Volcanic activity in Canary Islands 2019

[Perrypower1]

Thank you for keeping this going Tamara while Jand is away

[TamaraEnLaPlaya]

You're welcome! I seem to remember we had one on Fuerte last time I was covering as well - I certainly remember posting the info about the questionnaire!
Out of interest, did anyone else experience this tremor, and if so, what part of the island were you in?

[TamaraEnLaPlaya]

Well! It is Canarian Day so only right that there should be lots going on    21 so far!! None over our way though. A big swarm near to Adeje on SW Tenerife.

You are doing a great job while Jand is away Tamara. Much appreciated 🙂🙂

Thank you Tamara for updating the activity whilst I have been away the activity has still been on going over the last couple of weeks.

"Deep earthquakes in the coastal area of the valley of güímar, and follow the activity in the central area of Tenerife, Canary Islands we have had two earthquakes of magnitude 1.5 and 1.9 in the area of south coast of the south Valley of güímar at 28-29 km depth respectively and several more without locating, waiting for data to solve this puzzle by fascicles. The first of them has been right under the volcano of güímar, if I do not fail memory, a cone of almost 400 meters of lava and Stony waste matter separated from metals during the smelting or refining of ore at the beginning of the valley and near the coast and the other in the sea, also very Close to another underwater cone.

On The 2TH THERE ARE 9 EARTHQUAKES AND THE DAY 3 there is a microsismo and when they check today's sure they locate some more among those I have marked that correspond to the activity of earthquakes and microdisks in the caldera area , in the ongoing swarm in the area where the fonolítica chamber of fonolítica has resulted in the white mountain eruption about 2000 years ago.

But what does this activity mean in that area?, it's not easy to explain, but I'll start by saying that everyone has sold us an eruption like the last ones, the one from the chinyero, seven sources, fasnia, etc.. that are bluestones and quiet , but if we talk about a white mountain eruption, the thing changes and a lot. I do not want to be alarmist or augur, I only expose what would happen if we had an eruption with these white mountain osiers, the result may not like it, it would be a violent and explosive eruption very similar to the one that had in vesuvius in pompeii nothing less, That would affect almost all or the whole island to make us an idea. Better not pass, although i have seen it has already passed several times, better be prepared. I leave you an interesting article I found.

Many Canaries wonder and ask me how is their volcanic island?. Say most are huge, in the case of Tenerife, it is colossal, being the third largest volcano on the planet and capable of many things, it is very powerful therefore and It must be very well guarded, the more better since it is active, whether we like it or not.

"El Teide, the only area where there could be an eruption similar to Pompeii "


A Plinian eruption, highly explosive as when the Vesuvius volcano destroyed Pompeii and Herculaneum, could only occur today in the Canary Islands in the central area of ​​Tenerife, from an evolved magma chamber and residual under the Teide.

This is indicated in an interview with Efe Julio de la Nuez, full professor of the Department of Edaphology and Geology at the University of La Laguna, and who has given a lecture on "Explosive volcanism in the Canary Islands: Pliny and Hydromagmatic eruptions" in III Course of Geological Heritage of the Museum of Nature and Man of Tenerife.

Julio de la Nuez explains that at certain times in the Canary Islands there have been highly explosive and dangerous eruptions, such as the Plinian eruptions, which owe their name to the Roman historian Pliny, who witnessed the eruption of Vesuvius that destroyed Pompeii and Herculaneum.

In the Canary Islands the only place where an eruption of this type could occur is in the central area of ​​Tenerife, in the area of ​​the Cañadas del Teide and its surroundings, because there is an evolved and residual magmatic chamber.

The geologist details that the most common basaltic melts come from deep layers, dozens of kilometers or more in the mantle, and usually reach the surface quickly and produce a rash with little time for that molten material to evolve.

But it can be, and this has happened in Tenerife and Gran Canaria millions of years ago, that these melts are paralyzed, remain in a camera or intermediate place at shallow depths -5 or 10 kilometers- for a long time and therefore evolve, that is, they change their composition to a different one: more viscous and with a higher content of gases that can generate highly explosive eruptions.

This is due to the fact that the basaltic melt, while cooling, loses part of its minerals, which are separated and change their composition to one with a higher content of silicas (more viscous) and at the same time accumulate more gases .

All this new composition does not have the previous properties "calmer" and over several thousand years it evolves to generate highly explosive eruptions.

The last eruptive process of this type occurred about 2,000 years ago and originated Montaña Blanca, in the vicinity of Mount Teide, details Julio de la Nuez, who specifies that a Plinian eruption like that of Vesuvius that destroyed Pompeii and that of Saint Helens volcano in the United States United could affect the entire island.

In Tenerife there have been highly explosive eruptions more than 200,000 years ago, in full boiling of the magma chamber under the caldera of Las Cañadas, and some devastated the island almost in its entirety.

A testimony of these processes are the white layers - produced by the fall of pumice stone - that came to cover the whole island and that are detected in areas such as Santa Cruz de Tenerife and Bajamar, in La Laguna.

"The good thing is that eruptions of this type are very spaced in time and are not usually long-lasting.In the case of Saint Helens in Washington, in 1980, it lasted only a few days." It was violent and rapid since in a matter of minutes a huge explosion that devastated several kilometers around the volcano, "explains the researcher.

In this type of eruptions there are also precursor signals that alert of the process, because the material of the magmatic chamber has to open step to 5 or 7 kilometers of depth and being viscous, it produces a lot of seismicity.

In the case of hydromagmatic eruptions, they are also highly explosive and can occur at any time if the process occurs near the coast and in the proper conditions for the magma to mix with seawater or groundwater.

This could have happened in the submarine eruption registered a year ago in El Hierro waters if it had occurred closer to the ground and at a lower depth.

In the Canaries there have been hydromagmatic eruptions in the caldera of Alegranza, Montaña Clara, the white caldera of Lanzarote and the caldereta of Santa Cruz de La Palma, among others.

Precisely the palm tree capital is located right in the middle of the caldera caused by that hydromagmatic eruption recorded thousands of years ago.

An eruption of this type occurs when seawater or groundwater enters the pipe of the magma and turns into steam very quickly, which increases the pressure in the pipe and causes explosions, adds Julio de la Nuez.

The geologist specifies that the first phase of the eruption of the San Juan de La Palma volcano in 1949 had a hydromagmatic nature when it affected an aquifer, which produced anomalous explosions that later led to a quieter, strombolian eruption.

Looks like another swarm has started since midnight already 16 earthquakes have ben listed up to 05:03. .
