IGN have still not updated any earthquakes for La Palma or El Hierro since the 15th February whether this is a blackout by them or there have genuinely not been one earthquake on these islands since the 15th February is the question I think many people will be asking .

Latest update courtesy of Enrique.

''earthquakes in the area of the volcano in the middle, North of the island and a microsismo in the caldera of Tenerife, Canary Islands, Spain.- 21/02/2018-today, no one has located, but the events are staying In the inkwell, without locating, as you can see in the little thing that is seen in the signs of with some faint but noticeable signals at 01:40, 01:47, 04:29, 08:02, 08:03, 10:44 and 17:35 H. See if they can locate any when they check tomorrow.

To point out also that what happened a few days ago on the island of LA Palma is very rare for earthquakes to stop so suddenly, rather it seems another thing, that in the ign they have not followed located or have not been wanted or not He has been able to locate more for reasons I do not know, because one has been registered, which is leaving an information gap that does not reassure anyone.

Yesterday, a faraway event of magnitude 2,5 and deep 42 km north of Tenerife, which will take more off the island when they check and will be less deep. It has then been located microsismo 0,7 to a depth of 21,2 kilometers very close to mountain shredded in the interior of the teide caldera, last yesterday, an earthquake of 1,7 to 16,6 km Depth at mid-morning in the sea between Tenerife and Gran Canaria about 6 km to the wnw of the volcano in the middle. That same night, but antesdeayer, two more earthquakes, one almost located under the volcano in the middle and the other further south. (Enrique).''

Volcanes y Ciencia Hoy - Volcanoes and Science Today. Quieren una muestra de lo que digo, que no es cosa mía solamente. A ver que opinan, Les presento el espectrograma del sensor de la Palma y miren lo que hay a las 14:33h. ¿Que es esto de hace un par de días? un terremoto claro como una casa, ( de mas de magnitud 2 viendo lo que localizaron en el enjambre), un evento sísmico desconocido o incluso un deslizamiento muy cerca de la estación.

Por adivinar... dirán deslizamiento según la fuente oficial por aquello de llevar la contraria, pero con la señal tan pequeña y amortiguada, es sismo para el resto del mundo. esto pasa por informar mal o sin dar detalles para el gran publico. (Enrique).

EDITADO: Esto es lo que dicen en el facebook de Multiteide:
"Es algo muy local (sólo se ve en 2 estaciones). Aparentemente puede ser una pequeña caída de rocas en la ladera o algo de origen antrópico".

To see what you think, I give you the of the palm sensor and look at what's at 14:33 What's this about a couple of days ago? A Clear earthquake like a house, (more than magnitude 2 seeing what they tracked in the swarm), an unknown seismic event or even a slide very close to the station.

To guess... they will say slip according to the official source for the contrary, but with the signal so small and muffled, it is an earthquake for the rest of the world. This is about reporting bad or not giving details for the great public. (Enrique).

Edited: this is what they say on's Facebook:
" it is very local (ONLY 2 seasons). Apparently it can be a small drop of rocks on the hillside or something of anthropic origin ".

The following has been translated.

We can not say that we are facing the prelude to a volcanic eruption on La Palma"
Stavros Meletidis, geologist from the National Geographic Institute, analyzes the reactivation of the seismic activity that occurred on the island of La Palma

DAVID SANZ 2/18/2018 · UPDATED 01:15



Stavros Meletidis, geologist of the IGN. | GIVES
Stavros Meletidis (Thessaloniki, Greece, 1969) is a doctor in Geology and is in charge of the interpretation of seismology, geodesy and geochemistry data of the Volcanic Surveillance Network of the National Geographic Institute (IGN) in the Canary Islands. Specialized in volcanology and geothermal, this scientist has participated in various European projects related to these fields of research. In the Canaries he works since 2007 and intervened, in 2011, in the volcanic reactivation of El Hierro. La Palma now focuses its attention, with the rebound of seismic activity that has occurred in the Cumbre Vieja Volcano.

- What is Cumbre Vieja?
"Cumbre Vieja is the continuation of volcanic activity in the area where La Palma has grown, which has gone from a phase of generating central volcanoes, such as Taburiente or Bejenado, by giving monogenetic eruptions south of them. Apparently there was a migration of the material that found a faster path upwards and that is why the eruptions we see, most, if not all, are basaltic, where the magma, according to what has been studied, rises rapidly ( in geological terms), and it reaches the surface. The rapid rise determines the type of eruption, its products and its explosive dynamics (we have basalts instead of other materials, such as phonolites, which we have in Tenerife, which would be much more explosive and dangerous) "

- Are not we then faced with a dangerous volcano?
"The danger has to do with the preparation we have. The Chinyero or the Teneguía, at the time, were a spectacle, but if today we had a similar eruption we would have enough problems in infrastructures, communications, etc. Cumbre Vieja is not a central volcano, Teide type, that can generate an eruption with pyroclastic flows and all that we see in the movies. But yes, always depending on the point of emission of the material - because Cumbre Vieja has a central part and on both sides a steep slope - the lava can reach the coast very fast. Something that has already been seen in previous eruptions. Much of the coasts are nothing more than land that has been reclaimed from the sea with eruptions (lava platforms). The danger depends a lot on what we have in between. "

- Cumbre Vieja is like a volcanic building where volcanoes have been produced inside, such as Teneguía or San Antonio?
"We could compare it with the rifts (dorsal) in Tenerife. Prolonged areas, where the material coming from below finds a part that is much weaker and fractured due to previous intrusions and costs less to climb. That is why it is the preference of the magma to rise in that area. It is much more difficult to do it under the Caldera de Taburiente or in the north of La Palma. It is an active area for the last 100,000 years and all historical eruptions are concentrated in the Cumbre Vieja building. "

- Is it the most active volcano in the Canary Islands?
"Yes, for the statistics. In the historical epoch, which for the Canary Islands are the last five centuries, we have had more eruptions than on any other island. Maybe if we go to a wider era, it's not like that, but we're interested in the volcanic effect on humans. "

- What interpretation do you make of these seismic swarms that have happened on La Palma?
"These have always existed. I'm not saying that we should minimize it, but any movement of magma under the Island will generate those records. We must bear in mind that before we did not have the instrumentation that we have today to locate them. I'm talking about the time of the San Juan volcano of 1949 or the Teneguía, which they noticed, and quite late, by the American base of Puerto Naos. From what has been studied on La Palma, it is seen that the magma rises and makes two clear stops before reaching the surface. Then, perhaps, we are still in the first of these two stops, which may take several months, years and even decades. We can not say that this is the prelude to an eruption.

As an example they are The Bells of Jedey, that is phonolitic material, that has not given an eruption and had to arrive the one of Jedey to bring them to the surface.

Below the islands there are small pockets of magmatic material, which may or may not reach the surface. It has been seen in El Hierro or in the Teneguía, which is the mechanism of functioning: the material goes up and there comes a time that either because it does not have enough energy or because there is not so much material to break what is above, Stagnates and starts to cool. It is not a thing that we directly have to think that there is an eruption, although it is not impossible.

For now, because of what we see of the surveillance network that we have, we only see the seismic network records, there is no deformation, because we are talking about movements of a lot of depth and of very low volume.

It is clear that the nature of the phenomenon is volcanic, but to say that something is rising we need more indications, such as the deformation of the terrain and the possible emission of volcanic gases.

The magma is there and is entering into discontinuities, small bills and breaks the material a bit. It may be that 60 years ago the same thing happened, or 30, but we have not had any chance of registering it. "

More news
Cumbre Vieja lives the most important registered seismic swarm
- Even if the tremors are not felt by the population, will it be normal for La Palma to live with this seismic activity?
"I think so. The eruption of Chinyero had earthquakes years ago. In almost all the islands, with or without eruption, it has happened. Because in El Hierro, in 1793, there was a lot of seismicity but no eruption has been seen on land. They are phases of normal life, of the evolution of the islands, and it is logical that every x time, which we can not determine, however much we like the statistics, part of this magma will try to climb because it has reached a maximum volume that you need to do it or because you have found a fracture where you can climb. Then, the swarms will always exist. There are moments that we can feel them and others that we can not. It is the nature law" .

- The seismic activity recorded in La Palma has been attributed by the Pevolca scientists to processes of magmatic intrusion. What are they?
"When we talk about magmatic intrusion, imagine that we have a street, where you install a water pipe underneath, it breaks, and the water starts to push up and lift the asphalt. An intrusion is when volumes of magma start their journey up. When I say up I mean that they go from 50 kilometers to 25 -15 km or less.

When that trip occurs, the magma begins to enter the pre-existing rock and finally the crust, which is the most rigid part of the Earth, and this, instead of changing its shape to fit there, breaks. That generates small fractures, which the magma takes advantage of for its ascent, perhaps from different points, and the seismicity is generated. When talking about intrusion, it is not a massive intrusion. Do not think that the island will be built. It may stop tomorrow, may it continue again or that after x months or years there may be a rash or not. "

- When the name of Cumbre Vieja is heard, the hypothesis of the great tsunami comes to mind. What do you think of that interpretation?

"All this began because in 1949, during the eruption of the San Juan Volcano, a very superficial fracture was seen, which was nothing more than the effect of the magmatic material, which, in the form of a dike, passed from one emission point to another. Because in 1949 there were three different emission points, which came to work simultaneously. If we relate this superficial fracture to the fact that the Cumbre Vieja part is a volcanic phase different from what the central part of the Island has generated, with this they have made a model. It is clear that in the oceanic islands there are landslides, but they are not generated with a seismicity of this style, nor with an eruption.

We are talking about a much bigger, wider phenomenon that has to affect the entire island. In addition, in the geological part, to cut a few kilometers of rock on the island, you would need multiple intrusions of material, which at the same time would destabilize all La Palma. And in the physical part, we must take into account the volume of material that is involved in an eruption and consequently we would speak more of landslides than of a landslide. These geological phenomena do not occur very frequently, and the previous landslide on the island occurred almost 600,000 years ago.

There are researchers who have disassembled it. I do not think anyone right now holds that the island can be split in two, although it will always be heard. In El Hierro, when we were working there, they said that it was also going to split in two. We must bear in mind that an island is pure rock, we speak of five kilometers of rock and it is not so easy to split it ".

- Now that you name El Hierro, could it have any similarity with what La Palma is living now?

"Yes, it might seem. The two islands belong to the same Archipelago with the same style of volcanism. It can be something very similar, I mean in its operation, but not in the times. If we have an injection of material at a depth of 25 kilometers and there is sufficient volume, this material will try to climb, through pre-existing fractures or breaking the rock. What we do not know is the rhythm or the guidelines that will follow, if there is enough magma to continue climbing. In El Hierro, what we had was that at first it was seen that the seismicity was less deep, which is an advantage because it does not have to travel as much.

ELEMENTS OF THE VOLCANIC MONITORING NETWORK OF THE TERRITORY OF PALMERO
The National Geographic Institute is the body responsible for volcanic surveillance. After the seismic swarms of October 2017, it reinforced the insular control network with the installation of three new seismographs. In total, thirteen seismic stations take the pulsations of the palm territory. To this are added four other geochemical stations and the same GPS figure. To which we must add the Involcan network and the geochemical research program that it develops.

'' earthquake from 4.1 to ne of the island of LA Palma.- this morning there was an earthquake that has been located by the ign to ne of the island of LA Palma at a depth of 18.8 km It tells us as we said yesterday regional tensions to judge with the last 6 earthquakes that are all aligned in an address nw - se. It could have been meaning in some populations weak, especially on the island of LA Palma.

It has clearly been marked in all the seismographs, notandose the s and p. In Maci, there are also small moves that they may locate when they check the 01:20 h or two smaller to 03:25 and 03:31 H''. (Enrique).

''067 swarm and seismicity on deferred on the island of Tenerife, Canary Islands, Spain.- IGN has located several new earthquakes inside the island of Tenerife in the past days in what appears to be the result of a computer malfunction, That they haven't called anywhere as usual.

Communiqué from ign to gevolcan:

"once we cured the problem we had in the system when we were going to upload computer earthquakes to our public web of ign, these have been the earthquakes in these last 15 days in the Canary Islands"

From Gevolcan we thank itahiza ign for this deference to us.

P D. To say that the Instituto Geográfico Nacional de España y CNIG (IGN) has located many more seismic events in Tenerife than those that have located involcan.

These have been all the earthquakes located in the last 15 days in the Canary Islands, from the past March 4 to today 19 March 2018.

In Tenerife, a total of 23 seismic events have been located between 0.8 and 2.0 mblg and with depths between 3 and 22 km. Part of an earthquake in the sea, far away, to the nw of Tenerife with a magnitude of 2.1 mblg to 49 km. In depth.

In Iron, a total of 4 earthquakes have been located between 1.7 and 3.5 mblg to depths between 11 and 38 km.

Update courtesy of Enrique regarding the latest activity.

Translated.

''Earthquakes in Tenerife and surroundings and also some notable for the iron and surroundings, Canary Islands, Spain.- today we have started the day with a wiggle of magnitude 1.6 this morning without depth off the coast of arico, about 15 Miles of the coast. After Mid-morning there has been a microsismo located by the ign in the east area of teide about 4 km from the summit and a depth of 6 km. Past noon we have had one more remarkable of magnitude 2.6 about 2-3 km off the coast of arico at a depth of 22 km.

Today, 29 March 2018
Es2018dmepb 29/03/2018 03:57:42 04:57:42 28.0143-16.3735 0.00 1.6 Mblg Atlantic-Canary Islands

Remarkable the seismic movement these days, without being anything to worry about, but indicates that the system is alive and well, with an almost n-s alignment of more than 15 earthquakes in the boiler in the last two weeks since Zone of mouth of tauce to the nose of teide on the sw flank of Pico Viejo. To say that some events are not localized in principle until after a few days, which we say:

In the ign earthquake viewer you can appreciate the epicenters of the seismicity of the last 15 days, with several events in the caldera area and around the central teide-Picoviejo building. (Enrique)''

This question was asked by someone.

''Podría existir relación entre sismos a medio camino entre el volcán de Enmedio y el Teíde? Después del 2,6 la cosa se animó.''

''Could there be a relationship between earthquakes halfway between the volcano in the middle and the teide? After 2,6, the thing was encouraged.''

The swarm did start after the 2.6 earthquake maybe there is a connection ??

I am no expert by any means but looking at this graph for today I think there may be many more earthquakes on Tenerife.

Perhaps someone with more experience could comment .
