Images of the 2nd Round of Eruption at Eyjafjallajökull Volcano
Eyjafjallajökull Volcano produced its second major ash plume of 2010 on May 7. The Multi-angle Imaging SpectroRadiometer (MISR) aboard NASA’s Terra satellite collected data on ash height when it passed just east of the Eyjafjallajökull Volcano mid-morning on May 7.
MISR has nine different cameras, each viewing the scene below from a difference angle nearly simultaneously. By combining all these images using a hyper-stereo technique, scientists can calculate the height of the ash plume.
The above image is a natural-color, nadir (downwards-looking) view of the scene. The top image is the stereo-derived plume height. Each pixel in the image shows an area 1.1 kilometers (0.68 miles) wide. The vertical accuracy is about 0.5km.
Much of the plume resides between 4 and 6 kilometers above the ocean surface (orange and red color in the right image), but the ash descends to near 3 kilometers yellow-green) far downwind. Images and caption: NASA/MISR [edited for brevity.]
Status Report – 15 May 2010 (3:55UTC)
The Icelandic Met Office (IMO) reported plume reaching a height of about 7 km (24,000 ft) drifting in a southwesterly direction. Ashfall was detected in the capital Reykjavík.
At least 50 lightning strikes were recorded during the previous 24 hours. No major changes in the activity were reported. There’s no sign the eruption could end anytime soon.

LATEST NEWS FROM ICELAND:
Volcanic ash from Eyjafjallajokull eruption has forced the authorities to shut down the intentional airport at Reykjavík, the country’s main airport, authorities say.
UK Airspace
Parts of the UK’s airspace may close on Sunday as volcanic ash clouds continue to drift south of Iceland, the UK Department for Transport said, BBC reported.
Last week, about a dozen airports in southern Europe were forced to close and many flights were re-routed to avoid the risk from the Icelandic ash clouds.
