13/12/2021 - 20:00h Canary Islands. - ERUPTION OF PALM ISLAND. - DAY 86. - STROMBOLIAN ACTIVITY - VULCANIAN WITH A LOT OF NOISE, ROOTS, BRAMIDES, JETS, EXPLOSIONS, LOTS OF ASH AND GAS - NEW ACTIVE COLLEGE FOR THE SOUTH THAT IS IN THE LAS NORIAS AREA.

- The volcano is stopping, so many parameters indicate, but it is not finished yet and since it changed about two weeks ago the method of impulse of the magma ascension, because it makes it very difficult to know when this will end.

I have to remember that the volcano worked through a pressure magma impulse, by presurizations of the magma that pushed the magma from deep levels to the surface, generating an intense seismicity for it, but this just got mome nto, i might go back tho. Now the impulse system is another, it is because of the island's own weight that takes advantage of that conduction to drain magma along that way, so it won't stop until the conduction is opened or the reservoir of the magma is depleted.

By explaining it in a simple way, the volcano started as a burst into a pressure pipe that was rising from the depths and the water came out to pressure. But two weeks ago this changed and now it's like a waterway on a boat, where the water enters until the pressures are equal, the waterway is blocked or the water runs out or the pressure is lower and it doesn't come out at that point.

We have basically passed that the magma is pushed by the pressure under the island (able to lift it up) (the balloon is inflated) to be pushed by the weight of the island (so it is slowly sinking (the balloon fades), towards the nivs they in which the eruption is stopped when the magma is exhausted, it is usually a percentage of what is raised, although it is not usually never reached prior levels because of the material that cools in the sills or horizontal dicks).

Evidently this causes a drop of pressure in the major eruptive pipeline that causes it to be temporarily closed, giving activity pulse and also causes water entry into the same, thus the activity becomes much m Explosive ace for these furious Events because there are more gases and itch much more pyroclasts and forms thinner and clearer ashes.

I'm going to review the news today and comment a little everything with this mechanism, which causes changes, that yes the lava will continue to come out, although something colder and viscose, so the lava coladas will be something slower, higher and wide, that already paced Mos see and the videos of today.

Tremor and Ashes Show:

The tremor rises again, yesterday after stabilizing in several violent eruptive pulses with ash emission that climbed 5-6km height and a tremor that climbed up to almost 60 units of RSAM. After these pulses, we've had some quiet time for about 12h, and now it's back up, right now the tremor is roaming the 60 units of RSAM again and rising. Surely lightning has been produced and more will be produced if this level of activity continues.
And the height of the ash column, is classified as a volcanic when you exceed the 5km height of the eruptive feather, hence it is not only strombolian.
https://es.wikipedia.org/wiki/Erupci%C3%B3n_vulcaniana

EDITED: The tremor has almost stopped after the last pulse at 22.30h Canaria.. we see some hydromagmatic explosions in the conduit, it's not finished, but the exterters are starting, we'll see if the end or just another phase. -

ENVIRONMENTAL GAS AND VOLCANO:

I have no new data, except that the Pevolca says the amount of SO2 emitted by the volcano is high, between 1000 and 29999 tons daily.... what little does he tell us, since he's been like this with flat encephalogram for two weeks ago. There is no new data in satellite data as of November 11 as of now, it was going low and we don't know what happened to yesterday and today.

- UNITAD MOVIL EL PASO (99999989) [FOUND] - We have had a couple of maximum values of 2593 and 2252 micrograms per cubic meter at 10:00 and 11:00h respectively, emphasizing that we have had values above the danger threshold of the 50s 0 micrograms per cubic meter since before from 8:00 a.m. to after 1:00 p.m. - record.

- UNIDAD MOVIL LOS LLANOS (99999988) [FOUND] - We have had a couple of maximum values of 1677 and 1673 micrograms by cubic meter at 10:00 and 11:00h respectively, emphasizing that we have had values above the danger threshold the 50 0 micrograms per cubic meter since before 8:00h until a little before 1:00h. - record.

- UNITAD MOVIL PUNTAGORDA (99999991) [FOUND]- We have had a couple of maximum values of 529 and 575 micrograms per cubic meter at 11:00 and 12:00h respectively, emphasizing that we have had values above the danger threshold the 500 m icrograms by cubic meter since before 11:00am until a little after 12:00h. - it doesn't reach the record but if it crosses the maximum limit.

AIR QUALITY CONTROL NETWORK:

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

- zoom in on the palm and choose the station.

LEGISLATION: Will someone say where it says the danger threshold is the 500 micrograms per cubic meter for more than an hour... because in the Legislation, in the BOE: Real Decree 102/2011, of January 28th. Attachment I. Point II.

"BOE" no. 25, of January 29, 2011, pages 9574 to 9626 (53 pages. )

https://www.boe.es/buscar/doc.php?id=BOE-A-2011-1645

COLADAS: Follow the flow through the central trunk, but the 22 flow has diverted between the ancient coladas 3 and 4 where the "kipuka" of the dogs or island was of land surrounded by lava coladas where the dogs were and from there is going south of the coladas field in the same area that did the colada 13 something above the road of Todoque and is swallowing about 100m wide into the ocean, reaching the Norias, which is surely swallowing in e these moments. I'm sorry.

RELEASED SISMICITY AND SESMIC ENERGY:

There is less seismic energy released, there is no doubt about that, today it has released about 9 Mwh, something more than yesterday, and about 100Mwh in the last week, but certainly much less than in the days of more activity, where we reached more than 1000Mwh in 24h. Thus the curve of the accumulated seismic energies released is flattening indicating that there is no input of new energies and that it now works with the inertia it has taken in previous days.

And by analyzing something, you notice small pulse or swamp approximately every 48h for about 10 days that look perfectly, predictable behavior and therefore typically volcanic, which indicates that this is going for a while and that I have already seen or in other volcanoes.

On the other hand there is seismicity located between 6 and 9 km deep in the deepest area of the conduit, nothing more coming out of the surface reservoir at 10- 12km and which is surely related to the small presurization that has been produced ucid when water enters the system in the eruptive conduction, you can see LP03 lowering and LP04 lowering even further. This announces more hydromagmatic activity, which by the way is clearly seen in the spectrum in the form of vertical spots that are not earthquakes.

Today I have to emphasize that the THIRD Photo was sent to me by Moses and it appears in this space. Thank you Moses.
And I finish already, go post, this continues, relaxing and losing strength, but we do not know when it will finish, there is a lot of energy still down there and hopefully the open conduit that flows freely now clogged up or close well when it does and not be v uelva open it up. In the Iron passed and closed, and it did not reopen, despite the fact that there were several swampers with attempts to reopen and that they lifted the entire island dozens of centimeters once the eruption ended. But the magma didn't come out anymore. In 2013 it was the last strong swarm with a 5.1 IGN magnitude Earthquake (5.4 according to EMSC) and then it ended until today. Greetings. Good night.

A swarm started again yesterday evening but these were mainly earthquakes under Magnitude M2.0 .

Since midnight up to 07:20 there have already been 62 earthquakes.

There was a stronger M3.1 at 06:39 .

All can be viewed on the link below.

Since 21:00 Canary time yesterday, there is no volcanic tremor in Cumbre Vieja (La Palma). This does not involve an end to the eruption. On other occasions, the quake of tremor has been followed by a new increase in volcanic activity. However, this is the longest no tremor interval since the start of the eruption.

La Palma volcano eruption update: eruption intensifies intermittently
Mon, 13 Dec 2021, 23:10
23:10 PM | BY: T

After yesterday's large explosion at noon, the eruption gained in intensity, both explosive and effusive, during the evening and night. After being quieter most of the day today, it increased again in the evening, shown by the strongly fluctuating volcanic tremor signal.
Phases of strong ash emissions and lava fountains have been alternating with quiet periods when only steaming could be seen at the craters:

Ash plumes reached 4,200 m above sea level this morning, and reportedly up to 7,000 m in the afternoon, and drifted southeast. Absence of wind near the ground created very high SO2 concentrations in El Paso today, with values surpassing 2.590 micrograms per cubic meter this morning.
Lava continues to flow from the (hidden) vents on the western base of the cone into the tube system and crate breakouts in the central part of the flow field. One of the more active surface flows began to eat away one of the remaining islands of so-far untouched land in the area south of Todoque and east of Las Norias, as can be seen in the aerial drone image attached.

The number of quakes has again increased in numbers: During the past 24 hours, there have been 4 quakes of magnitudes 3.0-3.4 and 46 quakes between 2.0 and 2.9. Most of these occurred at the shallow layer around 10-15 km depth while only very few ones occurred at the deeper layer of 30 km or below.
The decrease of seismic activity in the deeper layer might indicate that magma supply from that area is less now than during previous weeks when lots of magnitude 4+ quakes occurred there, but this remains speculative.
No significant changes in deformation has been recorded.

14/12/2021 - 21:00h Canary Islands. - ERUPTION OF LA PALMA ISLAND. - DAY 87. - TENSA WAIT - PRESSURE LIGHTLY, DEFORMATION ON LP03 IN DRIVING, CLIMBING SISMICITY LIGHTLY AND GAS IS HIGH. - STOP OR STOP ? - The truth is that I would like to say that it's over, but I don't care about a hair and previous experience and eruptions tell us that the volcano has the final word.

If we take the Teneguía, this one just suddenly, but if we take the San Juan, I stopped for a few days and then opened new mouths, among which highlights the mouth for which they lower the coladas that formed the Delta of San Juan. One of cal and one of sand. But let's go with the data there and their analysis to see where they're heading:

GAS SITTED BY THE VOLCANO

I start by the gases, according to the satellite, yesterday's gas pulse has passed, as seen in the image of the post, where you can see what it emitted yesterday over Africa, according to the OMPS a total of 3380 tons of SO2. Looking for more data and came across this:

DAY 87: - SOURCE DATA UNSECURE-

1290 tons of SO2 a day
2400 tons of CO2 a day
493 million m3 of lava


source: https://twitter.com/vleeskr.../status/14...5226805249...

And it is that when the data is scarce, these things happen, facts appear that one no longer knows whether to trust them or not. They're sometimes less rare in the view of the satellite photo, but it indicates to me that CO2 would give problems, as it's happening, normal and totally logical thing.

TERROR AND SISMICITY:

I have to explain that the measure of the tremor is made as the Measure of the Amplitude of the Seismic Noise or RSAM in English, and of course, not only the sound of the volcano is recorded, also the seismic noise of other sources, in this case a small peak pr Oduced by the noise of a 7.3 Telesism in Indonesia in the area of the Sea of Flowers.

But then, what noise do we record as tremor? , for the sound of the magma flowing, like the sound of a mountain river, the magma makes noise and that is what is recorded. We took a 24-hour stop of the magmatic noise of the volcano, which barely has a caudal, so the magma of the ducts has almost stopped completely. The cause is complicated, but it may basically be that the pipelines have been closed when the pressure is lower, that they have blocked, or that the magma that came from below is just finished.

SISMICITY, SESMIC ENERGY AND DEFORMATION:

But as you know what's going on down there, we have two keys, seismicity and deformation. The seismicity, when lowering the tremor, can again locate earthquakes of less intensity, in beginning between magnitude 1.5 and 2 and allows us to appreciate that in addition to the seismic swarm ball where the magma presurates in its different reservoirs, the most energetic with 2-3-4 magnets there is scattered seismicity, magnanimities 1.5-2.5 that indicate that, as the efforts are scattered around the ground surrounding this active area.

So in the last few hours has slightly repaid the seismicity in the area of the reservoir that has pressurized a bit and then has done it clearly in the conduct, you just have to see the deformation in LP04 and LP06 that goes up a little and LP03 that sub and almost one centimeter. Tomorrow I should follow this trend if it doesn't break the stamp and we have another pulse of activity with a lot of ash. In the deep area, however low is what indicates us a small contribution of magma from deep levels to more shallow reservoirs. This tells us that the material continues to move in deep. An Earthquake also indicates something, but it moves little at the moment.

In terms of the surface area, right now the most important seismic activity is concentrated, both at the entrance to the reservoir at 10-14km, with two earthquakes at 15km very prominent:

SPECTROGRAMS AND SISMOGRAMS

One would think that you don't see things, but there are very interesting things, the first thing are hydromagmatic explosions in the pipeline, which should produce some other Earthquake in that area as recorded at TBT station at 12:50h, 13.15h, 1 3:22 pm, 1:48 pm, 2:35 pm, 3:20 pm, 6:15 pm, 7:40 pm... and those who go out..

Another thing you see are small earthquakes that only mark low frequencies, type VT or even LP(the one at 20:25h) but I don't see the tail well and are triggered by magma movement like the one at 19:10h or the one at 20:52h that are still there without locating.

And the most interesting thing, squeaks and whistles of volcanic slips that are marked on the seismograms as horizontal lines, in some cases as discontinued strikes as for example at 17:05 to 17:15h to 17Hz or a little before 14.14 to 1 5:32h to 18hz, coinciding with an explosion hydromagmatic and indicating that depressurization of gases. To make an analogy of this, it's like when the teapot or coffee maker whistles with the steam pass.

VIDEOS OF THE COLLAPSE:

And these were the coladas this morning, the 22D has advanced a little further towards the norias, about 50-70m since yesterday afternoon and has stopped just at the height of the restaurant "La Mariposa", but they continued to flow slowly, both on the surface and inside lava tubes, just like seen in the following IGME video:

CONclusion:

Everything indicates that it keeps losing energy and still stopping, but it hasn't stopped. Now it's pressurizing and water enters the pipeline, (LP03 should go up), but what we don't know is if it will have power to reopen the pipeline and release another pulse with lots of ash and lightning, (series lighter and chopped ash, even white echo, in the presence of water and be cooler and viscose) as it should be logical, or otherwise it will end up completely and shut off because it lacks energy. It might take hours or days but I think I should at least have a couple of them.

Therefore, we have to wait between 2 weeks and a Month and we can give it to the end, that is as long as we don't have new deep contributions (It would be intense deep seismicity). I wish so but I don't care. A lot of encouragement.

Pevolca update on Wednesday, December 15th at 14:15 pm:
➡️In order to be able to say that the eruption process is finished, the registered data and visible signs must be maintained at current levels for 10 days.
➡️There is no constancy of lava flow from the main cone.
➡️In case of ash emission, the provision of the penalty would be south-east, which would be an unfavorable scenario for the operation of La Palma airport.
➡️Currently, air quality is unfavorable in Los Llanos de Aridane. In the rest of the island the levels are between reasonably good and good.

15/12/2021 - 20:45h Canary Islands. - ERUPTION OF PALM ISLAND. - DAY 88 - (86+2). - THE VOLCANO STILL STOPS, A SMALL MOUTH (MAX 3.4 TO 15 KM) AT THE ENTRANCE UNDER THE DRIVER OF THE SURFACE RESERVE, AND JUST AFTER SLISSING. -
The slipping shortly after the 3.4 Earthquake has reminded me of the noise a truck makes when it stops, an onomatopeya type... PSHHHHHsHHHHH... what is gas that sounds at a frequency of 28hz.. going up almost 30Hz then down to 26Hz.

For now it's stopping and we're on the right path, but we have to wait, each day that passes, is a day that we're approaching the end of the eruption. A couple of weeks will be enough to be almost safe, 1 month, and it will be able to certify that it has stopped (Remember that in the eruption of San Juan, which started on June 24 in Duraznero, then stopped on June 8 and reactivated at the same point on June 30th and opened new mouths and tails of lava 22 days after stopping until the end of the eruption on August 4th that went down the valley of Aridane.

Between the middle of June 8 when the mouths of Duraznero stopped, a new mouth of Llano del Banko was opened 3 km and hard until June 24th, forming the Delta del San Juan.

In addition, on July 12 there was the opening of a third point with a violent freatomagmatic eruption in the Hoyo area black which lasted until June 26. There was no activity between July 26 and July 30).

https://es.wikipedia.org/.../Erupci%C3%B...%C3%A1nica...

Knowing he did this, you need to be couthed and not sell the bear skin before hunting it. We all want it to stop, but the last word has the volcano and now the best thing is that it continues to deactivate. This is seen in several parameters.

THE GAS AND DEFORMATION:

When you don't see, you have to see how the patient is breathing, like breathing and inflammation, so therefore no longer breathing almost and the inflammation of the island is calming down, which is good, the wound is healing. SO2 is at very low values, they say 5 tons daily, compared to previous days values, it has almost stopped. and let it continue.

SISMICITY SUPERFICIAL:1-3

The closure of surface cracks and cracks, as well as the emptiness of some and the non-presence of tremor allows to locate those superficial earthquakes of which I talked about 1-3 km with several localized and fortunately not concentrated, indicating disp ransom of efforts and closure of fractures, that not concentration like when it's going to open fractures.

DRIVING Earthquake: 4-9km

By closing the emission point if small presurizations occur, some seismicity has been produced, but it is not noticeable, indicating that it has no strength to open at the moment in the conduct, which is seen confirmed with the data of LP03 that n or it has risen, better know it has calmed down more and where only one has been located in the last 24hrs.

SISMICITY IN THE SURFACE RESERVATION 10-13km AND DEEP ACCESS TO THE MAGMA A: 14-16km. We have had a little swamp, which does not seem of opening, but is something different, seems rather something that closes and has produced that seismicity because it was too early to close, as if the magma was in the opposite sense, returning to your place for the lowering of pressure down to running out of power. The slipping or noise in EGOM after this Earthquake is also different, it's not a pressure increase, rather it's a pressure relief.

SISMICITY IN THE DEEP RESERVE 35-40km AND DEEP ACCESS TO THE MAGMA A: 38-42 km.

TERROR AND MORE...
There is no noise of the magma anymore, so this one does not move hardly, it stops and what remains in many pipes, it crystallizes and hardens in them forming dicks, walls and python or "necks", like the thousands we see on the islands and which are one of them signs of identity of the islands, as they are hard and erosion dismantles the materials on the softer sides highlighting the landscape, one of the most well-known, the Rocks of Garcia in the Canadas del Teide, the Rock Nublo or the Rock of the Mu but there are many more....

CONclusion:
I'm not going to put a map of Coladas, it's cloned to yesterday, and now yes, everything indicates that it's over, but I can not throw the bells and fly, and give it for finished, it has come out palm and singular, where the known does not work as it should and you have to wait air by at least at the end of the year or even something else, as the laundromat gets colder, the cone continues to collapse on itself and the people evacuated who may are going back home and will recover part of the life that was lost to start over.

Easy to say, doing it will be hard, very hard, especially for those who lost everything. Cheer up palms. Good night.

Continues eruptive activity on the island of #LaPalma (16-12-2021 09:00 UTC)

➡ Since the last statement, a total of 56 earthquakes have been located on the island of La Palma, one of them felt by the population.
➡ The maximum magnitude recorded is 3.4 (mbLg), corresponding to yesterday's Earthquake at 15:09 UTC, at a depth of 14 km. The minimum magnitude of the localized Earthquake was 1.2 mbLg.
➡ The localized seismicity continues under the central area of Cumbre Vieja in the same areas of the last few days, with dispersion. Most of the earthquakes (39) are located at depths between 8 and 17 km. 11 earthquakes have also been located at a depth between 33 and 40 km and 6 at a depth between 0 and 5 km.
➡ Apart from this localized volcanic-tectonic activity, and coinciding with the disappearance of the volcanic tremor, low frequency signs have been detected in the seismic stations interpreted as LP Events.
➡ The broadness of the tremor signal in the last 24 hours has been maintained at levels near the preliminary period.
➡ The island's GNSS permanent stations network shows no clear trend in deformation of stations closest to eruptive centers. The slight deflation previously observed has been stabilized in the rest of the seasons.
➡ In view of the image calibrated at 08:45 UTC, no broadcasts are appreciated.
➡ The height of the cone is measured getting a value of 1.122 m. above sea level.
🌋 The IGN continues its presence on the island, where the CAVE (Center of Attention and Eruption Surveillance) has been established, maintaining, denensifying and improving the surveillance network.

16/12/2021 - 21:30h Canary Islands. - ERUPTION OF LA PALMA ISLAND. - DAY 89 - (86+3). - 3 DAYS OF REST ON SURFACE AND NO EMISSIONS OF PYROCLASTES OR NECKLACE, AND STILL STANDING IN DEEP. - LIL DEEP SWIMMING. - PATTERN WITH REPUNTS EVERY 2 DAYS MORE OR LESS- Well, we'll stop that it's not little, today the most prominent part, the graphics with the swamp marked, both in seismic energy released over time and in seismicity with depth and tie mpo and in both cases you can see the pattern, but you can see something very curious, the activity as I said yesterday is migrating from the surface area to the deep area as the eruption calms down and ends. Well that's it, it's not little.

The most prominent seismicity is the earthquake of 3.4 in depth of that swamp which indicates a slight pressurization and which indicates deep magmatic movements, we do not know in what sense whether to load or unload, but one thing is clear, it increases slightly mind the pressure of the deep reservoir.

The deformation is maintained, slightly climbs in the eastern part of the island on LP05 and MAZO of the deep reservoir due to the swamp or small presurization it has had, the rest of the system relaxes, there are even more superficial earthquakes.
CONclusion:

Ultimately, let it continue to stop and hope to have a Christmas and New Year's Eve with many things to celebrate, including the end of this Natural disaster, a name that politicians avoid and that shouldn't. Things must be called by their name. Natural Disaster.

Volcanic Risk Zoning is..... insufficient and the preparation for this disaster has been almost zero on the island, but except the Pevolca Plan itself of 2018 (which needs to be reviewed and a lot) and the Canary program, a window in the Atlantic that the Involcan has been doing education for years Volcanic for the decrease of the volcanic Volcanic risk in all municipalities, there is almost nothing else. Volcanoes are unknown to canaries and live in volcanic islands, more than half, active and erupted in the past 500 years.

DECREE 112/2018, of July 30, for which the Special Plan for Civil Protection and Emergency Attention for Volcanic Risk in the Autonomous Community of Canary Islands (PEVOLCA) was approved

http://www.gobiernodecanarias.org/boc/2018/154/002.html
http://sede.gobiernodecanarias.org/.../boc-a-2018-154...

A lot of things have to change, that's clear, the first is to think that this will happen again in the Palma and other islands yes, yes or yes. We don't know the exact date, but many canaries alive today will see the next one from their window, that's for sure.

The palm of the PEVOLCA map says it all... not suitable for this eruption... And the coladas from previous eruptions? they don't even mention it. It's a plan at the convenience of politicians, not the people and much less of the volcano. We are fixed. (Enrique) -

Seems like a normal process, by closing the conduit, now it continues to pressurize something in depth.. we'll see how far this little bump goes. As long as I don't go from one of 4.5 or a half dozen of 4+ down there I don't worry, something stronger if it would disturb me and I would already start thinking about a new contribution. Until this, tranquility for a moment and especially if it stops. If it continues a week with a lot of seismicity, it wouldn't be good either. Much encouragement. (Enrique)

Continues eruptive activity on the island of #LaPalma (17-12-2021 09:00 UTC)

➡ Since the last statement, a total of 96 earthquakes have been located on the island of La Palma, two of which have been felt by the population.

➡ The maximum recorded magnitude is 3.5 (mbLg), corresponding to yesterday's earthquake at 22:29 UTC, 36 km deep. The minimum magnitude of the localized earthquake was 1.1 mbLg.

➡ The localized seismicity continues under the central area of Cumbre Vieja in the same areas as in previous days. The earthquakes are mostly divided into two groups, 46 of the earthquakes are located between 8 and 16km deep and 47 earthquakes at a depth of more than 30km. Also, 3 superficial earthquakes have been located in the area, with a depth less than 3km.

➡ In the last 24h, volcanic tremors continue without being observed in the records, maintaining the seismic noise in levels next to the pre-erruptive period.

➡ From the cessation of the volcanic tremor signal on December 13 at 22:20h, low frequency (LP) events continue to be detected in addition to localized volcanic earthquakes.

➡ The network of permanent GNSS stations of the island does not show significant deformations that can be associated with volcanic activity.
➡ In view of the image calibrated at 08:45 UTC, no broadcasts are appreciated.

➡ The height of the cone is measured getting a value of 1.122 m. above sea level.

🌋 The IGN continues its presence on the island, where the CAVE (Center of Attention and Eruption Surveillance) has been established, maintaining, denensifying and improving the surveillance network.
