amount of fine, dark ash
detected on a white plate in Hvolsvöllur 06:00 this morning.
Lightning: No detections today over the eruption site.
Noises: No reports
Meltwater: Similar to yesterday, daily fluctuations in discharge and temparature.
Conditions at eruption site: The eruption is still in an explosive phase. The tephra and
spatter cone continues to build up and is now reaching near

especially in
the coastal districts. The first half of July was wet but the later part of the month brought fine,
warm summer weather to the southern part. August was close to average in the South and
West, but wet and cold in the North and East. Akureyri recorded the lowest number of
sunshine hours in August since 1969.
September was cold, generally the coldest September since 1982. It was very

images.
Heading: West and possibly southwest from the eruption site, but probably
remaining close to Eyjafjallajökull due to light winds.
Colour: Cloud-cover obscured direct observations.
Tephra fallout: Light, fine-grained ash-fall reported in the morning during rain at
Ásólfsskáli, located 10.5 km south-west of the eruption site. Similar
conditions also reported from a farm 12

Heading: South and south-west from the eruption site, but probably remaining close
to Eyjafjallajökull due to light winds.
Colour: White (steam) clouds at higher elevation; dark grey (ash) clouds seen
intermittently at lower elevation (see above).
Tephra fallout: Dark, fine-grained ash-fall reported over a 10 km region south of
Eyjafjallajökull between Núpur and Skógar.

than 10 micron (aerosols). This is a considerable decrease of
fine particles compared to ash from April 15th (25% aerosols) sampled
at a similar distance. The grain size analysis was carried out by
Nýsköpunarmiðstöð Íslands.
Overall assessment: Explosive activity seems to have decreased since yesterday. The
ash plume does not rise as high into the air and is lighter in colour.
Steam rises from

It is possible that some fine dust is mixed into the plume at this level and then lofted by
the rising plume into the eruption cloud. However, the white color of the plume and the cloud that it feeds into, and the lack of fallout implies that
this only occurs at a limited rate, if at all. (Photo: Pálmi Erlendsson)
The seventh photo shows that the plume rises evenly from although an

conditions. The summer was warm and considered fine in the North and East but in the south it was very wet and dull. The autumn was fine, November extraordinarily warm, but the year ended with an unruly and rather cold December.
Temperature
The year was very warm, +1.4 to +2.6°C above the 1961 to 1990 average. The lowest departure from normal was at Stórhöfði off the south coast, but the highest
