Quote:
Thousands of villagers living on the slopes of an Indonesian volcano fled the area after authorities issued a "red alert " on Saturday, warning that a full-scale eruption appeared imminent.

Merapi, which is on Java Island about 400 kilometres southeast of Jakarta, rumbled back to life three weeks earlier, belching clouds of black ash and oozing fiery lava....

There is a lot of information about Merapi on the Internet; and wiki says it is one of 16 Decade Volcanoes:
Quote:
The Decade Volcanoes are 16 volcanoes identified by the International Association of Volcanology and Chemistry of the Earth's Interior (IAVCEI) as being worthy of particular study in light of their history of large, destructive eruptions and proximity to populated areas. The Decade Volcanoes project encourages studies and public-awareness activities at these volcanoes, with the aim of achieving a better understanding of the volcanoes and the dangers they present, and thus being able to reduce the severity of natural disasters. The project was initiated as part of the United Nations-sponsored International Decade for Natural Disaster Reduction...

Krakatoa, east of Java ...

God bless those people, especially the ones who won't leave without their animals. God bless the animals.

Speaking as a nerd and pendant... Confused Krakatoa is actually west of Java. The movie was based on a book that had it wrong. I learned that from Simon Winchester's book The Day the Earth Exploded. I guess the main difference though, is that Krakatoa blew itself up and caused a tsunami, but Merapi is likely to cause other kinds of local destruction: gases, lava, etc. I don't know if a tsunami would be expected.

Double trouble. Embarassed

ETA: skdadl is concerned in the very next post; but my comment just signifies that I double-posted.

As far as I can tell, the little editing note will not appear; maybe it doesn't unless you edit after quite a while, or after making another post elsewhere, or even not until after the date has changed? My mistake, it did appear.

Ok. Krakatoa, west of Java. As long as we've still got rhythm, I'm willing to revise the details. Wink

What do you mean when you say we've got double trouble? Has something happened?

Alaska's Mount Redoubt Volcano Begins Erupting

Quote:
The shot above (courtesy of AVO/USGS) of the top vent in the Redoubt Summit Crater was taken on Saturday before the eruptions began.

Alaska's Mount Redoubt volcano began erupting on Sunday, Alaska's KTUU reports:

Quote:
Mount Redoubt erupted four times three hours late Sunday and early Monday, and the Alaska Volcano Observatory says the most recent was the largest so far. 'Beginning at 10:38 p.m. (Sunday) night, we began to have explosive activity,' geophysicist John Power with the United States Geological Survey said. 'At this point we have recorded four separate explosive events. These events were very large, explosive eruptions of Redoubt Volcano.' An eruption cloud is estimated to be at 50,000 feet above sea level at present. The National Weather Service has issued an ash fall advisory for the cities of Talkeetna, Willow and Cantwell, effective until 8 a.m. Monday. Ash fall has been reported in Skwentna, and AVO says ash is still being emitted from the volcano. Predictions before the most recent eruption called for light ash fall and for it to miss Anchorage, but things can change rapidly.

"Scientists estimated the plume reached a height of 50,000 feet above sea level. As the ash spread north and northeast, ashfall advisories were issued for communities north of Mt. Redoubt. Geologists warned of the possibility of mudflows and debris avalanches from melting ice on the mountain’s summit."

I guess it's reassuring for you to know that you've got a few extra members of the household who can drive if you have to evacuate. You just have to be careful that they take you with them.

Mount Redoubt Volcano Eruption Inspires Dramatic Lightning Storm

Quote:
Alaska's Mount Redoubt volcano continues to display elevated activity. After several eruptions on Saturday, Anchorage's airport was closed. It has since re-opened. You may remember that in 1989 when Redoubt was having another eruption a KLM 747 dropped 13,000 feet after its engines became filled with ash from the volcano. Luckily it was able to restart two of them and land safely.

Bretwood Higman, who is trekking from Puget Sound to the Bering Sea, snapped the photo above of lightning during an eruption late Friday night. He also produced a time-lapse film during an eruption on Saturday.

Watch: Deepest Erupting Undersea Volcano Ever Observed

Quote:
Scientists have observed and filmed a volcano erupting 4,000 feet below the ocean's surface for the first time ever:

Quote:
A submersible robot witnessed the eruption in May during an underwater expedition near Samoa, and the high-definition videos were presented Thursday at a geophysics conference in San Francisco...Earth and ocean scientists said the eruption allowed them to see for the first time the creation of a material called boninite, which had previously been found only in samples at least a million years old. In the past, boninite lavas had only been found on extinct volcanoes, so researchers were excited to see firsthand how they are created.


Said Joseph Resing, a chemical oceanographer at the University of Washington: "When we got there, we put the sub down, and within in an hour and a half we found an eruption there in its full glory. We haven't seen this before. And now for the very first time, we see molten lava flowing on the sea floor."

How can I make a realistic looking volcano? I am doing a geography project and I have to make a volcano based on Soufriere Hills. It doesnt have to look exactly like it but it would be great if it did. It doesnt have to actually work, and I dont want it to make a mess! What equipment/materials would I need?

This site seems to have fairly good instructions: http://www.mahalo.com/how-to-make-a-model-volcano

If it were me I would probably start with a wire frame to make sure you can have exactly the shape you want. Then I would overlay it with chicken wire or something similar, on top of which I would put papier mache. That should give you the basic shape. You can use the same technique to build smaller hills around it if you want less of a stark, standing by itself, look.

Given that you are working on a fairly active volcano, you probably want green lower slopes and more ashen upper slopes. For the lower slopes you can buy flocking (which is green) at pretty much any modelling supply store to use as a sort of base coat and then use more fluffy green stuff (can't remember what it is called, but the same store should have it) for bushes and small trees. You might want to find small pebbles to use for stones, with the size varying depending on the scale you are working on. Go too small, and it will be really fidgety, but if you go too big it will be a massive project.

For the upper slopes I would suggest using more gravel and perhaps sand to suggest a more barren terrain. Ash is the main feature of the upper slopes of Soufriere Hills, and is generally fairly dark in colour. If you can get a fairly dark sand, that ought to work for ash. You may want to texture it a bit by running drops of water down the sides to get the kind of look that you can see on the slopes of Soufriere Hills.

Given how active Soufriere Hills is, you might want to consider adding smoke to the top. A way you might try doing this is by ripping cotton balls into strands of cotton and then gluing the wispy strands onto bits of wire, and then poking the wire into the top of the volcano. If you have access to a spray bottle, you could try mixing up a very thin mixture of grey paint and water, and then spraying that over the cotton, since that would likely give a pleasing mottling to the "smoke" and make it look more realistic.

Going at it this way may make a bit of a mess in the making of it, but if you are going to make a decent omelet, you really do have to break a few eggs.

Volcano erupts in Icelandic glacier, forcing evacuations

Quote:
... Shortly before midnight, the Eyjafjallajökull glacier, the island's fifth largest, started to spew smoke and lava from several craters along a rift which is popular with hikers.


Eyjafjallajökull?! Try'n say THAT six times fast! Razz

Lovely volcano photography



Quote:
What's better than a volcano? A volcano with the Northern Lights behind it.

Photographer Albert Jakobsson took this awesome shot of Iceland's Eyjafjajokull (gesundheit) volcano. In the full series of photos, you can see Icelanders entertaining themselves by hanging out and roasting hot dogs on the glowing embers of the active, but "lazy", volcano.


What's better than a volcano? Northern Lights shining above a volcano that is so desultory that you can roast weenies over it! Mr. Green

Volcanic Ash Plume Grounds All Air Traffic Over UK, Norway

Quote:
Air traffic in the UK, Norway, and much of Sweden has been closed after an eruption from the Icelandic volcano 10 to 20 times greater than the one last month sent a high-altitude cloud of ash drifting towards France.

The NYT:

Quote:
The move effectively grounded all flights in Britain from 11:00 a.m. GMT (7:00 a.m. EDT) and affected the estimated 6,000 flights using British airspace everyday, aviation experts said. The impact was likely to be among the most severe in many years, cutting transatlantic links and severing air routes across northern Europe. The silence of the skies reminded some aviation experts of the days after the attacks of Sept. 11, 2001, when transatlantic flights were suspended. Since then, aviation in Britain has seen huge disruptions caused by terrorism alerts and industrial unrest.


700 have been evacuated:

Quote:
The eruption under the Eyjafjallajokull glacier - 10 times more powerful than another one nearby last month - showed no sign of abating after more than 24 hours of activity, University of Iceland volcanologist Armannn Hoskuldsson said. "It's becoming more intense, but there will be no lava - this is purely an explosive eruption," he told Reuters. To the east of the volcano, thousands of hectares of land were covered by a thick layer of ash, while a cloud was blotting out the sun in some areas along the southern coast of Iceland, local media reported. Hot fumes from the eruption melted vast amounts of ice on the glacier, Iceland's fifth largest, but flood waters which had caused wide damage to roads and bridges on Wednesday were receding, Hoskuldsson said.


UPDATE: Dutch airspace to close at 7 pm.

Photo: Iceland Volcano Ash Plume As Seen from Space

Quote:
A recent image of the ash plume over the north Atlantic ocean caused by the volcano in Iceland which has shut down air traffic to most of northern Europe. Volcanic ash in a plane's engines becomes molten glass and clogs them, causing complete shutdown.

The dude on "Canada AM" just tried it three times and (doubtlessly) mangled it each time -- all to loud sniggering from the rest of the crew on set.

Maddow didn't try to say it, I was hoping for at least an admission that she wouldn't try because she had no idea and would horribly mangle it. Or get the expert volcanologist guest to give it a try.

Most Anglos can't pronounce it properly - as an Icelandic friend of mine (university buddy) used to say "After ten years of living in Canada whenever I go home my jaw hurts after about an hour from making sounds that I never use when speaking English".

Icelandic is definitely a kooky language. Did you know that their cows don't even moo? An Icelandic moo uses one of those sounds that just doesn't exist in English.

It is also, according to what I've heard and read, one of the most notoriously difficult languages to learn.

According to the article linked below, Eyjafjallajokull is pronounced: ay-yah-FYAH'-plah-yer-kuh-duhl

Disruptions caused by ash cloud worsen, airlines face ruin

Quote:
Thick drifts of volcanic ash blanketed parts of rural Iceland on Friday as a vast, invisible plume of grit drifted over Europe, emptying the skies of planes and sending hundreds of thousands in search of hotel rooms, train tickets or rental cars.

Polish officials worried that the ash cloud could threaten the arrival of world leaders for Sunday's state funeral for President Lech Kaczynski and his wife Maria in the southern city of Krakow. So far, President Barack Obama, Russian President Dmitry Medvedev and German Chancellor Angela Merkel are among those coming and no one has cancelled. Kaczynski's family insisted Friday they wanted the funeral to go forward as planned but there was no denying the ash cloud was moving south and east.

The air traffic agency Eurocontrol said almost two-thirds of Europe's flights were cancelled Friday, as air space remained largely closed in Britain and across large chunks of north and central Europe. "The skies are totally empty over northern Europe," said Brian Flynn, deputy head of Eurocontrol, adding "there will be some significant disruption of European air traffic tomorrow."

The agency said about 16,000 of Europe's usual 28,000 daily flights were cancelled Friday - twice as many as were cancelled a day earlier. U.S. airlines cancelled 280 of the more than 330 trans-Atlantic flights of a normal day, and about 60 flights between Asia and Europe were cancelled.

The International Air Transport Association said the volcano was costing the industry at least $200 million a day.

[...]

Aviation experts said it was among the worst disruptions Europe has ever seen. "We don't have many volcanoes in Europe," said David Learmount of Flight International, an aviation publication. "The wind was blowing in the wrong direction."

In Iceland, torrents of water carried away chunks of ice the size of small houses on Thursday as hot gases melted the glacier over the volcano. Sections of the country's main ring road were wiped out by the flash floods. More floods from melting waters are expected as long as the volcano keeps erupting - and in 1821, the same volcano managed to erupt for more than a year.

[...]

The ash cloud, drifting between 20,000 to 30,000 feet (6,000 to 9,000 metres) high and invisible from the ground, initially blocked the main air flight path between the U.S. east coast and Europe. On Friday, the cloud's trajectory was taking it over northern France and Austria and into eastern and central Russia at about 25 mph (40 kph).

So far, Icelandic volcano isn't likely to cause a cooler summer

Quote:
It may have succeeded at stranding Cory in the U.S., stranding Lisa in London and producing some beautiful sunsets (not to mention forcing John Cleese to pay for the world's most expensive taxi ride), but Mt. Eyjafjallajokull (say it 10x fast) isn't shaping up to drastically alter temperatures this year. At least, not so far, according to Alan Robock, professor of environmental sciences at Rutgers.

Robock told Climate Central's Andrew Freedman on Thursday that the output of Mt. Eyjafjallajokull hasn't put enough sulfur dioxide into the atmosphere to create the sort of "Two-thousand-and-froze-to-death" conditions some have feared.

Sulfur dioxide particles from volcanoes can temporarily cool the planet by reflecting solar radiation back out into space, effectively limiting the amount of warmth that reaches Earth's surface. Big eruptions—including some in Iceland—have led to short-term cooler temperatures in the past, and it's possible that, if the eruption lasts long enough, Mt. Eyjafjallajokull could as well. But there's another factor working in favor of a comfy summer, Robock said.

Quote:
The volcano's climate impacts may also be limited by its high latitude location, since the air circulation in the upper atmosphere in the high latitudes tends to be more efficient at getting rid of volcanic material, compared to lower latitudes where sulfur dioxide particles from volcanoes can linger for years.


Apparently it *will* help cause some bitchin' sunsets, though...

These people just get more and more out to lunch.

Andy's got some killer pics of Eyjafjallajökull posted, including "an intense shot of lightning inside the Eyjafjallajökull ash plume." Also, this rather ominous-sounding bit:

Quote:
"...previous Eyjafjallajökull eruptions have triggered eruptions of neighbouring Katla, one of the largest volcanoes in Iceland. Katla erupted every 40 to 80 years in the thousand years before the last eruption in 1918...The larger volcano, beneath the larger Mýrdalsjökull glacier, has a reputation for triggering huge jökulhlaup – the Icelandic term for the sudden release of meltwater from glaciers and ice sheets. Its last eruption generated a peak discharge of 1.6 million cubic metres per second within 4 to 5 hours and moved so much debris that Iceland's coastline was extended by 4 kilometres. A new Katla eruption would be unlikely to kill anyone, because the area is sparsely populated and eruptions are usually preceded by earthquakes that would give plenty of time to evacuate. It would cut the main road link in the south of the island, however...The three eruptions of Eyjafjallajökull in the last 1100 years – in 920, 1612 and 1821 – have all triggered larger Katla eruptions."


And for those wondering if all the grounded flights were necessary:

Quote:
Finnish fighter jets which flew through the ash cloud were said to have sustained damage:

Quote:
"Images taken inside one Hornet engine with a fibroscope camera indicated that the heat of the engine — around 1,000 degrees Celcius — had melted the ash inside the engine, blocking ventilation channels. 'Blockages of ventilation channels caused by melting ash lead engine components to overheat and material to weaken,' it said, adding this could fracture rotating engine parts. In the worst case, the weakening of component materials could cause 'parts to detach and the engine to be destroyed,' it said."

Volcano Pronunciation Guide

Quote:
Icelanders are apparently in stitches over the newscasters' attempts to pronounce the name of their global-economy destroying volcano.

Amazing video of the eruption and what it has done to the surrounding glacier.

It's fairly high res at full screen.

So it turns out with all these aircraft grounded 'coz of the Icelandic volcano, the overall air quality in that part of the world has *improved*... leading boing boing's Mark Frauenfelder to say, Bring back the blimps!

Quote:
The New York Times asked me and three other people the following question: "The Icelandic volcano that disrupted global air travel last week raised a concern: should we be thinking of alternative ways to move masses of people and goods?" My answer: bring back blimps (and dirigibles).

Quote:
Their large surface area and inherent buoyancy mean they can be run with solar-powered motors, making them eco-friendly. They can take off and land without a runway, which means they can load and unload passengers almost anywhere (no more airports!).

I'd be up for a world of dirigibles and trains.

British Airways leaves stranded passengers all over world, jacks up prices on tickets home

Quote:
After last week's volcanic eruption, British Airways passengers are stranded all over the world (I'm one of them). BA is rebooking people who hold paid for, cancelled ticket for return flights as late as May 10, but are selling tickets on flights leaving tomorrow for thousands of pounds to the wealthy who want to get home as quickly as possible. BA has had a year of terrible behavior and service, screwing its union by trying to unilaterally impose a contract on its workers without negotiation, but this takes the cake.

Quote:
We are trapped in Delhi with our children Iona (14 - missing GCSE exams), Sophia (13 - missing her part in the school play) and Dylan (seven - missing home).

BA have offered us a flight home on 10 May (we have been stranded since 16 April), but are still selling tickets on Delhi-London flights for thousands of pounds (which we cannot afford). The rich are allowed straight on to flights while the poor remain stranded. This is the real scandal of the volcano crisis.

We are among the lucky ones who BA have put up in a hotel but, with spirits low and tempers high, trouble is brewing - some people even had a "sit-down protest" in the hotel lobby on Wednesday. The Ramada in New Delhi is a very nice hotel, but our money has run out and we can't even afford the bottled water.

Volcanic Ash Cloud Turns Day into Night in Iceland

Quote:
Huge plumes of ash from the continuing volcanic eruption at Eyjafjallajokull glacier have all-but blotted out the sun in the region. Anything that stands still for more than five minutes begins to disappear under a choking layer of ash, and everyday objects take on an eerie 'dead' look in the dark, monochromatic environment. The thick column of smoke, steam and ash belching from the volcano shows no signs of abating, and scientists offer little comfort.


cool time-lapse clip @ link

Volcanoes Erupt In Ecuador And Guatamala

Quote:
Two volcanoes, Pacaya in Guatemala and Tungurahua in Ecuador, have both been erupting for several days. Guatemala, which has seen 10 deaths due to its volcano, has seen the worst devastation thus far, prompting President Alvaro Colom to declare a "state of calamity" and close La Aurora International Airport funtil at least this Wednesday.

One of those killed was a television reporting who was hit by projectile debris while covering the eruption.

Mother nature isn't allowing Guatemala to catch a break. Tropical Depression Agatha, which is packing quite a bit of punch, has just hit the country.

Meanwhile back in Iceland, experts are still concerned that Katla might still blow its top.


Video (and some cool stills) of Pacaya's eruption, as well as a CNN report @ link
