Cumbre Vieja Eruption: Latest Updates


Radio/TV Canarias.


Also, as of November 26:



November 26, 2021, 12:07 p.m., Pacific: It just goes on and on. Here’s some nightmare fuel: a new vent opening up right under a house (which was evacuated long ago). A drone happened to catch this distant view:

October 31, 2021, 11:04 a.m., Pacific: There haven’t been many updates because the volcano just goes on and on and on.

Apparently they have decided to allow some volcano tourism in, as El Mundo today reports that PEVOLCA “appreciates” the hundreds of people there to experience the eruption for themselves and goes on to explain the rules (Spanish).

As for the volcano, per El Mundo via Google Translate and me, a little:

The ash covers the entire west and northwest of La Palma.

The director of the National Geographic Institute (IGN) in the Canary Islands and spokesperson for the Pevolca Scientific Committee, María José Blanco, who has also participated in the same press conference, has highlighted that in the last 48 hours there has been a considerable immission of volume of ash that has covered the entire west and northwest sector of the island of La Palma.

This phenomenon has been accompanied by audible explosions of great intensity and could be caused by an intense degassing process. There have also been several volcanic [lightning flashes] – the Aemet registered 16 lightning strokes between 09:48 and 22:23 yesterday – and shock waves associated with the most energetic explosions of the volcano.

Decreases seismicity but not lava production

Miguel Ángel Morcuende, technical director of Pevolca, announced this Sunday at a press conference that there is a decrease in the number of earthquakes and their magnitude, but it is not accompanied by a decrease in the production of lava. In fact, the lava, which is very fluid, continues to feed into the main streams.

Most of the seismicity is occurring, as he has commented, “in intermediate zones” and the deformations remain stable. The sulfur dioxide emission rate in the plume continues to decline.

“We have been going down for five days,” Morcuende pointed out, but he insisted that, despite this, it continues to remain “very high.”

In addition, he has announced that in the last 20 hours there has been an increase in suspended particles, mainly in Los Llanos de Aridane.

Morcuende has also reported this Sunday that the production of lava has increased in the La Palma volcano, and has recommended to the citizens of five municipalities not to go out on the streets. In the Aridane Valley, which are Los Llanos, El Paso and Tazacorte, as well as in Puntagorde and Tijarafe.


October 25, 2021, 9:58 p.m., Pacific: From El Mundo, per browser translator:

4.00 THE VOLCANO OF LA PALMA IS SURPASSED EVERY DAY: MORE LAVA, ENERGY AND SEISMICITY

The volcano of La Palma is at its maximum activity since it erupted and continues to be overcome day by day, with constant overflows of lava, new emitting points, an increasing seismicity and the greatest amplitudes of the tremor signal in a month.

It could be said that “we are at the starting point or at the moment of more activity,” says David Calvo, spokesman for the Volcanological Institute of the Canary Islands (Involcan), and that five weeks have already passed since the eruption began in Cumbre Vieja.

Calvo judges “a nonsense” the emission of 53,600 tons of sulfur dioxide measured yesterday, which accounts for the intense activity of the volcano, which has five eruptive mouths open and various outlets through which more liquid lava comes out, and ten flows are counted.

In the last 72 hours events have accelerated, with overflows and partial breaks of the main and secondary cones, the opening of fissures and the fall of “great avenues” of lava that for the moment are running mostly through the original flow, which reached the sea forming a belt, which has increased in size.

Well, at least that’s good news about the sulfur dioxide. I was wondering if it had sickened anyone. Hopefully, the true level is much lower.


October 25, 2021, 12:20 p.m., Pacific: This was tweeted a little over half an hour ago. It’s going to be a long night for everyone on western La Palma!

October 25, 2021, 9:23 a.m., Pacific: The volcano emitted almost 54,000 tonnes of SO2 yesterday. Am only a layperson, but that suggests to me a huge amount of recharging magma. As it erupts, it appears to be shouldering weaker parts of the cone aside.

This was tweeted about an hour ago:

There are at least six active openings in the cone now.

Per El Mundo via browser translator and me (a little):

The signs are clear: more vibrations inside, more mouths in action — there are already six — another collapse in the cone and the expulsion in the last hours of “great avenues of lava”.

The spokesmen of the Volcanic Emergency Plan have also acknowledged that “a lot of seismicity” is being detected between 10 and 15 kilometers underground. And while they haven’t talked about additional prevention measures for residents on the island,they have pointed out that, if the associated earthquakes gain in intensity, citizens would have to protect themselves from the possible fall of objects from buildings and facades.

18.24 A NEW COLLAPSE IN THE CONE OF THE VOLCANO OF LA PALMA

The Volcanological Institute of the Canary Islands has reported through its Twitter account that around 17:00, island time, there has been another small collapse of the cone of the volcano of La Palma. It has been detected hours after María José Blanco, director of the National Geographic Institute in the Canary Islands, explained at noon that “the greatest risk” in this scenario of so much activity is a break in the upper part of the main cone.

16.41 A NEW MOUTH, THE SIXTH, BEGINS TO EMIT LAVA ON THE FLANK OF THE VOLCANO OF LA PALMA

The Volcanological Institute of La Palma has recorded shortly before three p.m. in the afternoon, island time, that it has opened a new mouth on the flank of the volcano of La Palma. In a later video, this organization collects how the multiple emission centers are appreciated. And at three o’o’s in the afternoon, four o’t in the Peninsula, his recording shows “an impressive lava overflow”.

14.40 THE EMERGENCY PLAN RECALLS SELF-PROTECTION IN THE FACE OF INCREASED SEISMICITY

At monday’s press conference, the spokesmen of the Emergency Plan were asked if any major earthquake was expected in the coming hours and if that would imply any additional measures. “With the magnitudes that are being given and those that are possible to be reached in the coming hours, the maximum intensity is [Mercalli Scale] VI,” responded the director of the National Geographic Institute in the Canary Islands, María José Blanco.

In that scenario, as he said, the self-protection measures that citizens should adopt would be to “minimize damage by falling objects from nearby buildings or by being near building facades or near street lamps.”

14.25 THE VOLCANO OF LA PALMA REGISTERS “A LOT OF SEISMICITY” AT BETWEEN 10 AND 15 KILOMETERS DEEP.

The director of the National Geographic Institute, María José Blanco, has provided this afternoon data that corroborate the vigor of the volcano five weeks after the eruption began in La Palma: the rate of emission of sulfur dioxide measured on Sunday was 53,600 tons and a greater seismicity was detected at intermediate depths.

In fact, on Sunday there was “a lot of seismicity” in the area between 10 and 15 kilometers deep with a very important peak around 4:30 p.m., when the seismicity rose markedly and there was an earthquake of magnitude 4.0 felt with an intensity IV and with epicenter at 10 km deep.

14.22. THE EMERGENCY PLAN CONFIRMS THE EMISSION OF “LARGE AVENUES” OF LAVA FROM THE VOLCANO OF LA PALMA

The technical director of the Volcanic Emergency Plan of the Canary Islands (Pevolca), Miguel Ángel Morcuende, recalled this Monday before the media that since the beginning of the eruption of the volcano of La Palma, on September 19, ten magma emitting centers have been counted, some of which have been opening and closing throughout the eruptive process, and now there may be five fully active.

“Great avenues” of lava from the open fractures under the main cone of the volcano of La Palma run this day mainly through the original wash, which reached the sea forming a lava delta, which has grown in the last hours.

That greater flow of lava through the laundry that devastated the neighborhood of Todoque has filled the islands of vegetation known as ‘kipuka’, and razed the houses that had been left unscathed, especially in the area of Alcalá.

That extraordinary contribution of lava is also reaching the other two flows that approached the sea, but not enough to advance on their leading edgr, as Miguel Ángel Morcuende has specified in the appearance of this noon.

The rest of the flows, he said, are “quite slowed down”, including the one coming from the eruptive mouth further south, which has been stopped in the area of Corazoncillo, in Las Manchas, next to a photovoltaic plant, and the one that reached the urban area of the neighborhood of La Laguna.

Good thing someone rescued (Spanish) the trapped dogs in Todoque before this!

Meanwhile, from a scientific viewpoint:

Partial translation per Google Translate:

In this viewer of the @IGNSpain a perfect alignment of eruptive mouths of the eruption in #CumbreVieja on the island of #LaPalma is observed.

Like everything in nature, the alignments are not accidental…

And yes, that is a devastating eruption flow rolling over most of the densely inhabited western part of La Palma, with Round Two apparently on the way.
