Update from Mike Hayward on Volcanes y ciencia hoy

Mike Hayward

Hello good morning to tod@s sorry for the dire nights you are going through. The magma hits is what we call the serious pica pica it would be very good that in comments you say, type of moves that are if from top to side sensations you have down below as if something hit the ground. This clear can not deny the magma ascends there is a great contribution in depth of Magma, we go the upper magma camera is reallocated from a lower than in turn that magma command more inferior, from the mantle itself so that viscosity and fluidity when comes to the surface and moves so fast and being at more 1700° is what happens Hawaiian-looking eruption, remember that all movements fill out the macro seismic form, and if it's very superficial, leave it in constant 112 , and if possible downloads ′′ THE VOLCANO DISCOVERY APP ′′ To follow the seismic activity as they are apps that if you put your area warns you before there are earthquakes for 3 steis safe send you and we send you the largest of the affections and hugs (ENRICH AND MIK3)

Here's something similar to what's going on was from the 2017 crisis in the Palm.

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.

The 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

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.

The tremors shake Fuencaliente de La Palma
The southern municipality of La Palma sees its seismic activity increase in coincidence with the resurgence of the volcano

During the last night, the municipality of Fuencaliente de La Palma registered a succession of earthquakes in coincidence with the changes experienced by the Cumbre Vieja volcano and the increase in its eruptive activity, after the collapse of a part of one of its cones.

According to data from the National Geographic Institute, between 10:30 p.m. on Sunday and 8:00 a.m., this Monday morning, Fuencaliente de La Palma was shaken by twelve seismic movements, four of them with an intensity greater than 3, and only one , which occurred around 11:45 p.m., with a strength of 2.9.

The most intense was the one that occurred at 00.17 hours on Monday, with an intensity of 3.7 , which resulted in the highest record of the same, only equaled by the one experienced by Villa de Mazo.

The Pevolca technicians have clarified that these are "normal" movements in the eruptive process and call to calm the population of La Palma, which has felt several of the seismic movements of the last hours.
