El Hierro

Consensus. The researchers matched non-tip and Tuesday IGN coordinates and images taken on Monday from a Civil Guard helicopter and agreed that the emission pulses photographed are located in the fissure through which the volcano is already manifesting .

After two weeks of relative quiet, the volcano of La Restinga returned on Monday to be seen. Minutes after half past eleven crew of the Civil Guard helicopter which monitors the exclusion zone around the outbreak and collaborating with the Institute of the Canary Islands volcanological (non-tip) captured a new emission pulse gas that was initially identified as a new focus eruption. Researchers from non-tip and the National Geographic Institute (IGN) differed Monday on the site of the new and ephemeral bubble, but yesterday agreed that probably corresponds to the same area of the active fissure eruption since October 10.
The direction of the Special Plan Civil Protection Volcanic Risk (Pevolca) confirmed early in the afternoon yesterday, the images taken by the Guardia Civil for non-tip is "correspond to an emission point located in the direction of the crack."

This fissure is "fit" the volcanic cone and main broadcast center since the eruption began.
The intense bubbling points have already appeared on other occasions and have also been photographed, as happened on November 4.

IGN is responsible for volcanic surveillance in Spain and which forms, together with the Higher Council for Scientific Research (CSIC), the scientific committee that advises the Pevolca, and researchers from non-tip, which is a guest on the committee, agreed yesterday that captured images, but none could then check again part of the degassing process which "confirms the existence of shock or sudden pulses of gas by submarine eruptive activity subsequently disappeared, but are of great use to detect and locate new emission sources or mouths eruptive volcanic associated with this process, "summarized the two agencies through Pevolca.

Researchers placed the new non-tip gas discharge at 200 meters east of the main zone of gas emissions and volcanic materials according to the coordinates given from the helicopter. However, IGN claimed yesterday, as on other occasions, that the coordinates from the air has "a mistake." They have therefore placed buoys at sea and have been instrumented ground reference points to triangulate the area of #8203;#8203;the rash.

Update 23/11 – 07:50 – La Restinga Webcam saga (continued) – is everybody sleeping ?

We are sorry to use such sarcastic words in this update title, but we are highly irritated by the amateurism of professional telecommunications operators and local authorities. Local authorities are simply NOT aware of the island promotion capabilities  of these webcams. A letter Earthquake-Report.com wrote to the president of the Cabildo, Mr. Alpidio Armas is still unanswered. The Cabildo, Telefonica and the El Pinar authority did us (and scientists from all over the world) a favor in installing them, but fail to operate them properly reducing the value to 25% of the capabilities.
 Thousands of people are following El Hierro on a daily basis via Earthquake-Report.com. The difference in between the pictures from Ian Carson and the Guardia Civil Helicopter overflights at one hand and what the webcams are showing on the other hand is striking. We know of course that it is impossible to obtain the same results with a webcam,  but it can be at least 4 times better than what we see now. Here are a few of our irritations and frustrations.
 - The El Pinar Authority / ACN Press webcam shows the sea but nothing else. Nothing is done (not even on a daily basis) to direct the webcamera to the stain or activity areas. Sending somebody to the camera (at least on a daily basis) and positioning it with a cellphone in communication with somebody looking on a screen is enough to make the output a lot better.
 - The Telefonica / Cabildo webcams are a story of initial good intentions stuck in ... who knows
 - The promised El Golfo webcams have NOT been installed yet.
 - The La Restinga view webcam is unsharp since yesterday afternoon, which means that NOBODY looked at it since then !
 - The eruption webcam, the most important one to give us a clue on what is going on, is operated on a  "when we have time" basis.  This morning the view was again completely out of the activity angle. It takes mostly several hours before somebody looks at a screen to see that the webcam has to be redirected. As Ian Carson made a picture from the mast and the webcam, we know that this webcam is operated from a distance, so it can be redirected to to exact angle almost continuously.
 - The webcams are definitely NOT HD and the material used is inferior to what the quality of such a high yield webcam should be.

We think that Telefonica / Movistar is to blame for the unsatisfied operations. Telefonica is a WORLD TELECOMMUNICATIONS GIANT and should behave like this, not like an amateur. In case of the poor island of El Hierro, we could eventually pardon the local authorities, but this does not goes up for Telefonica / Movistar.

Harmonics seem to be spiking a bit more.

Update 23/11 – 17:01 – La Restinga Webcam saga (continued)
 The webcams are certainly not operated by people who are acquainted with volcanic matters. Instead of focusing on the vents (in front of the harbour entrance), the webcams are following the stain who is carried to the east by the sea currents. Only the  active vents are important at this time.

If the Government had been willing to pay for the Telefonica ship which had the proper ROVs to go into an eruption zone it could have mapped the area and we would have known the exact locations, depths, and an approximate time of major eruption because it would have shown how close the cone really was to the surface. The Ramon Margalefs scanned images from a distance are not accurate. Such a pity they wouldnt spend the money.

Technically speaking the Island of El Hierro is erupting. It is just not above the ocean yet.

The volcano in El Hierro will not come to the surface

The submarine volcano is occurring at 300 meters deep in the area of La Restinga of the island of El Hierro, "not come to the surface" according to Jose Luis Barrera, volcanologist and Vice-President of the Bar Association official Geologists (ICOG)

For barrier, "as are evolving events, does not seem to be coming to see the popular 'Rooster tails', or eruptive Tufts". The crater of the submarine volcano continues to about 200 meters deep. "It is possible that part of its structure has collapsed because lava running down Canyon and the cone does not grow in height", recognizes the volcanologist.

The volcano of La Restinga came up to 300 meters deep and in 14 days, soared about 100 meters, a growth rate of about 7 metres a day. "If I would like to progress height would be required that the base ensanchara significantly to stable growth in the vertical, which is a huge volume of material that does not seem to occur," admits.

The unique external signs showing the volcano are "the bubbling, and less and less," explains. However, Saturday November 5, there was a small subaerial eruption, so the "explosivity index has had to be high" indicates barrier.

"The pressure of the magma has surpassed the level of pressure marina and sporadically, has entered the second phase or hidromagmática phase".

"Although both geologists and people are very keen to see out an island and revitalize the tourist attraction of the area, is clear that the volcano has taken another way," concludes the Vice-President of the Association of geologists.

Goodnight everyone. Sleep well.

Interesting stuff.
The saga continues...and I for one are indebted to Fifi Jand and Surfjames for their posts.  Its a hugely fascinating occurrence and many of the posts on this thread provide interesting links...which in turn provide differing viewpoints and opinions. Its up to the researcher to pick and choose what they feel is genuine or scaremongering/hearsay. Its handy to have one point of 'entry' to all that is being said on the web regarding Hierro, I have discovered lots of links via here...some I can agree with, some have left me scratching my head! but all very interesting for someone with only a GSE in Geology...and no qualifications in island politics!

Saying that some of these posts has ruined their holiday is bilge really....research, evaluate, make your own mind up and do your own risk assesments....above all, don't shoot the messenger!

Eh-depends on how you look at this Larz. The entire island could erupt? Not likely but if it breaks into the inner workings of El Hierro there are going to be vents popping up all over the place. IMO I think thats happened before. Its kind of nutty but I couldnt find a single hot spot that you would normally expect with just about any other volcano.

This island is described as the island of 10,000 volcanoes and there are thousands of vents there but no heat until recently. Like 90 quakes before July in the last 10 or 20 years.

But if it does get into the dikes, the lava tubes, the collapsed cave structures you just wont know where its going to pop out mostly because they are open at the top.. No pressure, no quakes and it could rise quietly and just show up.

I thought it was extremely significant that the Co2 levels are still rising. Dont get that unless something else is happening and Gitta at Eruptions has a tube of a new vent opening off of Restinga.

That big blob of supposed magma in a chamber really likely doesnt map out the chamber or the conduits. They could be right below their feet in Frontera and they wouldnt know it. Its just not what we are used to. It goes without saying that it wont happen in a vacuum... If its going to go its going to go quite noisy and very likely with no warning. A big quake, a flank failure and all sorts of bad news could come to the top very quickly.

Do get out a topo map of the place and you will be amazed at the number of named vents and the thousands that arent.

I just think that if it gets into the island that its going to exploit the plumbing and its going to pop out all over the place.

Update 23/11 – 22:00 UTC
Ian Carson returned tonight from an exciting action day at the Las Calmas sea. He could take a lot of colorful pictures. Click on the thumbnails below to watch them in full size.
 Ian also reported the following :
 An interesting day. Started at 0830 with my morning run but it was damp and 12 degrees in El Pinar so went 10 km to La Restinga where it was 19 degrees and Sunny - I could run in the warm and watch the sea. Nothing visible at normal vantage points on way down but after run (on way back to Hotel for shower/breakfast) it was clear there was activity. Checked phone and seems harmonic burst at 0930. From 9.30 onwards Jacuzzi seemed to invigorate and turned the whole sea blue/green with the stain. At one point, as far as the eye could see when I was joined by Joke. The stain came right into the coast and there was a thought that two vents were in action as these were seemingly two independent stains, however, it seems the stain was moving both right and left and swirling around the bay. I stayed there in La Restinga up and down the vantage points all day until 1700 ! At around 16.30 there seemed to be a lot of dark brown material at the vent of yesterday, I can't say for certain there was ejected material but you can judge. I walked up the Naos volcano cone (160 m) and took more pictures, the beauty still amazes me.
At times there was a feeling today that something was going to happen, sitting on rock it felt like ground trembling but the wind was gale force making it a bit difficult to confirm. This must be playing havoc with the webcam !

Thank you for your comments.

[SurfJames]

Wow - Hi Guys....Just come in after spending the night at my girlfriends and things are really moving now! The whole sea has turned blue/grey. []

We have entered stage 2 where the magma pressure is equal to or above the sea water pressure. We may well see rooster tails soon.

Fifi - that's a stunning picture you've posted above. The crew on that boat are a brave lot!!! [][]

It is estimated that there are currently 5,000 active underwater volcanoes worldwide; of various sizes, standing alone or forming ridges with other volcanoes, of which the highest ones will rise above the surface as islands. The submerged part of the Hawaiian Islands, for example, is one of the largest and longest volcanic ridges – more than 2,400 km (1,500 miles) long. [8D]

[fifi]

Good morning from wild and windy Dublin. Thanks for your comments Surfista and Surfjames[] I have had a look at a few papers and they seem to be saying the same as the article that jand posted yesterday about a possible collapse of the cone. I am guessing that this can only be speculation because the area has not been mapped again. I would be disappointed if I thought I was not going to at some time see my Rooster tails appearing but the cone would need to be about 100 metres from the surface for that to happen although as Surfjames mentioned if there is enough pressure it can happen from a lower depth.

There have been no earthquakes since 1am, so energy is being stored again at the moment.





Magnificent colours. Photos taken yesterday.[]

Some stunning pics Fi but them mugs in the boat are off their heads......[:0]

[SurfJames]

Hi Fifi....wild and windy Dublin! Lovely and also the perfect excuse to dive into a pub, play some Irish Folk on my guitar and enjoy a pint of Guiness. The last time I was over there I went to Dingle..is the dolphin still alive? I think he was called fungi...or soemthing like that. And those blasket islands....what a haunting beautiful place.

Yes - we want some rooster tails !!!! [][][8D]

[fifi]

Sometimes it looks as if the boat is really near the eruption area Paddster when you look at the webcam but I think they keep a reasonably safe distance. The photos are amazing allright. Pity they dont have a webcam in the air so we could have a decent view.

Yes Fungi is still alive and well in Dingle (there are a few with the same name so he will live forever[][]) Its one of my favourite spots in Ireland too Surfjames. Too early in the day for a pint of the black stuff. Maybe later.[][] BRING ON THE ROOSTER TAILS....WE WANT THEM NOW.[][]

Nothing wrong with kids programmes, in fact the rest of the producer would learn a thing or two by watching them.

We want TV to entertain us, make us laugh and some news.   Not the continual news and drivell that we get just to use up air time.
I personally would rather pay a bit more on my license for decent programmes and no ads.   Dont know why I have TV with so many channels as only watch BBC 1, 2, 3, & 4 except of course if Deadenders is on then BBC gets knocked into touch.

The non-tip Continues Registering an Increase of the diffuse emission of CO2 by the volcanic island of El Hierro system

The diffuse emission of carbon dioxide (CO2 by the volcanic edifice Currently island of El Hierro) Reach the 2.186 ± 87 tonnes per day

Since last July and Scientific Institute of Technology for Renewable Energies (ITER), body dependent on the Cabildo Insular de Tenerife, and now forming part of the Institute volcanological de Canarias (non-tip) 8.500 Have Been Further steps of diffuse flux of carbon dioxide (CO2 ) in the island of El Hierro Numerous scientific Through Campaigns on Emissions of volcanic gases diffuse That Have Entire island materialized in the surface of the island of the Meridian. To date, the results Reflect the registration of an upward trend of the diffuse emission of coal dioxide (CO2) Into the atmosphere by the volcanic island of El Hierro edifice, Who has Reached the 2.186 ± 87 tonnes per day, a value equivalent to 6.34 times the average normal value for the diffuse emission of carbon dioxide (CO2) in the island of El Hierro (345 tons per day).

The purpose of these scientific surveys to assess spatio-temporal variations of the diffuse emission of carbon dioxide (CO2) into the atmosphere by the volcanic system island of El Hierro in the context of the recent seismic-volcanic crisis Island Meridian . On the other hand, realize the reasons for this type of scientific stem from the inability to obtain such information through permanent instrumental networks, to be absolutely convinced that the gases are the driving force of volcanic eruptions and the importance of Carbon dioxide (CO2) in volcanic surveillance programs because it is the second major component of volcanic gases after water vapor, and its low solubility in molten silicitados - magma - making carbon dioxide (CO2 ) to escape with their ease of volcanic systems in depth.

These scientific surveys have failed to materialize due to MAKAVOL project "Capacity Building of R + D + i + d to contribute to the reduction of volcanic risk in the Macaronesia (MAC/3/C161)" which is being co-funded by the Transnational Cooperation Programme of the European Union Madeira-Canary-Azores (MAC 2007-2013) and the collaboration of the Island Councils of Tenerife and El Hierro.

Non-tip is an institution demanded unanimously by the Senate (2005), Parliament of the Canary Islands (2006) and House of Representatives (2009) with the aim of contributing to improving and optimizing the management of volcanic risk in Spain.

The Chilean volcano Chaiten entered eruption without warning by the rapid rise of magma.One of the reasons why a volcano warning not can be the physical properties of magma which, in this case was sufficiently fluid and float to rise rapidly.The case of the surprise on November 3, 2002 of the Reventador volcano eruption.In those volcanoes troop magmas of low silica content, rich in gas and very fluid, the ascent of magma into the duct may be asismico, fast and without warning. So, this eruption is very useful to remind the scientists, civil defense and to the authorities some volcanoes can revive with violent eruptions, without further notice. (Translated by Bing)

Update 24/11 – 19:36
 - 5 earthquakes since midnight
 - the last 2 earthquakes at a depth of 15 and 16 km
 - medium harmonic tremor with regular bursts
 - Ian reported that the bursts on the harmonic tremor graph are coinciding with stronger activity in the stain, although he also said that he could not see magmatic material floating to the surface
 - Some people talked of a sulfur smell in the El Golfo area. Inspection teams have been examining the situation. Their findings are not yet known. Ian, who also went to the El Golfo area today, could not confirm the smell.
 - GPS deformation of the island is showing an inflation of the Tanganosoga volcano area and a deflation of the La Restinga peninsula. The data used is from November 10 until November 21. Click here to read this article.
