The M4.0 was downgraded to a M3.7.

Intensity earthquakes continue in the south of La Palma
The last one registered at 6:58 p.m. in Fuencaliente was 3.7 degrees on the Richter scale.

The National Geographic Institute (IGN) continues to report punctually on the latest earthquakes located in the southern part of the island of La Palma, around the Cumbre Vieja volcano. The last Earthquake registered and that has been noticed by the population was at 6:58 p.m. this afternoon, in the Fuencaliente area, with 3.7 degrees on the Richter scale and occurred at a depth of 14 kilometers.

The 'seismic swarm' in the south of La Palma has once again increased its activity with more than 40 earthquakes last night - from 8:00 p.m. on Sunday - in the municipalities of Fuencaliente and Mazo, near the southern part of the island .

The most prominent among those located by the National Geographic Institute (IGN) are one in the southwest of Mazo, of magnitude 3.4, at a depth of 13 kilometers and at 5:20 a.m., and another to the northeast of Fuencaliente, also of magnitude 3 , 4, at a depth of 14 kilometers and at 04.36 hours.

In general, earthquakes are still maintained at high depths that fluctuate between 7 and 14 kilometers and with magnitudes that oscillate between 2.3 and 3.4 on the Richter Scale, and two of them are felt by the population.

Some comments taken from Volcanes y Ciencia Hoy written last night by islanders that live on La Palma.


Isabel Garcia Fernandez

Pues llevo desde que empezo esto pidiendo información yo vivo en los Llanos llevo oxigeno y no puedo salir corriendo con mis aparatos
Cansada de llamar a todos sitios y no obtengo respuesta de nadie
Que impotencia


Well I've been since I started this asking for information I live in the Llanos I have oxygen and can't run away with my devices
Tired of calling everywhere and getting no response from anyone
How helpless


Isabel Garcia Fernandez

Pero como se puede consentir que las autoridades de la isla en especial la alcaldesa de Los Llanos no nos den ni el menor indicativo de como se puede poner la situación
Yo estoy con una ansiedad que no me deja ni respirar


But how can you consent to the authorities of the island especially the mayor of Los Llanos do not give us the slightest indication of how you can put the situation
I'm with anxiety that doesn't let me breathe


Ana Jimenez
Que miedo esta noche. El pica pica nos cogió caminando en las calles de los Llanos, parecía que los edificios se iban a caer. Temblores verticales, se sentía como si estuvieran golpeando el suelo desde abajo, pensé que el suelo se iba a abrir.


So scary tonight. The itch caught us walking in the streets of the Llanos, it looked like the buildings were going to fall. Vertical tremors, it felt like they were hitting the ground from the bottom, I thought the ground was going to open.

05/10/2021-8:30 h Canary Islands.- LA PALMA ISLAND ERUPTION.- SISMICITY ACCENTED,-3.9 TONIGHT AND UPLOADING...- Continued seismicity increasing, according to the parametric function of a cantor that parameters over the freed seismic energy accumulated and tells us that the swarm continues to reactivate without visas to stop increasing its energy emission in the next few hours so there could be some 4° magnitude Earthquake more. Take precautions and in case of moderate to strong Earthquake, the most important thing is to protect your head.

For many this I tell you may find something my personal or intuition, nothing further from reality, is a scientific study of a mathematical function and its variation that tells us how it is the process within the volcano, the Earthquake-volcanic swarm caused by the magma entrance under the volcano of Old Summit responds to that equation, and what it tells us, it tells me, and to all the vulcanologists who know how to interpret the graphics. This is no joke, it's a serious thing, as things from now on can get ugly as far as seismicity refers to this second swarm as it's reaching high seismic energy emission levels or rates. (Enrique)

Graphics:

https://www.volcanodiscovery.com/la-palma-earthquakes.html

And since everything doesn't have to be horrible, I leave this video from the IGME where you see the pyroclast cone perfectly. In fact I see the eruption different, with magma more viscous and explosive, let's see what the samples say because this is important, because it is not a magma that comes from the mantle, but a tefrite that comes from ancient magmatic cameras located under the island, a fact that makes the palm a lava own and unique as it couldn't be any other way.

https://twitter.com/i/status/1445144623358398469

Another thing that catches my eye is that this Earthquake is deep, which translates to the channel of magma contribution from deep levels to 30 km or below the island should be subjected to great tensions and pressures by magma's big step to hier levels, reflected in these highly accentuated movements. The other consequence is that we will have eruption for a while, weeks at least, without stopping or loosening. (Enrique)

The south of La Palma registers more than 120 earthquakes in 24 hours
The most intense, 3.9 degrees, was registered early today

The southern area of ​​the island of La Palma, where the volcano eruption is located, has registered more than 120 earthquakes in the last 24 hours since this Monday, of which 12 were felt by the population.

The highest magnitude on Monday was 3.7 degrees, a record that was surpassed this Tuesday with another Earthquake registered in Villa de Mazo of 3.9 degrees at a depth of 11 kilometers.

Likewise, of the total number of earthquakes, six have occurred at great depth, between 30 and 36 kilometers, according to the National Geographic Institute.

Volcanic tremor pulses have also been produced as activity intensified and the column height was 4,500 meters.

The Volcanological Institute of the Canary Islands (Involcan) estimates that the amount of sulfur dioxide (SO2) emitted by the volcano on the Spanish island of La Palma since it erupted on September 19 amounts to about 250,000 tons.

This calculation, Involcan pointed out in social networks, can be considered "an underestimated value" since it is based on the realization of SO2 emission measurements in land mobile position, which currently have "important limitations due to several factors."

Mike Hayward comments I think the deleted EQ he mentioned is the M4.7 that was wrote about in the paper I posted this earlier.


It's hours ago it seems like it has bothered and they deleted it:

Good morning to tod@s.Destacar great seismicity either low frequency or greater than two we continue with the great swarm yesterday that we added a couple of them magnitude 3 or almost 4, so we appreciate it on spectrums is what I'm nominating an unstable area. Whatever wants to get out is on the way we started as we started before it erupted for the first time they want to or won't go up. A particular movement we have it removed from the area of the swarm one of magnitude above the rest most south of the iron that then relocate it between 11 and 7 km deep in fuencaliente there is a delicate situation and the authorities without even give or an explanation for not giving them ask me my people there, because no one notice that seismic activity would be increasing any of the authorities, because it is not that it will increase will go to more unfortunately and people should have instructions to do in case of moves BEFORE DURING AND AFTER magnitude 4 produced by that magma approaching the surface. It seems disrespectful to me what you are doing according to the BOE you have an obligation to give real and truthful information can not be played with the lives of people, you have to explain but for them to understand not to generate more doubts, so no would have to turn to sources that are not you shame I feel that if air quality is good and quadruple the values allowed to be harmful to health, if everything is normal I feel to say that if it will be a normal situation if before an eruption is normal. But it's normal where it's known to be being made to say if there's another possibility of eruption, nature is unpredictable, rather NATURE is warning that something is coming and ignoring those signs you might have a serious problem. The magmatic camera keeps filling up and makes it look at a movement of 3.9 to 34 km deep, it's time to make a right decision before the volcano talks more day by day alone saying everything is normal, when you are have spent hours and hours on the ground moving during the early morning just telling you something that volcano goes 7 steps ahead of them I just have to thank those emergency responders for being there always and not knowing what's really there..

We continue with yesterday's great swarm hybrid VT movements and low frequency, swarm again with each other just know that there are no catastrophes there are bad decisions (MIK3)

At last someone else another geologist speaks up.

New leaks continue to worry, and the possibility of them reaching saved buildings. The lava delta already covers 32 hectares, with a growth of two hectares in a single day. The ash completely covers the streets and furniture of evicted towns, such as Puerto Naos. More than a thousand buildings have already been affected by the lava, with a total of 430 rescued.

Detected a new fissure 100 meters from the main cone of the La Palma volcano, although without an eruptive character
The data on seismicity, geochemistry and deformation suggest that "the end of the eruption is not near", that it is in the "mature" phase, so that we must prepare "to spend many days", the experts have reported after the committee. of scientists from the Canary Islands Volcanic Emergency Plan (Pevolca)
- The wash is already over a kilometer wide in some sections


The director in the Canary Islands of the National Geographic Institute (IGN), María José Blanco, revealed this Tuesday, during the press conference after the scientific committee of the Canary Islands Volcanic Emergency Plan (Pevolca), that experts have detected the opening of a fissure area about 100 meters northeast of the main cone of the volcano with emission of gases and high temperature soil that, in principle, has no eruptive character.

Likewise, he explained that the seismicity, geochemistry and deformation data suggest that the end of the eruption of the La Palma volcano, which is in the "mature" phase, is not near, so that we must prepare "to spend many days" , has stated.

He has also indicated that the Weather forecast indicates that this Wednesday afternoon the winds will turn the column of ash and gases from the plume towards the northeast slope of the island, which could affect the operation of the La Palma airport.

For his part, the technical director of Pevolca, Miguel Ángel Morcuende, has reported that so far the wash has destroyed 726 buildings, of which 605 are homes; 58, buildings for agricultural use, and 30, for industrial use, according to the Cadastre data registered until the afternoon of this Monday.

Morcuende explained that these figures differ from those recorded by the Copernicus satellite, since it detects any point that may be a building, which is misleading "because in the end it may be a pergola, a precarious chicken coop, an abandoned haystack, among other constructions ".

Specifically, the latest data provided by Copernicus speak of 1,154 buildings affected by the eruption, of which 1,046 would have been destroyed by lava and 108 would be damaged or at risk of collapse.

The flow affects 6.74 hectares more than in the previous day
The latest measurements point to 420 hectares affected by the lava, an increase of 6.74 compared to the day before, in a perimeter of 36.24 kilometers and a maximum width of 1,250 meters.

The lava delta that has entered the sea for now occupies an area of ​​more than 36 hectares and has advanced 540 meters from the coastline.

The air quality on the island has improved compared to previous days thanks to the entry of trade winds. While the marine plume of water vapor and hydrochloric acid that occurs in the contact of the lava with the sea remains in a reduced area near the delta.

Seismicity is increasing in terms of number of episodes and magnitude, and it has also been more felt by the population, especially in Fuencaliente and Villa de Mazo, but it remains at average depths of ten or more kilometers.

Daily sulfur dioxide emissions were 1,200 tons on Monday, with a cumulative 250,000 tons since the eruption began, and the volume of magma expelled could be at 45 million cubic meters.

A "safe" island for visitors
So far, the Fuencaliente hotel has housed 209 people of the approximately 6,000 evacuees and 553 people work in the emergency operation, explained Morcuende, who has insisted that La Palma is a safe island for all visitors and that only on 8 % of its surface is affected by the volcano.

Latest update courtesy of Enrique.

05/10/2021-19:00 h Canary Islands.- LA PALMA ISLAND ERUPTION.- SEEMS LIKE THE SISMICITY IS CALMED, BUT THERE ARE MANY FEARS AND NOISE.- It's too early to be sure but lots of vibrations are being noticed in the plains area in houses with crunching doors and continuous windows and a noise like a river under their feet. But what catches my eye is that two sources of noise are noticed, one in the volcano emission zone and one underground to the south.

It's really not reassuring at all. If there is no more strong seismicity than I hope in the next few hours with an event in the 4 environment would mean that the system of the Earthquake-volcanic swarm is coming to its maximum and could have broken or broken in the next couple hours, which it would mean that magma would make its way to the surface, either through the existing eruptive canal or a new one, I don't know, it's too soon.

What if I know, when I break up, it will start climbing from the 10 km and would be like an elephant in a cacharía for the noise it will make and should cause seismicity as it ascends, so the earthquakes hanger less than 3 km from now on are vital to know where it's going.

For making a comparison, this is like a plank we put a weight on, and at a point it starts crunching... CRA CRA CRA that would be the earthquakes of the swarm.... but there comes a time that breaks into a sound CRACK ′′ and yields, that's the shooting Earthquake and the moment the rock lets go the magma on its way to the surface. That point is near, otherwise it has already occurred in some of the earthquakes we carry, but I do not see earthquakes that would be the ultimate sign.

For making another comparison, an eruption at the end is like when a reservoir bursts... first a crack is made little by little, but it gets more powerful as the exhaust gets bigger and eventually ends with a red, in this case of magma. I hope he does it for the existing eruptive point channel and not for a new one.

Now you have to monitor the hier earthquakes and deformation, the next 24-48-72 h will be intense to truth, we'll see what happens in the end, hope it doesn't hurt much more and it's over..

As for flow, I have already been able to update the map, I have been working on two days to see where the flow of the eruption move and the good news is that both North and South are standing and not threatening new structures, except we have an overflow of the laavic canal, as has already happened in some places with small overflows. I'm giving you more details in some answers. (Enrique)

This is how they feel (and hear) the explosions of the La Palma Volcano from the air.
Flying drones in the vicinity is not always an easy task, and at any time and without warning, this can happen.
This is also one of the reasons to maintain a security perimeter (not only lava is dangerous).
Similarly, in nearby towns, it is requested not to stay longer than necessary near windows and glass.

Scientists separate the increase in earthquakes from the appearance of another eruptive focus
From Monday to Tuesday, there were a hundred earthquakes, the largest with magnitude 3.9. According to experts, nothing indicates the opening of another issuing center

The increase in seismicity felt around the Cumbre Vieja volcano is creating alarm among the population residing to the south and west of the eruptive fracture. However, the Pevolca scientists maintain that this increase in earthquakes is not the prelude to the opening of a new eruptive rift in another area of ​​the island, since the earthquakes are occurring at a considerable depth and no substantial deformations have been detected. on the ground that indicate a new magmatic intrusion under the island.

Furthermore, the frequency, quantity and magnitude of recent earthquakes differ greatly from the seismic swarm that led to the eruption at Cabeza de Vaca . In fact, between September 12 and 19, there were about 26,000 earthquakes in the area, of which 1,600 were located. Most of them had a magnitude equal to or less than 2 on the Richter scale and only a minimal part exceeded magnitude 3.

However, between September 21 and October 5, 335 seismic Events have been located. The highest magnitude reached 3.9 degrees and occurred at 4.36 in the morning yesterday at a depth of 38 kilometers , in the part of the Cumbre Vieja ridge located in the municipality of Mazo.

Seismicity is increasing in terms of the number of episodes and magnitude and has also been more felt by the population, especially in the towns of Fuencaliente and Villa de Mazo, but it remains at depths of between 15 and 10 kilometers , as explained yesterday by the Pevolca technical director, Miguel Ángel Morcuende.

On Monday there were 98 earthquakes in Cumbre Vieja, of which 70 had a magnitude between 2 and 3, and another 28 exceeded 3. Yesterday, the IGN located 35 earthquakes in the area, of which 18 exceeded magnitude 3.

« The seismic swarm is centered in the vicinity of where it was the first days. If anything more to the southeast, for what they are more felt in the towns of Fuencaliente and Villa de Mazo, "Morcuende highlighted, who stressed that it is not a shallow seismicity, but a deep or medium deep one. " The rest of the parameters that could tell us about the appearance of a new emission center in these municipalities are null ", highlighted the director of the emergency plan to reassure the people who live at the foot of the eastern and southern slopes of Cumbre Vieja . However, he warned that earthquakes will continue to be noticed and that earthquakes of greater magnitude or intensity may even be recorded.

" C hen a system has an open exhaust valve, does not need to find a point that energy would cost more open surface , " he said in remarks to Radio Nacional director of the Institute National Geographic (IGN) in the Canary Islands, Maria José Blanco, who maintains that these earthquakes are probably due to "a feedback of the magma system at depth",

Blanco stressed that in the only eruption of which there is an instrumental record, that of the underwater Tagoro volcano in El Hierro, something similar happened . «It started in July 2011 with a very small seismicity in El Golfo. It crossed the island from north to south in September and finally, on October 10, the eruption began in the Mar de las Calmas. Later, the seismicity returned in November to the same point of El Golfo with greater and more intense magnitudes, but there was no second eruption ", explains the geologist.

In any case, Blanco does not rule out the opening of other emission centers in the vicinity of the volcanic cone. In fact, yesterday a fissure was located to the north of the cone with emission of gases and high temperature in the ground that, for the moment, does not have much importance, said Blanco at the Pevolca press conference.

LATEST DATA INDICATES THAT THE ERUPTION IN LA PALMA ‘IS NOT ENDING SOON`

2021/10/06 08:14:19 Written by Canarian Weekly Tenerife
The latest data from Pevolca on seismicity, geochemistry and deformation indicates that the eruption in La Palma is not ending soon, as the volcano has entered a "mature phase” of “steady” eruption which it could be in for days, weeks, or months.

After yesterday`s daily meeting of the scientific committee, the director of the IGN, María José Blanco, said that the Weather forecast indicates that winds will turn today pushing the column of ash and gases from the plume towards the northeast slope of the island, which could affect the island`s airport.

In addition, scientists have confirmed that there are no new emission points, although they have detected the opening of a fissure zone about a hundred metres northeast of the main cone of the volcano with emission of gases and soil at high temperature, without being an actual eruption, which they say is of little importance.

Pevolca experts believe that the most probable thing in the short term is that the lava, which is still quite fluid, will continue to head towards the sea following the path already made by the original flow, although vigilance is being maintained in the event that it broadens or takes a new direction.

The latest measurements show that 420 hectares of land are now affected by lava, an increase of 6.74 compared to the day before, inside a perimeter of 36.24 kilometres. The lava delta currently occupies an area of ​​more than 36 hectares and has advanced 540 metres from the coastline. The plume of water vapour and hydrochloric acid that is being produced when the lava meets the sea is being kept in a localised area near the delta.

Finally, data shows that the emissions of sulphur dioxide are 1,200 tons a day, with over a quarter of a million tons being emitted since the beginning of the eruption.

The CSIC studies the impact of a possible extreme geological catastrophe in Tenerife
Scientists from Geosciences Barcelona investigate the probabilities and consequences of a cascading episode on the island that would start from a volcanic eruption with earthquakes, landslides and tsunamis

A new study by CSIC Geosciences Barcelona (GEO3BCN-CSIC) assesses the impact that an episode of multiple extreme Events in Tenerife would currently have. This publication, led by the GEO3BCN-CSIC predoctoral researcher, Marta López Saavedra, reconstructs the last great geological event in cascade that took place on the Canary Island to analyze what consequences it would have if it occurred today.

Extreme geological Events are natural phenomena (volcanic eruptions, earthquakes, landslides or tsunamis) of low probability, but high impact, which represent a risk for today's society due to their difficulty in predicting them. These episodes, which can produce chain effects and have a significant local and global impact, are potentially likely on volcanic islands, such as the Canary archipelago.

The latter paper, published in the journal Journal of Geophysical Research: Solid Earth , aims to predict the potential range of a succession of ends cascading Events that may occur during an eruption formation similar boiler which happened 180,000 years ago in the eruption of El Abrigo. Joan Martí, researcher at the CSIC, Jose Luis Rubio, from the Autonomous University of Barcelona, ​​and Karim Kelfoun, from Laboratoire Magmas et Volcans at the Université Clermont Auvergne have collaborated in the preparation of this study.

According to the results of the work, the obtained scenarios show that the main urban centers and the possible evacuation routes of Tenerife would be affected, since they could be covered by the deposits of the pyroclastic flows and probably by the ash fall.

Furthermore, the seismicity concentrated in the central part of the island during a collapse event of the central part of the volcanic edifice, such as the one that occurred 180 thousand years ago, would produce “catastrophic” effects in various parts of the island and trigger a “devastating” landslide in the Icod valley. This landslide, in turn, would produce a tsunami that would likely have a severe impact not only on the north and west coasts of Tenerife but also on other coasts of the Canary archipelago.

“At present, the volcanic system of Tenerife is not in a situation similar to that of the last caldera eruption. In fact, reaching the conditions for an eruption like that of El Abrigo can take thousands to hundreds of thousands of years ”, underlines Marta López Saavedra, main author of the article entitled Cascading Effects of Extreme Geohazards on Tenerife (Canary Islands) . And, he adds, "at the current stage, the Teide and Pico Viejo volcanoes still seem too young to reach these conditions."

López Saavedra insists that "the chances of an eruption like El Abrigo occurring today are very low", although he clarifies that "zero risk does not exist and unfortunately eruptions cannot yet be predicted."

Investigate to prevent
“The results obtained in our study probably show the most catastrophic scenario that can be expected for Tenerife. This makes it possible to establish a maximum limit to the range of situations that may arise in order to design better risk management on this island without exceeding minor Events, or falling short in the event of higher impact Events ”, explains the researcher.

López Saavedra considers that this analysis will contribute to “improving the current Canary Islands Emergency Management Plan (PEVOLCA) by detailing the appropriate danger scenarios and optimizing mitigation actions long before any emergency caused by these extreme Events of multiple dangers occurs. ”.

The researcher highlights the importance of implementing continuous improvements in disaster reduction policies by the agencies responsible for emergency management. "This implies more information and training for the population of the Canary Islands," he stresses.

Technological advance: key to Geosciences research
To carry out this analysis, modeling software has been combined with Geographic Information Systems to simulate each event separately and, subsequently, analyze the global result of all the scenarios obtained.

The research team used the VORIS 2.0.1 software. to obtain the area potentially affected by pyroclastic density currents; a plugin for QGIS 2.14 that allows to calculate the impact of a possible Earthquake; Rocscience Inc.'s SLIDE software for analyzing slope stability under seismic conditions; and finally, the VolcFlow software to simulate the propagation in space and time of the possible tsunami, as a consequence of the collision of the landslide against the ocean.

As far as day to day, the eruption is in a more stable phase, there is nothing more to see how the tremor holds, although with some explosions from time to time and lightly rise, it is feeding without pause to the flow going down by the hillside.

As far as the descent of flow to the sea is concerned by the lavic channels, which does not remove that from time to time like today, there is an overflow of laundry and a new arm of lava separates new areas with structures and plantations .. It's what happened today very close to the end along the mountain of Todoque near the delta, from which I pulled a graphic.

Binter cancels Thursday's flights with La Palma due to the ash cloud
The company explains in a statement that it has been forced to make this decision due to force majeure, since the situation of suspended ash has worsened considerably.

Wednesday, 6 October 2021, 18:36
Binter has reported that due to the evolution of the ash cloud from the volcanic eruption on La Palma, and the latest Weather forecasts about the behavior of winds at height, it temporarily cancels the flights scheduled for Thursday you see with the Island.

The airline has indicated in a statement that it has been forced to make this decision due to force majeure, since the situation of suspended ash has worsened considerably and is expected to continue like this at least on Thursday, not allowing it to develop. the operation with the necessary security requirements.

The company explained that it is keeping an eye on the meteorological evolution , so that it will try to recover the activity as soon as possible and provided that the conditions allow to resume the flights, guaranteeing their safety.

For now, the rest of the flight schedule in the Archipelago continues to develop normally.

It also indicates that by attending through the usual channels the requests for changes or refunds that may be received by the affected passengers on these flights.

Due to the exceptional situation that is being lived, Binter will inform of any news or change that could occur, through its usual channels.

Likewise, the airline informs its customers that before going to the airport they check the status of their flight in the official company media.

06/10/2021-21:00 h Canary Islands.- LA PALMA ISLAND ERUPTION.- ENJOY SISM-VOLCANIC CONTINUES AND Typical THINGS FROM AN ERUPTION, FIGHT HAIRS, VOLCANI TUBES AND FEATURES GAS ON OCEAN ENTRY. - For many this will surprise you, I hear from the networks that asbestos appears... nothing further, it's a bull, but if there are volcanic fibers that are typical in lava volcanoes when there is a lot of wind or entrances to the ocean ..

They are like hair.. they are fibrous silicates that are known as hair or hair of the Goddess I fought. It usually appears on the beaches as normal in many eruptions when it washes liquid from the lava river that goes down the very hot volcanic tube comes into contact with seawater. I've put a photo of Hawaii for you to see what it is like and I'm leaving you the wikipedia link on the subject.

https://es.wikipedia.org/wiki/Cabellos_de_Pele?fbclid=IwAR1tjuYi2gFj7A_MA0edRGN2cB2frhTnq9qZOMvEX1iFkjrtOSyPUCjqSms

But to form these Hairs of Fight, the lava must be very hot and fluid, and this has an explanation. The lava coming out of the volcano is beginning to form tubes and galleries circulating the very fluid and high temperature and relatively quickly so that it reaches the coast at very high temperature. And one of the longest volcanic tubes in the world is in Tenerife nothing less, The Wind Cave System-Leftover.

https://es.wikipedia.org/wiki/Tubo_de_lava?fbclid=IwAR1FFVEG90CSiC7Nhxj9ulrP3kHnJw-rT9e8oBI1HrEBkX_G55XNhzzTUwo

It should be stressed that I am already seeing several lava tubes, which also have another advantage, prevent the laavic channel from overflowing and you can see where the tube is going because they form very characteristic structures, the ovens... another thing of volcanoes ...- the best known in the Canary Islands is the ′′ Mantle of the Virgin ′′ in Timanfaya..-where smoke and gas from the volcanic tube comes out.

I'll tell you more things that will form, but I'm going to the other theme, the vapor feathers and gases that come out of the magma's direct interaction with the ocean, are not anything, but when you pass under the feather of Gases and ash, things fall on top of you, like crystals, hair of Peleé, and very acid water (eye to clothes) without having that sometimes in the coastal zone accumulate many gases, which move to oxygen, may cause some situation dangerous, even deadly (In the Teneguía eruption, 2 fishermen died), so one should approach the wind to the back to be possible and with a LEL gas meter to control the H2S, O2, CO2 and CH4..... and safely enter.

Finally, we are going to the swarm, reactivate again, with the latter 3.7 definitely returns to the load despite a small break last night, which leaves us that tonight will be more scrambled and what is not if it is in power max or it's still going up more... we'll see in the next 24-48 h.

es2021tpmev 19:56:43 06/10/2021 18:56:43-17.8236 37 km M 3.7 mbLg II-III SW VILLA DE MAZO. ILP

The line marking released seismic energies accumulated is exponential today and has been set with a more or less constant slope in the past 3 days, releasing a whopping 180 MWh. in 3 days... at 60 MWh day.. like a 4,4 magnitude Earthquake each of these 3 days, tremendous..

This indicates that we are reaching a high point where the volcano has reached its maximum speed in energy emission.. or that it is no longer reactivated, hopefully now no longer uploads and limits to being defunded or turning off... don't reactivate anymore (Enrique).

https://www.volcanodiscovery.com/la-palma-earthquakes.html#quakeTable

As for the volcano I see it getting more ash and it's finer, it's increasing the shredding of it at the output, which can lead to an evolution in the magma, which is changing its composition towards a magma surely more silicone, increasing its viscosity and explosiveness... to be confirmed by taking new samples and chemical and mineralogical analysis.

Tomorrow more... what a night awaits us... the volcano to its own that will remain more or less stable with a lot of noise, explosions and ash... and the swarm giving the can with more tremors, may have some major shaking in around 4, -. energy has.- and not ruling out that you could open a new mouth near the current cone less than 500 m, at most 1 km and in a fan in NNW directions - NW. Cheer up!! and a greeting. (Enrique)
