Scientists have warned that if the advance to greater depths in the sea of ​​the lava delta or fajana continues generated by the volcanic eruption on La Palma , a collapse of its front could occur that would be accompanied by the sudden release of gases, with hydromagmatic explosions and waves.

The spokeswoman for the scientific committee of the Canary Islands Volcanic Emergency Plan (Pevolca), María José Blanco , pointed out at a press conference this Friday that this situation could occur because the fajana has reached the limit of the island platform and therefore its advance is foreseeable.

Blanco added that the Weather conditions are unfavorable for air quality, which for the moment remains at a "regular" level, although the forecast is that it will improve as of tomorrow with the turn of the wind to the north component between 1,500 and 5,000 meters and a rise in thermal inversion, now stagnant at 700 meters.

Until these meteorological changes take place as of Saturday, the ash and sulfur dioxide plume that extends from the volcano is affecting the operation of the La Palma and Tenerife North airports, and may arrive this afternoon at the Tenerife aerodrome South and, at night, to La Gomera.

Apart from the atmospheric complications, all the parameters that are monitored for the follow-up of the volcanic eruption, which began on September 19, indicate that for a few days it has been in a stable phase or "valley", in the words of the technical director of the Pevolca, Miguel Ángel Morcuende.

Thus, the daily emissions of sulfur dioxide from the volcano reach 4,994 tons and the diffuse emission of carbon dioxide 1,668 tons per day, values ​​similar to previous days, and there are no significant patterns in the deformations.

Only seismicity has continued to increase in number and intensity, always at a great depth of more than 10 kilometers, which makes the possibility of a new eruptive center far from the main cone "extremely rare" for the time being.

The lava covers an area of ​​471.8 hectares, 40.6 hectares more than on Thursday , after a bifurcation near the coast, southwest of the main stream, an appendix that is about 150 meters from the sea and at the moment it is projected on El Charcón, formed in the San Juan eruption in 1949.

The main stream "is filling gaps and looking for heads of small basins" so it is not ruled out that the magma ends up covering the surface that separates it from the appendix.

Regarding the affections to crops, the latest measurements indicate that there are 120 affected hectares, of which 59.39 are banana trees, 33.43 vineyards and 7.36 avocados.

The destroyed buildings have not been updated this Friday and are around 726 according to measurements of the cadastre in previous days, while the roads covered by lava total 26.47 kilometers.

As the air quality is regular, the people of the Aridane Valley, where there have been some specific measurements that have exceeded the alert levels of sulfur dioxide that have later remitted, can lead a normal life but with a mask, except those who suffer lung or bronchial conditions, asthma, heart problems, pregnant women and young children, for whom it is recommended to go outside as little as possible and always wear a FFP2 mask.

Those responsible for the Pevolca have insisted that cleaning the ashes should never be done with blowers, that what they do is fan the ashes and put them back into circulation.

08/10/2021 h Canary Islands.- LA PALMA ISLAND ERUPTION.- THERE IS SISMIC PATRON EVERY 12 h 25 min BETWEEN THE MOST INTENSE TERREMOTES, THE ENJOY KEEPS UP ITS RATE EMISSION OF ENERGY AND PRESURIZE. WHILE THE SOUTH ADVANCE COLLADA.- The contrasting data is what it has, it turns out that when one looks closely these I do nothing but see a seismic swarm that grows more every day, releases more seismic energy and becomes more powerful with earthquakes getting stronger and keeps climbing, it keeps getting bigger and bigger.

The last thing we are showing by the ladder of seismic energies released, is that in addition to a pattern with significant steps separated by about 12 h 25 min, shows us in the last few hours, seismic breaks, which means that the magma is encountering difficulty in advancing, which produces pressurizations and that instead of releasing energy with many earthquakes, do so with few and more intense.....

But I have to stress it's a prediction and sometimes yes, sometimes no. This is like when they say what's going to rain. can fall between 20 and 40 litres per square meter, finally fall 12. It rains, since it's already. Yesterday decided that he wasn't going to move too strong and even though he did, it wasn't very meaningful and went a little ahead.

But the pattern continues to be fulfilled and if you see today's next step is for a little before las13:00h (12:55 h) today. put a pitchfork in a few minutes and look what we had.

Well, there have been significant tremors. It's a pattern and you have to follow it, I have nothing else
And the next maximum, 12 h 25 min later according to this simple pattern (mole like gravitational Tides), will be for IGN's 00:20 h, 01:20 h canary and 02:20 h peninsula. Have a good night and see if it's not too strong. (Enrique)

The next expected hour or maximum probability of occurrence, after the maximum of 12:55 h where several Events have taken place, is for this early morning at 00:20 h IGN, 01:20 h Canary Islands, and 02:20 h peninsula.

Tomorrow another one at 13:45 h IGN, 14:45 h Canary Islands, 15:45 h peninsula. We'll see what happens. Also stress that every 6 h 12.5 min also passes a few minor highs and sometimes also hits some minor remarkable shimmings at 19: 08 h and 06:32 h IGN time.
And according to some reports, it appears that this pattern not only affects earthquakes, but at this time eruptive pulses occur where the volcano ejects more material, doubling or tripling the amount of materials and ashes ejected, sometimes even more.... was what happened last night around 00:30 h-00:40 h.

I really hear the reports and don't understand, I don't know if you're seeing another eruption from another volcano or taking me for an asshole. Neither loosen, nor normal, and I'm not the only one who sees it, on the Volcanodiscovery website, they think alike, the explosions are getting bigger and stronger. The funny thing is that the tremor signal is declining, which doesn't prevent stronger explosions.

https://www.volcanodiscovery.com/la-palm...onger.html

At the moment the eruption is ruled out elsewhere on the island as it is releasing tension and pressure for the current eruptive point and earthquakes are still deep over 5 km and the deformation is stable. However, I still have an eye on Old Summit in the Nambroque area, not to change my mind and do as in 1949. Sleep calm in the Mazo and Fuencaliente, at least the next 24 h-48 h, but more... that doesn't climb so fast.

Finally, the video of the new south arm formed yesterday shows us how it has widened and how it covers more plantations both up and down in the Fajana. This is going to be very long, surely there will be more breakage, and not only for the south but also for the north, surrounding the mountain of Todoque in the north, generating another entrance, my recommendation is that you get all your worth out there .. cheer and luck.

''During the past hours, the eruption has been becoming stronger, with pressure increasing in the main cone, our correspondent Victor from the Canarian volcanological society Volcanes de Canarias reported.
Strong ground vibrations from sustained, near-constant explosions can be felt in nearby areas, such as shown in the video taken at 9.17 a.m. local time from Tacande, at 3 km distance, taken a short time ago:''

In the curve of the last 24 h of the released seismic energy accumulated according to the function of singer or ladder of the devil, it is observed that the system makes much more marked steps (with more horizontal stretches and larger vertical steps), which indicates less seismicity between remarkable Events and that the magma has encountered a hard rock, which does not let it go partially or in its entirety and raises the pressure, pressurizes until it part with new stronger earthquakes.

The volcano strip runs the risk of fracturing and causing a strong swell
The director of the National Geographic Institute (IGN), María José Blanco, warns that it could cause explosions, sudden release of gases and waves
Madrid
Friday 8 October 2021, 17:48

The strip of the La Palma volcano, the terrain formed by the mouth of lava in the sea, is in danger of fracturing. If this collapse occurred, gases would be released abruptly and explosions in the water and large waves would occur. The director of the National Geographic Institute in the Canary Islands, María José Blanco, warned this Friday that such a possibility could occur because the delta "has reached the limit of the island platform" and, consequently, "it is foreseeable that it will continue its advance" . The phenomena that arise as a result of the collapse of the lava delta will not pose dangers to the population, according to experts.

On the twentieth day of the eruption, the lava tongue that was diverted on Thursday continues to destroy banana plantations in its advance. The language moves through the fajana created by the San Juan volcano in 1949, where it was precisely possible to recover ground to build those exploitations that are being devoured.

The front that has become independent from the main wash is located about 150 meters from the sea and leads to the beach of El Charcón. As it progresses, more farms and greenhouses will be devastated. This Friday, the scientific committee was concerned about air quality, which is expected to improve today due to the change in meteorological conditions, which will favor the dispersion of gases. The dense ash continues to thin the air in the north and east of the island, a circumstance that prevents air traffic. This situation also affected Tenerife, where flights had to be diverted from north to south due to the closure of the aerodrome located in the northern part of Tenerife. Another factor of concern is the incessant seismic activity, which put residents of municipalities such as Villa de Mazo or Fuencaliente on guard.

08/10/2021 h Canary Islands.- LA PALMA ISLAND ERUPTION.- MISSING SITES AND MEMORIES OR ALMOST - NATURE IS UNSTOPPABLE, VOLCANO AND DEEP WARM OF COURSE.- It's impressive how an erupting volcano directly makes the entire zone of confidence disappear and much of the memories of the lives of many people who are left uncalled for and in strange places without being able to see their previous life again. My recommendation is that when this is over, you have to redo your life as best as you can. This is so hard. This volcano and deep swarm are going to do what they have to do and right now, I can pretty much know what will happen in a few hours, in a few days... but no more.

What I do know is that it will stop someday, as he has done many times before, but I don't know when... and at least it won't be before two weeks. The deep swarm worries me as it may be something we have not seen causing a new eruption in another part of the island if deformation, gas and seismicity so indicate or simply stay a day without gas or energy and the volcano stop just stop. That would be the best.
When it ends, after a few days or hours break, I do not rule out any extertors at the end of the eruption, reactivating for a short space of time, but ending well-finished.

https://twitter.com/i/status/1446494081891377162

But this is nature, relentless, numb, merciless and merciless and when you get in its way it takes you ahead. If you step aside you can go back and try to make a new life and new memories. I hope they let people recover much of what was lost when this is over, as even though the volcano erupts again, it will give time to enjoy life and learn new experiences.

Our elders rebuilt the Canary Malaysians with a lot of effort speeding up the natural process, placing new fertile land in benches brought with beasts from other parts and on ancient flows and making it productive again by taking wealth from where there was only one erial... ′′ a malpaís ".
The best example worldwide is the region of the Geria in Lanzarote, where after falling several meters of pyroclasts during an eruption that lasted 6 years, they managed to continue to cultivate the vines and did something amazing, unique in the world .. They went ahead and did well, so well that today everyone remembers and admires them as well as tasting one of the best wines on the planet.

This area within 30/50 years - if there are no more upcoming eruptions in the area - will be a paradisiac area to live, as it was before the eruption, I have no doubt about that and if people are allowed to recover part of their past rebuilding it will be the best thing to do. I hope they let you rebuild Todoque and his church, his school, his health center and his shops and their homes in honor of all the islanders who suffered the eruption and that there put in remembrance of all, that the Palmeros Canaries that the volcano could not with them and that they all survived.

When in 2002 I was in Hawaii, on the big island, I was very aware of the ravaged area of the old town of Kanapala.. 300 houses and shops and almost nothing left... but a few neighbors are They were and slowly rebuilt their homes and their lives and eventually became a place more or less habitable. It's not like before, but the people who live there have redone their life. It's lively over lava, a neighborhood on rocks: Kalapana's new gardens are emerging directly onto the old gardens of Kalapana, which were buried under 40 feet (12-20 m) of lava in 1990.

https://www.honolulumagazine.com/the-lav...rs-big.../

And you want to start the reconstruction in the Palm there is. From here all my support for the proposal of José Henry Garritano (Enrique)
′′ Jose Henry lost his home, his mother's and architecture studio, sadly affirms that the saddest time of his life and that he would like to start building his village by the church and then the entire neighborhood ′′ blunt asserts that ′′ we have to, we have to ".

I encourage all the islanders... who need it. Today the volcano will give us a truce, that's early morning will have some strong retortion but otherwise, sleep peacefully. Tomorrow more. (Enrique)
