20 to 18 k deep.... guess chamber is filling up... ore water leaks in it??

The last three 2.0+'s (all in succession) were around the 1km deep mark - v. shallow..

We're getting glimpses on the Voda cams now.

That's one big mother of a water outlet now!!
Reminds me of when we were in Austria and walked through a tunnel through a glacier!

Too foggy for the moment so can't see much on any cam.

The tremors on the chart shows a decrease in activity while we are having an increase in small earthquakes. Looks strange to me, someone has an explanation?

Whoa - massive changes on glacier - looks like it's collapsed inwards?

Where you looking at Moorf?

I am looking at Poro now that it has cleared up a bit.
Looks like the "main" vent quite active and seemingly quite explosive.

View even better now... on Voda

Two dark "pillars" now in view at bottom-most viewable area of glacier - rock or ice, not sure - but huge gaping hole between them!

Goodmorning (Vulcans) to you all. Here we go again on a beautifull day!

Official report from 3 may:

Eruption in Eyjafjallajökull - Status Report: 16:00 GMT, 03 May 2010
Icelandic Meteorological Office and Institute of Earth Sciences, University of Iceland

Compiled by: Sigurlaug Hjaltadóttir, Freysteinn Sigmundsson, Björn Oddsson, Sigrún Hreinsdóttir, Þórdís Högnadóttir.

Based on: IMO seismic monitoring; IES-IMO GPS monitoring; IMO hydrological data; web cameras of the eruption site from Vodafone; IMO weather radar measurements, MODIS satellit image; information from scientists at Gígjökull, information from the Icelandic Coast Guard flight.

Eruption plume:
Height (a.s.l.): Largest plumes observed at 5-5,5 km height (17-18,000 ft) estimated from the Icelandic Coast Guard (ICG) flight at 14:30. The plume has also been observed on IMO's weather radar at 4.0-5.2 km height between 13:00 and 15:00 GMT. The plume rises higher after large explosions.
Heading: East-south-east to south-east from the eruption site. Plume track clearly visible at least 200 km from the eruption site and probably another 200 further to the SE on MODIS (11:20 GMT) satellite imagery.
Colour: Observation from ICG-flight: Dark grey (ash) clouds observed over the eruptive site. White (steam) plumes rising from Gígjökull otulet glacier, north of the eruption site (similar as yesterday).
Tephra fallout: Moderate ash-fall reported in Álftaver, 65-70 km east-south-east of Eyjafjallajökull (07:00-10:00 GMT. An ash cloud also observed over village of Vík (10:00 GMT), 40 km south-east of Eyjafjallajökull.
Lightning: No detections today over the eruption site (16:00 GMT).
Noises: Scientists working at Gígjökull regularly hear explosions and booming sounds and feel the ground vibrate. The vibrations are not felt in 3-4 km distance.

Additional note: The scientists at Gígjökull experienced discomfort due to gas.

Meltwater: Today water temperature at the Markarfljot bridge was measured 11°C but about 3°C in a 2 km distance from Gígjökull. Water is flowing on both sides of the glacier and pulses of meltwater flow down the channels every 10 minutes or so (according to scientists at Gígjökull). Water level gauge at Gígjökull also records the pulses. Temperature measurements at Markarfljot bridge show a pulse of water temperature up to 17°C at 06:00 GMT this morning and another smaller pulse reaching about 15°C between 08:00 and 09:00. Water temperature has now dropped down below 4°C.

Conditions at eruption site: The eruption site was seen on a vido camera around noon (13:00 GMT). Dark ash clouds propagating eastwards. The lava is probably still propagating down Gígjökull producing more meltwater and steam.

Seismic tremor: Tremor levels intensified last night (2 May) and have remained high since. This intensification is seen in the frequency range 0,5-2 Hz but not above 2Hx (2-4 Hz).

Earthquakes: A few earthquakes occurred early this morning. They seem to be located at about 18 km depth just south of the eruption site.

GPS deformation: Horizontal displacement towards the center of Eyjafjallajökull volcano. Vertical displacement at stations closest to the eruption site had indicated increased subsidence rate in the last few days but now the deformation is similar as before 29. April.

Other remarks: No measurable geophysical changes within the Katla volcano.

Overall assessment: The overall activity has not changed much since yeasterday (from the last report). Presently there are no indications that the eruption is about to end.

Poro is clear for now, dark clouds? The Dutch news say that ther is still 60 tons of magma per second that she produces? The pressure must be enormus. The water off the melting glacier floods on 2 site's. Is ther a webcam for the other site to watch?

After being away for most of the day yesterday and not being able to see much lastnite, i cant get over how much its changed. We definately seem to have had the 'collapse' that everyone expected and its looking like theres more to come.

Check out these two screenshots and you'll see just how drastically the geography has changed on the glacier... amazing - it has collapsed/melted and morphed

Great video of close up of what we were watching on Poro and Voda cams... really shows the scale. In Icelandic, but video speaks for itself
