Update 08/01 – 09:49 UTC
- Very few burning gas during the night although it would have been a totally different view with a light sensitive webcam. In developing the screen-shots we saw a lot of different color intensities.
- We are anxious to watch the satellite or helicopter images later today as we see a very wide and concentrated stain
- The comments this morning are again talking about the steaming process. As can be seen on the colorful images from Involcan below, we are still talking about long steaming/smoking lava blocks, not a strong steaming portion of the water. We do not think that this will happen as we expect in the next phase to see strong vertical steam jets getting to the surface, very limited in the beginning and gradually increasing.
- Harmonic Tremor is back to the values from yesterday, after having decreased to the minimum after midnight.
- Many people are talking this morning about the many seagulls they are seeing above the active vent. If you look at images from the first jacuzzi’s, you will see the same phenomenon. Why ? We truly do not know. It mzay be bait they find there as it is being killed by the volcano, but nobody has reported this yet or they may like the higher temperature of the water

Update 07/01 – 23:59 UTC
Lets finish this extraordinary day with the (once again) superb images which have been taken by the Guardia Civil helicopteres and Involcan. We are also sure that scientists will have a very huge task in analyzing what exactly is happening here. Hot SLS who are coloring the water leaving traces of different components. Mother nature in its complexity but also in her impressive beauty. Even after following the process since many months we are still speechless in what we sometimes see.


Update 07/01 – 22:51 UTC
What you will see on this very short video is burning lava. We have more footage, but fainter short blue lights. We have zoomed the area a little bit and have slowed down the speed with a factor 2. Thanks to all our readers who have seen the (limited) action (so far).

The INVOLCAN slightly higher thermal anomalies recorded in the waters affected by submarine eruption of El Hierro

Measurements were made on Saturday January 7 using thermal imaging cameras through the support and cooperation of the Service Civil Guard helicopters Zone Canary

Scientists at the Institute of Technology and Renewable Energies (ITER), an agency of the Cabildo of Tenerife, and is now part of volcanological Institute of the Canaries (INVOLCAN) have informed the management of the Civil Protection Special Plan for Volcanic Risk Canary Islands (PEVOLCA) over the registration of thermal anomalies on Saturday January 7 in the surface environment of marine waters affected by the submarine eruption of El Hierro slightly higher than those observed during the month of December 2011. Measures the difference between maximum and minimum temperatures reflected in the surface environment of marine waters affected by the eruption of La Restinga submarine were performed by using thermal imaging cameras in air mobile position by the support and collaboration of the Unit Civil Guard helicopters Zone Canary Islands. On this flight scientist participated Saturday January 7 Kenji Nogami, Professor of Tokyo Institute of Technology (Japan), the top science advisers on Japanese submarine volcanic eruptions and scientific collaborator of the INVOLCAN.

The difference between the maximum and minimum temperatures reflected in the waters became 4.9 C on Saturday, January 7, 2012. The range of values ​​observed for this temperature difference has been reflected 1.5 C to 9.1 C, but this difference did not exceed 3.0 C in the records made by scientists from INVOLCAN flight to the Helicopter Unit of the Guardia Civil Canary in the area during the month of December 2011. During the same on Saturday January 7 also observed the presence of lava balls or balloons large (some> 2 meters) that amounted to the sea surface and floated through volcanic gas trapped inside coming to register reflected temperatures associated with these balls or globes washed on the order of 85.5 C.

In the INVOLCAN youtube channel (http://www.youtube.com/user/INVOLCAN/videos) shows the videos on the flight and INVOLCAN scientist Helicopter Unit of the Guardia Civil in the Canary Islands on Saturday, 7 of in January 2011.

Since mid October 2011 the highest values ​​observed between the maximum and minimum temperatures were 8.3 reflected C, 6.8 C and 9.1 C recorded on days 6, 7 and 8 November 2011. These temperature anomalies were recorded prior to the intense bubbling observed on 8 November 2011elevando water, gas and ash that reached suspended several meters above the water surface. These temperature differences reflected in the surface environment of marine waters affected by the eruption underwater clearly reflect a significant heat flow as a result of eruptive activity, and allows it to be an additional tool for monitoring the evolution of the eruptive process in southern La Restinga.
The temperature is a measure of reflected radiant heat from the surface of the object being measured and in this case, from the surface seawater. The record of this series was made possible by the support and collaboration of the Helicopter Service of the Guardia Civil, in the framework of a cooperation agreement between the INVOLCAN and the airline industry in the Canary Islands Civil Guard to strengthen the geophysical program (thermometry and thermography) that provides INVOLCAN for volcano monitoring in the Canary Islands and 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).

INVOLCAN 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.

Among the tasks of INVOLCAN, education and training on the phenomena related to Earth Sciences have an important weight. So today we wanted to share an interesting video that shows in perspective the magnitude of earthquakes, something that has always been confusing to the general public. For example, this morning in the archipelago has been an earthquake of 1.5 degrees. Need almost 1000 earthquakes of this magnitude to equal the energy released by the of 3.5 that occurred off the coast of Lanzarote a few days ago (factor 33 for each order of magnitude). This video shows us vividly the immensity of the great earthquakes that occur on our planet.

This animation compares the relative "sizes" of recent and historical earthquakes. Each circle's area indicates relative energy release, color indicates tsunami potential (see http://ptwc.weather.gov/ptwc/about_messages.php), and labels indicate each earthquake's moment magnitude (according to USGS/NEIC), location, and the year they happened.

The volcano of the las Calmas Sea continues to give low rates of sulfur dioxide

Scientists at the Institute of Technology and Renewable Energies (ITER), an agency of the Cabildo Insular de Tenerife , part of volcanological Institute of the Canary Islands (INVOLCAN) have informed the direction of the Civil Protection Special Plan for Volcanic Risk in the Autonomous Community de Canarias (Pevolca) the submarine eruption of the volcano of the Sea of Calm in El Hierro , continues to record low rates of emission of sulfur dioxide (SO2) into the atmosphere.
The monitoring and measurement of SO2 into the atmosphere by the eruption underwater south of La Restinga reached a peak of 109 19 tons per day last November 6, 2011. This maximum value was recorded prior to the intense bubbling observed last November 8, 2011 High water, gas and ash that reached suspended several meters above the water surface. Since then, the sulfur dioxide emission has experienced a decline in their values, and currently is near the detection limit of the analytical methodology used (~ two tons per day). These results reflect an SO2 emission rate relatively low to those normally recorded in subaerial volcanic systems, which are eruptive phase, because most of the discharge of sulfur dioxide by underwater eruption south of La Restinga is trapped in the seawater as a result of a neutralization reaction between volcanic gases and acid-alkaline nature of water causes a marked decrease in seawater pH as currently reflected by measurements taken by research vessels "Professor Ignacio Lozano 'and' Ramon Margalef 'Canary Institute of Marine Sciences (ICCM) and the Spanish Institute of Oceanography (IEO), respectively.

Over het waarom de vulkanologen niete alle data puliek (kunnen) maken.
quote:
Update 09/01 20:49 UTC
Comment by Dr. Boris Bencke, volcanologist at the Osservatorio Etneo, INGV- Catania, Sicily, Italy.
Dr Bencke is commenting on our 23:30 update from yesterday.
---------------
Just to correct a bit of information in the 8 January 2012 23:30 h update where it is said that the Spanish volcanologists received aid from Sicilian volcanologists. This has unfortunately not happened yet. One of my colleagues in the INGV Catania has been asked a few months ago to maybe go to El Hierro, in case the eruption would be shallow-water Surtseyan. So far the eruption has not reached that stage, and so far my colleague has not gone to El Hierro.
Again, to respond regarding the slowness of diffusing scientific data recorded on the eruption to the broad public this is not as easy as it might seem to people outside the scientific circuits, because a lot of the data needs first to go through a lot of processing and then a part is obtained with costly methods covered by funding that requires interim reporting, and a lot of data will be kept secret until published in scientific journals. Communication with the public is becoming more and more fundamental and many scientists feel the need to expand into that direction, including myself, but it means a lot of extra work without getting paid extra, and even when idealism is high, everyday work demands often hamper any efforts to go far beyond. Very often it is not that scientists do not will to share information with the public (of course, keeping the good bits to be used for scientific publications which are essential for a scientist to get, or keep, a job). Its simply that they have to respond, in a crisis situation, to a vast amount of agencies and people, including Civil Defense, administrations, and like at Etna aviation authorities, and so on.

- Everything look so quiet today. An steady eruption : harmonic tremor pattern and no further earthquakes.
- The Japanese specialist from the Tokyo Technological Institute, Kenji Nogami, specialized in submarine eruptions is presently helping the Involcan scientists analyzing the data. He said about the same things that we have mentioned earlier on, like :
* the eruption can last from a couple of hours up to 2 years
* that the danger for the population is relatively limited as the current vent is more than 1 km out of the coast
* that in case of a Surtseyan phase, water columns of 20 meter may be expected and that clouds of steam and ash may rise up to 400 meters
* that fallout of ash has a radius of 1 km (ER : normally the wind blows to the south, so there will be little annoyance for La Restinga)
All this based on the current vent and eruption pattern.

Update 11/01 – 22:57 UTC
- A 7th earthquake occurred tonight at 19:03. It had a magnitude of 1.5 with a focal depth of 11 km. Epicenter was west of El Pinar.
- Harmonic tremor seems to get some spasms late tonight. The mostly hydromagmatic action can start a new set of humeantes (lava balloons) but at the same time can trigger a new collapse of the vent.
- Those people who are able to look at the webcam after midnight UTC (if the live in another time zone), may take a look from time to time at the webcam and inform us when they see something special.

The INVOLCAN continues to record a decrease in the diffuse emission of CO2 by the volcano island of El Hierro

This downward trend since late November until now reaching 664 24 tonnes per day

Scientists at the Institute of Technology and Renewable Energies (ITER), an agency of the Cabildo of Tenerife, and is now part of volcanological Institute of the Canaries (INVOLCAN) have reported to management of the Civil Protection Special Plan for Volcanic Risk Canary Islands (PEVOLCA) that continue to show a downward trend in the diffuse emission of carbon dioxide (CO2) into the atmosphere by the volcano island of El Hierro since late November, when it came to achieving the 2398 115 tons per day until today, when it has been recorded an emission rate of 664 24 tonnes per day. To clarify that these emission rates do not refer to the emission of carbon dioxide (CO2) that occurs through the underwater eruption of El Hierro, but the amount of carbon dioxide (CO2) emitted to the atmosphere through the surface environment (soil-air interface) that makes up the 278 km2 area of ​​the Island Meridian.

To obtain these results are carried out scientific surveys, involving hundreds of diffuse flux measurements of carbon dioxide (CO2) distributed across the surface of the island of El Hierro, in order to investigate the spatiotemporal variations of the diffuse emission of carbon dioxide (CO2) into the atmosphere by the volcano island of El Hierro. The interest and importance of this work on diffuse emission of carbon dioxide (CO2) for volcanic surveillance because the information generated through these scientific surveys can not be obtained through permanent instrumental networks.

Other scientific reasons that support the interest of these works are monitoring the role of gas as the driving force of volcanic eruptions that carbon dioxide (CO2) is the second major component of volcanic gases after steam water, and the low solubility of carbon dioxide (CO2) in molten silicitados (magma) favoring their escape with 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.

INVOLCAN 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.

Temporal evolution of the diffuse emission of carbon dioxide (CO2) in the island of El Hierro (red circles) recorded by the INVOLCAN and the daily number of earthquakes located above magnitude 1.7 by the National Seismic Network (IGN).


quote:
In the evolution of the depth of earthquakes in El Hierro from the October 1, 2011, you can see the end of the first swarm and shallow earthquakes that preceded the opening of the eruptive point in the Restinga area, then go the second swarm from late October to early December and then stops.

The truth is that once you finish the second swarm from mid-December seismicity can be seen in the canal ... but this seismicity appears to have a tendency to decrease its depth, but it is too early for any interpretation or meaning of this graph.

Earthquakes is also more superficial dispersion of efforts. and as the efforts are increasing. Although there are few data, one of the hypotheses that I can think to explain these data is the possibility that the magma conduit in its flow, slowly progressing to shallower levels, so you have to follow the evolution of this graphic to verify this fact or deny it.

En een berichtje van gister op Earthquake report
quote:
Update 14/01 – 17:16 UTC
- Based on the current and past position of the Ramon Margalef (gradually and slowly getting closer to the jacuzzi) we suppose that the Oceanographip ship is using one of his ROV‘s to have a close look to what is happening beneath the surface. The ROV’s are able to navigate to deep depths and are manipulated out of a control room on board of the ship. Depending on the visibility, which may be good out of the current, we might be able to look at great video one of the coming days. If the ship isn’t using his rov’s ha may be taking samples of the different waters newt to the vent. Both possibilities are realistic.
Plaatje is wel een beetje klein - nog geen betere kunnen vinden

- Finally 1 earthquake today, a M 1.4 earthquake at a depth of 19 km which happened at 22:43 UTC
- Around 10:00 harmonic tremor has started to rise gradually being at his strongest in the late evening hours.
- Hydromagmatic bursts can well be seen on the HT graph
- During the evening hours, the Jacuzzi was very well visible
- Yesterday was the inauguration of the RINSTINGOLITA INFO CENTER in La Restinga. All important people who were part of the emergency and follow-up actions on the volcano were present. The Info Center shows a lot of pictures and material from IGN, CSIC, IEO and INVOLCAN. Joke made some pictures during the opening.
