Volcanic activity in Canary Islands 2020

[jand]

On the link below click on the right hand side 15 Dias Wow a lot of earthquakes still and quite a few surrounding the islands over 3.0 magnitude.

Welcome back jand 😁😁

Thank you Tamara for the posts hope you are well and everyone else.

As having to self isolate being in the most vulnerable group its been and still is a difficult time not just for us but I am sure everyone else.

The activity is ongoing just noticed these earthquakes showing on EMSC today.

"SYISMIC ENJAMBERS AT 120º IN THE CALDERIFE CALDERIFE AREA AND ARIAS, CANARIAS, SPAIN.- 17/05/2020.-These last few days we continue with enough activity, but the novelty lies in what not it looks so easily, the shape of seismicity. It clearly indicates a concentration zone of efforts around the caldera of the Cañadas del Teide, in Tenerife, specifically over the area of the caldera of Ucanca and the south and southwest slope of Pico Viejo.

This is seen by the formation of a mercedes star configuration at 120º of the earthquakes that indicate that something pushes from below, (the bag or magma camera), either by regional efforts that tighten it (the case that we occupies) and it is not noticed in GPS or by a magmatic intrusion that pushes it (in this case GPS sing it) when terrain deformation occurs.

This morning you see two small seismic swarms, the first around 02:56 am in the boiler with 3 located Events and one a few minutes later around 03:20 with 2 located Events.

Of these 5 localized, 4 are in the Caldera area and one in the area of the swarm of Vilaflor, the two areas with magma bodies or magma chambers, which respond to efforts with small signs of sequential depressurization ( like a coffee maker or steam machine). The important thing about this is that they are there. A change of conditions (magmatic intrusion, nearby strong Earthquake, slide), could lead to them becoming unstable and end up in a rash. Fortunately, not at the moment.

Also as a relevant fact, a couple of earthquakes have been noticed slightly on the island of Tenerife very weak, one of the area of the deep Enmedian volcano and the other in the Granadilla de Abona area, relatively deep also that tell us that the seismic activity and regional efforts are present and seismic follows its tran - tran.

For many to be prepared for a volcanic event is an unassumed overrun and alarmism, an economic waste we go, but when the skinny cows arrive, to skinny dog everything is fleas... there is no economy to resist it and if it gets bravo, there is neither Population that resists it.

In Tenerife, the next eruption by statistic, but it has not arrived, nor will it come in the short term, but of course, the system is not dead, it is there waiting for its moment and the best thing you can do is keep an eye on it and get ready for whatever comes.

Only the previous tremors, before the eruption will be more destructive possibly than the eruption itself, which few people know and that the Canaries have been suffering many centuries with many dead as a result of the collapse of houses by those previous earthquakes in historical eruptions I love you so much The eruptions instead have been much more benign, as far as dead are concerned, well it's true that the last ones have been non-explosive basaltic, we would see what happens in other scenarios..... Happy Sunday. (Enrique)"

EEP SISMICITY IN THE TENERIFE CALDER AREA AND AROUND WITH ACTIVITY IN THE SOUTH DORSAL, CANARIAS, SPAIN.- 19/05/2020.-Many times I have commented on the connection that exists through the bibs of the type of volcanism in Tenerife, but in the south dorsal things are not that simple. In the NE and NW ridge eruptive points are usually monogenetic and also basaltic, while the boiler and surroundings show more evolved magmas points that are not usually basaltic, (some there are)

The southern bib is more complex, it is a mixture of everything and more than southern bib, it would talk about southern bibs, as there are several axes and many volcanoes of all kinds of composition. I'm going to tell you a possible scenario that could fit what we have in Tenerife today.

What I want to highlight today is the presence of deep seismicity just under the phonolithic magmatic chamber of the Teide, more than 15 km deep, which could indicate regional efforts and possible opening of the canal or dam or fissure that leads magma of the mantle to This camera, marked as step 1.- Possible deep magma input into the system (there has to be more earthquakes and stronger to confirm this and GPS notice something)..

es2020jtrgs 18/05/2020 19:24:41 28.2273-16.6878 16 0.8 mbLg E ISORA GUIDE. ITF
es2020jshbj 18/05/2020 01:07:22 28.2234-16.6826 22 1.0 mbLg NW VILAFLOR DE CHASNA. ITF

Step 2.- This magma input, if it occurs in the future (2.-), will cause many more earthquakes or earthquakes in the boiler area, some with magnitudes over 2 e even 3 in the boiler environment when there is a pressurization of the magmatic chamber (under the caldera of Ucanca and south of Pico Viejo). This camera is now in case something pressurized judging by the earthquakes we have between 14 and 10 km and responding to regional efforts.

Step 3.- This step occurred to me if we applied what happened in Hawaii in 2018, which means, the magma would come out the top of the boiler chamber (about 10-12 km) and could migrate south along the south rift or rift or dam that opens, and directs towards the magma chamber of Vilaflower (of unknown composition, but it must be evolved, let's go I don't think it's basaltic) that is somewhat more somer between 10 and 6 km deep with relative ease once this conduit opens, with a moderate seismicity that would give earthquakes of 2-3 and is not disposable until one of 4 and even that whether we get to have something on surface or a phonolithic eruption, aborting or not the next steps.

Step 4.- is logical, involves the pressurization of this Vilaflower chamber with more seismicity and more somer and stronger, between 2-3-4... and a 5 break is not disposable, which allows the material to go out to surface.

Step 5 is the continuation - it is that migration to the surface of the magma, come on, the eruption, but it is not known the emission point that would be located from the area of activity of Vilaflor to the south, following the bib, with possibility opening of emission points (there will be several along a fracture of some km where one of them will quickly become the main to give Guaza mountain things or the Simon loin, and even without ruled out that it reaches further south and that could erupt in the submerged area like it happened in the Iron.

For this deduction I have taken as a reference what happened during the Hawaii eruption of 2018. The bib opened, up to 24 emission points were formed, prioritized point 8 and the first lava that came out, had very similar composition to the eruption of 1955, indicating that it was in a reservoir as is the Vilaflower bag and then the new lava arrived from the top of the Kilauea. The volume was the most striking thing, as it drained an enormous amount of magma from the boiler, collapsing, generating a huge hole, where a water lake has now formed.

We'll see what happens, it's exciting to see how earthquakes respond and are placed according to the South bib, it's all a warning to navigators (Enrique):
