01/10/2021 h Canary Islands.- LA PALMA ISLAND ERUPTION.- A THIRD NEW MOUTH MOUTH IS OPENED NORTH OF CRATER AND NEW Earthquake FROM 3.6 UNDER OLD TO 10 KM.- Yesterday a fissure was opened at the top of the cone in the loin area and went down the old lavic canal, which is now out, is the third and is more to the NW of those two, namely about 400 meters away from the cone... and a lot of very fluid lava comes out.

And a moderate Earthquake of magnitude 3.8 very somero magnitude is difficult to auction just 4 km that they have to relocate. edit: They have already relocated it as 3.6 under Old Summit at 10 km.

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.

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..

Regarding seismicity, continues high and with numerous earthquakes seen on the spectrum, indicating that something down there is looking for exit, so the earthquakes will follow in the next few hours / days until it comes out, hopefully in the close proximity of the current eruption. I don't rule out other areas, like in the Nambroque area at Old Summit, just in the vertical of current earthquakes and just as it did in 1949, but the probability there is less. (Enrique)

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