Satellites Keep Aircraft Away From Volcanic Cloud

coondoggie writes "A range of satellites from a host of different nations are pumping out images and data on the Icelandic volcano currently wreaking havoc on commercial airline traffic and aviation in general. The European Space Agency today noted four major satellites that are monitoring the volcano that erupted this week under Iceland's Eyjafjallajoekull glacier. They include NASA's Aqua and Aura as well as the European Space Agency's Envisat and MetOp spacecraft. Other satellites such as NASA's Terra and NOAA's GOES satellite also provide images." Updated 20100416 01:17 GMT by timothy: Apropos that, 2Y9D57 writes with this "Image of the Icelandic volcano, Eyjafjallajökull, after it began erupting on 15 April. Acquired by the German TerraSAR-X synthetic aperture radar satellite from a height of about 500 kilometers / 300 miles."

      When this volcano blows a major Katla eruption follows soon after. Katla is about 10 miles East.

      This one shuts down half the air travel in western Europe for a few days. Katla shuts down summer. The farmers are not worried about this volcano:

      "I am not afraid of this eruption but I fear Katla. It might not happen immediately but it will happen. Then we will be talking about much more power," Agnarsson said.

      It has to do with the type of plate tectonics here. The plates are pulling apart, yielding a very deep rift that releases very hot magma from very far down in the mantle, which is saturated with CO2 and when released goes very high, far, thick and long. Naturally this will melt a great deal of Iceland glacier very quickly, impacting the currents in the Atlantic.

Naturally this will melt a great deal of Iceland glacier very quickly, impacting the currents in the Atlantic."

      This is true for all of the volcanoes in Iceland. They are related to the rifting that occurs along the mid-Atlantic Ridge, where the North American plate is stretching away from the Eurasian Plate. The magma comes up the cracks and eventually erupts onto the surface. CO2 has little or nothing to do with melting the glaciers. The heat of the lava at the vent does, and the contact with the water produces much of the explosiveness that eventually produces ash and lofts it into the atmosphere. The climatic effects are mainly from a combination of the ash particles and aerosols such as sulphur dioxide, and they are mostly cooling effects due to obscuring the Sun, however, Eyjafjallajokull is not a big enough eruption -- so far -- to have a significant climatic effect. Katla, by contrast, is a much larger volcanic center and has historically had much bigger eruptions, hence the worry if that one blows too. The effect on Atlantic ocean water is negligible except around Iceland itself.

      There are plenty of the more technical details at the Nordic Volcanological Center site, including a link to this paper [PDF] that has ample detail about these two volcanoes and their historical and more modern behaviour. It isn't cause for optimism. The key phrase from the introduction is that eruptions at Katla have been up to 2km3 in volume, whereas those at Eyjafjallajokull "have been negligible in historic times and range in the 0.1km3 scale. This is a "small" eruption. Really. Even with that "negligible" volume, the most recent eruption lasted from 1821 to 1823, and was with Katla erupting simultaneously. These eruptions have sometimes A) lasted for many months or years, and B) been much, much larger if Katla erupts too. Not to mention the local effects such as even bigger jokulhlaups than have been triggered so far, and for some eruptions (e.g., Laki in the 1700s), release of toxic gasses such as HF too. Sometimes the eruptions are no big deal, and they wane and stop over a few weeks. Sometimes they are nasty and prolonged. It isn't clear what this one will do, but if there are signs that Katla is going to join in ... be prepared for something much more awful.

      "WHEN" it blows, not "IF".
      Another eruption of Katla is a racing certainty ; when it happens is much more open to question. It seems from historical records that there's a high probability that it'll go in the next few months to years. Which will make life interesting.

As sea levels rise, increased weight is applied to continental shelves and tectonic plates and weight is decreased where the ice was. I wonder if this could cause the plates to shift.

Some scientists have made a similar assertion to icecap melting leading to increased vulcanism;

      They said there was no sign that the current eruption from below the Eyjafjallajokull glacier that has paralysed flights over northern Europe was linked to global warming. The glacier is too small and light to affect local geology. Ice cap thaw may awaken Icelandic volcanoes
