El Hierro

[pennylane]

James I agree. This thread is brilliant.
I'm not good with graphs and stats and stuff but the
info I've picked up on here also spurred me on to do
some googling myself about othe volvanos and also
the history of the Canaries, which is facinating.
I'd never given El Hierro a second thought before
but it's history is so interesting....
keep it up Jand and Fi and other interested contributors.
Like I said in another post, interested people will
read and be respectful....those who aren't interested
should just not pick up on the thread..

This is fascinating stuff jand........I love it and have learnt so much about volcanos and how they form etc.

I learnt recently that Teide is the 4th largest in the World!

Ignore the derampers - I guess they find intellectual pursuits a bit threatening or something.[][][][8D]

Surfjames, you probably class me as one of the derampers. But everything you need to know about volcanos is out there on the internet as Woe said. I admit I flick through this thread but I do not read the waffle on here. Most of what is pasted is some anonymous persons views, maybe they are on the island, maybe some of them are highly strung so reports are distorted by this. When someone started posting lots of posts on here they were posted in a very scaremongering or highly strung manner and that still shows from the very late posts and very early in the morning posts.

Wouldnt it be better if the thread was updated in an informative way and all the waffle was left out? This is only my opinion of course.

I have a doubt on the statements made yesterday and subsequently rectified by official sources, related new eruptive mouth...
 By that now rush to speak of only one mouth?

If I remember correctly, weeks ago you spoke of several mouths fisural system even here we did questions few mouths had really already that from the very beginning these, scientists spoke in the plural.

Even comes to my mind that image which seems a direct freight train to the coast of La Restinga and was compared to the fisural eruption of Lanzarote Dejo here the link of the video from this image that I say that clearly seen in the sea more than one... http://www.rtvc.es/volcanelhierro/un-proceso-similar-al-de-lanzarote-79607.aspx and also the image of the alignment of emissions...

This is very interesting to see and food for thought!!!

The alignment of the mouths that supposedly has the submarine volcano of the calm sea is similar to that which is produced on the island of Lanzarote in 1730.

This volcanic process left their imprint on nature with a place they call the route of the volcanoes. The image is very similar.

Fifi/SurfJames could one of you post the photo on the above link re the alignment of the mouths.

Thanks

As per TripleH  and the last rant (another stalker).

Just to reassure everyone reading this forum .

I am on Fuerteventura I do not take drugs I am not on any medication (except Ibrufon) I do not drink excessively.

I am one of the most level headed persons you could meet and had to chuckle when it was also said by TripleH highly strung which certainly is not me!!!!

As TripleH does not know my work/life schedule its also non of her/his business when I post comments on this thread.

Update 22/11 – 11:40
 Reader Paul Abuelo (a multiple commentator) attracted our attention on a sublime document entitled "The Canary Islands Hot Spot". The extract quotes : The Canary archipelago comprises seven main volcanic islands and several islets that form a chain extending for ~ 500 km across the eastern Atlantic, between latitudes 27°N and 30°N, with its eastern edge only 100 km from the NW African coast. The Canary Islands developed in a geodynamic setting characterized by Jurassic oceanic lithosphere formed during the first stage of opening of the Atlantic at 180-150 Ma and lying close to a passive continental margin on a very slow-moving tectonic plate – the African plate. In addition, the archipelago lies adjacent to a region of intense active deformation comprising the Atlas mountains, a part of the Alpine orogenic belt. Click here to read the entire document.

Hev, It seems that only about 3 people are interested in this post. Jand, Fifi, and SurfJames. Tremors are happening all the time around the Canaries. There was one yesterday in Gran Canaria.

With jand´s Beligerent attitude, Admin should relegate this post to the Dross section.

If people are interested as to what´s happening in El Hierro thay can go to Canarias7 Online, where they have a special section updated as things happen. There they can cut and paste into Google or Bing Translate, just like jand does.

The Civil Guard helicopter unit and the INVOLCAN detected a sudden emission of gases to the South of la Restinga

The sudden discharge of volcanic gases was recorded on 11: 40 pm yesterday Monday, November 21

Scientists of the Institute Volcanológico de Canarias (INVOLCAN) have confirmed to the direction of the Special Plan of Civil protection by risk volcanic of the community Autónoma de Canarias (PEVOLCA) the observation of a new sudden discharge of volcanic gases by the Civil Guard helicopter unit in the Canary Islands at 11: 40 pm yesterday Monday, November 21. This visible emission of volcanic gases was located approximately 200 metres of distance to the East of the main area of emanations of gases and volcanic materials that occurs South of la Restinga since mid-October, 2011.

Following these remarks made by the Civil Guard helicopter unit in the Canary Islands, proceeded to make decision and acquisition of thermal imaging in air mobile position associated with this new and significant process of degassing by underwater volcanic activity with the human and technical resources of the INVOLCAN in the framework of the agreement of collaboration between both institutions on the implementation and use of thermography to strengthen volcanic monitoring in the Canary Islands. To return to the area with the scientists of the INVOLCAN, the intensity of emissions disappeared, as it has happened on some previous occasions (November 4, 2011). These observations confirm the existence of pulses or sudden discharge of gases by underwater eruptive activity south of la Restinga disappear later but which are of a great utility to detect and locate new sources of emission or eruptive mouths associated to this volcanic process. The geographical coordinates of this new sudden discharge of gases has been North 27th 607547 - West - 17º 991288.

Actually - can I say that this is an interesting subject and I too have looked things up and would like to discuss what is going on via this forum.  But alas, I really don't like anybody making a big drama out of this situation and I hate misinformation.  Some links & photos are useful but the endless cut and paste posts, to me, are meaningless drivel. Thats my point of view.

Sorry but I have to agree with TripleH, Woe, Hev, Florence and Digsley. Enough is enough. Anyone with any interest in El Hierro has enough info to do their own research. I only logged in for Kevin2003 and he's even given up. Why don't you just email each other the updates. If anything dramtic happens, I'm sure the media will inform us. Still on page 5 Deso.

[SurfJames]

Update 22/11 – 19:49
Ian Carson was lucky today. He was most of the day in the North of the island and at his return to El Pinar
he was able to take images from today's new activity. The activity is far more than we could see on the webcam.
Ian's pictures are showing multiple emitting vents (as far as we could see on the picture mainly degassing (blue color))
, although it would not surprise us that also magmatic material will have been ejected. As you will on the image series,
 the Guardia Civil – Involcan helicopter arrived also above the stain but unfortunately when most of the activity had subsided.
  They will certainly have beautiful pictures as they are very close to the vents waters.

So it's true, we have multiple vents opening, and they appear close together. I'm not sure whether they are away from the island, or closer
to it, but looking at the webcam yesterday, there did seem to be activity very close to the harbour mouth.

This isn't good news!  There have been predictions that the island might get split into two, along
the line of the earthquakes.

It will be interesting how this thing plays out!

This is what all the islands sensors picked up.

Copied From Avcan

It is curious to see the brand which has left this earthquake in seismographs of the network of IGN in the Canary Islands, at 18: 58, 10 minutes later, in the form of wave that lasted more than 6 minutes. And that was at an estimated depth of more than 500 kilometres. And see the results.

Update 22/11 – 23:00
Ian Carson mentioned also that he was 1.5 miles from coast and the 'vent & stain'
was one mile off shore also, there was a howling gale to vibrate the camera.. He said
he was getting a bit worried at one stage as more spots were appearing. You never know....

You can see photos of the multiple vents here:

This has been noted by someone else dont know if it means anything though?

There were six quakes in a row this morning that had a depth in the teens, two of them at 15km., before we broke the trend with a depth of 20km.

1114314 22/11/2011 23:55:45 27.7956 -18.0578 15 1.9 4 NW FRONTERA.IHI

Seems the trend is showing more shallow quakes. Of the 26 EQs today on the >1.5 mag chart (actually yesterday the 22nd) 14 (53.8%) were below 20km.

For the 6 EQs listed so far for the 23rd, 5 are below 20km.

It might well be. Fissure eruptions often have inflation few days to hours before a eruption starts on a new fissure.

What town is closest to that area ?

Where does an inflation of 1.5mm come in the scale of such things for example compared to the eruptions at Eyjafjallajokull.

Eyjafjallajökull volcano did inflate 60 mm before it erupted. In Krafla volcano inflation and deflation was measured in meters (hundreds of mm) when magma moved around.

And I aint gotta clue Karen or Lurk, but we HAVE to start plotting the stuff above sea level.

Reason for that is that if it continues either Restinga will come popping to the surface and rise out of it and its going to be very dicey to plot that mug, or it will walk up out of the sea onto land either at Restinga or El Golfo. Or it will make land that will demand it of the plots.

You guys are COOOL with this stuff in my book. If I had time to try I would but its Xmas and its airplane time for the stuff that didnt make it for Black Friday.

A fluctuation like that is what is needed to bolster the Sun connection. In this case, it's probably the Sun connection to the mount or building heating up on one side.

That would be my guess. The signal doesn't seem to show up anywhere else.

Red Light, Level 1, in the Restinga (El Pinar)

Yellow light in the rest of the island

In consideration that the risk of volcanic activity is complex there are a series of actions that develop sequentially. Therefore a worldwide warning system has been established for the population based on the selection of three colors (green, yellow and red).

In this way the population may adopt certain behaviors based on the symbols that are easy to understand by color. We all must adhere to those alerts and the recommendations relating thereto.

Has anyone considered that there could be an underwater fissure eruption North of the island? With sufficient depth and current, there might be no signs of it on the surface.
