Assessment - 13 May 2010 19:45
The eruption plume is gray and heading southeast. The height is mainly
6 km (20,000 ft) but has reached up to ~ 9 km (30,000 ft). Wind is calm
over the eruption site and unstable air south of it, which does affect
the height of the ash cloud.
Ashfall has been reported since 6 o’clock this morning from various
farms in the vicinity; the ash is somewhat finer today than yesterday.
Twenty lightnings were recorded on the ATDnet since last night (UK Met
Office). Only the upper part of the ash cloud and the lower part of
Eyjafjallajökull could be seen during air surveillance, see photos
below; ordinary clouds obscured the view.
No major changes are seen in the activity, although the ash plume has
increased in hight since yesterday. Presently there are no indications
that the eruption is about to end. The above is based on a [9]status
report issued collectively by the Icelandic Meteorological Office and
the Institute of Earth Sciences at 16:00.
