Ground inclination plots for Grimsvotn, not showing any deflation yet meaning whatever is yet to be ejected is still 'prepping' the mountain up. Until deflation occurs on the plots the eruption continues.

Indications and preliminary reports suggest that Hamarinn has possibly erupted, located on the western edge of the Vatnajokull shelf. This would explain the increase in sferics (lightning) and output seen on radar.

Update folks,

Just found this on Yahoo....

uk.news.yahoo.com... 0115232.html


Britain's airspace could be forced to shut down completely this week after another volcano in Iceland erupted, spewing tons of ash into the air


So much for this one not having the potential to wreck as much air traffic chaos, as last years eruption.

Same time next year for Katla eh ?

great thread

if this other volcano has erupted as well , how much worse will the situation be?
would it trigger any of the others in the area?
will it mean that flooding is now more likely?
sorry for the questions...just interested, have a strange fascination with all natural disasters but am not clever enough to decipher all the scientific stuff

Things somewhat levelling off now gradually, with the plume becoming less evident by the hour on the Icelandic radar brunnur.vedur.is...

This ties in correspondence with the earthquakes trend I was mentioning earlier this morning where it seems Grimsvotn calms down before flaring up again periodically over a 6 hour span throughout the day, wether this is another continued trend is yet to be seen but the estimates are showing so. en.vedur.is...

Given that tilt registers haven't showed any deflation in the mountain, any subsidence of the activity is purely pre-speculative and can be indicative of a number of factors from dome formation (blockage), magma migration or diffirential properties extrusion as previously seen during the Hekla eruption where a number of eruptive events from strombolian to Plinian took place.

Just to say if Hamarinn or Barobunga were fed by magma migration from Grimsvotn the saving grace is that we'd at least be forewarned from shallow fracture quakes breaking beneath the crust and eventually registering surface as it hits the ice. This ice-cap of Vatnajokull along the western region has solidified over the 2 calderas for thousands of years, no historical record goes back to show the nature of either Central Calderas so what kind of eruptive event were likely to see is mainly based on the other Central Volcanic eruptions that we know and are witnessing now.
As with any volcano under this amount of ice, if such a eruption was to happen you can be sure massive floodings of unprecedent porportions will take place. As will the initial Phreateomagmatic event.

This is a google translate from vedur.is... i tried cleaning it up a little., and as u wil notice it´s upside down so , the erliest report at the top

eruption Grímsvötn
Monitor the situation

23. May 2011 - kl.18: 45

Common base and service IES report was released at. 17:00.

The height of the smoke has been around for 5 to 9 miles past times than it should be remembered that the very sharp winds on site which may affect the hill. Side Mocha Circle is to the south. At 8 km and higher east winds and then goes that part of smoke in the west.

Much volcanic ash was from Vik in Myrdal and east Öræfajökull. Most volcanic ash has been in the vicinity of Kirkjubaejarklaustur. Ash dust has been observed in many students from the country's northwest side. Has declined since the volcano yesterday. No lava was a crater in the morning.
23. May 2011 - at. 16:45

IMO, recently received a loan from lidar National Centre for atmospherics Science (NCAS) in the UK. Lidar instrument is based on a laser beam shooting into the air and measure its reflectance. The device had been installed under Eyjafjoll to measure fokösku but was transferred yesterday to the Department to monitor the ashes over the pitch. On at. 20 last night took the device to show an increasing amount of ash in the air and remained there through the night.

IMO located on Miðnesheiði, near airport. Starring veðursjá variant is to monitor rainfall, which measures the reflection from water droplets in the atmosphere. It has been shown that veðursjáin can also be used well to monitor eruption smoke but she sees her reflection in the various arguments eruption partical smoke.

The glacier eruption revealed that Veðursjáin was useful tools, but the distance to eruption center (which was 160 km) reduced somewhat from the quality of the data. Because of this it was decided to purchase a transportable X-band tic veðursjá and get another loan from italian civil protection during the purchase. Mobile veðursjáin is now located near Kirkjubæjarklaustur or in the 80km distance from the eruption site Grímsvötn. Employees We monitor the development of the volcanic eruption with two veðursjám.

23. May 2011 - 14:45

The eruption tension was rumbling s.l. night and still is. Longest tension have remained roughly 40 minutes. earthquake activity has been low. The smoke has been in the 8-10 km altitude so far this day. GPS devices that show the movement suggests that active magma in the magma chamber under Grímsfjall.

East and northeast directions states across the country today and ash has been to the southwest and south in the lower layers. Widely expected to ash fall, although perhaps most notably the northwest corner of the country. Wind will go north later, first in the lower laws, but in the upper layers in the evening and night. Map showing the distribution of ash is under construction and will be published later today.

22. May 2011

The eruption is much stronger than it was in 2004 Grímsvötn and somewhat more powerful than the eruption of the eruption. Today the smoke has been for about 10 km and again at 11 km. Veðursjá new mobile service that was performed in the vicinity of Vatnajökull shows this trend. Confirming that erupted in Grímsvötn is in their box near the place which erupted in 2004. Last ran from 31st Grímsvötn October 2010, a little water has gathered together and thin ice on the carton. When Grímsvötn erupted in 1998 and 2004 there was a Glacier Burst shortly after the eruption began. Is not expected to corresponding conditions are down now and do not expect the ice circuit.

Meteorological Station joint report and IES was released at 22.05.2011. 17. Overall, has declined slightly since the eruption was at its peak last night when the magma flow may have reached over 10 thousand tons per second. Fluid flow afternoon is considered in the order of 2-5 tonnes per second. No lava was a crater in the morning.

21. May 2011

At about 17:30 today, began to measure increased restlessness with sources in or near Grímsvötn and eruption is now started. From the plane was on route from Akureyri to Reykjavik and from 18 to 20,000 feet saw mocha than it does now from Egilsstadir to Selfoss.rticle

There´s a feature now on www.vedur.is... that shows you the predicted flow for the ashfall.

"Hádegi" means noon
"miðnætti" means midnight

And the gray dot means area´s there have been reported ashfall on areas

Check out this amazing video shot from a helicopter, its the latest video of the eruption and shows the lightning being created by the ash cloud all very apocalyptic.

I am in Dublin in Ireland

This afternoon the car windows were dirty, then we had torrential rain and high winds which cleaned the windscreen,while I was driving, 20 minutes laters when I had finished the school run my (black) car was completely grey, to me it looks like we have had more ash cloud fall this time already

It is still howling wind and freezing rain, tomorrow I will take a before and after pic, we have been told to expect the full ashcloud in the afternoon, last time it was an inch thick on the garden furniture so I will clean the table then take a pic when the ash is very visible

The official report from 23 may:

Grímsvötn volcano
Status Report: 17:00 GMT, 23 May 2011
Icelandic Meteorological Office and Institute of Earth Sciences, University of Iceland
Compiled by: Gunnar B. Guðmundsson, Níels Óskarsson, Einar M. Einarsson, Árni
Sigurðsson, Bergthóra S. Thorbjarnardóttir, Matthew J. Roberts and
Sigrún Hreinsdóttir.
Based on: IMO seismic monitoring; IES-IMO GPS monitoring; IMO
hydrological data; weather radar; ashfall reports; UK Met Office
ATDnet; MODIS satellite images.
Eruption plume:
Height (a.s.l.): The ash plume reached heights of 8 to 10 km last night and this
morning. In the last hours, the plume has reached heights of 5 to 9 km,
but northerly winds have been very strong which can effect the height.
Heading: Most of the ash cloud heads to the south. At altitudes of 8 km and
higher, part of the plume heads to the west.
Colour: Brown- or grayish and sometimes black close to the eruption site.
Tephra fallout: The amount of fallout is great from Vík in the west to the east of
Öræfajökull. The amount of ash fall is the greatest close to the village
Kirkjubæjarklaustur. Ash has been detected in several areas throughout
the country, except in the northwest.
A sample from Kirkjubæjarklaustur has been analyzed, which was
taken around 1h on 22 May. The grains are glassy with micro crystals
of plagioclase. Samples well sorted.
Whole rock analysis: Basalt, with 50-51 Wt% SiO2
Leachate results: 5-10 mg/kg of waterdissolvable flour
Grain size distribution: about 10% of the volume of the analyzed
samples is finer than 10 micrometers
Lightning: From 17-18h yesterday, about 300 lightning strikes were detected but
much less thereafter. The strikes were most frequent south of
Grímsvötn.
Noise: No noise from the volcano has been reported.
Meltwater: No changes in water level have been recorded in the rivers Gígja and
Núpsvötn. Since the eruption is practically at the same site inside the
Grímsvötn caldera as the last eruption, ice-melt is not expected to be
great and therefore swelling of rivers in the next few days is not
expected.
Conditions at eruption site: The eruption site is in the southwest corner of the
Grímsvötn caldera, in the same site as the 2004 eruption. The basaltic
magma is fragmented into tephra in violent magma-water interaction.
Very powerful explosions occur at the eruption site.
Seismic tremor: Seismic tremor at the Grímsfjall station was fairly stable last night.
After midnight andtoday, the tremor levels have been fluctuating and
decreasing slightly.
Earthquakes: No earthquakes have been recorded in the volcano since yesterday
afternoon.
GPS deformation: Rapid deformation was detected at the CGPS station Grimsvotn
(GFUM) in the first hours of the eruption. GFUM is located 5 km east
of the eruption site. In the first four hours the site moved ~ 20 cm in
the north direction, 15 cm towards west and subsided 10 cm. The
deformation rate has since slowed down, with the total displacement in
the first two days of the eruption about 50 cm to the northwest, with 25
cm subsidence. These displacements are ~60% larger than comparable
measurements made after the 1998 and 2004 eruptions of Grímsvötn.
Overall assessment: The eruption has abated slightly since yesterday. No effusion of lava has
been observed.

Here is the official report from 24 may:

Grímsvötn volcano
Status Report: 16:00 GMT, 24 May 2011
Icelandic Meteorological Office and Institute of Earth Sciences, University of Iceland
Compiled by: Gunnar B. Guðmundsson and Freysteinn Sigmundsson with input
from Elín Björk Jónasdóttir, Árni Sigurðsson, Bergthóra S.
Thorbjarnardóttir, Þórður Arason, Matthew J. Roberts, Gunnar
Sigurðsson, Björn Oddsson, Magnús Tumi Guðmundsson, Ingibjörg
Jónsdóttir and Sigrún Hreinsdóttir.
Based on: IMO seismic monitoring; IES-IMO GPS monitoring; IMO
hydrological data; weather radar; ashfall reports; UK Met Office
ATDnet; MODIS and NOAA satellite images
Eruption plume:
Height (a.s.l.): The ash plume was not visible on radar for most of the night and early
this morning due to weather conditions at the eruption site and around
it. The estimated height is below 5 km since clouds over the glacier
were at 5-7 km and the plume did not reach above the cloud deck.
The ash plume reached 8 km briefly at 14 UTC today, but decreased
shortly there after. According to pilot reports the plume is visible at
around 10 thousand feet, mostly light gray or brown in color, but
pulsating to 15 thousand feet, and becoming darker in the process.
Based on plume height, the estimated magma discharge rate equals 10-
70 tonnes/s of ash. A large part of Vatnajökull is covered by clouds
and the eruption plume is not well defined in satellite images. South of
Iceland images show visible ash extending over 800 km from the
eruption site towards the south and southeast.
Heading: A large part of the ash heads to the south.
Colour: Mostly light gray.
Tephra fallout: The axis of the main tephra sector has a direction S - SSW from
Grímsvötn. Ash clouds is mainly confined between Lomagnupur and
Myrdalsjökull. It is not very thick and it is mixed with blowing ash. In
Kirkjubaejarklaustur the ashfall has decreased compared to yesterday.
The visibility this morning was around 200 m but around noon only
100 m and the sky became dark.
Lightning: No lighning strikes have been detected since yesterday afternoon.
Noise: No noise from the volcano has been reported.
Meltwater: There is no sign of flooding in the rivers Gígjukvísl or Núpsvötn,
which drain from the Skeiðarárjökull glacier. As the eruption is
occurring at the same location as the 2004 eruption, little ice is
available for melting. A large outburst flood (jökulhlaup) is unlikely,
assuming that the eruption remains in the same location. The electrical
conductivity of Núpsvötn has continued to increase; this is due to ashfall
on the western side of Skeiðarárjökull. Conductivity levels in
Gígjukvísl remain unchanged.
Conditions at eruption site: The eruption site is in the southwest corner of the
Grímsvötn caldera. Weather conditions have prevented overview
flights since yesterday. The eruption has not yet been visited on
ground.
Seismic tremor: Seismic tremor at the Grímsfjall station has been fairly stable since
yesterday afternoon but some fluctuations are observed.
Earthquakes: No earthquakes were recorded in the volcano today. Three earthquakes
or possible icequakes occurred about 12-20 km south of the volcano
yesterday evening.
GPS deformation: The GPS-station at Mt. Grimsfjall showed insignificant displacements
from 00:00 – 24:00 yesterday.
Overall assessment: Based on the development of plume height, ash fall in inhabited areas
in Iceland, number of lightning strikes, seismic tremor and ground
deformation, it is inferred that the strength of the eruption continues to
decline, with present explosive activity only a small fraction of its
initial values.

Seismographs indicate fluid movement now making its way through the vent of Grimsvotn


I understand your credentials but why not put up some documentation to SHOW what you are talking about so people can learn rather than making statements that are meaningless to those not in the know. In addition if you are quoting seismographs, which ones? There are many around the area. Do they all show the same? Are you looking at the tremor plots or actual seismograms. Would a seismogram show this, or have you deduced this from tremor plots? Your sources please.

A picture.....and all that.

I have cleaned the black glass table and checked it to the point of it becoming an obsession and........
No ash, not even a little bit of ash so it looks like the very high winds we are having has diverted it somewhere else
