Good morning all to you! She is at the poro/voda good to watch, some cloudy. The meltwater is slowing down. But it is still very early there 04.00.
For we now we have a beautifull day
Official report 5 may:
Eruption in Eyjafjallajökull
Status Report: 18:00 GMT, 05 May 2010
Icelandic Meteorological Office and Institute of Earth Sciences, University
of Iceland
Compiled by: Sigurlaug Hjaltadóttir, Björn Oddsson, Matthew J Roberts, Sigrún
Hreinsdóttir, Freysteinn Sigmundsson.
Based on: IMO seismic monitoring; IES-IMO GPS monitoring; IMO hydrological data;
IMO weather radar measurements, MODIS satellite image; reports from
people via phone and the IMO web site, information from the Icelandic Coast
Guard flight yesterday.
Eruption plume:
Height (a.s.l.): Plume at 5.5-6.5 km height according to IMO's weather radar; reached
up to 7.2 km 40 SA of eruption site at 17:45 and 8 km height just SE
of eruption site at 16:55. Information from ISAVIA: 18-20,000 ft at
14:50 GMT. Information from a Boeing 757 plane at 17:50: black
plume in 21,000 ft (6.5 km).
Heading: East-south-east over land and then towards southeast according
to a MODIS image at 12:45.
Colour: Black (see info. above). Bluish fog seen from Álftaver (65 km
distance).
Tephra fallout: Sólheimaheiði, Hjörleifshöfði and Álftaver (up to 70 km distance).
Lightning: No detections today over the eruption site.
Noises: Loud noises at farms south of the volcano troubled people during last
night. Reports from people hearing loud noises in up to 200 km
distance west and northwest.
Meltwater: Due to mild weather and snowmelt, increase in discharge was noticed
in Markarfljót peaking at midnight. Discharge from Gígjökull seems to
be decreasing and oscillations in water temperature at the old
Markarfljóts bridge relate to air temperature. Pulses of meltwater from
Gígjökull are unnoticeable. At midnight electrical conductivity began
to rise in Jökulsá á Sólheimasandi. Since then the conductivity has
raised from 170 μS/cm up to 590 μS/cm (hr:15:00). Possible reason for
this is volcanic ash from the eruption getting in to the meltwater from
Sólheimajökull. Samples of the water have been collected for
analysis.
Conditions at eruption site: The eruption sight was not visible today. From the flight of
the Icelandic Coast Guard (ICG) 04.05.2010: The crater continues
build up in the northern most ice cauldron. Lava flows to the north and
spreads at 500 m a.s.l. The lava tongue is about 200 m wide and lava
channels that join at the tongue are about 30-60 m wide. The lava
channles gets wider every day.
Seismic tremor: Similar to yesterday.
Earthquakes: Continued seismicity, between 20 and 30 earthquakes have been
located beneath the ice cap since 3 May, first deep (18-23 km) but
GPS deformation: Significant changes in horizontal movement at GPS stations around
Eyjafjallajökull have been observed in the last 48 hours. Renewed
northward displacement is seen at stations BAS2 and STE2, located
just north of the ice cap. To the south, westward movement is apparent
at THEY, while station FIM2 - located further east - shows eastward
movement.
Other remarks: Weather conditions probably cause the loud noises to be heard over
long distances.
Overall assessment: Increased seismicity suggests that new material is intruding from
deep below Eyjafjallajökull and latest GPS-observations suggest inflation. So far, GPSsignals
are not large. There are no signs that the eruption is about to end.
