Assuming A) that the magma was under less pressure...
 ((B) that the signals from 5 AM UTC have been explosions C) that the drumbeats that we're seeing indicate that the pressure of the magma is equalizing the pressure of the water, and have therefore been in mode 'machine steam'... CHu... Chu... Chu... Chu...
 (D) assuming that the signal of treamor we've seen indicated pressure of magma trying to leave and not the amount of magma coming out.(same amount, less output = greater signal;) Same amount and larger output = less signal) E) Suponindo that the tremor signal did not indicate the degassing of the magma (major tremor = more magma desgasificandose, more bubbles) F) seeing that it is not signal on surface... is it possible that it has closed the mouth shallow, and one greater depth fissure has opened?by where is releasing more lava, but less pressure?
 Is it possible that being at greater depth, is called pressure of magma and Navy and so pulses occur in the tremor?

I do not know that is... but something has changed in the volcano of iron at 5 AM Utc today (except that, as someone has said, the volcano itself is spending a good April fool) (Translated by Bing)

It turns  out that the news about Tenerife was actually an April Fools Joke as today in Spain its their equivalent to April Fools Day and somebody posted a graph from IGN showing tremors between 0800 and 0900 near Teide.

A particular view: I have the impression that the submarine volcano has released the final pedorreta after a long deposition.
About pedorreta say that in the light of the backfire end.

And here's a theory: pressure balance is broken agua-magma - gas and this, it has penetrated the rift ending up causing rapídas evaporation and the consequent volcanic "bloating" in the form pedorréica.

The result, would be the crystallization of magma near the fissure and the practical seal thereof, "peristalsis" movements of magma not circulating already and therefore of the tremor to impede.

However, the digestion is not over... you would expect an increase in bowel sounds in the form of seismicity, and who knows...

It is the specific heat of water is more 4 times greater than the molten basaltic in terms of mass, and although the basalt is three times more dense than water, the water still has greater cooling capacity comparing volumes. For this reason, maybe that it has also broken the thermal equilibrium that prevented the crystallisation of basalt. But... does not want to say that the magma dead-end not continue pressure... simply does not flow as so far because that water cools faster than the volume of magma contributed than before...

This residual pressure could have still enough force to cause the opening of a posterior fissure after an eventito of fire? It would be in the salt sea or land where no cools both magma by lack of water would be?
Contrateorías and opinions are allowed, the discussion comes light.

By the way, is that it is not liked by many but must be read to everyone under my opinion and that is why left part of the Chronicles of yesterday which are of great interest of the people of the Canary Islands volcanoes: "Chronicles of 28 December 2011."

La Restinga felt vibrations last dawn
Her passing night the tremor experienced a very unstable behavior. La Restinga perceived vibrations as we were informed several neighbors who were awake at dawn. They coincided with the pulse of the tremor reflected on the seismogram between the 05.50 and 06.00 h in the morning. Subsequently the tremor had a descent progressive reaching a very low amplitude that was not appreciated in the whole eruptive process. As confirmed Carmen López "can not ensure that this is the end of the eruption because the tremor has not disappeared since that remains twice the range of normal values prior to the eruption". "Look for more time to confirm trends in one or another way, in fact as he advanced in the afternoon is slowly recovering."

"The rest of the island stations recorded signals by studying"
During our stay in the capital during the afternoon, we could observe the appearance of several signs in other stations on the island throughout the day. The most striking registered stations West of the island namely Orchilla and Julán although it was also observed some in the Gulf area station CTAN or the CCUM. When I asked the IGN staff asked us caution in the interpretation because some of them only appreciated in a single season fact to increase the chance of human origin.

The underwater eruption was activated at dusk.
La mancha during most of the 28 of December appreciated little active and many times very diffuse to the extent that it was difficult to locate its header. At approximately 17: 00 h knew of the issuance of a new eruptive pulse. To the transfer to our Observatory including volcanoes of the Canary Islands at the top of the cone next to La Restinga observe a manchon rounded with a light bubbling of whitish repeated minutes before nightfall. This gives us to understand that the continuous underwater volcano activity despite the reduction in the tremor.

Hi All, I think this may relate to El Hierro.....

I have been looking at Yellowstone for a couple of days, mostly at Pelican Cone, Mirror Lake & Madison River stations.... There has been some weird activity going on since just before Christmas.....Note: Pelican Cone Station has just been turned back on after 8 years....Here is the graphs for the 25th December:

Pelican Cone:http://www.isthisthingon.org/Yellowstone/wrapper.php?file=YPC_EHZ_WY_01.2011122500.gif

Madison River:http://www.isthisthingon.org/Yellowstone/wrapper.php?file=YMP_EHZ_WY_01.2011122500.gif

See how all the stations are picking up something from around Pelican Cone......This has been going on since with some random bursts here and there.......
 Around the same time as El Hierro graph flat lining today, Yellowstone's Pelican Cone & Mirror Lake Flat lined as well and there has been nothing since......

Pelican Cone: 28th December

Mirror Lake:28th December
 http://www.isthisthingon.org/Yellowstone/wrapper.php?file=YMP_EHZ_WY_01.2011122800.gif

Can you tell me what you think about this as I do find this weird......There is a thread on GLP, I know, not the best forum but there has been a good thread posted on there about this and there hasn't been any answers whatsoever to what has been going on.......I know that winds, malfunction, tree root rocking and construction have been ruled out..........Does anyone have a clue whats been going on there?

Also, find it strange how they recently just turned on the station there and NASA's Landsat has found anomalies at Yellowstone saying that power companies too have been picking up on activity outside of the park's borders.......

Any thoughts??? Thanks....

Actually it looks like the pressure is increasing a tinsy winsy bit. But it is still far to early to tell. But sofar today we have had 2 quakes.
 And if there has been a blocking event in the feeder of Bob so that only small amounts of gas is passing, then we should soon start to see more quakes occuring.

What I think happened is that the feeder of Bob caved in yesterday. And I think this was a permanent blockage of the system. The pressure is as far as I know not relieved really. There has not been any large subsidence, so the pressure should still be fairly high. And if then the feeder is blocked for solids, and soon will be closing for gasses as the plug starts to solidify, then pressure should start to go up again.
 The next week will be very interesting to follow the seismic lists for El Hierro.

As Lurking pointed out, what is the tremoring that is so clearly picked out on EHIG and EGOM? My guess is that it is the actual feeder tube. And that it returned on the CHIE plot as they dialled it back up again after the disapearance of the signal. And if it is the noise of the deep feeder, than we will soon see more action. Question is just when is "soon"?

Time will tell.

 Besides the beautiful stain most of the day, Julio was amazed to find Smoking Lava Stones in his time lapse of the day.  The smoking lava stones show up at 18:38 UTC while the harmonic tremor was slightly up. The video went too fast and finally the SLS could not be seen. He captured however a few images from that particular moment.
 Those people who want to see the time lapse of the entire day can click here. A full day is compressed in only 6 minutes.
 We at Earthquake-Report.com are recalling today's smoking lava stones to "Smoking Birthday Stones" and are offering them virtually to Joke for her birthday. Running slopes up and down, trying to find out the latest details just like a professional reporter, and this on her birthday, not too many people will do it. Happy Birthday Joke !

 Joke has already seen the raw video of the Salvamar Adhara. She told us a lot of details of what she has seen and we are convinced that it will be very interesting. The video will be published later today or tomorrow. IGN

Ideal! It was the last thing I needed to hear, but good is that you think that the volcanoes are lambs... well not agree...
For example about Hawaii, of what you speak are 62 eruptive episodes and thousands of people were left without home, gases, lava, explosions, earthquakes, tsunamis, ashes, faults, landslides... to say nothing of the destruction of... roads, houses, infrastructure of all kinds, natural areas, cultural heritage, vegetation, and of course some deaths to make it a paradise barren and lifeless for a few hundred years...

Gave the Jack Lord, who a few days ago was evacuated, of was where the lived and volcano has thrown all its neighbours, falling only the.... and the barred the door by that also has taken him, although his home still remains standing.

Careful what you wish sergio, a volcano is not any toy, nor is harmless.... well just the opposite is like living with a herd of elephants, buffalos, rhinoceros and gorillas crazy at home and think that you won't spend anything... the truth is that at any time you may pass over and you can not do anything to prevent it.

We have already spoken of what could happen in the Restinga and one of the provided scenarios, is not the worst, hablaria delete the map that population, not would be nothing.... don't think wish it's Ideal!!!! especially to people who might lose all all all they have.... (Henry)

PS: Sergio not you take it badly, but this is result of a terrible, LOUSY education VOLCANIC per part of authorities to the population LOCAL of the iron not making them aware of the real danger that have less than 2 km away from the door of their homes. Fear not, warning if and be prepared.(something that is not the population).

Juan Ramón is understandable, I understand this position, to my I love volcanos, the geology, and water... so I have a terrible respect... nobody wants to pass anything, especially that there are no personal misfortunes... but this is not a movie, is the reality, and you can pass anything, so my wish is that this ends as soon as possibletherefore with this volcano started the risk exists and increases as you approach the eruptive zone and duct...

Every day there is erupted there is a risk and it is significant in the Restinga, now this stable, but for how long?...and when has shown not to be... What has happened?, that the evacuation of la Restinga has been by security. The authorities have also raised such a scenario, as I say is not the worst. It is good that people know these things.

Continue and exit to the surface the volcano in his current position, you would at 2,5 Km from la Restinga.
 The greatest danger would be in the phase of explosions hidromagmaticas, where the explosions often reach several kilometers in height.
 The problem is that if the energy of the explosion is able to throw a rock several hundred meters in height, it is also launched horizontally... at greater distance.

As shooting MRU... I knew something....
 If the volcano is capable of launching a rock (of size that is) vertically more than 1000m in tyre MRU that same rock, with the same explosion, but released under certain angles, could reach la Restinga. Is the size that is.

(to achieve 1000m, 400 kg is needed 140 m/s in the explosion.) With the same speed of output but fired with an angle of 45 ° reach 2000m with those 400 Kg) eg: an explosion capable of launching a piano (400kilos) 2 km in height, has a speed of 200 m/s output. With the same speed, but if shoot you at 45 degrees, would be capable of launching eses 400 Kg 4 km horizontal...
 And do not want to calculate the damage that can make a rock of 400 kilograms falling...

So better that the volcano will remain under water...
 Although it would be wrong that it would be near the surface, to get any performance in the future.

There are a lot of worrying comments from people on the Avcan FB and on the other sites at the moment some of it relates again to the sometimes daily machine malfunction of CHIE and some to the withholding of important information from the bathimetrys.

I'm certainly tired and weary of the submissive sheep scientists and politicians of PEVOLCA ...
The damage that these submissive sheeps have been to the dissemination of science is irreparable ...
The power of having access to the bathymetry in more or less real time would have allowed us to learn cause and effect of the tremor in relation to developments on the stage.
 Institutes had full autonomy to publish and have become submissive sheep PEVOLCA volunteers.

I am not political but I can understand the worry of the Islanders . Also I do not wish to scaremonger as the behaviour of Bob does not directly have any effect on my life, livelihood or home, but I do have my concerns as a normal human being and scientist..
 What worries me most is the fact that there is a fairly rare occurrence happening and presumably all geologists dream of being able to forecast earthquake and Volcanic behaviour.
 Why then is the recording equipment, including the cameras so badly managed? How can accurate records be kept and analysed?
 This is so ridiculous that I too wonder if there are other recording and observation sites that ARE being kept secret. I really cannot believe this nonsense. I honestly think that there is just plain bad management. If a tiny country like Iceland can monitor their moving and restless land and keep their people informed every minute of the day plus extremely well organised emergency plans for keeping their people and livestock safe, then why can't a big country like Spain do the same?

I see Bob is closer to land......what really worries me is the position of what appear to be two cinder cones right in the village of La Restinga. This suggests that the fissure has in the past come to the surface there. I really feel so much sympathy for the people for I am sure they too are worried sick about this continuing eruption

 Politicians with cowards scientists asked all the dates were to PEVOLCA.
 The first person I heard asking this was María José Blanco from IGN Hierro.
 The Ieo was the owner of Margalef and had autonomy to publish bathymetry...
 It only happened in the begginig when Eduardo Fraile (mission chief) and Juan Acosta Yepes (chief of bathymetry) published their bathymetry IN LESS OF 24 HOURS on november 13th.
 Juan Acosta Yepes finished his mission time and came back to Madrid.
 While the hard line of PEVOLCA (politicians and María José Blanco of IGN) coul win the battle for the LAW OF SILENCE...
 A martial law how we were living a national emergency.
 A martial law to silence the IEO and CSIC with autonomy to publish and citizens could to know information quickly.
 All the dates must be directed to PEVOLCA.
 IEO didnt publish after Juan Acosta Yepes and Eduardo Fraile.
 IEO said us that Csic (owner of Gamboa) had autonomy to publish Gamboa´s bathymetry.
 The same story what hapenned with IEO, happenend wit CSIC.
 They were caught under the law of silence of PEVOLCA.
 The only one dates that PEVOLCA tell us quickly are when these dates are better.
 The volcan profile on 22th december was processed in 24 hours to tell us volcan had descenden 20 meters and we can eat the grapples wiht hapiness...

When you look at El Hierro on the satellite view on Google maps there are volcanic craters and cinder cones dotted all over the island, including some in line from the ridge to La Restinga.

My concern is that what we have seen from Bob is largely de-gassing with a few pyroclasts on the surface. We do not know what the magma is doing and we do not know whether or not the authorities know – a PR issue or just the type of eruption?

Update 31/12 – 11:07 UTC
 - The Restingolitas, as the Smoking Lava Stones are called in El Hierro, are coming up at regular intervals. As our 2 good webcams are having server problems (also the Frontera webcams are down), we have to stay with the U-stream El Pinar webcam. He has a fairly good zoom, but as this is a fixed camera, he shoots almost always to the side of the SLS. The stones can be seen on the wide angle though.  Keep looking.

I would not like to be in an apartment if car sized rocks started to be lofted into the air.
 But judging from the strength of Bob I do not think that it is likely that it would happen often. But I would not rule out one or two coming flying in the direction of La Restinga sooner or later. Especially if Bob starts to break surface.

Scientists could appreciate last Friday pyroclastic large onboard a vessel Salvamar

The volcano in El Hierro still emitting magmatic material steamy and large size, as were able to see in the morning on scientists Friday of the National Geographic Institute (IGN) since a vessel Salvamar of maritime rescue.

On Thursday intensified the broadcast in the area of header where appreciated I burbujeo and material fine. Furthermore, the Green Party was defined throughout the day.

SASEMAR 103 mission report, notes the observation of three very small broadcast area and corresponding drift of material into the South because of the conditions of the sea and prevailing winds. Emission points the water temperature was 17.5 ° C, while the temperature of the water clean near was 19.6 ° c.

The tremor signal behavior

During the day yesterday, Friday, December 30, the tremor signal recorded by the seismic monitoring network stations maintained throughout the morning the same level reached the previous day. However, increased slightly its amplitude at 09: 30 hours, coinciding with the issuance of fragments of lava surface and it was also observed some energy pulse to the length of the day. This level was maintained the rest of the day with slight fluctuations.

Thursday tremor signal recorded by the seismic monitoring network stations maintained the level of the previous day, detecting some small pulses of short duration and light fluctuations.

Although the signal has low levels of amplitude, the tremor is still present in the record confirming the continuity of the eruption.

On the other hand, in terms of seismic activity in El Hierro, on Thursday and Friday the IGN recorded a total of 6 events of low magnitude, although none of them was felt by the population. On Friday were three movements at a depth of between 16 and 20 kilometers, two of which were also located in the Gulf, one sea area and one on land, and the third in land west of the municipality of El Pinar.

On Thursday there were three events at a depth of between 14 and 16 kilometers, two of them located in the area of El Julan, 1.4 and 1.5 magnitudes, and another near La Restinga, which reached 2.3 degrees of magnitude.

11.949 Events were located in total since July 19.

Deformation

The deformation monitoring stations yesterday in the Gulf stations showed a slight tendency towards the North in the horizontal components. In the rest of the island and the vertical components was observed a stable pattern.

El Hierro.com

The island of El Hierro is situated in the most southwestern extreme of the Canaries at 27.7º north and 18.0º west, and is the smallest of the archipelago at 278.5 km2.

El Hierro was designated by UNESCO as a Biosphere Reserve in the year 2000, with 60% of its territory protected to preserve its natural and cultural diversity.

It's no wonder that the smallest Canary Island delights all who visit, not only for its great natural and ecological attractions, but also for the contribution of its inhabitants in the sustainable development and conservation of the natural and hereditary wealth of the area.
The origins of the island date back some 100 million years when the ocean floor shifted with the movement of the earth's mantle. The crust consequently cracked into a three pointed star releasing flows of magma.

After three successive eruptions, and consequent accumulations, the island emerged from the ocean as an imposing triangular pyramid crowned by a volcano more than 2,000 metres high.

The initial crevices became channels for further lava flows which grew into three mountain ridges topped by numerous volcanic cones. While the magma cooled in these channels, it solidified into gigantic vertical basalt dykes, typical of the geological architecture of El Hierro.

The volcanic activity, principally at the convergence of the three ridges, resulted in the continual expansion of the island. A mere 50,000 years ago, as a result of seismic tremors which produced massive landslides, a giant piece of the island cracked off, crashed down into the ocean and scattered along the seabed.

This landslide of more than 300km3 gave rise to the impressive amphitheatre of the El Golfo valley and at the same time caused a tsunami that most likely rose over 100 metres high and probably reached as far as the American coast.

Although over 200 years have elapsed since the last eruption, El Hierro has the largest number of volcanoes in the Canaries with over 500 open sky cones, another 300 covered by the most recent outflows, and some 70 caves and volcanic galleries, notably the Don Justo cave whose collection of channels
