Height (a.s.l.): 5 - 6 km / 17,000 ft - 20,000 ft.
Tephra fallout: No reports, but clearly seen on video cameras.
Lightning: Nine lightning were recorded on the ATDnet.
Noises: No reports.
Low water discharge at Gígjökull.
Conditions at eruption site:
Observations from air and web cameras show similar activity to yesterday. In the afternoon there was an increase in explosive activity, giving darker
and slightly higher plume.
Slight increase in the lower frequency bands.
Sixteen earthquakes were located since yesterday, mostly at depths of 18 – 20 km and magnitude less than Ml 2.
Small displacements towards the center of Eyjafjallajökull volcano but irregular oscillations in the vertical component of a station closest to the
No major changes are seen in the activity, but small variation can still be expected. The ash plume increased slightly in the afternoon. Presently
there are no indications that the eruption is about to end.

Iceland Volcano Update
1218 BST on Tuesday, 11 May 2010
Latest information received from the Icelandic Meteorological Office indicates that the explosive activity from the Eyjafjallajökull volcano is
continuing, with the ash plume reaching heights of up to around 18,000 ft. The Icelandic Met Office state that there are no signs that the eruption is
about to end, with the volcanic eruption remaining dynamic.
Winds are expected to blow from a mainly north or north easterly direction over the next few days, with most of the ash cloud likely to stay over the
Atlantic Ocean and close to western parts of the British Isles. As a result NATS continues to advise aircraft about airspace restrictions affecting
transatlantic flights, allowing them to cross the Atlantic safely. Recent weather patterns mean that the ash cloud has drifted across some parts of
central and southern Europe, leading to disruption.
As the volcanic activity changes, the Met Office will continue to provide frequently updated information to NATS and CAA about the dispersion of the
volcanic ash, in line with the new engine criteria set by the CAA and the aviation industry.
Any decisions on airspace closures are the responsibility of CAA and further information on the impacts of this increased activity should be sought
