Informative update: From 15:00 p.m. (Canary Time) today, October 2, 2021, the Canary Seismic Network on the island of La Palma records a rebound in the extent of the volcanic tremor related to a increase in Strombolian type explosive activity.

When an eruption is going to take place , it is announced, generally by a more intense release of vapors and by seismic shocks , more or less intense earthquakes . It begins with the projection of the solidified lava culotte, broken into a multitude of fragments. But it also happens, sometimes, that the crater changes and that the eruption occurs at another point on the surface. A column of smoke, made up of dust and lava, water vapor and various gases, rises from the volcano , sometimes reaching heights of up to 11,000 meters . During the night, the volcano is illuminated by the reflections of the incandescent lava.

Most volcanoes issue various types of warnings before the eruption begins. Although a volcanic eruption can occur without any prior signal, it is most likely that certain Events will warn us of the next eruption. The magmatic eruptions , for example, involve the output of the magma to the surface and this upward movement normally generates earthquakes detectable, can deform the surface of the earth and cause changes in temperature and chemical composition of the soil and spring water. The people who live

near volcanoes you can detect some of these Events before an eruption. Both the frequency and intensity of earthquakes tend to increase before they start. They can also be preceded by fumarolic activity and by new or larger areas of warm soil .

However, most of the precursor changes are too subtle to notice, and it is essential to use the most effective means of monitoring the volcano , including a wide range of geophysical, geodetic and geochemical techniques. Seismographs are used to detect and locate tremors related to the rise of magma. Other techniques include measuring changes in heat flow in the volcano . Changes in the composition or relative abundance of fumarolic gases can also precede volcanic eruptions and can be detected through frequent gas analysis.


These techniques can be helpful in spotting warning signs of an impending rash. However, the overall success of a surveillance system depends on detecting and interpreting precursor signs early enough to warn and evacuate people from threatened areas and initiate other measures to mitigate the effects of the eruption. Although these monitoring systems can be useful to indicate an increase in the probability of volcanic activity and its location, they do not indicate the type or scale of an impending eruption, nor the Volcanic Explosivity Index that it will reach. Before the Tambora eruption In 1815, for at least 6 months and perhaps up to three years before, some of these signs had occurred, such as increased fumarolic activity and small phreatic eruptions, but no one could imagine what would happen: the eruption reached an IEV of 7, causing, among other things, the year without a summer in 1816 . The precursor signs can persist for weeks, months or even years before the volcanic eruption begins or they can subside at any time and there is no eruption. Thus, monitoring volcanic precursors can give us a general warning of the increased likelihood of volcanic activity in a given area, but it will not tell us when the eruption will be or if, in fact, such a volcanic eruption is going to occur.

Let's see what are these manifestations that precede a volcanic eruption and that allow us to take action if we know what to do in the event of a volcanic eruption :

The rise of magma causes earthquakes . The slow ascent produces a progressive increase in the intensity and frequency of these tremors. This process can begin months before the eruption.
The rise of the magma also causes subterranean noise in the area in which the volcano is located. These noises can be dull or dry, like something breaking.
If there is frost or ice, it breaks, until it melts due to the effect of heat.
There is an increase in temperature in the waters near the volcano and in the soil, which can cause the death of the vegetal mantle.
The animals can behave abnormally, to perceiving vibrations that we can not grasp.
It is possible to see fumaroles , and if these already existed, there is an increase in the emission flux and even changes in color can be perceived.
Deformations occur in the volcanic building. Your pulsations can be measured and determined using a tilt meter .
When the eruption is imminent, there are small explosions and ash emissions, which increase in intensity and frequency as the moment in which the volcano finally erupts approaches.

Update from Mike Hayward Volcanes y ciencia hoy

''Good morning to todo@s hope you were able to rest as much as possible. We are still in the same dilemma yesterday, since 01;00 we appreciate many explosions generated by the volcanic by that mix of water and magma, and we have a great move, which could be those explosions or hybrid VT movements, and that magma Follow the picnic to pop the Sill. What is the chair? Because of ancient eruptions are created under the volcano a series of layers that with the years between an eruption and another solidifies, and is compact or part of the lithospheric layer below contains minerals or rocks that form that layer and it is complicated to promote ascend.
Then we go to the unidentified movements, there's a big swarm if it can be micro seismicity and what? They're important there are like 300 untraced and if I count them more than 4000 low frequency moves if we count this previous week, the volcano re-ups energy and the tremor increases with a spamodic tremor. There are no catastrophes there are bad decisions (MIK3)''

Lo sé Enrique y yo estábamos siguiendo el proceso hicieron un naranja en cubierto,lo se de sobra incluso el sismo de disparo fue a las 11:02 les hubiera dado tiempo suficiente ...pero((De amarillo a rojo) y no llevábamos días viendo la erupción venir semanas...y ni siquiera tenían planes de emergencias,2 días antes,el día antes y en amarillo había rally.No habia puntos de encuentro el plan de emergencias se hizo un o dos días antes por que no había...eso lo que Enrique y yo desde hace años hemos luchado,por que haya transparencia educación sísmico volcánica,simulacros buenos planes :Ante contingencia volcánica donde entra :GASES CENIZAS,hemos escrito mucho sobre esto hemos hablado sobre esto,no se si habrás leído alguno de los post que hicimos Enrique y yo hace 3 años ,es una pena espero que hayan dimisiones tenéis que lucharlo la vulcanología y la sismología es una ciencia inexacta pero hay las llamadas señales precursoras,Sismo de disparo por ejemplo o que la actividad sísmica empieza a ser somera,marcando VT (Volcano Tectónicos) híbridos y los más importantes los de baja frecuencia. Un saludo (MIK3)


Mike Hayward
I know Enrique and I were following the process they made an orange in cover, I know plenty even the shooting Earthquake was at 11:02 would have given them enough time... but (((yellow to red) and we hadn't been days watching the eruption come weeks... and they didn't even have emergency plans, 2 days before, the day before and in yellow there was rally. There were no meeting points, the emergency plan was made a day or two before because there was no... that what Enrique and I have struggled for years, for transparency education volcanic seismic, drills good plans: Ante volcanic contingency Where it enters: ASH GASES, we have written a lot about this we have talked about this, I do not know if you have read any of the post we made Enrique and I 3 years ago, it is a shame I hope there are resignations you have to fight the volcanology and the seismology is an inaccurate science but there are so-called precursor signs, shooting Earthquake for example or that seismic activity starts to be somera, marking hybrid VT (Volcano Tectonic) and the most important low-frequency ones.

Mike Hayward
Nature has the last word at the moment there is a seismic crisis there, the magma is rising but does not climb from there because there is a layer, called a chair is a layer that is solidified magma of ancient eruptions or may that lithospheric layer, this composed of very very hard material and it struggles to start that area that has it there without going out, and that was what happened in the first eruption, I try there and be so hard that layer wanted and found an easier way out So I could go out there or the main cone. But if it's coming out... will the question have strength to finish that job that didn't finish on September 11th? We'll see you in the next few days with seismicity if you change depth being more hombre (MIK3)

03/10/2021 h Canary Islands.- LA PALMA  ISLAND ERUPTION.- CONTINUES THE SISM-VOLCANIC WARNING UNDER OLD CUMBER WITH HUNDREDS OF FEARS, ONLY GREATER MAGNITUDE ARE LOCATED BY THE NOISE DEL TREMOR.- Seismicity continues and hundreds of tremors are appreciated in the Earthquake under old summit several of them 3 or more. Highlights a magnitude 3.5 Earthquake tonight. In conclusion, the magma is finally progressing and seismicity continues to increase the release of released energy, as seen in the weekly graphic of the accumulated released seismic energy.

You can tell how it happened in the underwater eruption in El Hierro that goes to pulses, which are seen in the sky when it emits the gases and ash, but not only in the volcano, the seismicity goes to blows and looks very well in the function of singer, with fillings of steps in the times that is quiet and climbing steps when seismic swarm seismicity come in. This looks pretty good on the graphics of the last 24 h of the released seismic energy accumulated.
On the chart since the eruption of the last 30 days of the collected released seismic energy, you can see that this second swarm has already released between dicks and flutes almost the same amount of energy as the first swarm that ended with the volcano opening, giving us insight on the energy available and doesn't look like it's going to stop, rather otherwise.
But in the seismograms and spectrums two more things are observed, the noise of the tremor this midnight has fluctuated and has been with more intense periods, due to the strombolian explosions and some hydromagmatics that have occurred at the various eruptive points of the volcano.
′′ As for what happens at the volcano's emission points, Isaac described it wonders:
′′ Strombolian pulses follow and volcanic cone transformation is accentuated. Here we see as the fruit of those pulses, the most effusive mouth suffers a fork in its lava output channel. A relatively powerful explosion is even appreciated, followed by a slight rest. The eruption continues and the volcano is slowly changing its shape."

And delta, the cliff lava continues to fall down by 3 sites, so that, now 28 acres of new land, it goes at a rate of 7 acres a day with a thickness on the front of the flow about 30 m about 500 m away from the cliff and a width of about 600 m in total.

Now we only have to wait for the magma pulses or arreons that are rising through the dikes (vertical fractures or almost full of lava or magma) and leaving and the seismicity that comes along this line and although they announce to come up by the increase in seismicity in the deep area of the island 10-12 km, not many. We'll see.

These vertical dikes normally have their origin in a sheet or layer of magma that forms under the island as a horizontal dam or ′′ chair ′′ that lifts the island as if a hydraulic cat was treated, which has already passed in El Iron (stayed more than 40 cm lifted after the eruption) and makes the starting point of those vertical dams by which it starts to upload material after fracturing the rock of the roof of that flat reservoir or chair, on the way to the surface and where It usually stays forever good part of the material, causing the island to rise.

The fajana of the volcano continues to grow fed by four flows
The fajana continues to grow with four sources of food, said the expert.


The fissural eruption of the Cumbre Vieja volcano, on La Palma, continues to present explosive and effusive phases, as explained by Carmen López, director of the National Geophysical Observatory during the press conference offered by Pevolca

In the last hours the emission of gases has decreased, although the orientation of the wind has forced to paralyze the entrance of the residents to the exclusion zone, scheduled for this morning.

Explosiveness increases and a new mouth is not ruled out

The morphology of the main cone changes continuously and, currently, it is wider and lower and is more closed, said López.


On the other hand, the column of gases and ash emitted by the volcano reaches 3 kilometers, and in a more dispersed way reaches heights of up to 5 kilometers.

The explosive activity during the last hours has resulted in the emission of large volcanic bombs that have fallen at the base of the cone.

In the next few hours, the area most affected by the ash will be the southern part of the cone and the ash cloud could reach El Hierro.

Land continues to be recorded between 10 and 15 kilometers south of the cone, the largest of which is 3.6 on the Richter scale

The Pevolca Steering Committee has ordered this Sunday the evacuation of the scientists and the personnel of the different emergency services that were developing their work in the areas near the La Palma volcano outlet, taking into account air quality measurements .

The technical director of the Steering Committee, Miguel Ángel Morcuende, explained at a press conference that the air quality this morning "was not the best" in the area where the evacuations took place, which are the vicinity of the laundry and the interior from the previously evacuated area.


Miguel Ángel Morcuende has clarified that this problem "strictly" affects these areas and assured that in the population centers that are outside the security perimeter, set at 2.5 kilometers from the main cone, there are currently no quality problems from air.

In any case, it has been reported that suspended particles continue to affect, a phenomenon associated with the volcano, to which are added suspended dust from the African continent and that last Friday forced the confinement of several neighborhoods.

On the other hand, Morcuende explained that, according to the latest data provided by the Copernicus satellite -of last night at 02.00 hours-, the affected area is already 399 ha, about 52.5 ha more than yesterday. The maximum width of the wash is 950 meters and there are 30.7 km of roads that have been left unused. Likewise, 1,074 buildings were affected by the eruption, 946 of them destroyed and 128 damaged. As for the people housed, there are 205 housed in the Fuencaliente hotel.

Regarding the problems of drinking water supply and irrigation in those neighborhoods of the municipalities of El Paso and Los Llanos that are located south of the intersection of the coladas, the technical director of Pevolca indicated that they are trying to solve and reported that there have been no incidents so far in the electricity supply or in telecommunications.

Regarding the runoffs that have emerged in recent days, Morcuende pointed out that they continue to be monitored and watched, adding that the area of ​​the fajana is currently 28 ha.

The seasons that receive data horizontal, come on the balloon continues to inflate, 30 cm deformation in the two seasons not, but there is something that does not square this stable and increases, there is more pressure below than in a bottle of coke just fallen to the ground... this volcano takes strength.. we'll see in the next few hours or days, but it could follow seismic activity over 3 even 4 watches.
Where are those untraced movements of today in Catalog B, most low frequency movements.. and that marks repeating the pattern of the beginning of this crisis...

Caution: a cloud of sulfur dioxide reaches Puerto Rico from the volcano on the Spanish island La Palma
It is expected to affect the air quality on the island more strongly until tomorrow, Monday. The Department of Natural and Environmental Resources urged the population to limit their activities abroad.


The extensive cloud of dust from the Sahara that will affect Puerto Rico at least until Tuesday appears to be more intense than usual, after satellite images showed that it contains sulfur dioxide (SO2) particles that come from the Cumbre Vieja volcano, which exploded. in mid-September on the Spanish island La Palma, part of the Canary Islands .

One of the cones gives way and several mouths of the volcano are joined
A higher lava flow is observed and the eruptive cloud of La Palma reaches up to 4.5 kilometers

One of the cones of the volcano that has been emitting lava in recent weeks has given way and collapsed, so that several of the active mouths of La Palma's eruptive process have joined .

This has been confirmed by the operation that makes up the advanced command post Drago 01, on La Palma. The same sources, explain from the Government of the Canary Islands, have been able to verify this Sunday night a greater flow of lava outflow that is flowing through the same channel that had until now .

No new affectations have been observed.

On the other hand, from the Civil Guard it is reported that the affected area reaches 399 hectares, which is 52.5 more than on Saturday .

The Pegaso Civil Guard team drone has recorded the column of smoke, gas and ash, which already rises to 4.5 kilometers.

 04/10/2021-8:00 h Canary Islands.- PALM ISLAND ERUPTION.- THE WARM OPENS AND ERUPTION TOO.- The seismicity tonight has been more intense and continues to squeeze mode with more than a dozen tremors of 3 or more in the area under Old Summit after 3.7 yesterday, so seismicity will follow for the next few hours where I do not rule out any earthquake in the environment of the 4.

In the graphic released seismic energy accumulated or ladder of the devil, the system continues to increase its emission rate, i.e. non-loosen and more moderate seismicity is foreseeable, as I say I expect some movement in the environment of M4 or more magnitude ( Enrique)

The seismic swarm in the south of La Palma reactivates with more than 40 earthquakes
The most prominent among those located by the IGN National Geographic Institute are one in the southwest of Mazo, of magnitude 3.4


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.

he magma of the La Palma volcano contains tephrite and has been evolving under the island for thousands of years
As explained by the geologist José Mangas, the latest eruptions on La Palma have also been tephritic, in which not a "father or mother" magma has been expelled, but a "son" magma, colder and rich in silica, sodium and potassium


The data obtained by scientists from the magma of the La Palma volcano, whose eruption began two weeks ago, indicate that it contains large amounts of tephrite (a gray and whitish volcanic rock rich in alkaline feldspar. It is incandescent and comes from the mass in melting inside the Earth), indicating that it has been evolving under the island for thousands of years.

The geologist and professor at the University of Las Palmas de Gran Canaria (ULPGC), José Mangas, explained on Televisión Canaria that two days ago the composition of the magma that is rising to the surface was known: a tephritic magma.

José Mangas has pointed out that this means that a primary magma is not coming out of the mantle, that is, it is not the partial fusion of the mantle that is under La Palma that is coming to the surface.

The geologist has pointed out that this magma has been under the island for thousands of years evolving in a chamber in the upper part of the upper mantle and a bit of oceanic crust, so it would be a "son magma" and not a "father magma. or mother ", which has basaltic compositions.

Mangas pointed out that the latest historical eruptions on La Palma have also been tephritic (San Juan, Teneguía, El Charco, etc.). Then, in the last 300 years, the magmas that have come out of La Palma are colder and richer in silicon, sodium and potassium.

Regarding the possibility of new islands being generated as a result of this eruption, José Mangas has totally ruled it out. "That doesn't make any sense," said the geologist, who assured that there will be new islands because La Palma, like the other islands of the Archipelago, are volcanic buildings that have needed millions of eruptions like the current one to form.

The volcano emitted 16,000 tons of sulfur dioxide this Sunday
SO2 emission is closely related to magma emission rate


According to the Volcanological Institute of the Canary Islands, the emission of sulfur dioxide (SO2) into the atmosphere from the current eruptive process in Cumbre Vieja was 16,000 tons this Sunday.

This quantity can be considered underestimated as a consequence of the limitations presented by the measurements made with remote optical sensors type miniDOAS in a land mobile position, with the instrumentation mounted on a moving vehicle .

The interest in monitoring this geochemical parameter is that the SO2 emission is closely related to the magma emission rate in this type of volcanic system. If a downward trend is observed in the following graph for this parameter throughout the eruptive process, it will be an unmistakable sign that the eruption is nearing its end.

Lava already affects 400 hectares and the fajana already occupies almost 30
The air qualities in the non-evacuated areas close to the volcano's emission are within normal levels


The lava from the Cumbre Vieja volcano, on La Palma, already affects about 400 hectares and the marine delta (or fajana) that has formed in its fall into the sea occupies an area of ​​almost 29.7 hectares, according to the information updated this Monday by the Department of Homeland Security (DSN).

The partial collapse of the cone structure last night seems to have joined the eruptive mouths of the volcano, which is causing a greater flow of lava, which reaches at certain points almost a kilometer in maximum width.

The ash mainly affects the southern slope of La Palma and it is not ruled out that finer ash particles may reach the island of El Hierro, according to the DSN.

Given the decline in air quality in areas close to the laundry, it was decided to evict the scientific and emergency personnel, as well as the neighbors who went to collect belongings from their homes.

According to this source, the quality of the air in the non-evacuated areas near the volcano's emission are within normal levels.

On Sunday 16,000 tons of sulfur dioxide (SO2) were emitted , according to the Volcanological Institute of the Canary Islands (Involcan), an amount that could be even higher due to the limitations of measurements made with remote optical sensors type miniDOAS in a land mobile position (with the instrumentation mounted on a moving vehicle), explains Involcan on social media.

The interest in monitoring sulfur dioxide responds to the fact that the emission of this geochemical parameter is "closely" related to the rate of magma emission from these types of volcanic systems, adds Involcan.

If a downward trend of this geochemical parameter is observed during the eruptive process, it will be an "unequivocal" sign that the eruption is nearing its end, he explains.

Problems with the supply of drinking and irrigation water

As for the provision of basic services, and l electricity and telecommunications supply operates normally, but not the drinking water supply and irrigation , which has been affected in some towns of El Paso and Los Llanos.

To guarantee the irrigation of the affected plantations, it is expected that today two portable desalination plants will arrive in La Palma to be installed in the Puerto Naos area and a tanker with a capacity of 30,000 cubic meters has been transferred from the peninsula that will allow to increase the water flow for irrigation.

The National Geographic Institute (IGN) has located an Earthquake of magnitude 3.7 in Fuencaliente early Monday, about 11 kilometers deep, after a night of high seismic activity.

Another of magnitude 3.4, also early in the morning, located in Mazo at a depth of 13 kilometers, has been felt by the population.

Between the other 3.7 Earthquake, located at a depth of 12 kilometers in the southwest of Villa de Mazo , around 8.15 p.m. on Sunday, and the latter, registered at 7.20 a.m. today, the IGN has counted up to 40 tremors, all of them distributed between Mazo and Fuencaliente.

The Supreme Court confirms the nullity of Ryanair's ERTE in the Canary Islands
It affected about 200 workers from the bases of the archipelago and Girona

EFE
Madrid
Monday, 4 October 2021, 12:27
The Supreme Court has confirmed the nullity of the temporary employment regulation file (ERTE) applied by Ryanair to some 200 workers, mostly from the bases of the Canary Islands and Girona , thus confirming the October 2020 ruling of the National Court.

In a ruling dated September 22, the social court endorses the criteria of the Ministry of Labor, which considered unjustified the concurrence of force majeure requested by the airline with respect to workers who had been fired before the pandemic and whose dismissal it had been declared void.

The processing of the file was carried out without informing the unions on the list of those affected, and there was also fraud of the law, since Ryanair tried to ensure that a large part of the processing salaries that it had to pay were paid by Social Security through unemployment benefits.

In May 2020, Ryanair submitted a request to include 206 workers in the ERTE due to force majeure - due to the Coronavirus pandemic - of which 12 of them were not included in the ERE and not in the previously requested ERTE .

Subsequently, the Ministry of Labor annulled said ERTE based on the Inspection report, which considered it to be a "fraud of the law" since what the airline was looking for was "to get rid, if not of all, yes of a good part" of the payment of the salaries and social contributions of the 224 workers of these centers that the National Court forced to readmit last April.
