Iceland’s Volcanoes Could Potentially Cause Collapse of Europe
Eyjafjallajökull Volcanic Ash closes Airspace over Ireland and Scotland Once Again
Airspace over Northern Ireland and Scotland will be closed from 07:00 to 13:00GMT (UTC) on Wednesday due to a new cloud of volcanic ash drifting from Eyjafjallajökull Glacier volcano in Iceland, the UK Civil Aviation Authority said.
The ash cloud is expected to move further south, possibly forcing the closure of airspace in the NW England and north Wales today.
“The situation is very dynamic, so passengers expecting to travel from the impacted airports should contact their airlines to check whether their flight is operating,” CAA website said.

These images are monitoring for the presence of volcanic ash emission in the vicinity of Iceland using infrared data from the Meteosat Second Generation (MSG) satellite. Because cloud particles and volcanic ash particles interact with the infrared radiation in different ways, data at several different wavelengths can be combined to identify the main ash plume, which, when present, would be shown as yellow and orange colours in the images. Note that it is only the thicker parts of the plume that are able to be detected by this method. In addition, the ash plume is often masked by overlying high cloud.

A Webcam Image of Eyjafjallajökull Eruption saved by Icelandic Review yesterday. The webcams seemed to be out of action today.
One function of webcams is to prevent unnecessary traffic to the site of volcano, which could also be extremely hazardous.
Icelandic Met Office said:
Plume was observed at 5.8-6 km height (19-20,000 ft) estimated from the Icelandic Coast Guard (ICG) flight at 10:40 and 15:30 GMT. It is heading east-south-east to south-east from the eruption site. Plume track clearly visible up to 300-400 km distance from the eruption site on a NOAA satellite image at 13:13 GMT.
On lava flow they reported:
Lava is still flowing northwards, forming a lava fall down the steep hill under Gígjökull, about 4 km north of the crater. Blue gas is seen rising from the lava and white steam plumes are seen somewhat lower and mark the front of the lava stream. The size of the eruptive crater is 280 x 190 m. Lava splashes are thrown at least a few hundred meters into the air.
Status Report: 14:00UTC, 04 May 2010 – IMO and Earth Science Island:
Explosive activity and ash production is strong and has increased since yesterday. Dark ash plume rises above the crater. Lava is still flowing northwards, forming a lava fall down the steep hill under Gígjökull, about 4 km north of the crater. Blue gas is seen rising from the lava and white steam plumes are seen somewhat lower and mark the front of the lava stream. Radar images from ICG-flight today show tunnels in Gígjökull increasing in size and continuing the build up of the cone at the crater. The size of the eruptive crater is 280m x 190m. Lava splashes are thrown at least a few hundred meters into the air.
