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.

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.

- 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.

THICK OF THE NECKLACE

https://eltime.es/.../37047-35-metros-en-todoque-60...

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.

Its only 07:50 and there are nearly as many earthquakes as the whole 24hrs from yesterday.

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.
