30/10/2021 11:30h Canary Islands. - ERUPTION OF LA PALMA ISLAND. - THE VOLCANO CONTINUES - 5.1 MAGNITUDE Earthquake - STRAYS IN THE SPINE - LOT OF ASH - AND THE 13 UNSTOPPABLE - I already said yesterday that this volcano is reserved and continues to grow, this morning's Earthquake is an unequivocal sign of it. Initially a 5.1 then it went down to a 5.0. But there's more, much more.

LAVA NECKLACE

The 13A colada has reactivated after a stop yesterday when more liquid material arrived and has descended on the south edge of the coladas field towards the Delta of San Juan, going down the cliff and was arriving a few meters of Charcón is gun the last ones photos.

THE VOLCANO: LOTS OF ASH, LIGHTNINGS AND THUNDER.
Today it is a little untatable after the Earthquake throwing many pyroclasts and ash, with more shredding and speed, which gives the eruptive spine the possibility of generating lightning. The air quality in the plains today is not good, the SO2 has reached almost 200 micrograms per cubic meter a while ago and people are suffering it in meat.

And we have lightning officially located, since the improvement of its detection with new sensors has been implemented, which we have been indicated since Involcan a couple of days ago.

And you can even see it on the AEMET visor in the Canary Islands

What I do not understand is the management of data we have, in case someone has not repaired it, it's bashing everything that is not official, cutting the supply of data and only offer prepared things that can not be almost interpreted R. The images say one thing and that data posted another. How serious the touching will be, that the EMSC has given him a magnitude of 4.1... i.e. IGN data has not been taken into account.

Why? I think knowing what is happening, just like Volcanodiscovery, it has failed its computer system because of the subtle change they have made in it to put sticks on the wheels to whoever wants to use IGN data. This ferocious check of information ladies and gentlemen is taking a dangerous character and could be derived from civil and criminal responsibilities to the current eruption managers in the case of a catastrophe for not doing things right.

This changing the data or blocking access to it has a name known as FRAUD to the scientific community and the entire population.

How's the yard, my god, we go like headless chickens.. and on top, it's the second time, already happened with several earthquakes when El Hierro at the end of 2013. (Enrique)

Although the IGN points out that the Earthquake this morning had a maximum intensity IV-V in the Las Palmas-El Tributo area, in Puntallana, the Malpaís automatic station, between El Paso and Los Llanos de Aridane, recorded a maximum intensity VI.

It's the first Earthquake of 5.0 mbLg or higher in the entire eruptive event, which began with the swamp of September 11.

These earthquakes with so much strength at low depth indicate a new contribution of magma from the mantle to the terrestrial crust, which should result in an increase in the number of earthquakes between 7 and 19 kilometers deep in the next J ornaments. And with that the volcano continues its activity in the mid-term.

The restructuring of the mantle under the island of La Palma gets complicated while these types of shakes so strong continue at low depth without several days of rest.

Some comments from the same page.


A medium ago, I don't think I brought them down to conscience, they know that if it was so it's a crime

Mariled Mariscal Felipe
Maria Morales they pass that crime, they know it didn't get to that because much@s eat from the same plate


Marion Torres
Bravo for telling the truth. Bravo for mentioning that the IGN always lowers the intensity in a way that this is no longer speechless. Thank you for telling the truth


Elena Salido de Lara
It's been a long time warning and nothing is done

La Palma volcano survivors shaken but determined to rebuild
By Dan Johnson
La Palma, Spain

Published32 minutes ago


magine trying to sleep in the glare of an erupting volcano, rattled by its tremors.

Then imagine trying to do that in a cramped caravan, after your home was surrounded by lava or buried beneath it.

This is the upturned reality for around 20 families, bedding down for another night in a back street in Los Llanos. They are just outside the exclusion zone on La Palma, in Spain's Canary Islands.

They are the homeless of the six-week-old eruption, who cannot even dream of going home without being woken by the volcano's tremors and rumble.

Dacil Batista shares her small caravan with her partner and their two children, along with her mother-in-law and sister-in-law. "I'm in despair," she tells me, "because I don't know what's happening to my house."

"We spent the first few nights staring at the volcano, trying to see what it was doing, but now it is kind of normal to have it there."

After all these weeks you'd expect deeper dismay, even anger. But Dacil is thankful for the food, clothes and toys from the local town hall and hopes to take her children home one day.

ust across town, El Roque school has a new class.

The children, cut off from their normal lessons, are now being taught in borrowed space using donated books. Their teacher, Christina Mederos, managed to grab the computers but not much else before Las Manchas school was abandoned to the lava.

The walls of this temporary classroom have pictures of the erupting volcano drawn by children across the Canary Islands and sent here in support.

Ten-year-old Rodrigo explains that he's now living with his grandmother: "I thought it would end quickly but the volcano has destroyed houses."

Classmate Sergio describes the lava and the destruction done to the trees, landscape and his grandfather's house. He says the eruption "is beautiful, but it does a lot of damage".

The children can't even play outside, Christina tells me, because the air and school yard are thick with ash. "It was very emotional to come back [to school], because I really wanted to see the children. I didn't know how they felt about it all," she says.

COVID rules suggest the windows should be open for ventilation, but volcanic ash and the risk of toxic gases mean they stay firmly closed. Masks and goggles are all in place before the children step outside.

Scientists have come to La Palma, to monitor the lava, check for gases and analyse the newest rocks on Earth.

Dr Matt Pankhurst of the Canary Islands Volcano Institute shows me the samples taken by poking a long stick into the lava and dropping it, steaming, into a bucket of cold water - live geology lessons in Earth's oldest processes. His main focus is the crystals held within the hardened lava.

"In principle, we can forecast volcanic eruptions like we do the Weather," he explains. "This is the best chance yet to link together the evidence in the rock with the pre-eruption signals, so we can know what's coming next time in much more detail."

It's the story of Earth's formation retold in a devastating act of renewal. On these islands life has always been built on the ruins of a previous eruption.

Tourism also defines the Canary Islands. La Palma has been marketed as "La isla bonita" - the beautiful island. But unlike that Madonna song, this is no longer a Spanish lullaby.

"It was a disaster," says Basso Lanzone, who has run tours here for years. "It changed everything on this side of the island - now they have nothing. No tourists were arriving because they were afraid of the volcano."

So Basso refocused his tours and brought 100 day-trippers from Tenerife to see the volcano.

It's a rare possibility," says Anastasia, visiting from Ukraine. "It's amazing, feeling nature, what it can do."

Mark Fordyce from Aberdeen was on holiday in Tenerife when he saw volcano trips advertised. "I just thought it would be really interesting to come. I saw that the proceeds from this tour go towards relief for the families affected."

Around the main square of Los Llanos workers constantly sweep and clean as more volcanic ash falls.

Architect Henry Garritano Perez lost both his home and studio to the lava when his village, Todoque, was destroyed. "It wasn't a typical neighbourhood," he says, "it was an extended family."

When the pretty little white church where Henry was married finally collapsed, many lost hope. But not Henry, still smiling through the dust. "Even though my roots are under 15m of lava, they are in Todoque. The community has to be reborn."

When I ask how anyone could build on the scorched earth of such a disfigured landscape Henry remains upbeat. "I saw that on Lanzarote [another of the Canary Islands] there are houses literally built on lava. That can be repeated here."

He's realistic, however, that it will be a year or more before the lava is cool enough to start reconstruction.

Too long for Dacil Batista and the others whose world has shrunk to the size of a caravan - families uprooted and scattered across the island.

Yet even here there is no sense of defeat.

"I could take my kids, my animals and we have a caravan to stay in - we're not on the streets," she says.

There is a determination to adapt, cope and survive. But every day more people are affected by the impact of this eruption.

The lava flow this morning has been incredible and is still ongoing.

Update last night courtesy of Enrique.


30/10/2021 21:30h Canary Islands. - ERUPTION OF LA PALMA ISLAND. - QUICK PREVIEW OF COLLADA 13, TREMURRING AND LOTS OF ASH - VOLCANODISCOVERY ON LINE AGAIN. - The day has been tremendous in the valley, with a rain of ashes so thick and thin that the sky has darkened. People have had to stay inside the house with the lights on so they could see. And while the vibrations and constant tremors continue throughout the day, in addition to today's Earthquake.

THE NECKLACE:

Right now the most worrying thing is in flow 13A has gone fast, traveling a little over 1500m, a half kilometer in 24 hours, with tip speeds of 300m and reaching almost the ocean. This has been due to the lava coming out very liquid and hot, looking as if it was water the lowest area. Once the flow is done, it starts to swell and soak up a few meters, which is what we've seen today, partly climbing in the old coladas.

The Norias area has been liberated for the moment, passing through the north but don't let the guard down, because there are two coladas still moving forward and that if there is luck they will stop until another one comes down.

The bad news is that arms will continue to appear south due to the cone configuration and otherwise it will be a matter of days until new areas south of the current coladas field.

The good news is that at first the Bombilla and the Port Naos are safe, while the lavas do not cross the axis of the lavic canal of the lavas of San Juan of 1949 which will have a resumption effect. Another thing is that the delta grows a lot and spreads through the platform, coming danger (the lava coladas) by the sea, as it has happened sometimes in Hawaii (Kanapala 1990, Kapoho 2018) fortunately the platform is not very big and possible mind don't do it. It all depends on how long the eruption lasts.

THE VOLCANIC CONE.

At the moment the coladas supply is guaranteed by the lava tube that comes out of the crater draining the material very effectively and taking it to the Todoque area at a very high temperature over the ancient coladas.

As for the volcano the tremor has been rising for several days, indicating that it is changing again, it is becoming more explosive, which causes it to shred more ash, produce lightning and more explosions. The decline in deformation indicates a more effective drainage of the magma which has caused a drop in pressure that has facilitated water entry into the volcanic system and thus this increase in explosiveness.
However in the spectrogram it is appreciated that there have been changes, one of them has been this afternoon between 14 and 16h where a bit of a lot of magma noise has been produced at all frequencies and suddenly at 16h it has dropped, since then and l low tremor and therefore this episode of explosiveness, let's see what we reserve for tonight, it wouldn't be weird that it even stops, and then wake up again.
SO2 keeps dropping, today it's 15000 tons daily, very high value, but lower than other days.

Volcanodiscovery has data again, which can be seen perfectly as we have the steps of the devil's staircase or function of singer of seismic energy released by the volcanic Earthquake swarm every 3-4 days, matching in with the most intense earthquakes, the pattern continues that if there are no more intense earthquakes next week, the system could start relaxing, clearly. Currently it continues to grow, and earthquakes continue too and the eruption will last at least 2-3 weeks in view of SO2 data, deformation, seismicity and tremor.

That doesn't take us away from surprises, like stopping suddenly for a few hours, as it already did on September 29 at the 10 days of the start of the eruption. Don't worry, he'll come out again with new close mouths or in the same ones as the system has a lot of inertia. The longer a stop lasts, the worse, so the better it doesn't last long until parameters like SO2, up to values below 200 tons per day that would indicate that magma flow is cut deep and the end of eruption. Until then you have to wait.
