Just a guess, magma may have entered the system here:

Hi Karenz,
 Interestink, verrry interestink...
I propose that; all along magma has been coming up via El Golfo, filling the reservior under Tanganasoga, and once a "head" has built up, that it releases upwards/southwards via Bob and the BoBettes... just lately B n' the B'ettes have slowed down, and now most of the action is via the fissure on the plateau above Bob... This seems to be consistent with earlier patterns...I predict an Surtseyen-type event before this is over...

Don't know.

An alternative theory is that magma is rising under Tanganasoga. The activity to the North & South appears to be dyke instrusions and / or rifting.

Hi Vicente Luis Perez. First it is only a hypothesis and not a certainty and that hypothesis is based on the premise of the growth of the volcano without, as say the authorities by reporting them scientists, there is no evidence of eruption. If you have seen screenshots of eruptions in Hawaii can be an idea of what is an effusive eruption because they are of this kind, and are characterized by the type of magma (basic magmas) that comes to the surface with ease and without just cause explosions and releasing the gases very easily. This type of eruption does not have why cause a tremor signal accused in sensors (in fact there is documentation about effusive eruptions at Mount Etna which showed no signs of tremor). But, as I said, all this are nothing more than just hypothesis seeking a possible explanation to the growth that has occurred in the height of the volcano and so far has not been properly explained by scientists stationed at the island nor documented as comes asking for some time, with the dispatch of an underwater robot that can capture images.(Nino)

Nino, the Tanganasoga or tanganosaga according to others, is a stratum volcano mature and unfinished, and in its central structure there is apparently a vertical driving which is a few hundred meters, even some kilometres, which represents the greatest danger to my modest understand for the island of El Hierro, of all volcanic edifices of the island. On this volcano, to their predictable deeper pipelines have been most of the seismic events that have occurred under the island building between 24 up and 10 kms. depth, always according to the official data of the IGN. Why, and just for that, I deserve the greatest respect and I admit openly, deeper fears the existence of this natural Monster think someday grew up in El Hierro but did not burst, as if it were a giant grain at the foot of central Rift. I have no more data than vostros but yes much intuition, and in some occasions usually hit.

Why put as an example what we have seen in the documentary of the Pinatubo. Nothing is worth that think people, as much as we want or pray nature is relentless and unstoppable. If quakes in the origin back in the month of July 2011 pointed to a possible scenario at the Centre of the island, in the area of the Gulf, between border and Sabinosa, while an underwater eruption (fisural memory) has occurred in the South, in a asísmica way and almost without being more than provided for in statistics (90% of the submerged building - 10% on the sea) that surely helped lighten the pressure of throughout the system, at the end, the capricious and stubborn nature despite our wills and efforts will eventually manifest itself as I thought. That is what I think and pray to God I'm wrong completely to avoid greater evils to our countrymen Islanders. (Translated by Bing)

I ask an effort of imagination. Close your eyes and imagine a pen mantélica shaped crest of gallo, based very deep beneath the island building of El Hierro and oriented towards north northeast-southwest South, more less through the center of the Valley of the Gulf in La Frontera. At the same time, the tip of the Ridge further to the South, is branching on the submarine rift and goes looking for place by where out and finally found a place South of La Restinga, after traveling in direction Northwest – Southeast deeply mar de las Calmas following an increasingly crystallized through finally ends up become saturated and ceases unless the mass exit of materials, not of gases by some of the multiple mouths of a underwater eruptive fissure. Now are the Central ridges which struggle to find the exit, following fractures in the center of the island building, melting materials and moving very slowly but inexorable way in its rise toward the surface. If you ask me which I believe to be the most broken part of the island where you can climb the magma, I think in the Centre of the island, just where originated this tremendous strata volcano in the images that you can see in the following link:

The INVOLCAN reflects that the emission of CO2 by the island volcanic edifice of El Hierro is 934 tonnes per day


Since the end of January recorded an emission of carbon dioxide (CO2 quasi-constant and superior to the 800 ton diariass)


Scientists from the Institute of technology and for renewable energies (ITER), agency under the Cabildo Insular de Tenerife, and currently part of the Instituto Volcanológico de Canarias (INVOLCAN) have communicated to the direction of the Special Plan of Civil protection by risk volcanic of the community autonomous of Canarias (PEVOLCA) that since will begin the process of volcanic reactivation in El Hierro the INVOLCAN has taken 23.961 measures of diffuse flux of carbon dioxide (CO2) on the surface island of El Hierro (approximately 100 measures daily), and that the most recent data reflect that the rate of diffuse emission of carbon dioxide (CO2) into the atmosphere by the island volcanic edifice of El Hierro is 934 ± 29 tonnes per day. Note that this value does not refer to the broadcast from the underwater eruption of El Hierro, but to the amount of carbon dioxide (CO2) which airs recently into the atmosphere through the entire surface Island (278 Km2) of the island of the Meridian.


From the January 22, 2012, the rate of diffuse emission of carbon dioxide (CO2) into the atmosphere by the island volcanic edifice of El Hierro has experienced a slight increase (878 tons per day average) respect values registered on December 20, 2011 to January 21, 2012 (average of 706 tonnes per day). Considered normal values for the iron range range approximately from the 142 to the 866 tonnes per day with an average value of 345 tonnes per day. To obtain these results are carried out periodic scientific campaigns, involving hundreds of measures of diffuse flux of carbon dioxide (CO2) made on the surface of the island of El Hierro in each of the campaigns, with the aim of investigating variations spatio-temporal of the diffuse emission of carbon dioxide (CO2) into the atmosphere by the volcanic edifice island of El Hierro.


The interest and importance of this work on diffuse emission of carbon dioxide (CO2 for volcanic monitoring) are due to that the information generated through these scientific campaigns cannot be obtained through permanent instrumental networks. Other scientific reasons that guarantee the interest of these monitoring work are the role of gases as driving force of volcanic eruptions, know that the carbon dioxide (CO2) is the second major component of volcanic gases, after water vapor, and have knowledge that the low solubility of carbon dioxide in molten (magma) silicitados favors the escape of carbon dioxide (CO2) with great ease of volcanic systems in depth.


These scientific campaigns have been able to realize thanks to the project MAKAVOL "Strengthening of the capabilities of I+D+i+d to contribute to reducing volcanic risk in the Macaronesia (MAC/3/C161)" is being co-funded by the programme for transnational cooperation of the European Union Madeira-Canarias - Azores (MAC 2007-2013) and the collaboration of the island Cabildos of Tenerife and El Hierro.


INVOLCAN is an institution demanded unanimously by the Senate (2005), Parliament of the Canary Islands (2006) and Congress (2009) with the aim of contributing to the improvement and optimization of the management of the volcanic risk in Spain.

Involcan detects a ´reactivación volcánica´ in El Hierro

"ACNPRESS scientists from the Institute of technology and for renewable energies (ITER), body dependent on the Cabildo Insular de Tenerife, and currently part of the Instituto Volcanológico de Canarias (Involcán) had been informed by the direction of the Special Plan of Civil protection by risk volcanic of the Canary (Pevolca) than from the January 22, 2012, the rate of diffuse emission of carbon dioxide (CO2) into the atmosphere by the volcanic edifice island of El Hierro""has experienced a slight increase", with an average of 878 tonnes per day, with respect to the values registered on December 20, 2011 to January 21, 2012, whose average was 706 tonnes per day.


"The latest data reflect that the rate of diffuse emission of carbon dioxide into the atmosphere by the island volcanic edifice of El Hierro is 934 ± 29 tonnes per day, value that does not refer to the broadcast from the underwater eruption of El Hierro, but to the amount of CO2 emitted into the atmosphere through the entire surface Island (278 Km2) of the Meridian island"they say in a statement.


VOLCANIC REACTIVATION


These results are "consistent with the current process of volcanic revival which is registering the iron", as well as concluded during the last meeting of the Scientific Committee, resulting in the direction of the Pevolca keep the situation of the volcanic light yellow for the island.


"It should be noted that referrals values do not represent any danger for the population or for terrestrial island ecosystems, given that this issue not is this recording through of a single point of emission, but through the entire insular surface", say.


The range of emission considered normal for El Hierro goes approximately from the 142 to the 866 tonnes per day with an average value of 345 tonnes per day.


To obtain these results are carried out periodic scientific campaigns, involving hundreds of diffuse flux of CO2 measures carried out on the surface of the island of El Hierro in each of the campaigns, in order to investigate spatio-temporal of the broadcast variations.

In the map of the simicidad of recent days, today an earthquake in the Gulf and one in the southeast of the island, area that had no seismicity long. The fact is that the earthquake today in the Gulf and the 5 sismitos of yesterday are aligned NNE - SSW from the Gulf to the mar de las Calmas, passing by the area summits and the Julan. Antesdeyer a sismito in the Gulf and one in the Julan to the S.

Hello Isilda, means that in the spectrogram notice several earthquakes detected, yesterday more than 20 and only have been localized 3 by IGN and now goes by the same camin, but the past day 09 there was a swarm microsismico with a lot mircrosismidad, they are considerably more than 20 earthquakes per hour, with more than 100 throughout the day, but located.... 3 and these at this time.... None... (Henry)

Update 15/03 – 22:31 UTC
 -  AVCAN reports that the Atlantic Explorer ROV Wally has fairly good images of the crater, gas emitting vents and even lava streaming out of the crater ! (what would e really a surprise as the PEVOLCA scientists have claimed that the eruption has ended.

Pevolca seem to have been incorrect in saying the erruption has eneded because the results of the ROV pictures are showing lava streaming from the crater and the vents are emitting gases.

Its a pity that the pictures are not as yest being shown to the public.

Avcan FB Comment Copied and translated from the link below.

Scientists from the University of Las Palmas de Gran Canaria, aboard the research vessel chartered by the University to conduct campaigns in the area of the calm sea (El Hierro), have been able to shoot through a submarine robot of the Atlantic Explorer ship submarine volcano Cone and it has been the first camera that sits in the cone of the volcano.


Scientists point out that there is no tremor on the surface of the water, but yes is can appreciate a "rain of incandescent stars" at the mouth of the volcano and volcanic focus continues active, where had taken samples of more than 60 degrees water temperature. In the area also have seen that the marine life has returned to appear in the vicinity of the volcano.


The campaign, called GUAYOTA 2-ULPGC, have involved researchers of the GEOVOL (Group of geology of volcanic terrain), Division of Robotics and computational Oceanography (IUSIANI - University Institute of intelligent systems and numerical applications in engineering) and the IOCAG (University Institute of Oceanography and Global change) - all the ULPGC - and therein work Institute Jaume Almera (CSIC) and Centro Oceanográfico de Canarias (IEO).







The campaign unfolds aboard B/O Atlantic Explorer (QSTAR S.L.U.) for the study of the submarine volcano of iron and their Oceanographic affectation, as well as observing and filming of the volcanic cone.


The first results of the images that have been recorded are:


-For the first time have obtained images of the new submarine volcano emerged near La Restinga (El Hierro), on its Southwest flank and in area close to the crater (to 172 m)


-In both missions found that the main volcanic focus remains currently active


-Emerging from depths of about 120 m, shows the formation of hot jets convective which reach depths of about 40-60 m. At the start of Tuesday 13, the ROV entered one of them and made several uncontrolled turns, while its sensor of temperature increased sharply


-Also, projections about 40-50 m tall pyroclastic are generated from these same depths (i.e. the pyroclastic reach depths of 80-70 m), they quickly form (parabolic) ballistics trajectories and fall by gravity. Some of these pyroclastic appear to be large (type volcanic bombs)


-In the immersion of Wednesday 14 was filming the Southwest flank of the main Cone, making clear that has a steep slope and consists, essentially, of pyroclastic of large size, some of which are similar to the hollow volcanic bombs which reached the surface in the months of November and December


-Finally, in the vicinity of the flank, at a depth of approximately 170 m and under a rain of ashes, had a Bank of fish (amberjacks possibly) coexisting with the volcano. Also, confused with the ashes there is multitude of small organisms and longer, closer to the surface, jellyfish.



The University of Las Palmas de Gran Canaria chartered a ship to facilitate the conduct of scientific research in the sea of la Restinga (El Hierro), in the area where the submarine volcano.


The Vice President for research, development and innovation of the ULPGC, directed by Fernando Real, has coordinated the rental of the Atlantic Explorer ship the QStar company, will take place 7 campaigns of research in three months and a half, as of February 17. The research will be carried out by the scientists of the departments of biology, chemistry and physics, the university institutes of Oceanography and change Global (IOCAG), of numerical applications in engineering (SIANI) and of Animal Health (IUSA), the Spanish bank of algae and biological oceanography, physical research groups and by satellite, marine chemistry, robotics and intelligent systemsMarine ecology and fisheries and geology, among others.
