Latest statement from Involcan.

Translated

:After the passing of the night and the absence of earthquakes, may be finished the episode of seismic swarm registered on the day of yesterday on the island of Tenerife. Said seismic swarm responds to the common activity of an active volcano, but in the case of the island of Tenerife are a rarity, which obliges her follow-up.
Let us remember that a seismic swarm is the occurrence of a set of seismic events in a specific area over a period of relatively short time without any associated a main quake.
The rest of analysis of data from the involcan, at this time the report is as follows:
GPS stations: is not deformations attributable to this episode of abnormal seismic activity. This absence of deformation may be due to the fact that there is not an injection of magma in the basement, which would make this episode of seismic activity could relate to the hydrothermal system of the volcano, and not with a magmatic intrusion. We continue analyzing and observing the signs that you receive during the day today.
Gases: two teams of involcan are already in the area of the swarm to carry out a campaign of estimation of diffuse emission (not visible) of carbon dioxide. In this regard it should be noted that the involcan has registered in 2015, a relative increase in the emission of Co2 as compared to previous years in the North-West Ridge, without these values will come to be extremely high.
Despite the fact that this episode can be classed as abnormal, should not be a source of social alarm, because in any case there is a sequence of "Action-reaction". a large number of seismic swarm appear and disappear without lead to another type of activity Yes, but they are a clear demonstration of the dynamics of an active system like the Tenerife.
We will continue producing reports during the day today.

:Two earthquakes located in Canary Islands and follows the microsismicidad in Tenerife, Canary Islands.- in what's going of late, in the last few hours we had an earthquake of 2.6 located south of the island of Tenerife at only 2 Km deep which has been preceded by two events at 13:12 pm that have not been located by the ign and which can be seen perfectly in the seismogram of Maci.
The earthquake of 2.6, also in the spectrogram of Maci, I have followed two pulses of earthquakes with 3-5 in the first between 14:04 and 14:06 h UTC and the second with nearly a dozen signs something else Long between 14:32 and 14:37 h UTC.

Latest report from Involcan they are saying there could have been more than 400 earthquakes.

Translated.

:Report on the seismic swarm of October 02
Below is a breakdown of the most significant findings of the report prepared by Dr. Luca D ' Auria, head of the functional unit of volcanic seismology institute of the Canary Islands (volcanológico involcan), on the earthquake swarm of Sunday, 2 October 2016 registered in the island of Tenerife for the national seismic network after the Exhaustive analysis of seismic signals.
1. Characteristics, the distributions between events and of magnitude reflect clearly that the events of the swarm of 2 October 2016 can be classified as reasonably earthquake-volcanic events of long period.
2. The estimated number of seismic events reported in the national seismic catalogue could be underestimated. An approximate calculation based on the spectrogram reflects that the number of seismic events could have been more than 400 events.
3. After 17:58 hours the individual seismic events merge into a continuous train of seismic events that lasts until at least 19:35 hours.
4. The Distribution Hipocentral (distribution of the spotlight or depths of seismic events) is likely to be a "Artifact" due to the geometry of the low seismic network of the ign and to the small size of the events in assessing this type of Processes. Seismic Events are probably much more grouped together in a small volume.
5. the depths of seismic events should be revised, given that they could be significantly more superficial that the reported by the ign.
6. The Wraith shows similarities with the wraith of the events of a long period and tremor observed in Tenerife sismovolcánico during the crisis of 2004. Plus share characteristics observed in other active volcanoes in the world.
Once again, we must insist on the absence of a sequence of "Action-reaction" for this kind of phenomena, as well as the need not to fall into unfounded alarms. The emergence of these phenomena can be as sharp as his disappearance, although this is an activity of any other kind. The Involcan will also make the relevant investigations for further communication on the basis of the signals to go searching.

His comments on them . Translated

:The sounds of today October 4, 2016 captured by IGN MACI station between 7 and 9 GMT, accelerated 200 times. Two hours turned into something more than 2:45.
My interpretation is that it is events long period, they sound as if a child were trying for the first time sounding a tuba or trombone. Or an old canary fisherman, announcing his bucio (conch), there fresh fish ... In short, there are fluids either volcanic hydrothermal nature or nature or both together, going outside for cracks or ducts in the ground.:

:This morning on the news the canary have said that after the meeting that they have had to study confirms that it is of volcanic origin and without risk to the population:

IMO the comment below on the Involcan facebook page and from another Spanish person has some sensible questions especially when people live on a Volcanic Island and have no idea what to do if there ever was an eruption.

Translated.


When " we are not trained in where we live " that are volcanic islands, which we call the volcanoes " mountains ", we don't know what they're doing the volcanoes, with whom we live every day, " and they only sell sun and beach "and parties", they expect us to know the simple people. If we remember Santa Barbara when it thunders, what else do we want to ask. You have to educate the population in the schools and on all sides, and to know what are the measures of protection and that we need to do when a volcano eruption, let us learn from Hawaii, Japan, etc. Since children know what they have to do and living out of tourism of the volcanoes. So it would be better, and put to each person and agency in its place. And once you have union of all the agencies, no desire to "Thunder" by some. Would like to congratulate the whole team of involcan all over this great work he is doing for many years, and to inform the population in this new crisis on the island of Tenerife.

There is a discussion on the internet as with the activity in El Hierro years ago that information is being withheld in relation to the activity on Tenerife.

As an example on the IGN website 4 days of activity on the 3 4 5 6 of October was not shown .

If you look on this link and click on the 15 days tab on the right hand side you can see these dates are missing for activity in Tenerife.:

Example Comments being discussed at the moment:

Por fin se habla claramente del catalogo B de los sismos o de la ocultacion de datos, menos mal que ya le han medio puesto el cascabel al gato y mas que deberian de decir, pero el paso va por buen camino.
Si no mirar las graficas de la ultima crisis en tenerife que derepente el ign ha hecho casi inexistentes o casi inapreciables casi desapareciendo de los mapas graficos.

He finally speaks clearly of the catalogue b of earthquakes or the concealment of facts, it's a good thing I already have the middle post bell the cat and more than they should say, but the pass is going in the right direction.
If you don't look at the charts of the latest crisis in Tenerife that suddenly the ign has done almost non-existent or almost priceless almost disappearing from the maps graphics.

Vivimos en un archipielago de origen "VOLCANICO", cualquiera con toda esta ocultacion diria que vivimos en el area 51, turismo, turismo vamos a sacrificar a la poblacion por el turismo que por lo visto no tiene claro que somos islas volcanicas

We live in an archipelago of volcanic origin " ", anyone with all this concealment would say that we live in the area 51, Tourism, tourism are we going to sacrifice the people by the tourism, which apparently has no clear that we are volcanic islands



Artículo de obligada lectura, una de las cosas que dicen.- El denominado enjambre sísmico reciente en Canarias, al que se puede acceder en la Web del IGN registraba el pasado domingo 2 de octubre 96 movimientos sísmicos en sólo 4 horas, pero la ausencia de ninguna nota explicativa en su web sobre esta actividad sísmica anómala con fines de informar y educar a los ciudadanos sobre este proceso representaba un claro caldo de cultivo para fomentar una alarma social, dado que los seguidores de esta web tienen conocimiento que ese nivel de actividad sísmica en Tenerife en sólo 4 horas no era normal.

:Harri Geiger and Abigail Barker, both of the Department of Earth Sciences of the University of Uppsala , in Sweden, expressed Saturday that if in the Canary Islands a volcanic eruption occurs, its dimensions would be similar to that of Eyjafjallajökull in Iceland in 2010. Between other effects, there was an air traffic chaos hit 5,000 flights in Europe.

This data has been released to coincide with a series of earthquakes that have occurred in Tenerife in recent days and have drawn the attention of geologists canaries.

In a study just published this week with the cross earthquakes data Mount Volcano Carmerún, which has had ABC access, both scientists recommend technicians who are studying the phenomena that have occurred in recent days in Tenerife analyze other parameters . Reason: There is a complex system of magma plumbing and monitoring is key strategies for risk mitigation and early warning.

"We were able to reconstruct deep storage reservoirs of magma at the bottom of the crust and magma chambers shallow in the upper crust. These shallow pockets seem to migrate in times of volcanic inactivity and can play a crucial role in the priming erupting volcano , "says Harri Geiger.

The results also suggest that " there migrations to shallower waters where evolve and increase its explosive potential ." Therefore, "a longer time between eruptions increases the likelihood that the next eruption being more explosive in style, similar to the eruption of Eyjafjallajökull in Iceland in 2010".

Explained that "the problem of volcanic surveillance is that it is easy for signs, but it's hard to know what signals are significant ". Therefore, recommends: "Our message to the monitoring equipment is that it should focus on the seismic signals of migration of magma from about 20 kilometers deep , because such signals are very likely to precede eruptions" says Abigail Barker, researcher at the Department of Earth Sciences in Uppsala .

"The emergence of pockets of magma shallow probably plays an important role in the styles Control eruptive during eruptions and therefore should be considered routinely in efforts to mitigate risks . We believe that these findings have implications for other volcanoes related in Iceland, Cape Verde islands and Canary "says Harri Geiger.

And geologists at the University of Uppsala have traced the movement of magma beneath the volcano Mount in Cameroon to assist the monitoring of future volcanic eruptions . The choice of Cameroon is not accidental. Is the largest and most dangerous of Africa , and its eruptions pose a threat to almost half a million people who live around them.

A team of researchers from the University of Uppsala was proposed unravel supply system magma lies beneath the volcano in order to gather information about the inner workings of the volcano "and to help improve strategies for risk mitigation and early warning" , says Geiger.

The findings indicate a complex magma plumbing system beneath the volcano Cameroon referred by analyzing the two most recent eruptions in 1999 and 2000.
