What is a dirty storm or volcanic lightning?
We tell you what this spectacular meteorological phenomenon consists of.

It is a phenomenon that is also known as volcanic lightning, because gigantic electrical discharges are produced like those of conventional storms , but in the plume - the gas column of a volcano when it erupts.

As José Miguel Viñas, physicist, scientific communicator and consultant to the World Meteorological Organization (WMO) explains, “these discharges are formed by a mechanism in some way analogous to that which takes place in storm clouds, in cumulonimbus clouds. If in these it is the friction between the hailstones in the upper part of these cumulonimbus that separates the electric charge and gives rise to these discharges, in the volcanic cloud the elements that escape from the crater, the pyroclasts and the volcanic ashes, enter into friction, which also causes the separation of electrical charge and the appearance of lightning ”.

In any volcano
Dirty storms, therefore, are a phenomenon that can occur in any erupting volcano . The first recorded observation is from the year 79, when the Roman historian Pliny the Younger described the eruption of Mount Vesuvius. It was also there that the first scientific studies of dirty storms were carried out, carried out by Professor Luigi Palmieri during the eruptions of 1858, 1861, 1868 and 1872, which often included lightning activity.

An investigation published in 2008, in the Volcanology Bulletin, pointed out that between 27% and 35% of the eruptions are accompanied by these flashes. In this sense, spectacular dirty storms have been photographed in various parts of the world, such as the Chaitén volcano in Chile; in Colima, from Mexico; on Mount Augustine, Alaska ; in the Eyjafjallajökull, of Iceland; and on Etna, from Sicily.

Soler (CSIC): "Everything is theories, the only reality is that the eruption continues"
The volcanologist from the Higher Center for Scientific Research says that "we are at a crossroads regarding the behavior of the volcano"
- The appearance of elemental sulfur deposits denotes "a clear change" in the dynamics of the volcano

The volcanologist of the Higher Center for Scientific Research (CSIC) Vicente Soler admits that the scientific community is facing "a crossroads" regarding the behavior of the La Palma volcano, because although it has entered a new phase, that does not mean that the end is closer.

"It is not easy to make a composition of a unique place. There are too many parameters at stake and you have to wait several days. I wish it would come to an end, but it is still a wish. We are all expectant. We do not have a crystal ball," he says in statements to Efe.

The Volcanological Institute of the Canary Islands (Involcan) published this Friday that the appearance of elemental sulfur deposits in the main cone could point to a "clear change" in the dynamics of the eruption, not to its end.

Vicente Soler comments in this regard that it is not the first time that this phenomenon has been observed in the Cumbre Vieja volcano.

In what it does coincide is that in the last hours there has been a change in dynamics, with a predominance of a Vulcan behavior over a Strombolian one, since the incandescent pyroclastic plume has almost disappeared.

He qualifies, so as not to generate "a false alarm", that with Vulcan it refers to a phase of gaseous emission with formation of dark brown volutes, and adds that the value of Cumbre Vieja in the VEI explosivity index is two, perhaps three, on a scale of zero to eight.

He also recalls that the eruption of the San Juan volcano (1949) alternated strombolian and Vulcanian phases "from the very beginning."

Around the million dollar question, how much is left of the eruption that began on September 19, Vicente Soler indicates that "there are a series of phenomena that do not help": the main one, which is now "very difficult" to quantify how much lava it is coming out because the main point of emission pours over a volcanic tube.

"In the first 500 meters the lava is not seen; further down it falls down the promontory that was created by the last collapse of the cone and then there is an upwelling of lava that spreads on several fronts, which later merge", he describes.

"Before with a pair of binoculars you could see the lava coming out; now there is nothing like that", which can lead to think that "this is coming to an end. What you have to do is have a little patience," advises Soler.

Regarding the volcanic tremor, remember that four days ago there were a series of explosions from which the vibrations have declined, as happened on September 24, when the sonic bombs were registered that forced the rapid eviction of several neighborhoods.

Soler's thesis is that the magma had difficulties to exit through the conduit, as if it were too narrow, until it enlarged and the lava began to come out more easily, and he believes that the same thing could be happening now, with the difference of that cannot be seen with the naked eye because it does not run on the surface. "It could happen that the end is far away," he slides.

Regarding the decrease in seismicity and sulfur dioxide emissions, he agrees with his colleagues that we must wait for these "small signs" to consolidate into "a clear and sustained trend."

To all these factors, he adds the lithostatic pressure, that is, the weight of the volcano on the supply system and its possible impact on the local deformation of the terrain and on the type of lava that rises to the surface.

"It is not surprising either," he continues, that the chemistry of the gas plume varies as the eruptive process progresses and the magma feedbacks come from deeper.

"Everything is theories. The only reality is that the eruption continues. Earth science is like that for the simple reason that no one has had access to its interior. Lava is a representation of what happens near the surface", Soler reflects.

"We can not make checks. Geologists have it easier: with a microscope you do magic things. Talking about the center of the Earth is a gamble," he concludes.

06/11/2021 18:30h Canary Islands. - ERUPTION OF LA PALMA ISLAND. - DAY 49. - LOWER THE SISMICITY, THE SESMIC ENERGY RELEASED AND NATIVE ASUFRE. ON THE contrary, DEFORMATION, THE VOLCANO ON THE contrary, A LOT OF ASSHE WITH RAYS AND MAGMA. - Seismicity gives us the first joy in a long time, now it's going down and that's good news as it indicates a drop of pressure of the whole system in depth, at least that seems, since unfortunately there is still to e wait 48-96 hours no earthquake 5+ to confirm this fact.

RELEASED SESMIC ENERGY ACCUMULATED-

Right now there is a GAP or gap or lack of accumulated seismic energy released that would equivalent to a 5.3 earthquake.. a lot seems to me and if this continues it seems the system is relaxing, the energy rate emitted is obviously dropping. We haven't had a very strong seismic at the highs I set yesterday, a 4.0 which is the strongest in the last few hours near the first high and shallow, is very significant.

First max - 01:15am - about half an hour.

Now we have the third maximum this morning at 02:05h IGN and Canaria, let's see what we have, whether a big one or otherwise still relaxing as we all expect and there's nothing outstanding. In addition, tomorrow the next maximum will be 12h and 25min later (It's the lapso), at 14:30h IGN and Canaryas and 15:30h Peninsular. (Enrique)

ASHENSIONS:

The upper mouths continue to cast a lot of ash, with sporadic rays and their thunder, but the most important thing is that the wind today takes everything to the sea, towards the southwest. Don't miss this morning's Involcan video.

The appearance of native sulfur on the side of the volcano indicates a change in the dynamics of the volcano, or as they say since Involcan, a "clear change in trend":

Sigh in the volcano.

https://twitter.com/i/status/1456701783661756421

"Experts explain that to form an elemental sulfidric acid (H2S) reaction is needed." This could be indicating that the magmatic part of gas might be coming down. Ultimately, this drop in the magmatic component would result in an increase in H2S emissions." It is, a possible indicator that something is changing in Cumbre Vieja. Now, experts are asking to keep calm and not jump to jump to conclusions. "This fact does not imply an end to the eruption," they clarified.

https://lanoticia.digital/.../aparicion-cumbre-vieja...

DEFORMATION AND TREMURATION:

The deformation data at the LP03 station indicates that it has risen or inflated about 10 cm in the last 24 hours in that area, and in addition it has a little significant movement in the horizontal of 2 cm westbound and 1 cm southbound. This indicates that more magma reaches the erupting point when the pressure rises.

The tremor has been rising and now holds for the last 36 hours, although it has had a couple of episodes with very high or high explosive values. This would indicate more magma reaching the eruptive point, hopefully it's the last thing that sends from below the last 5 earthquake we had and the spasmodic tremor a few days ago.

LASTLY, AIR QUALITY

It's not good at all in the valley, at least in view of the station's graphics where you can see a lot of fine particles of ash and a lot of SO2, which has reached almost 200 micrograms per cubic meter concentrations.

http://www.ica.miteco.es/

If we look at the data of the gases emitted by the volcano, we have the measure of SO2 today, it is a little lower than yesterday but it is still very high because it is 29,000 tons daily and for CO2 about 1,850 tons daily.

MAP OF NECKLACE

The coladas advance and the huge kipuka with buildings left of Todoque just before the Mountain, has disappeared and it's history, yesterday's flow 15 has taken it ahead.... Whether it's going north or south, it looks like it's headed south.

We'll see what happens, but this time the earthquake if it seems to be going down (there has been no earthquake of 4+) and if in the next days (48- 96h) is still (there is no 4.5+) and confirms it without the occurrence of moderate earthquakes, the eruption will go down in all the parameters, though not it's declawable any report, let's hope it's just that and in 2-3 weeks we could say something like this could end the eruption, it's soon, but at least it's the first day I can say it with a little certainty (30% nothing more). Greetings. (Enrique)

07/11/2021 10:30h Canary Islands. - ERUPTION OF LA PALMA ISLAND. - DAY 49. - LOW THE LIBERATED SESMIC ENERGY, LOW THE TREMURER, LOW THE DEFORMATION AND SO2 IN THE AIR LOW TOO. IT IS STOPPING. -

Little more to say, please continue, it's decreasing its activity and all the indicators indicate it. That 4.5 from yesterday didn't emit enough energy to recover the step it was taking. The trend right now is that it's going to stop, but it's very inertia.

Do not forget that twice has changed the trend, although in those two times the energy rate did not go down like now, it was more punctual, now it is decreasing already since the last Earthquake of 5 about 5 days ago, so you can say with 70% security that is stopped. If it continues 48 hours more, in 7 days we will reach 90% safety that is stopping.

The coladas don't seem to have affected new areas in this morning's photos and are pretty much where they were yesterday. There are some new streams in the high area, but they are coming down for old coladas areas.

Well that the volcano is STOPING or BRAKING, as they prefer, although it is not finished yet, for that there are many days left, I calculate that about 2 weeks at least and it will be noticed before finishing with some trouble, I have no doubt about that.

Have a nice day and enjoy. (Enrique)

The activity at the vents continues to decrease gradually, at least visually and audibly. Residents reported less explosions and less intense degassing noises. Explosions at the vent are intermittent and no longer as vigorous as before although ash emissions seemed to have picked up in the morning again.
On the webcam, it can be seen that lava emission continues, but also seems less vigorous. Some of it forms active lava flows on the lower flanks of the cone, overlapping older flows.
Volcanic tremor has remained at similar levels as yesterday, but continued to decrease overall. Hopes are emerging that the eruption might be approaching an end although this is still too early to be certain of.
A pair of two quakes with magnitudes 4.5 and 4.6 occurred last afternoon at 5.07 p.m. at approx. 38 depth within 10 seconds from each other, but so far, there seems not to be any significant change with other parameters (e.g. eruption intensity) that clearly correlates.
It is not known what the exact significance of these and other quakes is at the moment. Whether it is caused by an injection of new magma at depth, or gravitational adjustments perhaps caused by the depletion of magma from there or something else, is speculation. It might become clearer in the future (likely some time after the eruption ends), when the data currently collected by scientists will be more complete and when models will be made that can match the various data with the observations. For now, one can just wait and see...

 09/11/2021 18:30h Canary Islands. - ERUPTION OF LA PALMA ISLAND. - DAY 52. - LAVA NECKLACE MAP- THE 15B IS ON THE BEACH FALLING BY THE ACANTILADO. ONE HORROR PEAK AND MORE STILL GOING DOWN. - Today it seems that it will be noticed that the volcano is calmer, still it does not remove that sometimes it has more active peaks, such as the tremor peak we have had at 6:30 in the morning and that has lasted an hour, where you can see it several hydromagmatic explosions in the spectrum..

One of the possible explanations for this behavior is that when going down the pressure some water has entered deep into the volcanic system and this sudden increase in pressure and tremor has been produced and something more exploded Osed for an hour, stop then come down and recover almost the levels before, but it has gotten a little lower, showing that it is slowly stopping, remembering that it has been a lot of inertia that it has been picking up in past days.

THE ERUPTION AND THE VOLCAN - it has been measured and reached 1131m high, no less (RTVE). The SO2 gives us good news, keeps going down, is high still with 18500 tons daily, deformation keeps coming down slowly, tremor low and the accumulated seismic energy rate is somewhat higher than yesterday with 70 MWh, but very much for below almost 1000 MWh in the days of most active. All in a nutshell, the volcano continues to stop... if it continues in 10-14 days it could stop, that does not mean it will stop, because it has to be considered that it should as long as we do not have new deep magma contributions that could reactivate it. -

The truth is that it is very significant that we have been more than 50 hours without an earthquake of 4 or more after the double of 4.5 and 4.6 two days ago. The last one was a 3.8 today matching the moment the tremor rose. That doesn't take away that the earthquakes are over and putting a seismic forecast for the next 4+ that could be in about 48 hours more or less in one of these three highs. More earthquakes we are going to have, it has to lose inertia, fortunately they should go less and spacing in time.

MAP OF LAS COLADAS: The 15B colada has followed its path advancing the whore of more than 1 km in 24h to reach the cliff at the height of the Beach of the Guirres where it is currently taking place in an impressive way, don't miss it l to the camera live.

On the map I made using thermal flight data you can appreciate that the current laundry is well fed with some active arms above:

- One north that has advanced about 300m to a kipuka north of the 9A just to reach a few meters from where the SPAR road (LP-213) was and about to exit the gap between 9A and 9C, which would make it go around the edge north of 9A. Not very active at the moment.

- Then there is another arm south that has advanced a bit more than 400m but at the moment it does not have a very important contribution in the southern area of Todoke over the old coladas, also about 200m above where the hole path was.

In addition, it must be emphasized that except the kipuka of Todoque that has been swallowed and the area of the estate that was between the coladas 8A and 8C, the rest of the flow is over areas already destroyed, I thought it was going south, but in the end it has doubled and it hasn't affected new areas further south. God willing it could be maintained for several days avoiding the destruction of new areas.

And I have one last southern arm of the flow above that has marched the Cogote Mountain of this flow has stopped. And don't lower the guard, above all there are more coladas, even though they seem to have little tour.

Well, now it's time for the eruption to consolidate these obvious signs that it's going to be less and more. That doesn't take away that I don't have moments of more activity, earthquakes and even some more surprises as I commented a few days ago that did the Tajuya eruption in 1585, we'll see.... What's it over now... (Enrique)

10/11/2021 15:30h Canary Islands. - ERUPTION OF LA PALMA ISLAND. - DAY 53. - DEEP SHAKES OF 4.8 AND 4.4; SPASMODIC TREMORES AND THE EXPECTED REPLY HAS ARRIVED, NEW DEEP INTRUSION IN THE PALM. - The volcanic activity of the island of Palma has stopped stopping the eruption in dry, i.e. climbed and accelerated to reach a high speed, about 300km/h and was slowing down to 200/km/h and had continued so would have stopped in a couple of d and weeks, but for now it's stopped and accelerated again, we'll see how far.

So past 8 in the morning IGN time, a spasmodic tremor announced that the magma faucet would open and it flows deeply presurizing the system again, giving deep seismicity more and more common and more intense for the reservoir magma immediately started again presurizing and it went up to a 4.8 Earthquake (initially a 5.4 degraded to a 4.6 and finally 4.8 ) and some more like a later 4.4 which has also had new spasmodic tremors.

Ultimately, it's not good news, the volcano is accelerating again, this is the tale of never ending, but nature is like this, this eruption has not ended, when it's already announcing the next. You can clearly see three spasmodic tremors (9:00h, 13:00h and 16:00h) that tell us that the magma faucet has reopened at a depth of about 37 km and it flows towards the surface. In 2-4 days the pressure of this magma pulse will reach the surface, announcing an increase in all parameters, gases and deformation in the coming days and the eruption will still take time.

I mean more magma coming, a new deep intrusion, not sure if enough or not for a new eruption, but a good amount and pressure. Most likely to take advantage of the existing conduit in the current eruption to get out, it's the easiest as that conduit has not yet closed. If it was closed or closed, then if we would have a good problem, as the probability would be shared and could open again by the same site, near the same site or even by a new site more likely at least. Let's continue, we'll see what he does.

On the other hand coladas continue to arrive into the ocean through a system of lava canals and some pipes that go down the side and with some occasional overflow that gives way to new arms and that are well fed of magmatic material by the point eruptive in where it follows growing the pyroclast cone that continues to cast a large column of ash and gases.

The tremor, deformation and gases are on the low, but now we have to wait for what will rise and how much, and hopefully it doesn't rise much in the next few days and reclaim the lower as soon as possible, it's just a passenger reparation. Until 48-72h passes to tell us if there are more intruders or not, we won't know. We'll see what happens. (Enrique)

EDITED: If the last data of 43000 tons a day of SO2 is true, it does not but confirm that there is a clear response in volcanic activity, it would be two legs, seismicity and gases, lack of deformation, tomorrow's data will be crucial for sab It's like it's going to respond, little, pretty much or much.

That's a spasmodic tremor... many tremors together indicating that the tap opens and lets go of magma that depresses and moves in the direction of the surface, you will have to think that the easiest is by the already existing conduit or path of the current eruption.
R. Ortiz told us that "The spasmodic tremor is due to multitudes of volcanic-tectonic earthquakes linking and reflecting a high-frequency band on the spectrograms. Its name comes from paper seismographs, where needles would leave band-like black spots when overlapping the map of the earthquakes."

“This is because there appears to be two lawsuits going on. One, generated by the thrust of magma that intends to rise, producing large earthquakes of magnitude 2.5 and higher. Another process would be making a push through a "crack mechanism", generating earthquakes of small magnitude but very numerous. This is because magma spreads generating tiny fractures (cracks), which break in front and close in the back, repeating the process. The problem is that this second process is very difficult to locate when overlapping Events with others and they cannot be analyzed individually
That is, the tap is opened and the magma flows through the rocks fitting deep. (Enrique)

We have to see how big the rebound is coming, a few more days or a few more weeks, that we don't know yet, it's early. In the next 48-72h he will make his intentions clearer. (Enrique)
