13/09/2020 - 19:15h Canary Islands. - ACTIVITY IN THE PALM. - NOISES, SHAKERS, BEATS AND LOTS OF GAS. - THE VOLCANO IS REACTING. - I didn't want to get to this point, but it's been a month that the volcano is with a new process, which is a soft reactivation in all order, but no longer without fear of being wrong it's a reactivation. In the 2022 depth chart you can clearly see the increase in sustained activity at 9-13km that is causing magma to migrate through that area.

These last few days, especially the last few hours are being busier than expected, in addition to inhaling SO2 teal gases throughout the Aridane Valley, people feel like they are rolling stones and punches, as well as vibrations and shaking s in several areas of Los Llanos, Las Manchas and The March. Some even come to describe it as an actual "underground storm." In fact, some have heard "jets" or pressurized gas spills from high emissions from the fumes that have dragged some ash nearby, no less.

I leave you a fragment of the following report from a resident in La Laguna tonight:

"Hi Enrique!
I live in La Laguna and for a few weeks the changes have been increasing. From the total silence of the night. To very nervous or very clingy animals.
But there are two special things.
Last week a painting fell off the wall (it's been hanging there for 6 years.. even during the volcano) and now. Tonight. Absolute silence outside and I just noticed a loud bang. Like a closet fell under me (like on a floor). At 0.30 hours later.... almost two hours (!!!! Hasn't had that since the eruption) shaking back and forth and strange noises too. Like a submarine or something.
The tremor was pretty weird too. Because once I only felt it below the back of my knees.... After the 8th time (like a train passed under me) I stopped counting. "

So, there is NO new eruption, but if volcanic activity is coming back and should be watched more intensely, since a year ago we went to yellow traffic light after the meeting of the PEVOLCA. Here is the link to Post 406 from this very space on September 13, 2021.

https://www.facebook.com/.../pfbid0Sa63x...Ks3EG14bUk...

The PEVOLCA has updated the information on gases in its latest report of the Report of 09/09/2020 -14:00h and, which I have not been able to find at the moment, only chronicles.

YELLOW SEMAPH LIGHT
And the traffic light is still yellow, people very nervous, noticing and hearing things, seeing again ash on the leaves of plants and even sweeping ash off their whips (possibly dragged by the wind or the "jets" or pressuriz leaks gas ads they say they heard tonight. Also rumors are coming, (Unconfirmed) and what worries me most is that a new crack has been located between the Remo and port Naos, where a lot of gases come out. That crack could be a gas fireplace and the previous point most likely has in case the magma rises, and which by the way is just below pushing in a swarm that forces it to move SW from the Cumbre Old Reservoir towards THE Paddle

In the graph of earthquakes with the depth it is noticed that the area between 9 and 13 km is more active, which is reflected in the largest number of earthquakes these past days and which is starting to be clearly noticed in the graph of the released seismic energy accumulated (blue line) and you can see that it no longer stops, but has a continuous release of energy indicating that there is a process going on for almost a month.

THERE IS NO SHAKING:
The sea has waves of several meters, generating quite a lot of noise, which affects the seismographers, but there is no tremor at the moment, the last peak of the same is a 7.6 telesism, and it is luckily still low.

With all of this you can NOT be assured that there will be a resounding eruption, it is a reactivation and a process that has been squeezing for a month, and all indicating that it will continue to squeeze. The odds are actually between 10 and 20%.

What we have to think now is whether it will hold the ground and stop or if on the contrary it will start rising seismicity, gases and deformation and come back out as it did a year ago. Nobody knows this.

At the moment, deformation, gases and field data are missing, so I do not rule out that there are more conclusive data. One of them would be a reboot in the He3/He4 relationship that would indicate a new magmatic intrusion and that would explain what's going on.

Also in some liars of markets, bars, institutes and social networks as they would say in Madrid, they are saying that the UE has returned to the island today, for this possible volcano reactivation. The rumor that is to be officially confirmed and that to be confirmed would indicate that there is more information that is made public, which no one misses you with that mania to cover, hide, oblivious or not publish information that is sensitive and for tourism.

And a little more, I end with the last, you see noises that look like volcanic glissandes generated by the noise that arises when there is a depressurization of fluids and gases in a narrow rock passage and which are clearly marked on the spectrum s could even explain the jets or gas splashes and some of the noises heard this afternoon. 13&typeFO=2&typeSP=1&station=PA01&time=12-13

Much encouragement, now we have to see how the state of the volcanic system evolves, at the moment it is NOT going to a clear eruption, it is a process that is maintained, it is made way, but it does not cease. The good news is that it doesn't accelerate any more (more seismicity), but it doesn't slow down either, so we're at a waiting compass to see what it does. (Enrique)

PS: Have there been successive eruptions in the Canary Islands in the year before? , The answer is yes, in fact in Tenerife where there were 4 in less than two years in a row, in Tenerife: First we had the triple eruption of 1704-1705 where they were followed and then every year and little that of 1706.

- Seven Fountains (6 days) from 12/31/1704 to 05/01/1705
- Volcano de Fasnia (11 days) from 05/01/1705 to 16/01/175
- Arafo Volcano (54 days) from 02/02/1705 to 27/03/1705
- Trevejos Volcano or Arenas Black, which destroyed Garachico in 1706 and lasted 40 days from 05/05/1706 to 13/06/1706

Dead turtle doves in a garage in Puerto Naos with oxygen levels of 13%
Lethal gases prevent the definitive return to this tourist center a year later

— Scientists insist that "there is volcanic danger" in Cumbre Vieja and do not rule out "reactivations"

The main tourist center in the western area of ​​La Palma , Puerto Naos , has been closed since September 19, 2021 due to the presence of gases of volcanic origin, which affects the 1,400 people registered in this enclave who are It allows them to access in a controlled way to carry out maintenance tasks and removal of belongings.

The first signs of deformation of the terrain of the eruptive process in La Palma were detected a year ago this Tuesday

KNOW MORE
Empty avenues, dry plants on balconies and open windows with curtains blowing in the wind is the image left by this privileged enclave before the eruption and ghost today, in which only the warnings of the gas measuring beacons and the engine are heard. desalination plants installed nearby.

During the visit organized by the Cabildo de La Palma to Puerto Naos, the technicians found two dead turtle doves inside a garage in which the oxygen levels barely exceeded 13%. "If a person enters that garage, within minutes he would lose consciousness and then his life," said Rafael García, security and emergency technician at the Insular Operational Coordination Center (Cecopin), dependent on the Cabildo.

The desperation of the residents and business owners of Puerto Naos has been increasing over the months, and there are twelve, so some have organized to hold a rally at the entrance to the center on the eighteenth of this month, with the aim of forcing the administration to provide more solutions.

Carmen Castro is one of these people who, in addition to being part of the Puerto Naos Entrepreneurs Association, will attend the demonstration, since, although she knows that the CO2 detected in her business can be lethal, she believes that more is needed information and certainty on the part of political leaders.

"I will come to support the neighbors who want more transparency, who want to be able to access more often to ventilate and see how their properties are," Castro explained.

On the other hand, this neighbor and owner does not support certain sectors that deny the existence or the dangers of the CO2 concentrations that are detected in Puerto Naos and has stated that "if things get ugly, other businessmen and I will leave in that instant".

To explain the current situation of Puerto Naos and La Bombilla, the other nucleus evacuated by the gases, a meeting has been called this Tuesday, September 13, in which members of the scientific community and politicians of the island administration will try to resolve the doubts of affected neighbors who so require.

According to Rafael García, Cecopin's security and emergency technician, the measurements carried out this Monday morning have shown very low oxygen data outside, less than 18%, due to the fact that the CO2 that emanates from the subsoil displaces the breathable air.

During the visit organized by the Cabildo to Puerto Naos, the technicians found two dead turtle doves inside a garage in which the oxygen levels barely exceeded 13%. “If a person enters that garage, he would lose consciousness in minutes and then his life,” García has sentenced.

Volcanic danger” in La Palma
A report from the Cabildo de La Palma states that "some volcanic dangers persist, without being able to rule out future reactivations."

The Cumbre Vieja is about to celebrate a year since it erupted on the island of La Palma and every day we were telling everything that happened for weeks.

Since the eruption ended on December 25 , the volcano is in a post-eruptive phase. With all precautions. A report from the Cabildo de La Palma states that it advises keeping the area of ​​Puerto Naos and La Bombilla "evict" for "a precautionary principle".

tense calm situation

The update report on the volcanic activity of the Cumbre Vieja , dated September 9 and released this Sunday, indicates that " since December 13, the post-eruptive phase continues , in which some volcanic hazards persist, without be possible to rule out future reactivations”, according to the Cabildo de La Palma.

In nature, nothing is ruled out, that's why experts are more vigilant. “There is no presence of volcanic tremor in the seismic signals. Surface seismicity and intermediate depth continue to be located . Seismicity related to the movement of volcanic fluids continues. There are no significant surface deformations of the terrain related to magmatic activity”, the report explains.

The danger continues to exist, since the high temperatures and the instabilities of the terrain in the volcanic cone remain, in addition to the lava flows, " thereby persisting its danger ".

“Currently, an instrumental monitoring network is operational to continuously record the concentrations of CO2 (carbon dioxide) in the ambient air, both inside and outside buildings, in the population centers of Puerto Naos and La Bombilla, which currently integrates more than 20 sensors of different nature”, he adds, areas that are already on pre-alert in case it is necessary to take other measures.

“Both in the towns of Puerto Naos and La Bombilla, as long as the CO2 levels are not within the exposure limits that are considered usual for the general population, for a principle of precaution, prudence and prevention, it is advisable to keep the area vacated . , allowing access only for the performance of work activity, following the protocols established by the occupational risk services”, they add.

The alert remains at the yellow level, which means 'fair', in a table of five levels: good, fair, unfavorable, very unfavorable and extremely unfavorable.

THOSE DAMNIFIED BY THE LA PALMA VOLCANO DENOUNCE THAT "THE MANAGEMENT HAS BEEN A DISASTER"
They will demonstrate, a year later, still waiting for the publicized aid

A year later, the victims of the La Palma volcano continue to suffer at this time from absolute uncertainty about their future, and most of them are still waiting to receive the promised aid for the reconstruction of their homes and businesses (... ).
By A. RAMÍREZ FOR THE CANARY ISLANDS-WEEKLY.ORG.-



As could be foreseen, due to the background of other natural catastrophes, a year later the victims of the La Palma volcano continue to suffer absolute uncertainty about their future, and most of them are still waiting for receive the aid promised to rebuild their homes and businesses.

The victims commemorate the anniversary with a demonstration, which will take place next Monday, September 19, in Los Llanos de Aridane, to criticize the "disastrous management" of the emergency.



The president of the Platform of People Affected by the Cumbre Vieja Volcano, Juan Fernando Pérez Martín , denounces that the people of La Palma have been forgotten by public administrations .



"The management of the aid, of all of them, has been a disaster. Such attitudes that lead those affected to a dead end cannot be tolerated," he criticizes.



Under the motto "Make silence a cry ," the march will begin on Monday at 7:30 p.m. at the Eusebio Barreto institute and will continue to the Plaza de España, in Los Llanos de Aridane.



"They have wasted precious time on initiatives that only lead to nowhere," Pérez Martín denounces in the statement that accompanies the call for the demonstration.



The Platform demands from the authorities a "more forceful and more empathetic" attention and "not settle in the complacency that everything is perfect."

Imminent eruption”: why the authorities did not evacuate those affected by the La Palma volcano sooner

The National Geographic Institute (IGN) warned that the eruption "was imminent" a day before and the traffic light remained yellow. The scientific warnings that raised an orange traffic light scenario were ignored by the emergency management. Predicting the exact moment of an eruption is impossible.

enerifeSince the 16th century there have been at least fourteen volcanic eruptions, half have been in La Palma and all have ended up in the sea. The Canary Islands are located on a passive edge of the African continent subjected to many tensions due to movement with respect to Europe and the American continent. These tensions accumulate at the edge and move to the Canary Islands, which joins a "mantle plume" that has a continuous rise of magma from the mantle (at depths greater than thirty kilometers) to the Earth's surface. It has been explained by the National Geographic Institute (IGN).


The person in charge of volcanic surveillance in La Palma, María José Blanco, appeared at the reconstruction commission of La Palma in the Parliament of the Canary Islands with a very didactic presentation on what happened on the island. When distensive periods occur, with forces that favor the rise of magma, we can have volcanic eruptions. From October 2017 to June 2021, there were seven seismic swarms in the area of the last eruption that were brought to the attention of emergency managers by the National Geographic Institute, "so that they take the appropriate measures," explained María José White in parliamentary seat.

September 13, 2021: the eruption of La Palma gave signs of being imminent for the first time
On September 13, -six days before the eruption-, the earth was shaken with a huge number of earthquakes. "We went from more than twenty kilometers deep to twelve kilometers, from those depths, the most normal thing is that the eruptions can end on the surface," explains María José Blanco, responsible for the volcanic surveillance of La Palma at the IGN. In addition, an enormous deformation also occurred. Two days before the start of the eruption, 24 centimeters of deformation accumulated vertically and to the south. "Think of the energy it takes to lift more than twenty kilometers thick twenty centimeters upwards," explains Blanco.

September 18, 2021: the eruption was imminent, PEVOLCA maintained the yellow traffic light against scientific criteria
Despite the clear signs of an eruption, the emergency management decided to maintain the yellow level and not start evacuations. “In the scientific committee on the 18th, it was said that the eruption is imminent. Look for this term in PEVOLCA, and you will know what it corresponds to. Eruption imminent”, explains María José Blanco. By pronouncing these words, the scientist opened a debate about whether the authorities should have reacted earlier and evacuated the areas in time. The scientific committee had a clear criterion and suggested going up to the orange level, however, the PEVOLCA management maintained the yellow level and decided not to evacuate the neighbors yet.

September 19, 2021: the Earth opens on La Palma and the eruption begins at several points simultaneously
On the morning of September 19, the mayor of Barlovento, north of La Palma, received a call to activate his local Police before the imminence of the eruption, however, not a single person had been evacuated yet. “That day in the morning they called us because the eruption was imminent, we went to Los Llanos and at twelve noon they told us that the eruption was not going to happen that day. Two or three hours later the volcano erupted”, explains Jacob Quadri, pointing out how difficult it is to predict the exact moment. Since the previous day, the authorities had enough information to make the decision to start preventive evacuations in the area, as happened in La Restinga. Nevertheless,To say the moment in which an eruption is going to take place is impossible”, explains María José Blanco. The information available in the Canary Islands about volcanoes is not as high as in other areas of the world with a much higher eruptive frequency, therefore, it is much more difficult to obtain accurate predictions. “It is very easy to predict what is going to happen during the entire eruption, but knowing what is going to happen tomorrow is impossible. It's as if you told me: in summer it's going to be hot, yes, but what about tomorrow?” explains Blanco. "Short-term prediction was impossible, totally impossible," she concludes. According to Blanco, it was also not possible to know the exact place because the entire Cumbre Vieja ridge had possibilities.

Around three in the afternoon, the Earth opened in Cabeza de Vaca through two fissures with more than six simultaneous mouths that began to build very fast volcanic cones. Lava fountains that exceeded 600 meters in height were soon reached. The eruptive column reached 8,000 meters and kept the island totally cut off by air for weeks. The eruption severely affected 2,329 people and forced 7,000 to evacuate. It destroyed 1,646 buildings: 1,345 homes, 75 industries, 44 hotel and commercial facilities, and 16 public infrastructures. The lava swallowed 74 kilometers of highway and 370 hectares of crops, according to official data from the National Geographic Institute.

"Nothing indicates a temporary space," said the president of the Cabildo, Mariano Hernández, on the same day of the eruption.
On Sunday, September 19, even with the traffic light at a yellow level, Pevolca gave an account of its daily report at 2:00 p.m. in which an increase in seismic activity was reported, but that "nothing indicates a temporary space" in which could start an eruption, in the words of the president of the Cabildo, Mariano Hernández, and affirmed that "we are not yet at the moment for the scientific committee itself to pronounce on a change in level" and "the yellow level is maintained", with the preventive evacuation of dependent persons. The technical director of Pevolca, Miguel Ángel Morcuende, reported "a very clear increase in activity" and the activation of the necessary measures for the evacuation of people.

At 3:13 p.m. on Sunday, September 19, the volcano erupted and the traffic light went from yellow to red, without going through the orange level, a maximum alert situation. Initiation of a preventive evacuation when indicated. According to the same traffic light, the red level indicates “Immediate and urgent evacuation. All people must collaborate with the authorities for the mandatory evacuation." As revealed by a close friend of the president of the Cabildo in the program Confessions, of Televisión Canaria, Mariano Hernández called him the day of the eruption warning him that the eruption was imminent . " He tells me look, go home, the volcano is about to explode, tell your family," his friend revealed on public television.
