Data Update 23/11 - 23:48 UTC
- 20 earthquakes M 1.5 or more today
- depths from 10 km (21:12) to 25 km
- harmonic tremor can be called medium + a couple of bursts

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 !

Images of November 23 2011 made by Joke Volta and Ian Carson

Update 23/11 - 20:39 - La Restinga Webcam saga (continued)
Joke Volta was so kind to take this picture on our request. It shows the location of the 3 webcams. It does not help us a lot, but at least we know now where they are installed.

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.

Update 23/11 - 16:56
First series of images have been uploaded in our Picasa account. The present images are all from Joke Volta. Ian Carson is still at different viewpoints. He only returns to a wifi location in the evening.

Update 23/11 - 13:48
- 2 readers Hans-Werner and Kasper + we guess a lot of others have seen the Guardia Civil helicopter above the stain.  This will deliver us hopefully beautiful pictures later today.
- at 11:22 , a 2.6 magnitude earthquake occurred at a depth of 13.3 km approx. 2 km to the south of Puerto Naos
- Joke reports that the local press is "absent" today. NO video on the Canary Island television.

Update 23/11 - 13:35
- Reader Martin Rey made an attempt to map the vents in relation top the La Restinga harbour.

Update 23/11 - 11:07 - Birth of a new vent !
A lot of activity this morning in the Las Calmas sea just south of La Restinga. New vents are opening and we could record the image of the webcam and then speed it up. It allows us to see the start of a new vent.

Update 23/11 - 11:07
- Based on the webcam views, it is clear that many vents are emitting magmatic material at the moment. The bird's Eye View from the Guardia Civil helicopter will surely proof that later on.
- Also based on the webcam, it looks that the vents are closer to La Restinga but this is hard to say as we do not know the zoom aspect of the webcam.

Update 23/11 - 10:57
- Joke is currently moving to a wifi cafe in La Restinga to send us the first stain pictures of the day. The coloring as seen on the webcam this morning will be probably very beautiful from Montaña Naos (Naos Mountain viewpoint). Ian does not want to miss one second from the beautiful activity and continues to make images from the Naos mountain viewpoint.
- Joke has to move her belongings to another house but she is so excited about what is happening that she decided to cover today's events first.

Update 23/11 - 10:11
- Joke has just reported that what they see from the mountain is quiet spectacular. She met Ian Carson a little while ago and both are shooting pictures of the activity, which we will publish when they have the opportunity to upload them.

Data update 23/11 - 08:46
- Joke Volta told me a little while ago that the stain is clearly visible from El Pinar this morning
- IGN has listed 7 M+1.5 earthquakes since midnight UTC
- The depth varied from 15 to 20 km. We notice more earthquakes at a depth of 15 to 17 km. Nothing to implicate direct danger.
- Yesterday, the day ended with 35 earthquakes, 2 being stronger than M 3
- Harmonic tremor at medium strength with more occasional strong bursts
- Air Quality at La Restinga : no unusual values
- weather outlook : 15 - 17 knots winds and wave height 2.5 meter max. Partly cloudy.

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.

Data update 22/11 - 23:50
- Stronger Harmonic tremor in between 19:00 and 20:00
- 28 earthquakes M 1.5 or since midnight
- 2 Earthquakes measuring 3.3 - The 16:43 earthquake was felt by the islanders
- Depth hypocenters : 12 to 23 km

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....
The beauty of this island continues to unfold. If there is a God, he should spare this beautiful island and wonderful people from the power that nature can unfold

Click here for the entire image series Ian made today - Of course of the activity, but also one from the north + we have also added a picture from Joke and Ian, who have met each other in El Pinar in the meantime.

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, a helicopter arrived also above the stain but unfortunately when most of the activity had subsided.

Multiple vents can be seen on Ian Carson images from this afternoon - Click on the image to go to the bigger pictures

Update 22/11 - 17:49
We have made a 6 seconds video from a few minutes eruptive action of the vent. Click here to watch the YouTube video.

Update 22/11 - 17:13
- IGN reports a magnitude 3.3 earthquake at a depth of 22 km in the El Golfo bay.

Update 22/11 - 16:10
New Jacuzzi and ejecting magmatic material (sometimes) visible on the Telefonica Eruption webcam at 16:10 UTC. We advise you to watch the webcam at least for 10 to 15 minutes. Please keep in mind that the distance from the present activity vent to the port of La Restinga is a approx. 3 km. Update 16:55 UTC : The good views only lasted for about 10 minutes.  To much backlight on the webcam at the moment. We expect better views within an hour

Update 22/11 - 15:26 - Proof of New degassing Vent yesterday (see also Ian Carson earlier comments)
Those people who have read the words of Ian Carson yesterday must have been surprised to read later on the IGN dismissed these findings and said "NO new vent" was found.
The Helicopter Unit of the Guardia Civil and Involcan detected a sudden release of gas south of the Restinga. The sudden release of volcanic gases were recorded at 11:40 hours on Monday November 21. Scientists of Involcan have informed PEVOLCA of the detection of a new sudden release of volcanic gases at 11:40 on Monday November 21. This visible emission of volcanic gases was located about 200 meters to the east of the main emission zone active from mid-October 2011. After the detection of the new vent by the Helicopter of the Guardia Civil, Involcan scientists returned to the new degassing vents to do some additional research (ie thermal imaging, etc) and had to find out that the intensity of the fumes disappeared, as it did during some previous occasions (November 4, 2011). These observations confirm the existence of sudden pulses of gas by submarine eruptive activity south of the Restinga. The geographic coordinates of this new sudden release of gases has been North 27º607547 / -17º991288  West.

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.

Update 22/11 - 09:25
Yesterday, the Canary Island geologist

Ever since the submarine eruption occurred on October 10th, everyone seemed to think that the crisis would end in a few days. But it did not. There have been 40 days of eruption and we do not know when this will end. In the north of the island in El Golfo, a new seismic crisis began with deeper hypocenters and somewhat higher magnitudes. Also the direction of the new fissure is different: it is pointing directly at La Restinga. If it progresses on land, the danger increases and with it the risk.
The risk is not just whether there will be an eruption or not. The status of the Los Roquillos tunnel is worrysome. On October 18, technicians examined it and found many deficiencies caused by the earthquakes: cracks in several stretches, cables with anchors detached, loosening of the keystones, in other words, the current status is disastrous. With the pressure from the people, who would now dare to say it is dangerous to travel through it while the earthquakes are continuing some with magnitude 4.0?

Data update 22/11 - 09:18
- More seismic activity today
- Harmonic tremor subsided since yesterday 03:00 and has stabilized with occasional ups and downs since yesterday 18:00 UTC
- The increased number of earthquakes are (so far) related to the subsided harmonic tremor. We expect the earthquakes to become gradually stronger again until we will have a new strong eruptive period. The buildup can last from a couple of hours to a couple of days.
- 12 earthquakes M 1.5 or since midnight
- Earthquakes are M 2.1 or less
- Depth hypocenters : 12 to 23 km
- The epicenter of the shallowest earthquake (one of the shallowest in the El Golfo area since many weeks) was almost below Los Llanillos. If there would be more of these, it will have to be seen as a major new step in the activity (no immediate danger but it will need careful examination)
- the sea is too wild to see any stains or Jacuzzis this morning
- - Weather forecast for today : the wind will be blowing from the North-East (current to the west). Max. wave height 2.0 meter. Sunny most of the day.
- more weather prognosis at the El Hierro page of Windfinder.com

Update 22/11 - 09:10 - La Restinga Webcam saga (continued)
We are very sorry that we have to write continuously about the webcams, but the authorities have not yet learned how to use the webcams properly. At the one hand they are proud that the world is looking to them, but on the other hand they do not take care and they don't keep their promises.
- One of the biggest complaints of the La Restinga Eruption webcam is that is is constantly moved
- When there is a reference, like the port wall, one can see clearly like this morning, that the focus is completely away from the stain and eruption vent.
- The promise of the 2 webcams that Telefonica and the Cabildo should install in the north (El Golfo area) is not kept

Data update 21/11 - 23:00
- 16 earthquakes M 1.5 or greater today
- strongest earthquake : M 3.3 @ 21 km depth in the El Golfo area
- Depth hypocenters : 15 to 23 km
- 1 earthquake was felt by the people of El Hierro
- weak Jacuzzi activity was noticed this morning and was seen at intervals on the Telefonica Eruption webcam
- a greenish stain was noticed from higher parts of the island

Update 21/11 - 21:13
- At 18:02 tonight a 3.3 magnitude earthquake struck at a depth of 21 km in the El Golfo area, the location where almost all the earthquakes are occurring.
- another earthquake attracted our attention. The M 2.4 earthquake at a depth of 15 km with an epicenter below the coast of Puerto Naos.

Important Update 21/11 - 18:06
In a twitter message tonight, PEVOLCA and IGN have dismissed that todays activity would be a new vent. IGN and GES scientists made a flight this evening by helicopter.  The information from Ian Carson came from the helicopter flight of the Guardia Civil which took off when the activity was at his strongest, which cannot be said from the IGN / GES flight !

Update 21/11 - 18:06
Some vent activity could be seen tonight on the Telefonica / Cabildo  La Restinga eruption webcam. Since we still do not have HD-webcams, the image is not sharp, but the activity (left lower part of the screen). We have compressed 15 minutes of footage into 1 minute 47 seconds.

Important update 21/11 - 16:40
Ian Carson reports :
I went to Restinga for 0830, everything was quiet and the tremor intensity looked to be decreasing (on my phone) so I caught the bus at 10.30 to return to El pinar. On leaving Restinga and beginning the 900 m climb to Pinar, it was clear that something was stirring on the sea. The locals were all aware of it. I summoned the driver to stop (immediately) as I had been waiting for 3 days for any evidence of activity. Luckily, I was at the closest point to the activity, probably 1.5km nearer than the webcam. The 'Jacuzzi' was clearly evident as it was cloudy thus eliminating the normal blue reflection of the sky and increasing the contrast of the 'Jacuzzi'. In a short time, the Civil guard helicopter was in the air with geologists aboard. One of whom I was later to have a long discussion, he spoke good English and freely gave his time. The friendliness of the Canarian people has been a memorable part of this trip. I must also thank the 'Cafe Melao' who freely allow me to use their wifi after purchasing the occasional cup of coffee.

Pevolca press report Monday, November 21, 2011 17:56
Most important elements translated by Earthquake-Report.com
The scientists who are part of PEVOLCA are maintaining the forecast that, taking into account "the analysis of the seismic catalog of the latest twenty days, earthquakes with a maximum magnitude of 4.6 can be expected on the island.
Changes in the tremor signal can be the result of a collapse of the vent of the volcano or a change in the emission rate.
The number of earthquakes has decreased in recent days, as well as their frequency.
Scientists confirm that seismicity occurs in the same alignment NNW SSE, but always at a depth of 15 to 27 kilometers. The evolution of the eruptive process, remains stable, but leaves open the scenario of a possible eruption in the north, although such an possibility is certainly not imminent. "
The deformation follows the same stable pattern of as in the previous days.
The GPS stations in the El Golfo area are showing a slight elevation, while the rest shows a slight sinking.
The tremor signal had a significant change last Thursday with a sharp decrease in intensity, to pick up again on Saturday. This phenomenon may be linked to the collapse of the volcano vent probably due to the decrease in the emission rate. These data have been confirmed by the research vessel 'Ramon Margalef' while making the next bathymetry.
PEVOLCA reiterates that the current alarm levels are maintained.

Original press report
Grupo científico mantiene máxima esperable en 4.6 grados
Lunes, 21 de Noviembre de 2011 17:56 -
El grupo de trabajo científico del PEVOLCA mantiene la previsión de una magnitud máxima esperable en la Isla de 4.6· Los cambios en la señal de tremor pueden estar asociados a un desmoronamiento de la pared del edificio volcánico o a un cambio en la tasa de emisión El grupo de trabajo científico del Plan de Protección Civil por Riesgo Volcánico (PEVOLCA) ha confirmado esta mañana que en El Hierro se mantiene una sismicidad con una magnitud máxima esperable de 4.6, teniendo en cuenta “el análisis del catálogo sísmico de los últimos veinte días”.
En todo caso, el número de sismos ha disminuido en los últimos días, así como su frecuencia, produciéndose un registro significativo en la madrugada del sábado al domingo “con un movimiento de magnitud 3.7”.
Los científicos confirman que la sismicidad se produce en la misma alineación NNW SSE, en el término de Frontera, pero siempre a una profundidad de entre 15 y 27 kilómetros. La evolución del proceso eruptivo, por tanto, “sigue estable, pero deja abierto el escenario de una posible erupción en el norte, que no tiene, en ningún caso, el carácter de inminente”.
En cuanto a la deformación, sigue el mismo patrón de estabilidad que en días anteriores en lo que respecta a los desplazamientos horizontales observados en las estaciones GPS.
Respecto a los desplazamientos en la vertical las estaciones GPS en El Golfo apuntan, mayoritariamente, hacia una ligera elevación, mientras que en el resto se observa un ligero hundimiento.
Por su parte, la señal de tremor experimentó un cambio significativo el pasado jueves, al disminuir su intensidad bruscamente, para recuperarse de nuevo el sábado. Este fenómeno podría estar asociado “a un desmoronamiento de la pared del edificio volcánico que se ha formado en La Restinga o a un cambio en la tasa de emisión”. Estos datos podrán ser confirmados por el Buque Oceanográfico ‘Ramón Margalef’ cuando realice la próxima
La Dirección del Plan Especial de Protección Civil y Atención de Emergencias por Riesgo Volcánico en la Comunidad Autónoma de Canarias (PEVOLCA) reitera que en la actual posición del semáforo volcánico en rojo para La Restinga
y en amarillo para el resto de la isla, la población de toda la isla ha de centrar su atención en los mensajes ofrecidos por las autoridades competentes a las que le asiste el Comité Científico.
Las administraciones públicas disponen de los dispositivos y medios necesarios para hacer frente a una modificación de la situación actual con la comunicación, en el momento adecuado, de instrucciones precisas para la población

Important update 21/11 - 15:09
Ian Carson did report the following a couple of hours ago  :
Just spoke to guy from Canaries Geological Institute  back from the Guardia Civil helicopter overflight. New vent today about 300 meters from old  (and the nearest) vent but parallel to and no nearer to coast than the old one. Quite a lot of bubbling at first but has settled to light blue stain as older vent.
- We expect Guardia Civil / Involcan helicopter images later today

Update 21/11 - 12:46 UTC
Contrary to what we said earlier on, a new stain might be forming. Ian Carson (see below) did report us a couple of hours ago that he saw signs of a faint Jacuzzi. The eruption Telefonica webcam did confirm Ian's words later on. Depending on the sunlight, the new stain can also be seen on the webcam. An additional sign of the present activity is the overflying Guardia Civil / Involcan helicopter. They are flying out when involcan can measure some emissions / water temperature etc.

Data Update 21/11 - 08:12 UTC
The El Hierro volcano may get tired as the pressure of the magma seems to subside. Too soon to say that the activity will be over, but the subsiding harmonic tremor and the decrease in strength and number of earthquakes are indicators that the strongest eruption period  may be over
- 5 M+1.5 earthquakes since midnight
- Strongest earthquake being a 2.6 at 02:02
- Depth of the earthquakes since midnight : 17 to 22 km
- Gradually subsiding harmonic tremor since 03:00 today
- air quality remains GOOD at La Restinga for volcano related emissions
- Weather forecast for today : the wind will be blowing from the North-East. Max. wave height 2.2 m vs 2.6 meter yesterday. Partially cloudy weather.
- more weather prognosis at the El Hierro page of Windfinder.com

Ian Carson writes from El Hierro
Went to Restinga this morning on same bus as Joke although we went our own ways. I continued my exploration of the old lava formations whilst keeping an eye on the sea. The oceanography ship was there most of the day (ER : Ramón Margalef), see Picasa series. It was difficult to see today as the sea was rough(ish) and the sun lower than ever with the approaching solstice. I would be surprised if the Webcams were performing well !
I spoke to a Spanish photographer (amateur I think) who I had seen before. He was showing his pictures of the former Jacuzzi when it issued material. They were quite impressive. He is shown in photos showing anyone who wants to see them, in the close up you can even see the 'blob'.
Restinga was relatively normal today which is election day. The Restinga football team took to the pitch with the Oceanography ship behind them (top right hand corner of apartments).Local people seen used to it now in it's quiet condition. I did see a note of optimism, Christmas decorations on a house on the front in Restinga, see photo.

The world's first renewable energy island
Earthquake-report.com likes to inform his readers about a "unique" El Hierro energy project.
El Hierro is set to become the first island in the world to be powered solely by renewable energy. The $87 million project will provide electricity for the island's 11,000 inhabitants using a combination of wind power and pumped water storage.
Today, El Hierro generates electricity with diesel oil transported from mainland terminals by oil tanker. The carbon impact is significant - in El Hierro’s case it amounts to 18,200 tons of CO2 per year in power generation emissions alone, an impact that the renewable energy project will eliminate.
The project consists of an 11.5 megawatt (MW) wind farm and an 11.3 MW hydroelectric pumped storage plant that will provide the island’s 11,000 inhabitants with 80 percent of their energy needs. The remaining 20 percent will be generated by solar thermal collectors and grid-connected photovoltaic systems.
Some text courtesy ABB, a leading partner in this great project
Reader Rob Gill is commenting that the island of Eigg was also "The world's first renewable energy island". A combination of hydro energy, solar cells and wind power made the island independent from diesel generators.

Ramón Margalef in the Las Calmas sea - Image webcam El Pinar authority + thanks to reader Daniel who captured it

Size of the La Restinga port pinnacles which can be seen on the Telefonica eruption webcam - image courtesy Joke Volta

- Today is election day in Spain - People of La Restinga can either vote in El Pinar or in La Restinga
- Joke is currently hanging around in La Restinga on search for news.
- Joke, who has no private car, is using the local bus service or the goodwill of some car drivers to get around on the island. She met Ian Carson on the bus this morning (Ian Carson is the earthquake-report.com reader who spends his vacation on El Hierro after hearing about the volcano activity - Ian Carson is sharing some of his pictures with the earthquake-report.com readers) .
- The Oceanographic ship Ramón Margalef was seen above the supposed eruption vent this morning. This will give us hopefully the exact depth of the erupting vent.

Eruption Webcam La Restinga : what is the size of the details ?
The La Restinga sea port wall doesn't look high at all on the eruption webcam.  Joke, in La Restinga on Thursday, went to the sea port wall and wanted to show where she was, swaying with everything she had during a couple of minutes ! We could not see her on the webcam. We asked here to make a picture in the port to have an idea of the height of the port wall.  To our great surprise, the pinnacles in the port are 6 meter high ! So, any eventual future stain, Jacuzzi etc in the Las Calmas sea behind the port wall has to be related to the size of the pinnacles in the port.

Data update 20/11 - 08:18 UTC
- 7 M+1.5 earthquakes since midnight
- Strongest earthquake being a M 3.7 at 03:15 with epicenter in the El Golfo bay
- Depth of the earthquakes since midnight : 15 to 21 km
- Harmonic tremor remains very strong
- GOOD air quality values this morning
- Windfinder.com weather outlook for today : wind will blow at 16 Knots, easing a little bit around noon - wave height 2.6 meter. The wind blows from the North to North East - it should be sunny in the afternoon (it will be hard to see any Jacuzzi, stains, etc in today's weather conditions)

Volcano Discussion Panel : If you are a person who wants to discuss and read about all aspects of volcanoes,  this discussion panel might be a very good place to hang around. Especially if we start speculating about what to happen next, this panel is a great place to look at. Give it a chance.
