2021 islands canary volcanic activity

Volcanic activity in Canary Islands 2021
31/10/2021 21:30h Canary Islands. - ERUPTION OF LA PALMA ISLAND. - COLADA 13A IN THE SOUTH AND MORE LAVA FROM THE VOLCANIC CONO. - The lava has continued to advance on the fronts of the colada 13A, in the delta area and higher next to the Norias, fortunately occupying less expansion, but moving 450m since yesterday on the southern edge of the Colada and roasting the Norias and forecasts Ibelmently will follow towards the delta or la Fajana in the next few hours/days, otherwise stop before the supply is cut off.

LATEST VIDEO OF THE NECKLACE:

In the volcano, the supply appears to increase the material output in view of the continuous overflow of the lava canal - lava tube that can be seen perfectly in IGME videos, forming waterfalls, wells or small luges like marmit giant ace, and lava sinkers that gets into the volcanic tubes.

LA ASH: The emission of ash continues to complicate life in the Aridane Valley, be careful as the PM10 particle is very intense this afternoon with values above 200 micrograms per cubic meter, although other values present v Moderate lights around 50 micrograms by cubic meter, including SO2, which must smell like mode.

NATIONAL AIR QUALITY INDICATE: - Zoom in the Palm and see the different stations.

VOLCANIC GLOSSING:

Some today at that time of Earthquake you will have heard a squeak or buzzing, like the one that makes water in pressure pipes especially when it passes through a tightening like a tanker valve or step key. This "volcanic gliding" that generates the magma fluid by a narrow step is well known in the Etna, it usually announces a paroxism or a higher volume of lava that will be emitted into the cone for tonight.
In fact, this phenomenon has lasted a little less than two hours and the frequency is seen as decreasing from 26Hz to 24 Hz, indicating that the pressure has gone down after the Earthquake, surely because the magma flows better and at less speed when opening more the conduct. This is very well reflected in a tremor reduction as the magmatic duct system generates less noise.

THE Volcanic Sliding.

https://www.bbc.com/mundo/noticias/2013/...wGxnmq2Bjs

This decrease in the tremor will surely be accompanied by a decrease in the amount of dissolved gases in the magma (mainly water vapor) and thus a decrease in the number of ashes emitted and sting of them into the circulation r better the magma for the ducts.

Therefore, although more magma is coming according to these signs, the magma comes out better by the exit pipes of the volcano cone and it seems to interact less with water, which is causing the loss of explosiveness. Tonight will be calmer in priori. (Enrique)

What to do during a VI intensity Earthquake? 👇
➡ Keep calm and stay indoors while the Earthquake lasts.
➡ Protect yourself under a strong table. Stay away from windows and any object that may fall.
➡ If you're on the street, stay away from buildings, walls and electrical posts.
➡ If you're driving, stop in a safe place, turn on the emergency lights and stay inside the vehicle.
➡ If you're in a public area, protect your head with your arms or guard yourself under the seats or tables.

01/11/2021 10:15h Canary Islands. - ERUPTION OF LA PALMA ISLAND. -LOT OF ASSH, BAD AIR QUALITY AND NEW SOUTH ARM ON THE 14TH COLLAB NEXT TO THE RJADA MOUNTAIN. -

The screenshot says it all, those yellow colors are due to SO2 gases in the atmosphere (15,000 tonnes per day according to the latest data) and the particles suspended (very high in air quality, over 200 micrograms per meter the cubic). This ash has fallen all over the island, including the telescopes of the Rock de los Muchachos, the airport and in the vicinity of more than a meter burying everything.

Link to the live camera of the photo:

Link to air quality. Zoom in on the Palm and click on the measurement station:

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

The composition of the ashes, was indicated to us yesterday Isaac, that in the Tajuya area it could be checked as the ash that fell during the first hours was of a different composition, in the color you could see, the one below more gray, the one above, more brown. This is certainly due to greater phrathomagmatic explosiveness, Isaac tells us, and I totally agree on this. The chemical and mineralogical composition of magma and ash continues to evolve.

The volcano continues to vomit a lot of material, both ash and lava coladas that go down the slope and cause new overflows of canals and lava pipes. One of those overflows has occurred near the Rajada Mountain and although it has not affected the cemetery, producing more westward, if it has generated a new arm.

This new arm will be the new colada 14, which as I say has developed from the area of the old colada 4 southward just below the Rajada mountain where the north is the cemetery, to the northwest of the same is seen coming out the very hot magma and very fluid moving quickly, about 600 meters already about 100m north on the parallel of the Jose Pons la Jurona trail and that has been divided with two active fronts heading towards the ocean.

He has made a lot of progress tonight, provoking new destruction. I leave you the picture of today's flight at 8:30h, then I'll post the map.

The volcano continues with a seismicity that has gone up after a pause after yesterday's 5.0 and returns to charge. The tremor is still high, but less than yesterday, coming down and deformation remains, recount a bit on LP03 and LP04 and lower a bit in MAZO. The pressure also therefore holds on.

Today we will be on the lookout for the coladas and the collapse that will be in the cone, although I do not rule out some felt sismicity, waiting for tomorrow that everything points to that it will be a day moved again with earthquakes felt throughout the island in view of qu and match both patterns, the most likely hours are:

- Patron of 36h - maximum day 2 from dawn to 6-7 am IGN and Canary time for the time change), 7-8 pm Peninsula.

- 3-4 days pattern - maximum day 2 pm to that of 19-20 pm IGN and Canaria time due to time change), 20-21 Peninsula hour.

We'll see if we get it right or not, tomorrow a day full of noses is presented, enjoy today that in theory it will hold more calm seismically speaking, another thing is the coladas, I'm going for the map.. (Enrique)
