The eruptive activity continues on the island of #LaPalma (24-11-2021 09:00 UTC)
➡ Since the last statement, a total of 72 earthquakes have been located in the volcanic reactivation in the Cumbre Vieja area, 5 of them felt by the population.
➡ The maximum magnitude recorded is 3.8 (mbLg) in connection with today's Earthquake at 4:44 UTC, with a depth of 35 km.
➡ In the period considered, 48 earthquakes have been located at a depth of about 30 km, the rest of the hypocentres of the period are located at a lower depth, in the surroundings of 12 km.
➡ The width of the volcanic tremor signal continues at low medium levels.
➡ The island’s GNSS permanent stations network shows a slight deformation southbound at LP03, which is the closest to eruptive centers. In other stations, slight deflation possibly related to deep seismicity has been stabilized, except in LP01, which continues to be recorded.
➡ In view of the calibrated image at 08:45 UTC, an estimated column height of 4,300 masl, and a scatter cloud in the east direction.
The IGN continues its presence on the island, where the CAVE has been established, maintaining, densifying and improving the surveillance network.

24/11/2021 21:00h Canary Islands. - ERUPTION OF LA PALMA  ISLAND. - DAY 67. - LOW PRESSURE, WATER ENTERS THE SYSTEM AND THE RESERVATION AT 10-13KM IS PRESSURED. STOP IN THE DEEP SISMICITY. - Let's see if this time we're going to a slowdown or it's just obvious, today it's too quiet for my taste, seismically speaking, downward tremor and downward deformation, SO2 almost like yesterday, but with a lot of uncertainty in the measure, but don't believe it, I think the eruption in the cone is about to change again.

SESMIC ENERGY: In the last 24h the strongest Earthquake has been a 3.7-3.8, this leaves us the energy at 25 MWh in the last 24h, after yesterday releasing more than 600Mwh in 24h. The truth is a little mosquitos, it can't stop so suddenly, I'm very afraid it will let us know in 24-48h what's coming in the form of a 4.5+ Earthquake, possibly 5+, and that it will tell us where the shots are going.

The appearance of volcanic sliders on the Gomera sensor and I fear much that it is the noises caused by water entry into the system that sounds like the pressurization caused by water entry in the magmatic system. This is why I have to explain a few concepts of magma:

WHOSE MAGMA IS SOLID OR LIQUID DOES NOT DEPEND ONLY ON TEMPERATURE, THE PRESENCE OF WATER AND PRESSURE HAVE MUCH TO SEE:
“It is called solidus point at the temperature at which a rock and liquid point begins to melt at the temperature at where the fusion is total.” Both the presence of water and a reduction in pressure can lower the solidus and liquid points of a rock, facilitating the formation of magmas without increasing the temperature."

https://es.wikipedia.org/wiki/Magma

AND HOW TO MIX WATER WITH MAGMA: At great depth and temperature, the water becomes supercritical, contrasted and measured already in a well in Iceland, with properties that do not have to do with what we normally know, it is not va by, nor is it liquid and their step from one to another does not exist, does not require energy and therefore causes an increase in its almost total solubility with magma.

SUPER CRITICAL WATER.

https://es.wikipedia.org/wiki/Agua_supercr%C3%ADtica

THE CONNECT, ASHES, DEFORMATION AND TREASON:

And this about the water that affects us? -Dense cold water, enters when lowering the pressure of the magma and gets heated, lowering its density and rising, and changes the initial properties of the magma, making it deeper liquid and less dense and therefore eases its climb, but when going up endo, comes a time when the pressure in the exit pipe area, very close to the surface as the vapor turns into gas and helps boost the magma faster in the mouth area of pyroclast and gases. In fact you have to think that a magma can expand 1200 times its size, so that 1 cubic meter of magma to 10-12km becomes 1200 cubic meters when coming out of the mouth of the volcano, lowering its clear density is and causing an effect like the descent of a bottle of champagne continuously.

This causes several effects on the volcanic cone, an increase in pressure in the exit conduit (surely rises LP06) and that increase is followed by an increase in ash emission, which will come out more stung, faster, with more noise and some explosion Zion increasing the tremor and by if it was a little accompanied by lightning and with more water, so it will surely brighten up a little color. This is what I think is in store for us in the next few days.

NECKLACE MAP:

The 17D flow seems to have stopped, the Fajana Norte formed by the 17C flow barely carries contributions but has grown up to 5 hectares, occupying 350m and getting 150m into the sea.

Instead of back, higher in the flow 17 there are news, several overruns have been produced, one north that has not advanced much giving a new flow 17E, which does not seem to advance much, but do not take your eye off, because if it continues, it would go by the edge north of the 17D affecting the remaining stretch between this flow and the 10B towards the Laguna Mountain.

On the other hand, in the area between 17C and B there have been two overpasses, one south between 17A and 17B and another going north of 17B and both in the unaffected area between 9A and 9C, form that the north goes south and meets with the other, and that go down with almost all the magma caudal towards the ocean and to continue so will form a new Fajana about 350m-400m south of the north Newly formed and to about 600-700m of south Fajana.

And for those who haven't noticed it, the coladas are going further and further north, although sometimes some arm is formed that goes south, but it is usually stopped when traveling a kilometer because they are usually overflowing of lava canals. By the way, in some areas there is already a thickness of about 40-50m of coladas, a burrad.

CONCLUSION:

The volcano lifts the foot of the accelerator, now we have to see if it steps on the brake or is it just that, it has lifted the foot of the acceleration. But it goes fast and has a lot of inertia, I think it will get more bravo with the water that is entering in the next few days, more ash, explosions, lightning and coladas and extra to say with what we have left volcano for a while... several weeks at least, but it's months..... Hard Iron eruption about 5 months, hope this one doesn't last that long, although it's been a long one. The record breaking is 84 days... and I think it's going to happen with a slump, hopefully I'm wrong and it doesn't come, but I see it hard. Lots of cheer and good night..

P.S. - I have a family engagement tomorrow and I don't know if I'll get time to post. I'll try it anyway, especially if there's something new from mobile. -

PD2: The map is taking me too long, hours... don't believe it, it's not easy, that's why I can't put it every day, though I try.
