Volcanic activity in Canary Islands 2021

[TamaraEnLaPlaya]

Q re the ash.
Do you know what the composition of the ash is? Is it the equivalent of ground up solidified lava? (picon molida)
I've seen it said that it's good for growing crops in/on.

Do you know what's happening here Jand?

Edit - sorry, don't know why it's not showing the pic I was quoting. It's the one with the long yellow hose/pipe whatever!

The answer is :

Stratigraphic cut of the volcano ash for its observation and correlation with volcanic activity.

I wish I was that clever .  

If I see anything though I will let you know.

ASHENS AND PYROCLASTES:

It has been quite active and has thrown ash the last 24 hours, with many volcanic bombs or ballistic pyroclasts which are basically large pieces of stone that come out in explosions, many times of cast or semi-founded material rolling Down the hill from the volcano. In the post I have posted a photo of a cut of the fallen ashes, where you can see how it has changed, both in color, size and texture, indicating the different stages of the eruption. The IGME videos are just spectacular and show us this phenomenon clearly. He has a lot less activity in the last few hours.

In addition the IGME shows us closely the output of the gases and an impressive video of the Graben or dusk lined up with all the fisures of the cone derived from the opening of the eruptive dique and by which the magmatic material moves until out po r the eruption point.

CONCLUSION:

Released seismic energy accumulated follows the trend to decline with 20 MWh today, low and horizontal tendency, which says it will calm down. But don't trust them, I end with my eyes on the deep activity, and keep calm.
Today we passed the 10-day pattern and waiting to see if it passes December 10-12 without reactivating, that is to pass the 14-day pattern, without a deep seismicity of 4.5+ (even 5+). At that point I'm starting to think I might stop for a while, before not. More than 2 weeks, today, no one knows... message I've been repeating since day one.

But at the moment I don't trust and maintain that no one knows what this eruption will last, but at least the indicators are clear, it's calming down, although it still has quite a bit of inertia. It serves as a sample of what he keeps throwing: A lot of encouragement. Greetings. (Enrique)

PD NOTICE: "Lately many people enter to invent this space, better known as "Trolls", with insults and disqualifications to my work or other people in all rules, so I ask for a little indulgence, this is not easy and there is gen I know that everything is worth it. It's not like that, this is not like that. Statistics is that I have 15 users blocked in the last 3 days, that's many, a total of about 35 throughout the eruption. I ask these blocked people not to waste my time anymore, but they like space, just don't go into the f***ery and disturb with their disrespect and moral ethics at the end to all the people reading this space. I accept constructive criticism, questions and debates, but other things I don't. Greetings and good night. "

09/12/2021 16:00h Canary Islands. - SMALL SEMO-VOLCANIC HANG IN ADEJE, TENERIFE. - CONTINUATION OF AN ACTIVITY THAT STARTED 5 YEARS AGO. -
Not everything was going to be the Palma, they have to think that there are other volcanic islands, and although these days it is almost a monograph of the Palma, things happen. This is important enough to comment on. In the last few days, 13 small earthquakes and microsisms between magnitude 0.2 and 1.6 have been located in the Adeje area, at depths between 5 and 9 km, mostly between 6 and 8 km.

This would be nothing but an anecdote except because it is the continuation of something that started 5 years ago and we have already had stronger swamps in that area, in October 2016, November 2017, November 2018, July 2019, December 2020 and more..

As far as you can see this time is that a seismic alignment has been formed in the direction of NNE-SSW from the Orotava valley towards the port of Christians, passing through the central building Teide -Pico Viejo and the Caldera, indicating that to lgo is moving down there. Something somehow normal in volcanic islands, that is, but something to watch out for.

In fact, this reason was one of the first posts in this space after 10 years on AVCAN... to be said soon. Post number 009 November 2017 and a few more.

There is a saying that "when you see your neighbor's beard peel, put yours to soak." Tenerife, as Palma is already being touched by statistics, let's hope it still takes many years to make an eruption, because it will eruption. What we don't know exactly when and with each passing year the probability increases. (Enrique)

09/12/2021 - 22:00h Canary Islands. - ERUPTION OF LA PALMA ISLAND. - DAY 82. - THE IMAGES OF COLLADA 22. - THE REAL AND THE ONE THAT RESULTS IN THE INFRARED. - In the satellite photo of the lava coladas taken by the Sentinel you can appreciate very well the active coladas with some red in the true color where the bands 2,3 and 4. are combined But it's impressive how it looks with a yellow red color if the infrared bands are included, which are typical of hot objects and which are 11 and 12. Another way of looking at an eruption. Thanks to Isaac for helping me prepare this information.

Tremor and GPS DEFORMATION

As far as the volcano, the tremor has stabilized and has risen a little bit finding around 21-22 units of RSAM and while deformations continue, with a slight downward trend in LP03, which marks a slight pressure drop.

IN CHANTO A LAS COLADAS, La colada 22A continues to fall down the cliff, although it is not very eager to see it, although the supply of lava is good as seen in the thermal video and in the satellite photos. It's had minor showers in the south area.

SCREAMS AND PYROCLAST CONE

The presence of large cracks in the cone of pyroclosts is not new, the intrusion of the dique produces them, once it is opened, no longer closes, or does not do it at all, because there is material that cools in the dique itself and prevents it from closing the everything. So as the pressure goes down, the lava goes down in some areas, and there is a gap where the material on the sides is falling into these holes that remain in the same and sinks occur in the central areas or record, and of course the aper round of more cracks in the cone itself.

RELEASED SISMICITY AND SESMIC ENERGY

Seismic energy continues to decline, the system continues to deactivate and tend to horizontal, in fact today has marked a new, very minimal, with values of the days before eruption. from just 3 MWh, a total of 130 Mwh in the last week. In addition to lowering the tremor, Events of lower magnitude are being located in the environment of magnitude 2.

ENVIRONMENTAL GASES AND VOLCAN EMITIONS:

I have not found new data of SO2, but instead in the environment, the stations of the Llanos and Puntagorda mark values that are not good for health, with the smell of rotten eggs and Azufre more of the reason and which of course is not healthy, by I'm going to be a I ask you to look at it before going out or opening the windows. Only in the hours I drop below 50 can you already consider it not bad.

CONclusion: Hoping this is over, but I'm not going to say it's going to end anytime soon, not that the dog will risk it again, but the truth is that for now it's calming down, and much more than previous times.

I hope this eruption ends already, but I don't trust a volcano hair, I see it with a very good and constant lava contribution (tremor) that doesn't let me make a forecast of finishing correctly.

However I share that the forecast of seismic energy released now has a lot of error and marks the end in just a couple of days to zero, I'm sorry but this fact I can't believe it. And more knowing that there are many earthquakes less than 2 that are not localized and seeing the stability of the tremor. Cheer up Palmeros. We'll see what he does. (Enrique)
