Geologists do not rule out the opening of new eruptive mouths
José Luis Barrera explained that right now the laundry is more fluid and is coming out at a higher temperature than the first days, when scientists pointed out that it was more than 1,000 degrees Celsius in temperature

EUROPA PRESS


The geologist of the Illustrious College of Geologists José Luis Barrera does not rule out that the Cumbre Vieja volcano in La Palma could open new eruptions, in addition to the last one that has been registered during the early hours of this Friday.

Barrera has explained in statements to Europa Press that right now the laundry is more fluid and is coming out at a higher temperature than the first days, when scientists pointed out that it was more than 1,000 degrees Celsius in temperature.




In addition, it specifies that the first emissions were more explosive as a result of the gases being "opening the emission conduit", by way of cleaning while now, although the explosions continue, they are not as frequent and intense as those of the first days . This is because the emission conduit is cleaner and the lava comes out "less polluted, more fluid and from there it goes directly to the sea."

At the same time, he believes that the new laundry could join the initial one. But he warns that now the "old" stream is beginning to widen into the ground and if this new lava is added to it "it would be bad" for the current emergency, since it could affect new infrastructure and assets that were not previously. .

In this way, it affects that when the lava falls into the sea in a cascade it will cool "abruptly" when in contact with the sea and it will be possible to form "another new extension of the coastline"

"It is possible that more mouths can be opened, but seismicity parameters must be monitored," warns the geologist who points out the importance of monitoring the depth at which these seismic movements, now at about 10 or 14 kilometers deep.

Finally, he points out regarding the stoppages of volcanic activity, indicating that these are the "pulses typical of the eruption", that "it does not work like an open tap", but rather that it is the gases that drag the lava to the surface to expel it. .

As reported by the National Geographic Institute (IGN), in the last 24 hours there have been twelve earthquakes in the south of the island, in the vicinity of the volcanic eruption in progress. It also confirms that the hypocenters are located between 10-14 kilometers deep in the same area where the reactivation began on September 11.

At the moment, two of the earthquakes were perceived by the population. The strongest, with a maximum intensity of III in the epicentral area and corresponds to an earthquake of magnitude 3.5 mbLg that was registered at 8:30 p.m. this Thursday.

During the morning of Thursday the mean amplitude of volcanic tremor remained stable and in the range of usual values ​​of all these days. However, as of 6:00 p.m., it began to increase gradually until reaching in the last hours values ​​similar to those that arrived during the first eruptive days.

In any case, the monitoring of the network of permanent stations indicates that the island is returning to stability in the deformations.

The volcano opens two new mouths of emission and generates a new flow
The changing wind and 'unfavorable weather conditions' will worsen air quality in the valley, where high levels of sulfur dioxide are already recorded


The changing wind and "unfavorable weather conditions" will worsen air quality in the valley, where high levels of sulfur dioxide are already recorded. The Cumbre Vieja eruption has not one, but two new mouths active since early Friday morning. They are about 15 meters from each other on the northwest face of the cone and at a distance of about 600 from the crater. Starting at 2.30 am on Thursday, they expel two separate "very fluid" lava flows that advance towards the "primal flow", as defined by the director of the Canary Islands Volcanic Emergency Plan (Pevolca), Miguel Ángel Morcuende.

At the moment, that new stream runs about 450 meters northwest of the first and is moving fast aided by the topography. At 10:00 am on Friday, he surpassed the LP-212 highway, in the Aridane Valley, and "was looking to join the first," explained the person in charge of the emergency plan.

The original wash that Morcuende alludes to forked in two a week ago to surround the Todoque mountain and it was the one on the south side that reached the sea at 11 pm on Tuesday. However, although it is channeled almost all the way, in some areas it has widened and has destroyed new properties (the number of damaged buildings now exceeds a thousand). In addition, in its final section it has separated again and has generated a new river of lava that could flow into the ocean about 200 meters from the first.


With the two of this Wednesday, there are already seven active emitting centers of the eruption: there are three more inside the crater and another two on the side of the cone. Blanco, who is head of the Geophysical Center in the Canary Islands of the National Geographic Institute, affirms that the Cumbre Vieja volcano has already expelled 80 million cubic meters of magma, double that of Teneguía (1971) in a third of the time.

The tremor, which is a type of earthquake characteristic of volcanoes, increased from the early hours of Friday, according to the spokesperson for the scientific committee, who stressed that seismicity continues close to what it was in the first days, being detected in the Last days dozens of earthquakes of intensity 3-4 whose epicenter is located 10 or 15 kilometers deep. All this suggests that the Cumbre Vieja is very active. "The fissure eruption continues and the morphology of the cone is constantly changing," he added.

The plume - the toxic cloud product of the gases released by the entry of lava into the sea - evolved this Thursday towards the north-west of the island, although the forecast was that it would turn last night, pushed by the north wind, and move towards the southwest of the island. "It is not ruled out that fine ash may reach the island of Hierro", advanced the geologist, who pointed out that current meteorological conditions, with high stability of the atmosphere in low layers, together with weak winds, are "unfavorable" from the point view of air quality.
The spokeswoman for the scientific committee specified that in the measurements carried out this Wednesday, high values ​​of sulfur dioxide were obtained in the stations of Tazacorte and Los Llanos. In the first municipality, the daily average was 219 micrograms per cubic meter, when the maximum is 125 (between 7 and 10 in the morning they reached 350, that is, almost triple).

In Los Llanos, the average was 198 micrograms per cubic meter, although the highest rates were recorded between two and four in the afternoon on Wednesday. Fortunately, the geologist noted, no hydrogen sulfide was detected at any of the stations. He also explained that the ratio of carbon dioxide and sulfur dioxide in the plume reveals that the lava comes from a deep magmatic system.
The Pevolca maintains the confinement measures in four neighborhoods of Tazacorte and the recommendations to use FFP2 masks outdoors in the Aridane Valley. The director of the emergency plan maintains that the air quality on La Palma continues to be "good" and recalls that the volcano affects 8% of the island's surface. "We have a problem centered in the Aridane Valley, but the rest are leading a normal life and we must transmit it," emphasizes Morcuende, who pointed out that, even so, the air in the valley is "within healthy and breathable limits." “It is obvious that the closer we are, the worse the quality will be; It cannot be the same in Los Llanos as it is in Barlovento (north of the island) ”, added the head of Pevolca.

The column of smoke and gases that the volcano itself releases, and which has forced air traffic to be interrupted this week, already reaches 6,000 meters of altitude -1,000 more than on Wednesday- and that the rate of sulfur dioxide emission towards the The atmosphere is, according to the geologist, high: 8,700 tons per day.

The delta formed by the entry of lava into the sea, which scientists call fajana, now reaches 27 hectares and has penetrated 475 meters into the sea, reaching a depth of 30 meters. And it grows constantly because the contribution of magma does not stop.

Latest update courtesy of Enrique.


01/10/2021 h Canary Islands.- LA PALMA ISLAND ERUPTION.- THIRD NEW MOUTH COLADES THIS MORNING.- The truth is that luck has been made and the mouth lava that opened yesterday have mostly incorporated into the lowering laavic canal into the sea, which is great news, and it doesn't seem to affect more houses, except for an overflow going north.

That overflow doesn't concern me in view of the other new flow coming out this morning from the mouth 3 to 400 m to the NW of the volcanic cone that has gone further north and whose end has stopped at a site at the one who looks like split in two. One arm would return north of the old flow, alongside the overflow of yesterday's flow but the other arm overflows northward, which would be a problem as it would head to the main street of Tajuya and from there to the ravine crossing the Pedregal and La Laguna.

Now what we're most interested in is that these new flows go into the teardrop and don't cause more destruction, it would be the best of all options, and end up in the delta. And delta, I let you enjoy the pictures, everything that ends there doesn't hurt elsewhere..


Let's see what the flow 7 does, which is the most concern me so far, I don't have more data. (Enrique).

''01/10/2021 h Canary Islands.- LA PALMA ISLAND ERUPTION.- THE ENJOY-VOLCANICO SISMO-ADVANCE, PRESURIZE AND THE EARTHQUAKES ARE EVERY TIME STRONGER.- This second magma intrusion about 10 km deep that is occurring under the volcano of Old Summit in the Palm, attempts to make way toward the surface by breaking the rock in depth by pressing and pressing the rock, so that it ′′ crushes ′′ as a plank that bends before departing. The rock does the same thing and when part, the ′′ crack ′′ is the fattest and is a broken Earthquake, after which the system loses pressure and the magma advances generating less seismicity if it finds no resistance. I leave you the last 5 located.

Therefore, after a broken Earthquake, (rock) we have a time or time where seismicity goes down, when depressurizing, and there are weak signs of depressurizing fluids (such as those that were located when the volcano a few days ago) until pressurized again, the moment seismicity repounded and earthquakes begin to rise in intensity. As you get closer to the surface, the magnitude is often raised and more noticeable to be more superficial.

With the noise of the volcano, the tremor, small earthquakes are very hard to ′′ hear ′′ by seismographers and can't be located unless you have special seismic arrays-like devices, which allow more Events to be located. I know there are some installed, both by IGN and Involcan. These small earthquakes are the most interesting in volcanoes because they give us very accurate information about what is happening inside the volcano.

With all this, seismicity will follow and as it goes up, we will see if it follows the same path as the first intrusion or choose another path, so we must be very aware of seismicity and deformation, which will indicate us as progress all that magma that's on the way to the surface.

Finally comment on the graphic of released seismic energy accumulated or cantor function, also known as the devil's staircase and we see how it starts to get more inclined or uphill, indicating that the system emits more energy or is entering a release phase of more energy. (Enrique).

EDITED: There was just a 2.8 to 39 km Earthquake, I guess they'll check it out as this wouldn't indicate anything good, rather, clearing your throat to send even more magma upwards... let's go see what they put in the review.. (Enrique)

OT the islands near Sicily have been put on yellow alert as a dormant Volcano for the past 133 has suddenly started emitting a plume .


''Civil protection: yellow alert for the volcano of the island of Vulcano
Strengthen monitoring and surveillance activities

Passing alert YELLOW Vulcano
The Civil Protection Department has ordered the transition to the "yellow" alert level for the island of Vulcano.

In agreement with the civil protection structure of the Sicilian Region and with the unanimous opinion of the Commission for the prediction and prevention of major risks, the Department has assessed that the significant variations of various parameters of volcanic monitoring, detected in recent weeks by the National Institute of Geophysics and Volcanology-INGV and the Institute for Electromagnetic Detection of the Environment CNR-IREA, require some additional measures and initiatives for risk management on the island.

In particular, the "yellow" alert level determines, among other things, the strengthening of volcanic monitoring and surveillance activities (also with the possible involvement of other centers of expertise in addition to INGV and CNR-IREA which ordinarily deal with it ), a constant information link between the scientific community and the other components and operational structures of the National Civil Protection Service, the updating of civil protection plans, a widespread information activity to the resident population on the island and to tourists, with specific reference to raising the level of risk. The civil protection structures of the Sicilian Regional Authority and the Municipality of Lipari have already been activated in this sense to take all the necessary initiatives.

"Thanks to the efficient integration of the scientific community into the civil protection system, today we can count on volcanic monitoring and surveillance systems that allow us to closely follow the evolution of the activity of our active volcanoes", says Fabrizio Curcio, Head of the Department of Civil Protection. “And that's what we're doing on Vulcan. With the "yellow" alert level (which can be followed by orange and red or the return to the ordinary "green" level) it is very important that there is full awareness of the risk, without alarmism, but with great responsibility. "

The island of Vulcano already ordinarily presents a widespread situation of risk for the population connected above all to fumaroles rich in gas and with high temperatures, but at this stage it must be remembered that they can intensify and extend over larger areas and therefore the danger is greater.

Any further significant changes in the situation will be promptly communicated.''

The magma eliminates the prestigious surfing area of ​​Guirres
It is an area recognized and enjoyed by many surfers ", lamented the Spanish Federation of this sport


Upon reaching the sea, the magma from the erupting volcano on the Spanish island of La Palma has eliminated "any vestige of the Guirres area , an area recognized and enjoyed by many surfers," lamented the Spanish Federation of this sport.

"The 29th will be remembered as a sad day because we are witnessing the disappearance of a natural sports facility that brought so many benefits to the surfing community , " the agency said in a statement.

The president of the Canarian Federation, Ángel Lobo, specifies in the note that the Guirres area "had a great quality of waves, with multiple peaks" and speaks of it as "a magical place."

In the five championships that were held in it, he adds, "things were lived that were not experienced in others", with the local society turned "to enjoy and live" the tests.

Aníbal Pino, president of the local surf club 'Revolcón', shares his sadness at an event that "has totally convulsed" the work of his sports entity.

"The landscape has been transformed and what we are experiencing is hell," he said.

The lava expelled by the volcano has reclaimed 367.3 hectares from the sea, according to the latest satellite calculation

A new mouth has been opened in the La Palma volcano on the morning of this Monday, specifically, at 10:30 a.m., as reported a few minutes ago by the Canary Islands Volcanology Institute (Involcan).

Thus, as can be seen in a video shared by the researchers themselves in view of the drone, it is appreciated how the new emission source is already expelling lava as well as gases, adding to the many other cracks that have opened in recent days after the eruption of this volcano in Cumbre Vieja on September 19.


Cumbre vieja opens two other mouths and confines 3,500 people ...
There are four active mouths, after the appearance of another two outbreaks whose tail ...

These are comments from the Facebook page of Volcanoes and Volcanism.

Interesting to read another persons perspective on the eruption.

''Situation on La Palma is getting worse.
The lockdown due to the high concentration of toxic gases has been extended and now also applies to parts of Los Llanos and El Paso.
The last water pipeline that still worked in the areas around the outbreak has now also been destroyed and is currently attempting to organize a mobile desalination plant in order not only to supply drinking water to people and animals, but also to water banana platages, which are a very big economic factor of the island.
The number of earthquakes is also increasing significantly. Much of the quakes are still recorded south of the eruption site at a depth of 9-13 kilometers. This means that there is currently no cause for concern that another eruption occurs a few kilometers south, but it shows that a large amount of magma continues to rise.
The entire cone of the volcano seems to continue to heat up. Hot gases are pouring out of the whole cone. In my opinion, it's only a matter of time before more parts of the cone will collapse should activity continue at this intensity.''

Latest update courtesy of Enrique.


02/10/2021 h Canary Islands.- LA PALMA ISLAND ERUPTION.- NORTH COLADA PREVIEW EARRINGS (NUMBER 7) AND IF IT WILL BE TOGETHER WITH THE LAVIC OR CHANNEL FOLLOWING THROUGH THE NORTH OF THE OLD.-

Just updated with images from Canary TV where the flow 7 was standing in parallel to the north area of the flow field from previous days an hour or so ago.

In the upper area of the lavico channel, it is developing a roof, and it is starting to cover, forming a lava tube, there can be no better news, as it stabilizes and avoids overflow, the problem is that the lava is very hot and low fluid inside and if it's plugged, a mouth may appear in the path of this formed tube.

What will happen in the next few hours is important as the lava flow coming down from flow 7 has two options, follow parallel north of old flow or join the lavic canal.

Initially if you join the lavic canal seems like the best choice, but by the low lava, very hot and very liquid, which could alter course by entering this flow . We'll see what happens. (Enrique)

As far as the energy curve continues to rise, and not just little, more seismic Events have been located and the result is that volcanic energy continues to rise exponential since the second shift began. What does this mean?, basically that tonight has been taken a break and this afternoon will surely return to load with many earthquakes or few more intense.. We'll see what happens (Enrique).

There are no signs that the La Palma volcano eruption is going to end anytime soon
The depletion of magma or the emission of gases is not appreciated

The seismography specialist of the National Geographic Institute (IGN), Itahiza Domínguez, has affirmed, regarding how long the volcanic eruption of Cumbre Vieja, in La Palma , will last , that there are no signs of magma depletion or in the emission of gases from the volcano therefore, there is no indication that it will end any time soon.

Domínguez, in statements to Efe, points out, however, that it is too early to know how long the eruption may last since it is necessary to analyze more data "and even so it is not clear that it can be predicted when it will end."

“We will see it over time. It is still too early to know if the eruption will last a few weeks or much longer ”, adds the specialist.

Regarding the evolution of this volcanic process , Domínguez affirms that it continues as yesterday with a main cone that emits pyroclastic and ash clouds from various points.

Remember that these ashes are creating columns up to 6,000 or 7,000 meters high as yesterday, although today, according to information provided by the IGN, the height has been lowered to about 4,000 meters.

The secondary point, the secondary cone, on one flank of the main one, continues to emit a lava flow which is the one that reached the sea while the two new sources, which were opened yesterday 600 meters from the main one, emit a fairly fluid flow.

Domínguez indicates that, according to the information available to them, this new stream is connecting with the main stream, although he warns that this may change at any time because they are areas of complex orography.

"The models could say that it goes the other way depending on the viscosity, temperature ... the lavas can be cooled and create barriers that make it flow in another direction. We have to wait and continue pending the information and the predictive models that can be made ”, he says.

The expert explains that the volcanic cone can change little by little because it emits a significant amount of material and collapses because it has no stability and points out that there was a small explosion yesterday and now it is emitting ash again.

He adds that it is possible that part of the cone may end up detaching but it is difficult for it to collapse completely, although it indicates that as long as the safety distance is maintained "there should be no greater danger" if it occurs.

The IGN technician affirms that in these strombolian eruptions new emission points can be originated near the main mouths and he does not rule out that new ones may arise.

What if you rule out with the current information they have, is that a new emission zone appears in the Fuencaliente area due to deep seismic activity.

"It is not a very dense swarm" indicates the specialist, who points out that it is being studied whether the seismicity is related to a magma refeeding process at a greater depth, although, if this were the case, it would continue to come out through the main mouths.

Also, he explains, it could be an adjustment of the magmatic system since the pressures are changing and the material that is expelled comes from very low where there may be an overpressure but that will be evaluated over time.

For now, it is affecting the magmatic system that is open and that is releasing its pressure through the emission of the main crater.

Latest update courtesy of Enrique.

02/10/2021 h Canary Islands.- PALM ISLAND ERUPTION.- SINGER FUNCTION RELEASED SYSMIC ENERGY RELEASED ACCUMULATED OR STAIR OF THE DEVIL MARKS US THE STEP OF THE MAGMA THAT CLIMS. - Nature surprises us many times and when a natural phenomenon can be parameterized into something logical like the earthquakes we're having in the volcano behavior, it's tremendous. Nature is often foreseeable contrary to what it may seem and a volcanic eruption can be explained with science.

https://es.wikipedia.org/wiki/Funci%C3%B3n_de_Cantor?fbclid=IwAR2wMicQ6CbjyKCsiWz-aO8epU6uY0cODKbas7auf93R0DCLFIFfSjdRNtk

This graphic tells us that the volcano is increasing its seismic energy emission over time so that every day releases more energy. The explanation for this is the entry again magma
pressurizes inside the volcano that is recharging your batteries or inflating like a balloon in depth and as it closes to the surface, that huge mass of magma, more energy releases.

I'm going to remember something I wrote 10 years ago on the subject:

′′ THE DEVIL'S STAIR, this is known as the form of the curve of freed energies accumulated on Iron Island from September 19, 2011 to today (it was a September 27th). In volcanology it is used because its steps are becoming higher indicating a volcanic process reactivating. It is also called the Cantor function and it has infinite steppings of height and variable width, but they follow a pattern (Enrique)."

That September 27th we didn't know that Iron thing was going to end in an eruption, but we are giving very clear signs of where I was going. If we look at the last earthquakes 3 +, today it has had a very interesting sequence and the pylon hammer works with more energy in every seismic blow (the PICAPICA) and I think it's not over, it hasn't broken what's at 9-11 km... So we will have more, a 3.7-3.8 or more surely before midnight.... what a landscape.

On September 27, 2011, even the newspapers echoed the matter. (Enrique)

http://www.diariodeavisos.com/2011/09/nuevos-movimientos-de-38-y-36-grados-en-el-hierro/?fbclid=IwAR3IuZ09PTU-UplntxfaMH7dN30-4JxOxtgb2SPzfxH2n9OTCqTNANRh1Ow

If you feel it, it would be nice if you put it in remarks if you notice it coming from the side or from the bottom, it will tell you where you have it... and if, if it comes from under you will go from top to bottom. Don't worry about it, when you break that at 9-11 km you will have to climb causing new earthquakes and surely pressurizing in the next few days and in theory the most likely area is that that magma will go to the eruptive zone that is the least cost you to get out .. The second option would be to continue to rise vertically and do so by its own Summit area in the Nambroque area at the highest end of the Old Summit.

We'll see what happens. (Enrique)

Comments from Volcano y ciencia hoy


Hello, Enrique. One question (or to whoever knows): Why do you have to ′′ review ′′ the magnitude of earthquakes? I mean, what's the reason that the first measure isn't always valid?

Gisela Burunat There's an automatic system that locates them to give a quick system. Then you have to reprocess the data manually to better tune that calculus into seasons that capture it well and remove the worst ones that capture it for a better result. So some should go up and others should go down... incomprehensibly with IGN they only go down and when they see it shows a lot, they come back up. I really don't understand those IGN reviews much. (Enrique)



Mike Hayward
We need to break the chair is what keeps it there seismology and volcanology, play in the same direction as low frequency movements or VT marks us where the magma moves, tell that the Great Earthquakes can not be predicted but if you can tell that due to precursor movements anticipate you to a big one, as some large earthquakes precede them, the so called slow earthquakes and then there is the so-called light of the Earthquake or LIGHTQUAK3, then there are the Subduccion that simply releases the energy, al overlapping a plate under another until it can't hold and like a rubber spring Salta, because in volcanic activity, volcanology and seismology complement each other very well, because low-frequency movements are the form of warning that has a volcanic to warning that an eruption is coming, precursor signs or those movements for a few years have served as a warning to anticipate an eruption.
I leave you a picture as it is a volcano (MIK3)
PICA PICA is going to make you wiggle a lot, take care of you.

They locate 21 earthquakes in the area of ​​the eruption, two of them felt
The maximum magnitude recorded is 3.6 (mbLg) corresponding to the earthquake felt with maximum intensity in the epicentral zone at 2:13 p.m. yesterday

The National Geographic Institute has located in the last 24 hours a total of 21 earthquakes in the surroundings of the eruption of the Cumbre Vieja volcano, two of them felt by the population.

The maximum magnitude recorded is 3.6 (mbLg) corresponding to the earthquake felt with maximum intensity in the epicentral area at 2:13 p.m. yesterday, according to information provided by the IGN.

Two earthquakes have also been located at depths of around 30 kilometers and a shallow earthquake in the area near the eruptive mouth .

According to the IGN data, the volcanic tremor signal maintains its stable level at levels similar to those of the previous days in a range of average values ​​with respect to those observed since the beginning of the eruption.

The height of the column of ash and gases emitted by the eruption, measured at 7:30 am today, is 4,500 meters, a value slightly lower than the previous day.

In addition, the network of permanent GNSS stations on the island show a return to stability in deformations.

The IGN monitors volcanic activity and has strengthened the surveillance network on La Palma, where it has established an Eruption Attention and Surveillance Center and works daily to collect samples of volcanic material for analysis
