggest fear is the floods. They could come at any moment. Our land hasn't been damaged yet, but some of our neighbours' has."

That really is a stunning image.

I take it all the particulate in the air is what makes for those lightning strikes?

[Agathor]

Yea thats a part of it. I think its just the massive ash cloud acting like a tropical thunder storm.
Alot of up draft into the stratosphere.

From 00:00 to 04:00 last night the volcano was extra explosive. The mountain
was a light with lightning.

Last time it erupted in 1821 , it lasted 2 years. Reaching it maximum outburst 6 months
after it started. History tells us also that Katla always wakes up to when this volcano starts to spew.
Katla is alot bigger and meaner. Eyjafjallajökull is really a nice and well behaved volcano compared
with most others.


Here is a live webcam that is pointed at the mountain.

The volcano has calmed down abit.

[Alex Clomsaver]

This eruption is clearly one of the unpredictable side-effects of manmade climate change. Just like hurricane Katrina and the southern drought!

[RansomList]

Ash so thick the clouds look like a mountain.

[Vinata]

This eruption rules because it may actually lower temperatures a bit. It won't be by much, but every bit helps.

[Malaclypse]

I'm not an expert but I think that statement (not yours but the general assumption) is a great hoax. I mean, it's not the first vulcano to errupt in our lifetime, is it. Lowering average temp by 1°C sounds like hoghwash.

[Vinata]

It isn't the first volcano explosion, but it is a very large one. I don't know enough about volcano eruptions to know if this is one of those big ones, but it is the biggest I've seen.

FakeEdit: I was thinking more along the lines of 1F.

FakeEdit: I was thinking more along the lines of 1F.

Well, they saying 1°C around here. 1°F sounds more realistic but even then... In terms of average planetary temperature that's quite an impact. I'd guess it's more hyped because of the "felt" impact it has, i.e. in terms of shutting down Europe's airtraffic. Imho most bigger eruptions in recent years happened somewhere deep on islands in the Pacific. That affects the islands around the vulcano but obviously the economic and logistic impact is way lower than what we have now. It's not that I doubt the particles (which are vulcanic glas to a big degree) can reflect enough sunlight and thus warmth to have an impact. I yet just don't buy it this one has. But well, as stated, I'm no expert, so I'll glady be corrected.

[Alex Clomsaver]

There've been bigger but as Mala said they were all in the south Pacific or Alaska and didn't effect much of anyone.

[xutech]

Ash clouds near the poles are quickly dissipated due to moving air currents. The equatorial volcano eruptions are the ones which work best for climate alteration, they can last for months or even years.

Forced climate control is one scientific theory for coping with climate change and pollution. The problem is that there can be unexpected side effects. Other options include dropping iron into the ocean to feed algae blooms and several other drastic measures.

[Alex Clomsaver]

When comparing recent volcanos I guess the latest big one would be Pinetubo, most famous for taking out a naval basel.

[RansomList]

dropping iron into the ocean to feed algae blooms and several other drastic measures.

If anyone actually tries this on a mass scale they are retarded.

[Mr Coloredshirt]

The volcano is melting the ice cap surrounding it, how will that help against global warming melting the ice caps?

[Malaclypse]

The volcano is melting the ice cap surrounding it, how will that help against global warming melting the ice caps?

That even has less effect than the ash cloud. Greenland's iceshelter is of mentionable note for the amount and size, Iceland glaciers on their own aren't. Stop panicking.

[Agathor]

For the first 3 days the volcano spewed 750 tons of lava per sek.

95% of that got explosively pulverized to ash similar to talcum powder.
The 5% left plus parts of the mountain and glacier ran down the mountain in a
glacier flood.

All in all its a small volcano , compared to many others.
Its just the prevailing winds and lack of rain to clean the air that is
causing so much havoc. Plus its calming down now. So Europe can relax.

Katla can be 100 times as powerful.
Laki can be 1000 times as powerful.

But there is no guaranty they will cause as much havoc. The weather could be different.
Sending the ash north or raining down somewhere in the Atlantic.

Laki is prop the only one that really change the climate.
I am gonna remind you that Eyjafjallajökull has 3 main main fissures now.

Laki or Lakagígar (Craters of Laki) is a volcanic fissure situated in the south of Iceland, not far from the canyon of Eldgjá and the small town Kirkjubæjarklaustur, in Skaftafell National Park.

Laki is part of a volcanic system, centering on the Grímsvötn volcano and including the Thórdarhyrna volcano.[1][2][3] It lies between the glaciers of Mýrdalsjökull and Vatnajökull, in an area of fissures which run in a south-west to north-east direction.

The system erupted over an 8 month period during 1783-1784 from the Laki fissure and the adjoining Grímsvötn volcano, pouring out an estimated 14 km3 (3.4 cu mi) of basalt lava and clouds of poisonous hydrofluoric acid/sulfur-dioxide compounds that killed over 50% of Iceland's livestock population, leading to famine which killed approximately 25%[4] of the population.

On 8 June 1783, a fissure with 130 craters opened with phreatomagmatic explosions because of the groundwater interacting with the rising basalt magma. These are sometimes mistaken by non-volcanologists as being "Plinian"[citation needed] but are not. Over a few days the eruptions became less explosive, Strombolian, and later Hawaiian in character, with high rates of lava effusion. This event is rated as VEI 6 on the Volcanic Explosivity Index, but the eight month emission of sulfuric aerosols resulted in one of the most important climatic and socially repercussive events of the last millennium.[5]

The eruption, also known as the Skaftáreldar ("Skaftá river fires") or Síðueldur, produced an estimated 14 km3 (3.4 cu mi) of basalt lava, and the total volume of tephra emitted was 0.91 km3 (0.2 cu mi).[1] Lava fountains were estimated to have reached heights of 800-1400 m (~2,600-4,600 ft). In Great Britain, the summer of 1783 was known as the "sand-summer" due to ash fallout.[6] The gases were carried by the convective eruption column to altitudes of about 15 kilometres (10 mi). .

The eruption continued until 7 February 1784, but most of the lava was erupted in the first five months. Grímsvötn volcano, from which the Laki fissure extends, was also erupting at the time from 1783 until 1785. The outpouring of gases, including an estimated 8 million tons of hydrogen fluoride and estimated 120 million tons of sulfur dioxide, gave rise to what has since become known as the "Laki haze" across Europe.

he consequences for Iceland—known as the Mist Hardships—were catastrophic.[7] An estimated 20-25% of the population died in the famine and fluorine poisoning after the fissure eruptions ceased. Around 80% of sheep, 50% of cattle and 50% of horses died because of dental and skeletal fluorosis from the 8 million tons of hydrogen fluoride that were released.[6][8]

The parish priest Jón Steingrímsson grew famous because of his eldmessa ("fire sermon"). The people of the small town of Kirkjubæjarklaustur were worshipping while the town was endangered by a lava stream, which ceased to flow not far from town, with the townsfolk still in church..

"This past week, and the two prior to it, more poison fell from the sky than words can describe: ash, volcanic hairs, rain full of sulfur and saltpeter, all of it mixed with sand. The snouts, nostrils, and feet of livestock grazing or walking on the grass turned bright yellow and raw. All water went tepid and light blue in color and gravel slides turned gray. All the earth's plants burned, withered and turned gray, one after another, as the fire increased and neared the settlements."[9]

An estimated 120 million tons of sulfur dioxide were emitted, approximately equivalent to three times the total annual European industrial output in 2006, and also equivalent to a Mount Pinatubo-1991 eruption every three days.[6] This outpouring of sulfur dioxide during unusual weather conditions caused a thick haze to spread across western Europe, resulting in many thousands of deaths throughout 1783 and the winter of 1784.

The summer of 1783 was the hottest on record[citation needed] and a rare high pressure zone over Iceland caused the winds to blow to the south-east. The poisonous cloud drifted to Bergen in Norway, then spread to Prague in the Province of Bohemia by 17 June, Berlin by 18 June, Paris by 20 June, Le Havre by 22 June, and to Great Britain by 23 June. The fog was so thick that boats stayed in port, unable to navigate, and the sun was described as "blood coloured".[6]

Inhaling sulfur dioxide gas causes victims to choke as their internal soft tissue swells. The local death rate in Chartres was up by 5% during August and September, with over 40 dead. In Great Britain, the records show that the additional deaths were outdoor workers, and perhaps 2-3 times above the normal rate in Bedfordshire, Lincolnshire and the east coast. It has been estimated that 23,000 British people died from the poisoning.[10]

The haze also heated up, causing severe thunderstorms with hailstones that were reported to have killed cattle, until it dissipated in the autumn. This disruption then led to a most severe winter in 1784, in which Gilbert White at Selborne in Hampshire reported 28 days of continuous frost. The extreme winter is estimated to have caused 8,000 additional deaths in the UK. In the spring thaw, Germany and Central Europe then reported severe flood damage.[6]

The meteorological impact of Laki resonated on, contributing significantly to several years of extreme weather in Europe. In France a sequence of extremes included a surplus harvest in 1785 that caused poverty for rural workers, accompanied by droughts and bad winters and summers, including a violent hailstorm in 1788 that destroyed crops. This in turn contributed significantly to the build up of poverty and famine that may have contributed to the French Revolution in 1789. Laki was only a factor in a decade of climatic disruption, as Grímsvötn was erupting from 1783–1785 and a recent study of El Niño patterns also suggests an unusually strong El-Niño effect from 1789-93.[11]

In North America, the winter of 1784 was the longest and one of the coldest on record. It was the longest period of below-zero temperatures in New England, the largest accumulation of snow in New Jersey, and the longest freezing over of the Chesapeake Bay. There was ice skating in Charleston Harbor, a huge snowstorm hit the south, the Mississippi River froze at New Orleans, and there was ice in the Gulf of Mexico.[12][13]

There is also evidence that the Laki eruption had effects beyond Europe, with weakened African and Indian monsoon circulations, leading to precipitation anomalies of -1 to -3 mm (-0.04 to -0.12 inch) a day over the Sahel of Africa, resulting in, among other effects, low flow in the River Nile.[14] The famine that afflicted Egypt in 1784 cost it roughly one-sixth of its population.[15] It may also have exacerbated the Tenmei famine in Japan.

Gilbert White recorded his perceptions of the event at Selborne:

The summer of the year 1783 was an amazing and portentous one, and full of horrible phaenomena; for besides the alarming meteors and tremendous thunder-storms that affrighted and distressed the different counties of this kingdom, the peculiar haze, or smokey fog, that prevailed for many weeks in this island, and in every part of Europe, and even beyond its limits, was a most extraordinary appearance, unlike anything known within the memory of man. By my journal I find that I had noticed this strange occurrence from June 23 to July 20 inclusive, during which period the wind varied to every quarter without making any alteration in the air. The sun, at noon, looked as blank as a clouded moon, and shed a rust- coloured ferruginous light on the ground, and floors of rooms; but was particularly lurid and blood-coloured at rising and setting. All the time the heat was so intense that butchers' meat could hardly be eaten on the day after it was killed; and the flies swarmed so in the lanes and hedges that they rendered the horses half frantic, and riding irksome. The country people began to look with a superstitious awe, at the red, louring aspect of the sun; [...][16]

Benjamin Franklin recorded his observations in a 1784 lecture:

During several of the summer months of the year 1783, when the effect of the sun's rays to heat the earth in these northern regions should have been greater, there existed a constant fog over all Europe, and a great part of North America. This fog was of a permanent nature; it was dry, and the rays of the sun seemed to have little effect towards dissipating it, as they easily do a moist fog, arising from water. They were indeed rendered so faint in passing through it, that when collected in the focus of a burning glass they would scarce kindle brown paper. Of course, their summer effect in heating the Earth was exceedingly diminished. Hence the surface was early frozen. Hence the first snows remained on it unmelted, and received continual additions. Hence the air was more chilled, and the winds more severely cold. Hence perhaps the winter of 1783-4 was more severe than any that had happened for many years.

The cause of this universal fog is not yet ascertained [...] or whether it was the vast quantity of smoke, long continuing, to issue during the summer from Hecla in Iceland, and that other volcano which arose out of the sea near that island, which smoke might be spread by various winds, over the northern part of the world, is yet uncertain.[17] (According to contemporary records, Hekla did not erupt in 1783; its previous eruption was in 1766. The Laki fissure eruption was 45 miles (72 km)[18] to the east and the Grímsvötn volcano was erupting circa 75 miles (121 km)[19] north east. Additionally Katla, only 31 miles (50 km)[20] south east, was still renowned after its spectacular eruption 28 years earlier in 1755.)

The Reverend Sir John Cullum of Bury St Edmunds, Suffolk, Great Britain recorded on the 23rd June 1783, the same date that Gilbert White noted the beginning of the unusual atmospheric phenomena, in a letter to Sir Joseph Banks, then President of The Royal Society

...‘about six o’clock, that morning, I observed the air very much condensed in my chamber-window; and, upon getting up, was informed by a tenant that finding himself cold in bed, about three o’clock in the morning, he looked out at his window, and to his great surprise saw the ground covered with a white frost: and I was assured that two men at Barton, about three miles (5 km) off, saw in some shallow tubs, ice of the thickness of a crown-piece.’[21]

Sir John goes on to describe the effect of this ‘frost’ on trees and crops:

‘The aristae[22] of the barley, which was coming into ear, became brown and withered at their extremities, as did the leaves of the oats; the rye had the appearance of being mildewed; so that the farmers were alarmed for those crops…The larch, Weymouth pine, and hardy Scotch fir, had the tips of their leaves withered’.[21]

Sir John’s vegetable garden did not escape either, for he noted that they appeared ‘exactly as if a fire had been lighted near them, that had shrivelled and discoloured their leaves’.

Eliza Geirsdottir Newman: Eyjafjallajokull

Eyjafjallajokull - pronounced ay-uh-fyat-luh-yoe-kuutl-ul - is the name of the Icelandic volcano that threw up plumes of ash clouds causing airspaces across Europe to close down. Eliza Geirsdottir Newman, an Icelandic musician, sang an exclusive song to Al Jazeera to help clarify the word's correct pronunciation. The video includes a bouncing ball to help karaoke singers pronounce the volcano's name. [April 19, 2010]

What we want is southerly wind. Blow that shit out to the sea. Seems that will go as planned until thursday
then will turn to the east. Everything is better then westerly winds, then Reykjavik will get spared.

The met guys say its 10 times bigger the Eyjafjallajökull eruption.
But it does not have the very fine talcum powder like ash. So thats a plus.

So its putting out around 7500 tons of lava per sek, the plume is strange
as it is segmented. Under 3 km it is heading south, over 10 km its
mushrooming out and heading to the north.
