02/12/2021 20:15h Canary Islands. - ERUPTION OF PALM ISLAND. - DAY 75. - PRESSURE RISE IN LP03 THE MAGMA ARRIVES AND LAVA FOUNTAINS REACH 500 METERS HEIGHT IN THE NEW DIQUE. - The new pulse of lava seems to begin to reach the eruption zone, the increased pressure with a drop in the water content makes it produce less ash, but instead more gases come and generate more pyroclasts that come out of the mouth and presents the strombolian activity mainly, although it is also still coming out of something for the old principal. The cone grows evidently and as it continues, it will be taller than the main one in a few days.
SUNSET TODAY AND THE PIROCLASTS CHORRO.

Yesterday making the map of the Cone area that is brought, with several drone flights and other data, you perfectly appreciate the new parallel dique that was activated a couple of days more north of what was causing the previous eruption and that t it seems like yesterday that some activity has, The scheme is rude, but it looks very well as the material is coming out more or less, in specialized mouths, from very liquid washers, passing through the strombolian mouth that produces explosions and sonic stamps and ending up by the gas chimneys they throw ashes and pyroclasts, and that are not always jet or plane type incandescent, like last night and that include freatomagmatic
Events.
VICENTE SOLER CHRONICLE - YESTERDAY:

The truth is that this scheme of another so I dedicated it to myself when I saw the images, but I like to see that there are people who agree with me as I said yesterday Vicente Soler. Couldn't agree more, the chronicle in a stunning setting.

Saying that the cone continues to grow and in the next few days it will cause problems to go filled the vertigo bowl, the overflow will not only be by the north flank, but there could be some by the south flank, as we are very close to the change of the vertigo and if you fill one little more will be a matter of time. In the area immediately below the cone you see new overflow more north that are margining the north flanco of the coladas field and that have already passed the road of Tacande, expanding in 50-70m the coladas field we will see if they follow or se Father.
What is clear is that from that position they are about to jump from a vertical basin and surely in the next few days a new lava language will be formed much further north, about 300m from the current one, but which will result in the area of the polygon a l the time from the electric transformer to half buried that is still seen in the 19A flow
.
Coladas today run through the central area, with more contributions through the 19B laundry area going south of the old polygon towards what was Pedregal. He has advanced about 300m from yesterday, which is under control.

In addition, the lava comes out with an important rate or volume, so that it drags parts of the cone down through the lava canals by plucking them, which is seen very well in the following video:

In this post I have put a scheme of how the activity has been before the eruption, a retrospective look at how it was warning us the volcano that was being prepared, slowly, with few earthquakes, but with a firm step and little by little as is would have happened since the deep area to the surface. Then at the end you see the seismicity of the different reservoirs, the upper and lower, and in the last few days even what seems like a small intermediate reservoir.
SISMICITY AND ENERGY:
The number of earthquakes has decreased, it seems that this recount is passing, the most notable in the last few hours is the 4.2
Earthquake of the reservoir above 10-12km from this early morning and which indicates a loss of pressure or concentration of pressure not being able to move forward, it seems sad, which is good news.
EDITED: Well it looks like it's going to be pressure concentration, an
Earthquake at the time of editing this post.

Tremor, GPS DEFORMATION, AND GAS
The tremor is in intermediate values between 30 and 40 units of RSAM with many hesitations and pulse denouncing an important activity that highlights the degasification of this new magma pulse that is coming. By increasing the pressure in the conduit, as seen in LP03 and lower the pressure a little on the upper reservoir as seen in LP 04 and LP01 indicates that the road of magmatic material is open and flowing, which is always a good news, because if there is no seismicity it would indicate that I am not looking for new paths.
EDITED: Well it's still quite pressurized and pushing, let's hope it loses pressure before the next contribution, because otherwise the surface seismicity at 10-12km will continue to rise.
By the way, there is no data on SO2, it has stayed at 15,000 tons a day from several days ago and we don't know anymore. I don't know why the PEVOLCA in his appearances has closed the faucet of this information without any kind of explanation, leaving us blind once again. Del de CO2, I'm not saying anything anymore... which would also be necessary. From mineral analysis to know how magma develops, you're welcome. It's an informative blackout in every order. Then in front of the gallery put 1 seismic station on the island (I have not seen anything like it in any volcanic crisis, half a dozen or a dozen would have been fine), some low resolution graphics, retouched and a couple of cameras to satisfy the perso nal and ready.
And what can we expect now? - This report of contribution again pressurized magma will end in a couple of days and will again lower the pressure in the eruptive conduct, provoking two things,
1. - A new in-depth magma contribution, which de facto is already observed in LP06 that goes up slightly, MAZO remains, but above all LP05 low again, indicating the movement of new deep magma from that area, so we will have new sis deep micity shortly with a reaction that culminate with a magnitude 5+ seismicity in 2-4 days as much as possible. I miss gravimetries again. to confirm this.
2. - The drop of pressure from the eruptive pipeline after the peak we haven't reached yet will repeat the process of water entry and repurposing of the intermediate camera. History repeats itself several times already.
And then to finish it off, today we have a new moon on
December 4th with an alignment between the sun and the moon that will give enough effort and the seismicity will be evident. The tide is of maximum coefficient of 101 which without being exceptional, it is very high and we will notice it very clearly. The high tide hour these
Tides are around midnight and noon in Palma, we'll see if the higher-magnitude earthquakes coincide or not:
DAY 3 - 00:03h and 12.23h
DAY 4 - 00:47h and 13.10h
DAY 5 - 01.38h and 13.58h
I encourage the palm trees, good night, today they sleep peacefully, some strombolian explosion, but more calm seismically speaking for what I think today will let them sleep, in a couple of days or so things will be different. (Enrique)
