See also this report which in addition to other details contains this


SERNAGEOMIN reported that on 4 March seismicity from Llaima increased. During an overflight that same day, scientists observed emissions of gas and steam from the main crater. Images taken that day were compared to those taken on 21 February and showed no significant changes in morphology. The rate of sulfur dioxide emissions had increased, however. Scientists also noted deposits from a large rockfall along with fracturing of the glacier, especially on the upper N and NW flanks. Those observations in addition to the increased seismicity prompted SERNAGEOMIN to raise the Alert Level to Yellow, Level 4.


LLAIMA Central Chile 38.692°S, 71.729°W; summit elev. 3125 m

Looks as if the Chilean earthquakes may have woken this volcano.

Whilst wilfing around the volcano blogs I came across this:


Mount St. Helens ’spiders’ will get tryout on Chilean volcano (The Oregonian) – Geological ’spiders’ packed with instruments to monitor the heaves, sighs and belches of Mount St. Helens, are expected to migrate south this month. Two of the contraptions are headed to Chaiten, a volcano in Chile that began erupting in 2008 after about 9,000 years of dormancy. … The machines helped give the USGS sufficient information to declare in January 2008 that Mount St. Helens recent eruptive phase was over. That kind of certainty is needed at Chaiten, said John Ewert, a volcanologist in the Volcano Disaster Assistance Program. “It’s always hard enough to know when they’ll start erupting,” said Ewert, part of the team that visited the Chilean volcano in January. “It’s even harder to tell when they’ll stop.”‘

Some of the volcanic activity headlines for the past week:

•Llaima: steam-and-gas plumes detected, alert level raised
•Soufrière Hills: major dome collapse, resulting ash plume reaches 15.2 km altitude
•Nevado del Huila: gas emissions and thermal anomalies detected on the lava dome
•Tungurahua: ash plumes rose to altitudes of 5.5 to 9 km

All is quiet at Chaiten and it is looking good today.

When I took a look last night - in the dark - there was a definite 'glow' but I don't see much evidence of it today. I won't bother to post a picture.

Oops changed my mind. Looks as if the USGS spiders have arrived to survey Chaiten. They are MASSIVE!

Near West flank of Mt. Shasta y'all!!!!! I don't know, looks bad, how long's it been for old Shasta, since last eruption, just curious?

During the last 10,000 years Shasta has erupted an average of every 800 years but in the past 4,500 years the volcano has erupted an average of every 600 years. The last significant eruption on Shasta may have occurred 200 years ago

Thank you, that was fast..... and on a side note, did ya notice that 200 + 600= 800 yrs, just saying, not implying....

Soufrière Hills: major dome collapse, resulting ash plume reaches 15.2 km altitude


That's Montserrat, right? Watch prog on this just a couple of days ago and the last big eruption (1997?) was due to collapse of lava dome - the up/down inflation caused cracks in the dome walls which led to huge pyroclastic flows..

Where are you getting this? This is from the Montserrat Volcano Observatory

I can't see anything anywhere about this.

It's the same site you viewed, puterman, you just need to go back to Feb in the news archive

Apologies - my bad!

I thought you were referring to a new collapse.

Planchon Peteroa is in a stage three eruption. This is the Chilli-Argentina caldreras system that overlaps 3 seperate calderas that is in such a desolite area that they were not even discovered until reasently.
There was a thread on this a few weeks ago.

No doubt related to the earth movements this past month. Hope this isn't a monster awakening, and only a little venting.

Still trying to get some more details of this

eyjafjallajokull volcano erupts


Eyjafjallajökull volcano in southern Iceland has erupted after an extended period of seismic restlessness. The volcano began to erupt around midnight local time 20/21 March 2010. Civil protection authorities report that no-one is in immediate danger, but between 500 and 600 people have been evacuated from their homes. Pictures and reports indicate fissure eruption. Lava flows and ashfall have been reported and roads have been closed. University of Iceland geologist Tumi Gudumundsson is quoted by ABC News as saying that the eruption is located beneath an ice-free portion of the volcano, lessening the chances of a glacial flood being caused by melted ice. This could change, however, as the eruption develops.


More details when I can get them.

Addendum: Smithsonian description of the volcano


Eyjafjöll (also known as Eyjafjallajökull) is located immediately west of Katla volcano. Eyjafjöll consists of an E-W-trending, elongated ice-covered basaltic-andesite stratovolcano with a 2.5-km-wide summit caldera. Fissure-fed lava flows occur on both the eastern and western flanks of the volcano, but are more prominent on the western side. Although the 1666-m-high volcano has erupted during historical time, it has been less active than other volcanoes of Iceland's eastern volcanic zone, and relatively few Holocene lava flows are known. The sole historical eruption of Eyjafjöll, during December 1821 to January 1823, produced intermediate-to-silicic tephra from the central caldera.


The volcano is 'next door' to Katla - another one under the ice. There is a web cam for Katla but it does not show much. There is one for Eyjafjallajökull as well I believe and I am trying to find the link. The reason it does not show much is because the camera on Katla is facing 336 degrees (info given to me by Icelandic TV) so all it will pick up is drift. Incidentally this is a good webcam to look for aurorae.

Note also that I believe I am correct in saying that Katla is on alert as well, and has been for some weeks now.

Good link here.

Hekla web cam. See above for Katla cam.



I think the Hekla cam must be over subscribed!! I can't get anything.

There are at least 2 plots from the only IRIS station I can find which is BORG on the II network. These are showing nothing out of the ordinary. BORG.II.00.LNZ.2010.080
and BORG.II.10.BHZ.2010.080

I don't think we are going to get any fallout in Ireland as, just at the moment anyway, the wind is blowing in the wrong direction

Here is a better one, the aninmated screens of ash clouds

This link is to a video of the volcano taken around 8am UTC this morning.

That area if full of volcanoes. I was there last summer.
It's amazingly beautiful!

Hekla, Katla, Laki, Grimsvotn, are all nearby volcanoes.

Katla, which is a dangerous one, is very close to this one, just a few kms east.
Hekla, which is also one of Iceland greatest ones, is also 50km north, and has shown signs of an eminent eruption (which is nothing new because it has been erupting every 10 years)

I really recommend to anyone that likes to see volcanic landscapes to go there: Hekla, Laki, Thorsmork and Landmmanaugar

I picked up this snippet in the Eruptions thread.


I translated the Sernageomin link to swedish, and as I understand it they had detected the EQs from the Chaiten seismic network. Interestingly the origin of the earthquakes actually wasn´t from Chaiten but instead from the Melimoyu volcano! It is probably a nearby volcano. They also write that they are making an expedition right now to put up a seismic station at Melimoyu.

Melimoyu is a stratowolcano with a 8 km wide icecovered caldera. And guess what.... It hasn´t erupted since 200AD!

I just remembered that they did a study of Iceland recently. It sits on a plume that make Yellowstone look like a beginner. 150km across and over 400 km deep!

Wikipedia

It is just getting dark in Iceland now. On the Hekla cam (address above) you can make out the glow of the eruption the other side of the mountain. This must be a south facing cam.

Folks you might be interested in the NASA photo of my favourite Chilean volcano.

This was taken on the 3rd March so is very current.
