Iceland's Eyjafjallajokull Volcano - Discussion Thread

[coldfingers]

There were several bright white spots near the top and a broad dark smokeplume above them on the axis cam. On the left of that was a plume of white steam visible.

Many thanks for that nightfire. For some reason it wouldn't load for me. I did notice the rather big heat signature near the top when I got it in the end. So it looks like the lava is still flowing, even if it might be at a lower rate, but it is obviously still losing the battle with the ice. Such a shame as I so much want it to break through and flow into the valley. However it looks like she is too much of a lady to do more than glow at the moment.

Can anybody see how red the sun is this evening? It looks evil from where I am, unfortunately I don't have a camera to photograph the sunset.

[LadyPakal]

The sky here (the sun has a long way to go before it sets) has an orangy haze to it. We've had a lot of dust fallout since yesterday.

Not my pics but the dust looks like this under the microscope.

I also have pollen grains & some brownish angular stuff - looks a bit brown mica (Biotite) like - in sheets.

Edited, the colour of the sky is deepening - I think it will be a good one tonight!

Same here in the Lowlands of Holland.

Just have a look at the Poro axis cam. Isn't there an awfull lot of ash between the rocks?

There's a definite haze giving the sky its colour tonight. You can see it has streaks & 'edges' for want of a better word.

Yes, for the last couple of days the ash plume has been directly over the webcams on Thoro - hence the crap viewing.

You remeber the lava hotspot which the heatsensor was extremely fond of? The white spots I mentioned where slightly higher and to the left of that. More like in a straight line above the split rock and with the dark plume above it.IR cam now shows the old three lavaspots again so I guess the new spots were all steamplumes.

A question for you all when you finally wake up. :lol:

Just looked at the tremor charts and wondered if anyone knows what area the hvo chart covers?

My reason for asking in I am wondering at the difference in tremor activity on that one compared to the rest. It is rising steeply whereas the rest seem to be staying similar to the recent activity.

Back to bed to see if I can get back to sleep.:ph34r: The only time in my life insomnia has had any advantage.

If you look close enough you can see the locations here http://www.acsys.it/volume/php/home.php?&id=8

Many thanks PIT. And thankfully I now know how to zoom in easilly. Eyes aren't what they were. :ph34r:

That is a really interesting map for the seismicity over the years too. Shows no need for people to worry about the odd quake under Katla, there have been more than plenty over the years.

Webcam viewing is atrocious again, even the Hvollsvelli cam looks like it is getting a share of ashfall in the area. Poor farmers! I was looking at a photo last night that someone posted (think it might have been the Eruptions blog) and I was amazed at the amount of ash accumulating in some areas.

[The PIT]

Well the ash cloud is attacking this cam http://eldgos.mila.is/eyjafjallajokull-fra-thorolfsfelli/

Between the ash on the lens of http://www.mulakot.net/myndavelar.html you can see the plume as well.

On the subject of sunsets sunrises. Yesterdays was normal this morning before cloud intervened was very red. Sadly cloud cleared it but I suspect there may have been very good sun rises to the east of us.

hvo tremor chart still showing an unusual rise that isn't reflected in the other charts.

If it doesn't stop rising soon they will have to resize the chart. As I think this one is near Katla I am begining to wonder what this rise signifies although it is on a really low tremor scale at the moment.

Actually only on one other http://hraun.vedur.is/ja/englishweb/tremor.html and that's based on the SE of the volcano. Perhaps a new sill is being injected in that area. Then all in the south east section are rising strange.

Is that the same one as this one (snb) which is just to the east of Katla?

http://hraun.vedur.is/ja/oroi/snb.gif

This rise has been slowly happening for quite a rew hours. I wish i knew the significance of it even though it is a relatively very small rise but it is just the difference between these two (hvo and snb) and the other stations around Eyafjallajokull that is a bit odd in my view.

At least it gives me something to watch while the webcams are obscured by ash.

[picog]

No new earthquakes appearing yet; in fact, it's been very quiet for a couple of days now.

[Crimson_Sprite]

has anyone noticed on this map here of the earthquakes http://en.vedur.is/earthquakes-and-volcanism/earthquakes/ viewing all of iceland, not just the earthquakes near Eyja, that on the actual map, there is hardly any red dots indicating earthquakes in the past 4 hours, but if oyu look down at the graph below, and on the table page/tab, that it indicates a flurry of quakes at about noon (1pm our time). I wonder where those are and if they will be placed on the map view?

Your right a swarm of quakes but they don't seem to have been plotted. Mystery deepens.

[nightfire800]

10 of them were all in the same place so you see them as one red dot. There are two tabs on the top of the map. One called map and the other table. Go to table and you'll see what I mean.

ahhh, ok, I see what you mean.. I didnt bother looking at the precise position of the quakes before, just assumed they would place loads of red dots in a huge cluster like they usually do, but I guess if they are exactly on top of one another, you can do that.

[LadyPakal]

An interesting stat for you from the Eruptions blog:

'Right now, the IMO estimates the eruption rate at ~200 tonnes/second. Lets put that in a little perspective - a Ford F-150 pickup weighs about 2 tonnes, so the volcano is eruption the equivalent of 100 full size pickups a second. '

[londonsnow]

does anyone know the phonetic pronounciation of the eyja volcano?

[SnowBear]

I think it is EYE-YAF-YALLA-YOOKULL

[londonsnow]

I think it is EYE-YAF-YALLA-YOOKULL

thanks SnowBear

[Crimson_Sprite]

Funny you should ask, as I have spent HOURS trying to say it. I think the hard part about it is the "ll" as there is no sound in English that makes their "ll" sound. Its a very soft rolly type L that is pronounced in the back and sides of the tongue. I saw it written this way though.

ay-yah-fya-LHah-yuhr-kuhLH.

Eyja-Fjatla-Jökutl

I still cant bloody say it though! hahaha!!

Edited May 19, 2010 by Crimson_Sprite

It has only 4 syllables.

A humerous guide to pronunciation:
