Latest update courtesy of Enrique.

Translated.

more seismicity in the area of the teide central building - old peak and the caldera of seven cañadas, in the vicinity of Tenerife and between Gran Canaria and fuerteventura, Spain.- 04/07/2018.-follow movements in the Central area with 3 earthquakes located in the central area of the island with quantities of 0.7, 1.2 and 1.4 and depths of 6, 9 and 14 km respectively in the usual area And around.

There is also a 1.8-magnitude earthquake earthquake off the coast of candelaria at quite depth, which will surely vary when you check it out.

Finally there is a tremor that seems to have been noticed in several parts of several islands and that has finally been located between Gran Canaria and fuerteventura with a magnitude of 2.9 that will surely look up tomorrow and relocalizen.

If you have felt, don't forget to fill out the questionnaire is very important. (Henry)

Monthly report Tenerife by Involcan.

http://www.involcan.org/wp-content/uploads/GUAYOTA/guayota-tfe-es-co.pdf

The main map shows approx 14 earthquakes over the past month .

If you look at the link below click on the top right hand side 90 Dias there have actually been many more .

The thoughts of Enrique regarding the latest activity.

Translated.

the seismicity in Tenerife that passes in the teide area - old peak and the caldera de cañadas del Teide?, Canary Islands, Spain.- 06/07/2018.-although today has followed the in the area and in Around Tenerife, the truth is that the last earthquakes have left me thoughtful and neither white is white, nor black is black, only that sometimes depends a little from where you look. I explain in a brief analysis:

IGN: some 63 earthquakes have been located in the last 15 days and what draws attention is the difference in the position of these earthquakes, with some inconsistencies by the ign. The first is a huge asísmica area without earthquakes (Blue Table) which appears to be a processing error and / or the seismic model they are using, leading to a position error in the epicentres in the boiler area in all of its South Wall. Either they're further north or they're out on the South Ridge. The second, related to this one, is that seismic alignments do not square with the internal structure of the boiler, something rare happens with locations, among these things that teide is like the forbidden zone without earthquakes, which is very strange. Where the ign finds one on the outer edge of the caldera (Red Circle), involcan locate several.

Involcan: instead he has located 40 earthquakes this week and 20 last week that make a total of 60 in the last two weeks (14 days). They are mainly located under the teide volcano, the most logical and normal thinking of the entire hydrothermal system of it always has a base seismicity and that can be located, especially with that seismic station they have installed at the summit, as it is appreciated On the map. It is then seen that earthquakes are distributed better, more homogeneous without important areas and align according to the old peak teide axis on a line-Jan line by the summits area, also logical as it is the dorsal or edge of the boiler, Where more efforts are. Of course, earthquakes are also located in the southern area of the caldera south of teide and old peak in the ign area of the ign.

If I have to rely on data, those of involcan present much more quality and consistency than those of ign simply judging their position and comparing with distribution and knowing the structural geomorphology of the area of the central building and of the teide pipe furnace (Henry)

Comments by Enrique regarding this mornings updates by IGN.


Translated.

Edited (for confirming motivated by last-minute changes on ign's website) - earthquakes in Northern La Palma and seismicity in the teide area - old peak and around Tenerife, Canary Islands, Spain.- 09/07/2018.-this midnight and dawn we have had an interesting regional seismicity with 4 perfectly aligned earthquakes that have been given as if a zipper was treated from the most intense of 3.4 (and very deep) to the nw of the Island of LA Palma, then pass by a 3 to n of LA Palma, a 2.5 to ne of LA Palma and finally a 1.6 in Tenerife, all lined up on an nw line - se.

And now things that don't make sense or it costs much to assimilate when the data is analysed:

Edited: data to confirm motivated by last-minute changes on ign's web where they are relocating earthquakes, the north of LA Palma have disappeared. (they're driving me crazy, this is not receipt in an official site like ign do these things, it's shame and inadmissible and puts its credibility on soils)

1.- I hope you check well, because something is not going well, it may be that ign's automatic seismic detection system fails a little bit and some earthquakes have changed much, much. Specifically that of 1:37 h than being 150 km to the ne of the island of LA Palma and having magnitude 2.7 to be inside Tenerife in the boiler and having intensity of 0.7. The truth is that it is A little difficult to assimilate for not saying impossible a location error of more than 300 km and a change of magnitude like that.

2.- the following is reference to maps of maps, as it is possible that one has to see two maps of maps to get an idea of what happens in the canary islands as in one does not leave 3.4 and In the other, we don't go out under 1.5. When they'll put something that allows the user to select this and be able to make the most personalized maps

Another update by Enrique.

Translated.

The earthquake that had disappeared has already come out and eye on the signal at Maci. To note that it is the most powerful in the area I remember, I think there was a 1.8 previously, but no more, which would indicate and strengthen the hypothesis of an ongoing pressurization. If there was a ladder of free seismic energies, it would possibly begin to indicate a upturn of activity in the area only taking into account earthquakes in the boiler area.. Plus it is also located in the outline of what would be the magma chamber. (Henry)

New update courtesy of Enrique.

Translated.

more seismicity in the teide area - old peak and surroundings of Tenerife, Canary Islands, Spain.- 09/07/2018.-this time yes, we go with analysis, shortly before midnight and at dawn we have had one Interesting earthquake activity in Tenerife that only thinks that a reactivation process could be under way under the teide central building - old peak. If the data doesn't change, as we often dance this morning, I like the approach that Antonio has given:

- I'll change three deep and deep seismic tremors near the palm for a dozen more tremors under the teide - old beak!!!...
- Okay!!!

But let's go to what's interesting: it seems that the deep regional earthquake of 3.4 has removed the area under the old teide-Peak Central building like who shakes a bottle of champagne or coca cola, causing a spike in the seismicity of the Area of the magma chamber and an earthquake a little greater than we have custom (a 1.9) in that area can indicate that something has changed or broken. It is normal in active volcanoes that there are this type of blips after intense earthquakes nearby.

Visual analysis of seismic data represented on the map has a typically volcanic distribution, with circular morphology, which can be associated with the possible presence of a magma chamber in process of pressurization. This hypothesis is reinforced when one can also observe that most earthquakes and exponential are located forming a 3-Axis Star at 120 degrees indicating a pressure upwards or something that pushes up. Indeed, these 3 axes almost correspond to the three dorsal axes of the island, and one of them with the teide alignment - old peak. The Central point of all of these efforts, where the three axes intersect, would be the possible hypothetical eruption to have nothing better in the vertical of efforts and considering vertical promotion.

This point is to the SW of old peak, very close to the point of one of the last eruptions, noses of teide on June 9, 1798. in this area eruptions are usually of fonólítico or intermediate volcanic material, rarely basaltic. The last of 1798 was a basanite mixed with crystals crystals.

https://cologanvalois.blogspot.com/2011/05/erupcion-en-las-narices-del-teide-1798.html


Ultimately, it will have to be pending in coming days to see if we are at the gates of a new stage in what volcanic activity refers to the island of Tenerife and more specifically for its teide central building - old peak or on the contrary Of a mere seismic upturn caused by the deep regional earthquake of 3.4 to the nw of LA Palma.

Translated.

It was June 9, 1798, the island of Tenerife remained calm, summer began and the towns of the island were preparing for their parties. It was hot but the breeze of the trade winds cooled the atmosphere. In the early afternoon there was a horrendous roar and the earth shook. The inhabitants of Valle de la Orotava were startled, because they were not able to see what happened. A few hours later, with the night already well entered, there was a faint red light on the teide that at times shone accompanied by frightful roars that alarmed the population of the island.
In his house in Puerto de la Cruz the young Bernardo Cólogan sensed that the volcano had awakened. That was not good news for anyone except for the science lovers among whom he was. It was his opportunity.


El Teide in May 2011 with the tajinaste flowered

Determined not to miss the opportunity, in several hours he gathered the necessary equipment for a long walk to the Teide. The tour had already been done in previous years and it was not complicated, he knew the routes and the shortcuts, but this time it would not be for pleasure.
Tomás his father did not see with good eyes those scorn of explorer who permanently assaulted his son, and less after what happened in Garachico in 1706 when another volcano devastated that city, something that his own grandfather, the old don Bernardo Valois could see with his own eyes. Tomás, although he did not live it or knew his grandfather, he remembered hearing his father Juan tell how the lava scorched everything in its path, houses, granaries, churches and even people. It was a total disaster and I was afraid that the island would be devastated and with them its flourishing commerce businesses.

Oil from the eruption of the Garachico volcano by Ubaldo Bordanova.
 
Note: It is a free version of the anonymous painting attributed to a Garachico friar that, according to legend, he carried out while fleeing by sea. We can appreciate the natural cove that allowed the refuge of the boats of the strong sea of ​​the north of the island and that was completely destroyed by a lava language .
But the fear of childhood did not reach its adolescence and, that could prevent a 26 year old young man eager for experiences, to go up to see the eruption of a volcano !. Impossible. Furthermore, that was something never seen in the European continent and for which many of the great explorers of those countries would have given their lives just to be present.
No, I had already decided that I would go up immediately. With the help of some mules, and two assistants, they loaded water, food, clothes for the cold of the mountain and their notebooks where he expected to take notes of the event.
It was night and when we reached the Caldera del Teide, the darkness was total, only thanks to the moon could you walk without falling down. Without paths but the intuition of where he was going, they avoided boulders, devilish malpaises that ripped clothes and flesh until they reached the foot of Mount Teide.
But I could not see anything but an incessant roar, tremors of earth and the red of hell rising behind the profile of the mountain. Where was the rash? They followed the walk, something already exhausted and in a clear of the land after the Roques de García could see what was happening, it was the old peak that was crumbling by several points. Lava flowed out of its slope, and it flowed constantly but was punctuated by detonations and frightful blows.
But let it be the one who tells it:

Towards ten o'clock on the night of June 9, 1798, the populations of the southern band of Tenerife, and especially the part of Guia y Chío, the closest to the Canadas, there was a loud detonation and it was observed that the mountain of Chahorra, contiguous to the Pico de Teide, it launched flames and volcanic materials. These eruptions lasted, accompanied by a noise that spread the horror on the entire island, for three days. In a very short time another crater opened at the top of the mountain a mile from the first, weakening the action of the latter, which also vomited torrents of lava. Not far from this crater opened a third, whose explosions were happening very quickly. Finally, a fourth crack let out whirlwinds of smoke and burning stones. This eruption produced the four cones that are seen today and visited by Mr.


El Teide, Tenerife, Canary Islands
The four cones are placed on a slope so quickly that the first seems very high relative to those below. The main stream emerged from the third cone, whose walls are still covered with crystallized sulfur. The lava has flown in the Cañadas enclosure and has extended to the base of "Los Roques": its characters are those of a basilite mixed with crystals of rhyakolite and black Stony waste matter separated from metals during the smelting or refining of ore with metallic reflection.

All these different vents opened successively during the first seven days of the catastrophe. From a relation of the phenomenon made by Bernardo, eyewitness to it, we take the description:
The detonations of the volcano are of different natures: some resemble the boom of thunder, others the noise of a large mass boiling in an immense caldera, assuming that it is possible to form an idea of ​​a boiler of similar dimensions. Now the explosion is sudden, as fast as a continuous and very heavy artillery discharge; Now he imitates, until the mistake is made, the hiss and the special noise of the bomb. The detonation is always heard before the explosion. The torrents of lava that have arisen from the various craters have formed, in certain places, sets of stones of matter of more than twenty feet of elevation, and even when these massifs are not inflamed in the most distant points of the mouths that the they vomited, not for that reason they stop gaining ground.


The noses of Teide today
According to our observations, those that seemed more subdued, advance twelve feet in every two hours. These lavas barely smell any and can approach them without fear. The rocks thrown by the volcano go back to a great elevation, and the time that passes since they begin to rise until they fall, is of ten to fifteen seconds. Those that come out of the upper crater rise perpendicularly, while those of the others rise obliquely.
I will not try to describe this frightful eruption, that there is no painting capable of giving an exact idea of ​​it, and yet it would be impossible for the most fertile imagination to conceive such a picture, especially when in the midst of the darkness and silence of At night, you can hear the mooing of the mountain that echoes the echoes of the contours.
Then, suddenly, jets of flame come to illuminate these deserts places; scorched rocks plow through the atmosphere, collide with each other, break apart, crumble and scatter the fire in all directions.
These eruptions reproduce up to seven times per minute, and are accompanied by lava overflows. The sensations multiply in the presence of such an extraordinary spectacle and the powerful and terrible nature appears even more imposing.

(Bottom to the right appears Bernardo himself)

His description, later transcribed by Humboldt, happens to be one of the most precise of those collected by any eyewitness, together with another by Nicolás Segundo de Franchi. The naturalist Alejandro von Humboldt, who visited the island a year later, elaborated his description of the fact based on the stories and writings of Bernardo himself, after which he presented them to the scientific community. At the foot of the noses of Teide, which is what the holes caused by that eruption are now called, there is a plaque that recalls the young Bernardo.

Update by Enrique which he posted yesterday.

Translated.

Silence and silence for inaction.- 17 earthquakes located in Tenerife yesterday and no information. Today there are 4 on different sites and in iron, Canary Islands, Spain.- According to the pevolca, the agency responsible for volcanic surveillance, - ign - must report or convene the pevolca when exceeds the 10 limit. Earthquakes number from which the committee should be convened to communicate developments. (the microdisks under 1 do not count). But today there is no information, no official note, no warning, nothing at all, silence. This is not receipt, this is of shame and gives an unfortunate image of little public service, unprepared and much less effective.

Bad Information, bad data and worse managers who are making the people who visit have to devote to the corresponding virgin so that nothing happens to them by not knowing the current state of of. Reporting is not alarmist, it is to be prepared and if it is not done what happens, there are unpredictable natural disasters and many killed by chaos.

Someone knows something about a plan in case of eruption on the islands... no idea, no drills, or anything, only involcan is trying to reduce volcanic risk at the stroke of volcanic education talks. To know he's going to make a volcano in the future of a volcano you have to know his past, what he has done in the past and as much as they want to ignore or deny how obvious it happened in the past, it's a mistake to think it doesn't To repeat what happened in the past.

The site where they put the news is this, the latest, the activity of June 14th in iron:

http://www.ign.es/web/resources/volcanologia/html/CA_noticias.html


But life follows and today we continue with some movements in the area of fasnia and with an earthquake of magnitude 2.8 outstanding that has been felt in the island of iron island this morning. Yesterday we ended up with another earthquake of magnitude 2.1 South of Tenerife and another magnitude 2.2 on iron island that we will see if they do not relocate tomorrow.

And an informative information from the ign through their facebook facebook where they indicate that they change things, this is what they put, I wonder why they haven't put chie if it's already fixed. I suppose it is that at that station you see everything that happens on the island.... Sismicamente speaking clear. And why don't you notify your official page?? This every day is weirder. (Henry):

" NEWS IGN: 12-07-2018. CHANGE of reference station for visualization of earthquake activity on the island of iron

Due to the high level of noise recorded by the station station with origin in the activity of wind-wind wind generators, the reference station is changed for visualization of the earthquake activity of the iron island of the station a The Station Station. This station is not affected by this noise and shows better the island's earthquake activity ".

It looks like we have a new volcanic-volcanic swarm that has started at 20:25 h UTC in the boiler boiler area under the teide building - old peak. To see how many locate between today (if you locate any) and tomorrow at the IGN (Henry).

continue the volcanic swarm - volcanic in teide zone - old peak and the boiler caldera of teide, Canary Islands, Spain.- 13/07/2018.-today we have had two small shakes located by the ign in Tenerife (Blue On the map), with one of magnitude 1.1 in the upper area of the valley of la orotava on the nw ridge at 5 km deep and another that initially with magnitude 1.5 was in the area Under Ruiz Ravine In the realejos very close to the coast without depth and which have revised and moved more towards teide, staying 1 km deep and a magnitude of 1.3.

The most interesting of yesterday, plus 10 localized earthquakes, is that the IGN HAS LOCATED 3 earthquakes of the swarm that we marked yesterday (Red on map) in responses to s-SW-w of old peak with a first Swarm at 20:24 h UTC where two earthquakes of magnitude 0.9 and 1.4 to 16 and 17 km of depth have been located respectively.

Involcan's guayota report marks 56 events this week, and as earlier, several just over the peak of teide as is Norma and predictable, IGN, none, something happens to them or fear it or not to happen, they do not put An earthquake at the summit never. In Case this was little, and ign has also located 42 earthquakes from 7 to 13 July inclusive. It is a pity that there is not a list of consultation of earthquakes located by involcan, since by not leaving monthly bulletins, they do not come out. Or better still a earthquakes viewer, would be very good to the purest style style or imo in Iceland. (Henry)

Since the 2.3 earthquake IGN have not updated anymore earthquakes for the 13th July and none at all for the 14th July .

IMO its highly unlikely there have not been anymore earthquakes on these dates its another waiting game .

SISMICIDAD IN TENERIFE AND IN EL HIERRO, CANARY ISLANDS, SPAIN.- These days there are regional efforts in the Canary Islands in NS direction as shown by the general shear of efforts in the archipelago and it is being noticed especially in the area of ​​Tenerife- Costa of Fasnia - area of ​​the Enmedio volcano, with a lot of seismicity.

In Tenerife the seismicity continues in the area of ​​the Central Teide - Pico Viejo Building with a couple of microsismos located in the last days to the south of this building, to which add some more in all the surroundings, but nothing remarkable.

An earthquake of magnitude 2.6 has been located north of the strait that separates Gran Canaria from Fuerteventura at 30 km depth, which could be relocated.

On the other hand also in El Hierro has rebounded in the last hours with 3 earthquakes located in the interior Herreña Island (I do not know what happens that there are not 1.5 earthquakes lately in El Hierro, which is very strange); the first of magnitude 2.2 to 17 km of depth in the area of ​​summits in Sabinosa, the second of magnitude 2.1 to 16 km of depth in the area of ​​summits on the rim of the Tanganasoga volcano and the last of magnitude 1.9 to 9 km deep very close to the Orchilla lighthouse. In the spectrogram of CMCL, they are also noted as bands that alternate every 4 hours that are the result of the turbine cycle of the Hidroeólica del Hierro power plant.

In the spectrogram of the Island of La Palma there are some strong signals that look like the passage of fighters or planes that are perfectly marked in the seismogram at 09:30 and 14:08 and 14:16 ... as anecdotes.

I finish with the seismogram of EGOM, the most interesting, since the one in Tenerife is OFFLINE or without a signal, where echoes of hundreds of signals that at first seem to be anthropogenic noise are seen by the hours at which it happens, although the signal is very clear at low frequencies and you could think of the echoes of a seismic swarm in Tenerife or in the middle volcano, but as you can not see anything, you can not know.

So it seems that we have something that is not seen at the moment. Let's see what surprises we have tomorrow or not. Disinformation in its purest state, neglect and apathy and an international shame of volcanic surveillance service by the IGN. (Enrique)

AN EARTHQUAKE IN THE PALM AND THE CHRONICLE OF A PERMITTED DISASTER OF A VOLCANIC WATCH WITH ALMOST ANSWERING DATA IN THE GRAPHICS OF THE SISMOGRAMS AND PUBLIC SPECTROGRAMS OF TODO CANARIAS, SPAIN.- 18/07/2018 Highlight a localized earthquake of magnitude 2.0 initially and revised to 1.8 on the island of La Palma which is significant for its shallowness, about 7 km and revised 4.4 km under the South ridge of the island, about 1 km from the San Antonio volcano, next to the town of Canaries.

Yesterday we completed two, with an earthquake of magnitude 2.2 in the Sabinosa area on the Isla del Hierro at 17 km depth and another of magnitude 1.5 to 5 km at the NNW of the middle volcano at 20 km depth Between Tenerife and Gran Canaria. You see more lines and more earthquakes not located in the spectrograms, but this is what there is, until here we arrive.

But this lack of location is not missing network or this obsolete, is controlled neglect, programmed neglect and bad slob by the managers of the system of seismograms and spectrograms of the Canary Islands that do the minimum and least, with the excuse of not alarming the tourism, getting the opposite effect. The British tabloids to theirs, attack the tourism and if not the volcanoes, they are the toxic bacteria, that more gives with such to make damage ..

If we review the sensors of the archipelago, they will realize that in general, almost none of them works as it should be for good volcanic monitoring and all suffer from some problem that makes them almost useless to see anything. Seismograms are not worth anything if the earthquake is less than magnitude 3.0 and the spectrograms at least are seen, but are mostly saturated with noise. Even some are just facing the gallery, useless. We go for each of them:

EL HIERRO - Always the last, today the first, this sensor was in the CTIG station, but the noise did not show anything greater than 2.5. Now they have changed it to CMCL, which looks a bit better, just a little bit and is very affected by traffic. The question is, why do not they put CHIE again? Answer: why you see everything and not interested. It's been fixed and working for several years now. And another thing, why do not they detect earthquakes less than 1.5 in El Hierro? It is not interesting or important, and only seen in CHIE.

LA PALMA - The reference station is EHIG, located next to the road and where you can see a lot of traffic, not allowing you to see almost anything that happens on the island. For a while they put the TBT station, but you could see everything, even the floods of the ravine of anguish. They quickly changed. They have put new stations, but for the rest of mortals, nothing at all.

LA GOMERA .- The EGOM station is one of those that have not played much yet, they have lowered the resolution somewhat, but still behave quite well, although you can not see almost anything, you can see the echoes of when something happens in El Hierro , La Palma or Tenerife.

TENERIFE.- The CCAN station was the reference point, an unbeatable place, you can see everything, it is the one that you use as a reference for the number of events, but if you do not want them to be seen, you better remove it from the middle. For this they put MACI, which shared with the USIS network IRIS, served as a reference as a second station, and without shame none show a seismogram at the minimum resolution where nothing less than 2 in magnitude is seen, although the lines are appreciated of the earthquake in the seismogram.

GRAN CANARIA.- The EOSO station is located in an unbeatable location for surveillance, it had good resolution, until it began to locate uncomfortable things, then it was under resolution and although with noise, lately it presents many failures and an increase of unfiltered noise that makes this station unusable. Today seeing your spectrogram and seismogram is like watching the snow of the television without tuning, it is useless.

FUERTEVENTURA.- The CFUE station works relatively well, but it has noise and above all it has leaks, which generate a lot of parasites every time it rains. I do not know what this surveillance station does ... there is a worse one.

LANZAROTE.- An EFAM station, located on the beach of Famara, with all the noise of the sea, hardly anything less than 2.5 and on the other side of the island, far from any active volcano, as Timanafaya is not seen. He knows nothing at all, because nothing is seen at all. It is like having nothing having everything where it is not worth anything. And what they have been doing since 2004 to update the network and have not done anything at all.

Judge for yourselves and if you think that this is working well, I do not think so, rather it seems that they want to torpedo their own work so that nobody tells them what they have or what they do not (Enrique)

Latest update courtesy of Enrique.

SISMICIDAD IN TENERIFE, YOU MAY SEE VARIOUS IN THE AREA OF THE VOLCANO DE AMEDIO OR TEIDE-PICO VIEJO AND WE DO NOT KNOW MORE AS THERE IS NO MORE INFORMATION BY THE RESPONSIBLE IN VOLCANIC SURVEILLANCE, THE IGN, CANARY ISLANDS, SPAIN.- 19/07 / 2018.- Today we have an earthquake at 08: 07h UTC of magnitude 1.3 located in the area of ​​the swarm under the Teide-Pico Viejo Central Building, in the S area of ​​Pico Viejo in the caldera at a depth of 10.3 kilometers. Then there is another earthquake also of magnitude 1.3 located about 10 km east of the Enmedio volcano at a depth of 13 km. In addition, other signs of earthquakes and non-localized events are visible.

Yesterday 3 microsismos were located at the end of midnight in what seem like regional efforts in the area of ​​the island of Tenerife. Two to 11 and 5 km deep in the area of ​​the Caldera south of the Teide Building - Pico Viejo and one on the NE ridge, under the volcano of seven sources about 12 km.

Also today between 13:10 and 13:36 many vertical lines are observed in the MACI sensor and its echoes in the EGOM sensor of what looks like a new seismic-volcanic swarm, because it has all the appearance of a spasmodic tremor. This swarm seems to continue in following hours appreciating in the sensors of MACI and EGOM as a spasmodic tremor, possibly in the area of ​​the middle volcano.

The problem is that I do not know if these swarm events are under the area of ​​the Teide - Pico Viejo Building on the other side of the magma chamber, because they are not near the sensor or even I think it would be more feasible in the area of ​​the Enmedio Volcano. Maybe tomorrow they will locate something and clarify or continue in this mystery that is the blind surveillance of the volcanic activity of the Canarian archipelago where there are many questions and few answers.
