''049 seismicity in Tenerife and el hierro in the last few days, the Canary Islands.- today a microterremoto of magnitude 0.8 has been located in the east area of izaña in fasnia at a depth of 3.6 km.

There are also some signs of small earthquakes not located by the ign in the seismogram of Maci at 02:35 H, 03:02 H, 06;47 h, 10:28 H, 11:42 h and 12:36 H, In addition to noise by wind, waves and anthropic at various times, and hopefully at least we will have some in the next few days. By the way, the Lisa signal from the 05:15 h is a parasite or error in the signal.

In addition to the earthquake review in the iron we had yesterday they have up a very special one, which is finally three of the ones we had yesterday, although in the seismogram you can hardly see anything. By the way, if we also consider the earthquake three days ago, this 4 earthquakes form a perfect Mercedes star with a larger center and the minors around 120º, white and in bottle. The Iron building is subject to efforts that come from the bottom up and responds sismicamente that way.

The reason why this quake is very special is the data that are shown in the phases, because the magnitude it puts in the phases is not the same as it appears in other phases, with two possible data, with what is left A reasonable doubt, it was a 1.7 or a 2.7.

This is what the new 1.7-encoded event file sets as: Es2018bdkbf:
Magnitude Err Nsta Author OrigID
M _ MB 1.7 0.4 IGN 018 bdkbf
(M_mb stands for Mw(mb(V-C)))

(MB _ u stands for mb)
http://www.ign.es/web/resources/sismologia/www/dir_images_terremotos/fases/2018/es2018bdkbf.dat

Instead if we look at the 2.3 located yesterday encoded as es2018bdpcm we have this:

As you stay??? I without any explanation for the moment, I would like someone to explain to me what's going on here to change the way of measuring the magnitude of earthquakes at random and why?. (Enrique)

051 revised earthquake located in icod of wines, Tenerife, Canary Islands.- IGN has up an earthquake of 1.1 a couple days ago in the area of wines at a depth of 5.4 km . This earthquake is not anything, it is the continuation of the seismic activity that has been moving the island over the last 3 months and I will summarise them below with the main lines of effort, which is quite interesting. By the way, these lines intersect in the s-age area in the area of the eruption of or teide noses

OT the Azore Islands have had 300 earthquakes since Monday .

Translated.

''At least 300 earthquakes of medium magnitude were recorded in the Azores Islands on Monday morning. According to the Center for Information and Surveillance Seismovulcanic of the Azores (CIVISA), since 23:47 on Sunday there have been hundreds of seismic values ​​between 1.9 and 3.6 on the Richter scale in the Portuguese archipelago, located in the middle of the Atlantic Ocean.

The Portuguese Institute of the Sea and the Atmosphere (IPMA) warns that there is no indication that the seismic crisis that affects the Atlantic islands diminishes, and that on the contrary more earthquakes, possibly of greater intensity, can be expected in the next hours and days .
Several hundred “microseisms” were recorded on the island of São Miguel, including a “significant” event at 06:18 in the morning, which reached intensity V of the Mercalli seismological scale, reserved for shocks that generate material damage slight, cracks and disturbances in tall objects. Material damage has been recorded, in the form of broken windows and fallen poles, in several islands of the archipelago .
For this reason, the Regional Civil Protection Service of the Azores has asked citizens to remain calm and take measures to protect themselves; The population is asked to avoid the use of matches and lighters due to the high risk of gas leaks, as it is also requested that those who notice significant cracks in their buildings abandon them and inform local firefighters as soon as possible. Likewise, the Azoreans have been asked to avoid the coastal areas of the islands due to the high risk of tsunamis generated by seismic instability.”

''seismic swarm - volcanic ongoing on the island of LA Palma since yesterday, canarias.- Several earthquakes have been located by the IGN WITH 5 yesterday and 6 today around the magnitude 2 and Major, they will probably put more of a smaller scale when they check (we are carnival and volcanoes like parties, do not forget). It must be remembered that the pevolca, it meets if it happens more than 10 a day.

In the ign special report, this is what they put:

" last Saturday day 10, at 23:23 you started a new seismic series located in the southeast of the island of LA Palma. Up to now (day 12 to 11:00 TU) a total of 9 earthquakes have been located, with quantities ranging from 2,2 to 2,6 mblg and depth around 30 km ".

Map

They'll be able to do whatever they want, but eventually they'll have to recognize what's going on. Seismic movements are taking pretty deep at about 25-30 km. They're making quite a noise, they might even have felt weakly in some area. They may indicate what we already know, a possible intrusion in depth under the island, a seismic series is not rising like this. (Enrique)''

''The volcanic monitoring network of the National Geographic Institute (IGN) has detected in recent days a rebound of seismic activity in the southern ridge of Cumbre Vieja de La Palma, has pointed to this digital director of the IGN in the Canary Islands, María José Blanco . He has said that "it is  something to be expected on an active island such as La Palma".

Last Saturday, February 10, reports the IGN, at 23:23 hours "began a new seismic series located in the southeast of the island of La Palma." He points out that "up to the present time (day 12 at 11:00) a total of 9 earthquakes have been located, with magnitudes between 2.2 and 2.6 of magnitude and depth around 30 km.

Specifically, since last Saturday, February 11, there have been tremors in points of the municipalities of Tazacorte, Mazo and Fuencaliente. The last four, until 10:30 am on Monday, February 12, have taken place in the area of ​​El Pueblo (Mazo) and Los Canarios (Fuencaliente). In the surroundings of El Pueblo they have registered at 08.54 hours (2.4 of magnitude and 30 kilometers of depth); at 08.20 (2.3 and 29 km) and at 08.17 (2.4 and 28). In Los Canarios, at 08.50 hours (2.3 and 30 km).

Also, at 07:01 hours, another one was detected in the El Pueblo area (Mazo).  It has been 2.2 magnitude on the Richter scale and has been located 30 kilometers (km) deep. The previous one, of 2.6 magnitude and a depth of 29 km, occurred at 17.01 hours on Saturday, February 11, also in the El Pueblo area. At 16.12 the same day and place was recorded another 2.4 and 30 km deep.

On Saturday, likewise, two other earthquakes were detected. One in Los Canarios (Fuencaliente) at 1:46 pm, of magnitude 2.4 and 28 km deep, and another in Tazacorte, at 13.11 hours, 2.4 and 24 km deep.

Cumbre Vieja is considered to be the most active volcanic area in the Canary Islands.

María José Blanco has told La Palma that there has been "a rebound in seismic activity but it is something to be expected in an active island such as La Palma". "All earthquakes are located at fairly large depths, exceeding 20 kilometers and do not meet the conditions of seismic swarms."

Blanco stressed that this rebound of seismic activity "does not mean anything special" and added that "given the density level of stations that we have in La Palma, the location capacity is very high."

"This situation can be repeated with some regularity," he said. 

Since last October 19, the IGN did not record earthquakes on its official website  associated with the Cumbre Vieja dorsal within the framework of the swarm of vibrations that, during that month, was detected in the outlined environment. That day, after four days without earthquakes, there was a tremor again on the southern ridge of Cumbre Vieja. The earthquake was of magnitude 1.9 on the Richter scale and was located at 02:58 hours on October 19, 9 kilometers deep in the surroundings of Los Canarios, in the municipality of Fuencaliente. It was the shallowest vibration of those counted to date of the seismic swarm that began in the outlined area of ​​Cumbre Vieja volcano on October 7, 2017.''

increased activity of seismic swarm - volcanic in LA Palma, Canary Islands, Spain.- we have 69 earthquakes located in the last 5 days, and in the last few hours the ign has located many more earthquakes in the South side of the island of LA Palma, specifically today, 14 February, have located 53 events between 22 and 27 km deep and there remain several without, we will see when they check. These must be added to the previous days:

- the 3 of yesterday, February 13th.
- the 8 of day 12 February.
- the 4th of February
- the one on the 10th of February

With all these movements, a meeting of the pevolca with scientific and civil protection authorities will be expected in the next few days to explain what is going on and consider the measures if we have to take them. And take the necessary measures, if that were the case. That's what would normally be done for everyone to stay calm and things would be well done. Now, if this goes to more, with more shallow and strong tremors to the pressurise more things change, it is no longer just education and prevention, it is also preparation. And it is that monitoring, education, information and prevention are the four elements that are supported by volcanic surveillance.

By the way in the part edited by ign, the word volcano or volcanic or volcanic does not appear anywhere on the volcanic island of la palma which has a huge old summit volcano, with seismic movement inside, in fact, to be A SEISMIC SERIES, it's very rare. It seems to me a volcanic seismic swarm clearer than water. (Enrique).''

This is what the ign says:
" since the night of Saturday, 10 February, ign has located 69 earthquakes in the environment of the villages of the canaries and the town, the largest of which is 2.6 and depth 28 km. From 1 UTC on 14 February, the activity has increased significantly (53 localized events, the largest of magnitude 2.5) to depths between 25-30 km.

In the results obtained from the GPS network there are no significant deformation of the island of la palma which can be linked to recent seismic activity ":

''The Deputy Minister of Environment and Security of the Canary Islands Government, Blanca Delia Pérez, has convened this Friday, February 16, the meeting of the Scientific Committee for Evaluation and Monitoring of Volcanic Phenomena, as established in the Special Civil Protection Plan and Emergency Care for Volcanic Risk in the Autonomous Community of the Canary Islands (Pevolca), due to the seismic episodes that are happening in the Cumbre Vieja volcano since last Sunday.

The meeting, as it has been able to find out the DIARIO DE AVISOS from sources of the Ministry of Territorial Policy and Environment, will be held simultaneously at the venues of Tenerife and Gran Canaria. In the session the knowledge of the precursors and parameters indicators of the seismic activity in the island of La Palma in recent weeks will be addressed, as well as the assessment of the activity and forecast of its evolution.

In the early hours of the morning tremors have returned to register under the volcanic building. According to the National Geographic Institute, another ten earthquakes have been located between 03:00 and 06:30 in the morning, with magnitudes between 2.1 and 1.5.''

''Cumbre Vieja lives the most important registered seismic swarm''

''At dawn yesterday there were more than fifty tremors in the south of the island, which the coordinator of Involcan blames a process of magmatic intrusion

Early on the morning of February 14, the Cumbre Vieja Volcano registered intense seismic activity, located mainly between the municipalities of Fuencaliente and Mazo, although tremors also occurred in El Paso. More than fifty earthquakes occurred between midnight and 06:30 hours, with a magnitude that ranged from a maximum of 2.5, recorded in Los Canarios, and 1.4, without being perceived by the population.

It is a seismic swarm "more important" than those registered in October 2017 in La Palma, which were also the first to occur in the last 27 years. This has been highlighted by the coordinator of the Canarian Volcanological Institute (Involcan), Nemesio Pérez, who specifies that this swarm is "more important than October, taking into account the number of seismic events detected."

The National Geographic Institute (IGN), which is in charge of volcanic monitoring, located a total of 52 earthquakes. It must be taken into account, as Nemesio Pérez indicates, that in a process of this nature many seismic events may occur, but only locate part of them, so it is likely that more tremors were recorded without being able to locate.

From the Involcan they maintain that the depth of the tremors detected is similar to that of the series that occurred last October. According to the data published by the IGN, the earthquakes were recorded in a strip between 32 and 22 kilometers deep.
The seismic reactivation that began last Saturday, mainly in the southeastern area of ​​the island of La Palma, has not given a truce during these five days, although it took on a noticeable intensity early on Tuesday to Wednesday.''

Statement by Pevolca regarding the activity in La Palma.

Translated.

''A magmatic intrusion at 30 kilometers depth causes the seismic upturn in La Palma''

'A magmatic intrusion about 30 kilometers deep is the cause of the seismic rebound that lives on La Palma Island, after last October, and that has recorded since Saturday a total of 85 localized and 928 detected earthquakes.

This has been exposed to the media by the director of the National Geographic Institute (IGN), María José Blanco, after a long meeting of the scientific committee of the Pevolca (Volcanic Emergency Plan of the Canary Islands) that has met this Friday for about two hours and a half.

Blanco has commented that this phenomenon "accompanies active islands" and from the IGN is "monitoring and surveillance" and any sign of activity is detected, as has happened now, although it is still only seismic and geochemical because they can not be seen deformations on the surface.

"We live in an active archipelago and we had forgotten until the eruption of El Hierro," he said, stressing that on that island there were much more intense seismic processes and finally "there was nothing on the surface."

He said that some kind of eruption could be expected if the magma accelerates, but "it is very far", about 30 kilometers away.

The earthquakes, all of low intensity and not felt by the population, are located mainly in the Cumbre Vieja area, and all the institutions involved are doing a great follow-up, since on the ground there are almost twenty measuring stations.

"NORMAL BUT NOT HABITUAL EPISODES"
The Deputy Minister of the Environment, Blanca Pérez, said that this seismic rebound is deeper than last year, highlighting that it is "normal but not usual episodes", hence the vigilance of the Canary Islands Government. . "La Palma is more monitored than ever," he reiterated.

More news
The seismic activity is reactivated in the Cumbre Vieja volcano
In this line, he announced that at the end of March, the Oceanographic Institute will carry out a new campaign on the island to assess the situation "but nothing indicates that it reaches land or sea".

Pérez also said that if the seismic swarm becomes reactivated, the Pevolca scientific committee will be reconvened to inform the population and make the necessary decisions.''

''The Pevolca predicts that the evolution of seismic activity in La Palma distances, in the short term, the possibility of a volcanic eruption
They attribute the latest seismic series to a new entrance of magmatic material of low volume and great depth.''

''The Scientific Committee of Evaluation and Monitoring of Volcanic Phenomena has concluded in the meeting held today that the data collected since last February 10 on the seismic activity on the Island of La Palma point to a new input of magmatic material of low volume and large depth.

At the meeting, chaired by the Deputy Minister of Environment and Security, Blanca Pérez , representatives of the General State Administration, the National Geographic Institute (IGN); the Superior Council of Scientific Investigations (CSIC); the Canarian Volcanological Institute (Involcan); the Geological and Mining Institute of Spain (IGME); the State Meteorological Agency (AEMET); the Spanish Institute of Oceanography (IEO) and specialists from the two Canarian universities (ULPGC and ULL). Also present were the General Director of Security and Emergencies of the Government of the Canary Islands, Nazaret Díaz, and the Deputy Director of Civil Protection and Emergencies, Néstor Padrón.

The experts analyzed the parameters of seismic activity on the island in recent days and made an evolution forecast that distances, in the short term, the chances of a volcanic eruption on the island.

Since last February 10, the National Geographic Institute (IGN) has detected 928 seismic movements in La Palma and its surroundings, most of them very low intensity, and has located 85 of them , with a depth of between 25 and 30 kilometers , that have not been felt by the population.

Deputy Counsel Blanca Perez stressed that the island "is more monitored than ever" and that already installed instruments will be added at the end of March the Spanish Institute of Oceanography, which plans to conduct a new campaign off the south coast of La Palma to continue studying this phenomenon.

For its part, María José Blanco, director of the IGN in the Canary Islands and spokesperson for the Scientific Committee, clarified that the measurements do not detect deformation in the field and recalled that this seismic activity, which was already lived in the month of October and has now been repeated, "accompany the volcanically active islands."''

(925 seems to be a lot of earthquakes since Feb 10 don't think IGN have listed them)

,,meeting meeting: there is an intrusion of magma in depth and removing iron to the matter, the palm, the canaries.- the usual, white and bottle is hard to deny its content, but as it is deep, nothing Worry for the moment. We have a deep magma intrusion under the old summit volcano on the south of the island of LA Palma, which has led to the latest seismic-volcanic movements in the southern part of the island of LA Palma. So far, you know, but now that it happens?. We have three possible answers.

1-stops and does not move again in years (unlikely < 5 %)
2-continue to be small intrusions and swarms increasingly spaced out in time. (fairly likely > 80 %)
3-continuing to have intrusions, becoming more frequent and more seismicity, indicating a process and marking the path to an eruption that could be in months or years, even tens of years if they occur relatively large among some Intrusions, as a step before the 1949 eruption) (low probability < 15 %).

Now to see what happens and above all to watch over the island and wait to see if they report more rigour and some more data to reassure the population, without blackouts like now. At the moment they look miracle some earthquakes today 16 February without locating by ign like these five at 00:38, 00:42, 01:19, 01:24 and 01:31 between how little it looks In the spectrogram. Let's see if when they check, they put something. By the way, yesterday, 15 minutes before midnight, there are many different lines of a small swarm, of which there is nothing at all.

This meeting has certainly been productive and has said what is going on and what will happen. That If, the measures to reduce the importance or remove iron to the subject as "Small intrusion", I suppose it will be for not measuring GPS deformation or being this very small, but I am more inclined to think of a political theme to include this type of Adjectives, because at that depth it is very difficult to know whether it has been large or small.
