Wow!

11/12/2021 - 22:00h Canary Islands. - ERUPTION OF LA PALMA ISLAND. - DAY 84. - THE ERUPTION LOSES INERCIA DAY BY DAY, BUT DOES NOT INDICATE ITS END CLEAR FORM, LOWER EVERYTHING. - LAVA NECKLACE IN THE FAJANA. - The eruption continues but, everything goes down, we go for each parameter little by little:

SO2 show:

today it is 380 tons a day according to the satellite, yesterday it was 653 and the day before yesterday in 1826-1983 tons a day, the highest of the last count, but it has had lower values.

HORROR:

It has been down to 17 units of RSAM, but now in the last few hours it has gone up slightly to 19. He keeps throwing lava, which reaches the fajana through the tubes and lava canals, although it seems to throw less caudal.

DEFORMATION:
The east and south area of the island is slightly inflated, (LP05, LP06 and LP01) Mazo is maintained, indicating a small deep pressurization yesterday, while it continues to deflate in the west (mostly LP04 and less LP03) and the conduction, so follows pe laughing pressure, to what water comes in and the steam content increases, but the pressure doesn't rise like other times when it's evacuated by the chimneys and open pipes in the area of the pyroclast cone.

SISMICITY:
Yesterday we had a small pressurization at the base of the upper reservoir (10-14km), in the inlet drive area in last last highlight last night.

And then we had a very deep one, just under old summit, in the magma entrance driveway from the bottom.

These two points that are like valves or passage keys and if they are noticed is that the magma flows around with difficulty, but it flows, which is not very good news, let's hope that it's little what flows seeing its magnitude, and that this will end.

SESMIC ENERGY:

The accumulated seismic energy rate released continues to decline and tend to horizontally for 9-10 days, which is good news and to follow, that is, it has been 10 days slowing very obvious and losing inertia or speed. I hope it continues like this.

ASHENSIONS:

A steam feather, emitting ash sporadically rises above the volcano to a height of about 2000m that spreads westward. As the pyroclast cone continues to collapse and crumble slowly due to the low pressure that keeps coming down.

GAS AROUND - AIR QUALITY:

It's not good, one of the causes is all these chimneys and open holes that comes out of everything, right now the station of the llanos exceeds 400 micrograms per cubic meter, and the one of Puntagorda has reached 446 micrograms by cubic meter at 17:00h. The best way to go!

LAVA NECKLACE:

The 22A lava flow continues to fall down the cliff and has advanced down the fajana about 250 meters south and about 200 meters west, partly over the ancient coladas we already had before. There is very little information. These are the only videos I found.

And I finish today's chronicle with a few images of the 112 and the IGME drones that are impressive.

Much encouragement to the palm trees, it's the longest eruption of all history... and I don't want to say anything, but we don't need it to be longer and it could be over.. Good night. (Enrique)

Hornitos between the degassing of the cone, formation of hornitos 3 to 5 meters high with a central outlet hole of the spatter. Deep empty lava canals can be seen with jameos of roof collapse of the canals.

The signal of the tremor has changed substantially and for that reason, the volcano has reacted immediately.

Perhaps it is warning us of substantial changes in the eruptive parameters, in the next few hours.

It seems that the pressure drop in the volcanic conduit is causing the conduit to close and clear, the pressure accumulates and then explodes more anguish, it's another step in the pressure drop of the volcanic system. I have to say it's just the first step to finishing, but we don't know if it's a transient or total pressure drop, we'll have to wait and if these explosions are spacing out, it would indicate it's stopping. Wow some can be strong, be careful. (Enrique)


The tremor chart shows how it stops after each pulse... (Enrique)

18:00 this evening.

The volcano has been pulsating again with sporadic explosions and the sound of the jet engines .
