A deserved tribute and recognition for Enrique well deserved .

INVOLCAN hires doctor Carracedo and the researcher of 'Volcanes y Ciencia Hoy', to improve the prediction of eruptions ... (Innocents!)

 on Tuesday, December 28, 2021 Written by El Time


It is evident that, sooner or later, there will be another volcano, predictably in the coming decades, and it is necessary to improve the prediction systems so that the traffic light reaches red before the eruption appears, thus avoiding scenarios such as the one experienced in La Palma last September 19 when the volcano exploded with the surveillance system still in yellow.


For this reason, the Government of the Canary Islands has taken advantage of the recent announcement of the acquisition of INVOLCAN to achieve the desired unification of the science of study of volcanic eruptions in the archipelago. In other words, managing to unite the best in this field under the same entity.

Thus, the Volcanological Institute of the Canary Islands, taking advantage of the € 600,000 economic injection authorized by the Canary Islands Government in its recent purchase, has decided to incorporate new established professionals who will guarantee this objective, Doctor Juan Carlos Carracedo, a researcher at the CSIC worldwide known for his long experience in predicting future geological Events, and a "private investigator" (popularly known as Enrique) at the head of the prominent website 'Volcanes y Ciencia Hoy' with accurate analysis of the behavior of the La Palma volcano.

I may have jumped the gun and have not understood this statement I think is like an Aprils fool joke something to do with the day of the Innocents ????

On December 28th, Spaniards play pranks and jokes on each other, just like April Fool's Day. Local name. Dia de los Santos Inocentes. In Spain and Latin America ...

''Innocence has been sounded, I didn't find out until a couple hours ago that I got Involcan. I guess Carracedo is the same. Happy day of the innocents. All I have to do is smile and give thanks. (Enrique Hernandez from the mobile)''

30/12/2021 - 18:00h Canary Islands. - THE LA PALMA VOLCANO STILL STOPS. - THE ADVANCE LAVING FORWARD. - THE SESMIC ACTIVITY IN TENERIFE IN THE ADEJEZONE AND VILAFLOR CONTINUES TO BE NOTICED. - The Palma volcano continues to stop, there is no deep seismicity for days and the superficial seismicity (some just a few hundred meters deep) is decreasing slowly, in addition to being little concentrated and diffuse, which indicates a scattering of efforts along the way of the most active dorsal has been the NNW where the eruption point came from.
Where more seismic efforts are concentrated is in the area of the surface reservoir at 10-13 km under the old summit, where in addition the highest intensity or magnitude in the last 3 days, highlighting two of magnitude 2.3.

The volcano continues to degasify and the best thing is to see the video of yesterday's IGME, where you can see AEREA VIEW FROM YER DEL CONO.

https://www.youtube.com/watch?v=YcA2aW4JvfA

And in some area, there are still small gas vents or fumes showing very high temperature material inside like this video from today's INVOLCAN:

Following Hawaii's example, sometimes it's easier to do things about the lava flow itself without removing it and what is done is straightening and compacting the laundry area to put an alternative detour as soon as possible, which is seen perfectly in this v Idea of the cross from La Laguna, it is the most practical, fastest and economical option. There will be time to do better. By the way, firefighters are throwing water over the warmer areas to lower the temperature and avoid problems.

In Tenerife however the activity in the area of Adeje continues to remind us that this island is active and with several prominent earthquakes, but that is not a thing of now, comes from behind, and I do not talk about 2004, comes from much more back, from the decade of the 80 nothing less. I recommend you to read this PDF of the IGN that was published a little over a couple of years ago due to the occurrence of a major swamp in the area, it comes very well to catch up on how the situation is in Tenerife.

https://www.ign.es/web/resources/volcanologia/pdf/2019-07-09_Informe.pdf?fbclid=IwAR1VPdJW2c7WMffrS31vbS05WOJdjCYQAlMSE1d9ih7qpa5h_8QO-Q9eVTo

The list of the last three days, leaves us this view, with a small swarm with 3 earthquakes located on the 29th of this month between 6:38 and 6.40h and which indicates a small pressurization of the magma in that area 5-7 km and also as the area of Vilaflor notices some of that pressure and gives some seismicity:

But it is not the only thing that moves, in the area of the Caldera de Ucanca and under the Teide-Pico Viejo Building, there is another area with magma that is sensitive to these efforts and moves, specifically the reservoir or phonolithic magmatic camera that is found between 14 and 11 km deep.

However there are several areas with bags or sacks or magma reservoirs in Tenerife that give place to seismicity when the island has regional or local efforts, and that they could start moving towards the surface if they receive enough contribution from the more from the bottom as already ha past april 2004, october 2016, november 2017 etc.... but they weren't energetic enough to reach an eruption fortunately. In La Palma we had 8 swans and the 9th eruption occurred. We continue that it is not little and we are vigilant for what could happen. A greeting and a lot of encouragement. (Enrique)

Good ones. Enrique could you explain the signification of the red lines you have drawn on the maps. A million 🙏💕

05/01/2020 - 15:00h Canary Islands. - THE LA PALMA VOLCANO STILL STOPS. - ANTROPIC SIGNALS (produced by human activities) IN THE TREMOR, THE VOLCANO STILL STOPS. - REGIONAL EFFORTS AND BASE ACTIVITY IN TENERIFE. - ARTICLE ON TENERIFE SURFACE RESERVATIONS. - The volcano de la Palma is stopping, it keeps stopping, that's more than clear, but there are always things that disturb us, one of them is a strange signs in the graph of the tremor. Knowing that these brands are always reassuring and in this case they all look like very local signs, surely produced by human activities near the CENR sensor.

TREMOR GRAPHICS: There must be jobs of people near the CENR station who are causing those noise peaks in the tremor or RSAM signal, so I have had to use the TBT station tremor to see that it was nothing serious, and so on yes, it's a local noise. In the spectrogram you can't see the low frequencies of the typical magma noise that reddish the bottom, which makes me very calm. Besides, there is almost no seismicity, the volcano therefore continues to stop.

The problem is the same as always, the lack of open data that provokes such situations by not being able to contrast with other stations or media that despite being able to be public and paid with public funds, they are not.

INSIDE THE VOLCAN.

And meanwhile
 in Tenerife, several earthquakes produced by regional efforts are observed throughout the island concentrating on several points of the same.

1. - GARDEN ZONE - VILAFLOR

Follow the seismicity at 5-7 km in the area, indicating the magma bag or reservoir of the intruders passed between 2016 and 2020.

2. - PHONOLYTHIC MAGMATIC CAMERA ZONE - UCANCA

Follow the seismicity at 11-15 km in the boiler area, indicating a small pressurization by the regional efforts of the bag or phonolithic magma reservoir under the Teide-Pico Viejo and the Canadas del Teide.

es2022ahcop 04/01/2020 21:13:34 28.2432 -16.6909 13.0 km M 0.6 mbLg NE ISORA GUIDE. ITF

3. - ZONE OF THE SMOKING SYSTEM OF THE TEID

This area continues to be seismic, indicating minor presurizations in the smoke drains that climb the Teide. In this case, it is a very very small earthquake, so much of a negative magnitude.

es2022afxcr 04/01/2020 05:20:09 28.2675 -16.6382 2.0 km M -0.1 mbLg S LA GUANCHA. ITF

4. - FANCY ZONE - DORSAL NE

There is superficial microsismicity at 2-5 km, a typical situation where dispersion of opening efforts caused by regional tensions affecting the island are indicated, let's see what we have in the next few days.

es2022ahqwg 05/01/2020 04:26:47 28.2629 -16.5439 2.0 km M 1.0 mbLg W FASNIA. ITF

es2022aegca 03/01/2020 07:36:08 28.2730 -16.4793 5.0 km M 0.2 mbLg NW FASNIA. ITF

5. - ENEMY VOLCAN ZONE.

And of course, the area that never fails with all this, the Enmedio volcano, with a few more earthquakes. The depth is a little rare in the first two... but oh well.

es2022afjrv 03/01/2020 22:33:29 28.0604 -16.1632 0.0 km M 0.7 mbLg ATLANTIC-CANARIAS

es2022acitr 02/01/2020 06:41:22 28.0523 -16.1850 20.0 km M 0.9 mbLg ATLANTIC-CANARIAS

And for the end I leave what is most intriguing, a publication that talks to us about a possible operating model of the volcanic and fumarolic system of the Teide- Pico Viejo with the different parts involved, gases, aquifer, the volcano and reservoirs d and magma as well as smoking pipes using data of the geophysical compilations performed throughout the Teide building.

The most interesting thing about this study is that we may not have a large surface reservoir but 3 small ones one to 2km under the SE area of Pico Viejo, another 4-5 km just under the Teide and another about 2 km under the White Mountain. More than interesting.

INTERESTING ARTICLE ON THE FUNCTION OF THE VOLCANIC SYSTEM OF TENERIFE - TEIDE, OLD PICO.

Post-eruptive Activity Old Summit, #LaPalma (07-01-2022 09:00 UTC)

➡ Since the last announcement (4th day at 9:00 UTC), 9 earthquakes have been located on the island of La Palma, none of them has been felt by the population.

➡ The magnitudes are between 0.8 and 2.2 (mbLg). The hippocentras tracking continues under the central area of Cumbre Vieja in the same areas as in previous days.

➡ 3 earthquakes have been located at depths between 10 and 13 km and 6 at a depth less than 5 km. Earthquakes at a depth of more than 13 km have not been located.

➡ The network of permanent GNSS stations of the island does not show significant deformations that can be associated with volcanic activity.
➡ In today's day, the cloudiness prevents you from measuring the height of the cone.

➡ We share an image of the maintenance tasks of geochemical instrumentation around the volcanic cone.

🌋 The IGN continues its presence on the island, where the CAVE (Center of Attention and Eruption Surveillance) has been established, maintaining, denensifying and improving the surveillance network.

Post-eruptive Activity Old Summit, #LaPalma (11-01-2022 09:00 UTC)

➡ Since the last announcement (7th day at 9:00 UTC), 30 earthquakes have been located on the island of La Palma. The earthquake on Day 9 at 16:29, at 35 km deep and magnitude 2.6 mbLg, has been felt by the population, with intensity II (EMS98), in the epicentral area. This latest earthquake is the highest magnitude of the period considered. The magnitude is between 1.0 and 2.6 (mbLg).

➡ The location of hippocentres continues under the central area of Cumbre Vieja in the same areas as in previous days. 19 earthquakes have been located at a depth between 7 and 16 km, 9 at a depth less than 5 km and 2 at a depth of 35 km.

➡The network of permanent GNSS stations of the island does not show significant deformations that can be associated with volcanic activity.

🌋 The IGN continues its presence on the island, where the CAVE (Center of Attention and Eruption Surveillance) has been established, maintaining, denensifying and improving the surveillance network.

12/01/2020 - 20:00h Canary Islands. - LA PALMA VOLCANO STILL STOPS AND NO EFUSIVE ACTIVITY SINCE ALMOST A MONTH AGO. LIFE HAS TO FOLLOW- The volcanic traffic light continues in Red, in practice we are in a yellow-orange, having finished the eruption, but with the emergency of the Red, as we have to make sure that it will not restart and associated dangers good bye. We're in the Post-eruptive phase and you have to look at everything closely.
This cycle of activity seems to have passed and despite a small seismic recounts or activity these recent days shows no sign that it could indicate that it wants to return to the load, as the earthquakes are increasingly less and less magnitude and they are more scattered and I don't know accumulate in concrete points, it does not make swamp, which indicates that it continues to stop.

The cone follows its cooling process, with many cracks and continues to smoke and dump gas through many areas. Your mouths lined according to the eruptive dique will certainly be your most distinctive morphological feature, as well as the lava mouths that opened in the middle of the inhabited areas and even under the houses.

The Delta remains hot, the vapor continues to go out in some places, the heat and the interaction of the lava that continues to cool with the ocean water is what generates it.

On the other hand for many fissures and the ovens on the lava tubes continue to release gas, forming eflorescents and crystals of several minerals and reminding us that recently the magmatic material came down for them, windows inside some co Nuctions that are still very hot and will take time to cool down months, even years in areas of the thicker coladas.

GPS stabilize, as well as other parameters that are slowly returning to previous levels, which they have not yet done, especially in volcanic gases, seismicity that continues to drop and ground temperature that continues to cool.

And while, trying to recover normality, today I stay with this video of the Laguna Firefighters Park, which was about to be devoured by a laundry, but in the end I stay a few meters from the perimeter of it. The nearby school, instead if it was affected. They tell us the plans for that area to reset communications both over the laundry and by roads further north, which could be simpler, both options are being narrowed.

Much encouragement to all Palmeros. (Enrique)

PS: I've been a few months of hard work and take time to put the posts is not easy at all, so these days I have to catch up on several things and I will only comment the most resemble, with post in the days that I have time or because the current as In the morning, I'm request it for the occurrence of an event, (an Earthquake for example). Greetings and much encouragement.

OT but this shows how far waves can travel after a volcanic eruption.

18/01/2020 - 18:00h Canary Islands. - THE PALM VOLCANO KEEP CHILLING. - 4.8 AND 3.1 TO 100KM SOUTH OF LANZAROTE BY REGIONAL EFFORTS. FOLLOW THE WORK TO RECOVER NORMALITY. - Efforts in the Canary Islands area continue and today we have had an earthquake south of Lanzarote that reflect us these efforts in the Canaryan area and in the narrow area.

In fact in that narrow area you can see how Africa is pushing over the peninsula more than obvious and that I have scored with arrows of efforts over the area.

While on the island of Palma, the fact that there is still magma, that is safe, confined in reservoirs and in the own dique that has entered the island and whose exit is doubtful place at the eruptive point and formed the volcanic cone, where it is in cold in slow motion the lava expelled during the eruption and the one that has remained in those eruption holes or pipes (only comes out between 5 and 10% of the material to the surface, the rest stays in these ducts and forms a dique, as there are so many on the island).

In the area of the cone, in one of the secondary cones, we can see a smoker or a breather where the gases from one of these hot reservoirs escape, degasifying, one of which we can see with these magnificent explanations of Vicent and Soler of the IGME.

Inside houses/buildings located in the areas of La Bombilla and Puerto Naos have been detected abnormal values of carbon dioxide concentration (CO2) of volcanic origin that represent a danger to people. With the purpose of monitoring this volcanic danger, last January 9, 2022 at 16:32 hours the Volcanological Institute of the Canaryas (INVOLCAN) left a TDL optical sensor in operation to perform monitoring and measure in continuous mode CO2 concentration throughout the an optical road of 5.6 meters inside the ground floor of a building in Puerto Naos (Los Llanos de Aridane, La Palma, Canary Islands). Since then until yesterday January 17, 2022 at 5:37 p.m. 64204 CO2 concentration measures have been carried out. The graph shows the temporary evolution of this record reflecting an average value of 11921 ppm (1.19%), a maximum value of 44450 ppm (4.44%) and a minimum value of 763 ppm (0.07%).

Similarly in the graphic you can see different colored strips that reflect the Scientific Alert Scale for the Characterization of Indoor Air Quality established by CIVISA (Center of Information and Vigilância Sismovulcanica dos) Azores), a scientific entity of recognized prestige and with many years of experience in this problematic, as well as taking into account the limits of occupational exposure established by the European Agency for Safety and Health at Work.

26/01/2020 - 20:00h Canary Islands. - THE PALM VOLCANO KEEP CHILLING. - VOLCANIC SEMFORO RETURNS TO YELLOW. - Now it can be considered at all levels that things are going back to normal, it keeps cooling and stopping, which is always good news. Congratulations to all the palmers. Still emitting gases and with some seismicity, but with a steady trend over the past two weeks. This in practice means that the Cabildo de la Palma takes control of the operations of the Pevolca.

With this color, information is kept to the population and monitoring measures and monitoring of volcanic and seismic activity.

Now it's time to go back to the day and if possible, recover what you can from what the volcano took away and stay with what we learned for the future, since the volcanoes are like this, they come back late in the afternoon and that should never be forgotten.

There is a phrase that says: "Those who cannot remember the past are doomed to repeat it." The Japanese go beyond and say "Disasters happen because people forget." Hence the importance of preparing and getting to know them, not acting at the last minute. I hope the politicians get caught up, Tenerife has had several historical eruptions in the last 500 years and the guanches remember some more, there will be sooner than later another, although it does not have to be the next, there are more islands Volcanics in the Canary Islands.

Latest update courtesy of Enrique.

31/01/2020 - 19:15h Canary Islands. - TENERIFE REMINDS US TO STAY ACTIVE. - The seismic activity in Tenerife of recent days is little and does not mean any concern, but it is important to highlight where it occurs because it reminds us that just like the Palm or Iron, this island is alive inside and the magma could leaving when the moment.

At the moment it gives indications as a result of the regional efforts that form the seismic scissor with the NE-SW and NNE-SSW lines, which are cut in the Teide and indicate several things:

1. The first thing is the efforts along the marked lineups for which the last important swamps have occurred such as those in the Adeje area (see October 2016) with an earthquake in the NNE-SSW line and the other NE - SW what is the line up Teide - Pico Viejo and Nose eruption of Teide or Chahorra, what more is there to say.

2. - The second are small gas presurizations in the hydrothermal pipeline of the Teide with small microsisms one of them at just 400m deep and another at 3500 meters, on the basis of the said hydrothermal system.

3. - But there are more interesting things, in the Caldera is what most respect imposes of everything, the phonolithic magmatic reservoir where the last magma intrusions have ended, what we do not know is how much it will mature, but when it's ready we h you will know, while it gives seismicity for little ones pressurizations both in the intrusive conduit below 18km, as in the walls of the Chamber at 13-14km with a small swamp under Chahorra and even some higher at 11km.

01/02/2020 - 21:00h Canary Islands. - FEELINGS AFTER ERUPTION, IN SOME Places GAS, SHAKES AND LIGHT VIBRATIONS. THE MAGMA GO DEEP. - Posteruptive activity continues in the Palma with different impressions, but throwing a curious fact, the magma continues to move deep to rebalance the system. I'm going to see if I explain myself clearly with an analogue.

When one pumps a well, the water flows around it towards the well (the erupting point of the volcano would be the well), but when the pump stops (the eruption ends), until the system recovers the balance and the well recovers its level, it takes time, c so much or more the pumping, is the recovery of the water level, where the water level is rising, moving underground water into the well, until the system is re-balanced. In that span of time, the magma flows from the furthest areas to the eruptive area.

Many will say that this from where I get it, because this looks very well in the significant deformation of LP05 that sinks these days indicating a migration from the deep reservoir to the most superficial area of Cumbre Vieja passing through deb Garlic of El Mazo, (What too something sinks today) where they sure have noticed that "river" of lava that has been ringing under their feet for 4 months.
The other source is that in the spectrograms something makes noise at around 1 to 3Hz, especially at 3 which is deep magma movement and then there are a lot of LP events over the long run, such as long vibrations that indicate small events of Fluids spraying in depth and be marked by hundreds a day.

And although the seismicity is at low levels, the rate of energy emission remains stable over the last 30 days, not indicating changes in the system, but that does not remove that noise and reports of many people are heard, not to mention the plague that bring the volcanic gases that continue, today looking at the day with a yellow color in the sky of the most suspicious. In the lightbulb area being a low point and just below the exit conduit area, we will have gas for months, but with a low tendency, we hope normality can be restored as soon as possible.

I have to emphasize that they have contacted at least 5 people from different places of the island where they are feeling "things" in some cases with concern, because they feel the noise of the "river" or "the underground blows" of stones that are heard have and feel like rolling with vibrations, that the mobile or a bottle register as earthquakes between 1 and 2, so it's no story.

From here tell them to be calm, as long as the eruptive conduction is closed and that the volcanic system does not pressurize or swarm, there is nothing to fear, it will not open anything. For that I would warn with stronger earthquakes and deformation. It's still stopping but it's not over yet.

Ultimately, this continues to calm down and the magma is "filling" the gap left by the lava emission of the volcano, especially in the last days of the eruption where I change the eruptive pressure mechanism to drainage, reason for now to pass and I stand. As soon as the system adjusts and rebalances, it will pressurize as before and we'll be back at the starting point, but getting to this point could still take months, even years.

That's it, I don't rule out any deep earthquake sense above 3 or even 4 with these re-adjustments, but isolated. A lot of encouragement to all the palmers. (Enrique)
