A question has been asked to Enrique regarding his comment on the above post '' Es difícil empezar este post, me ha costado,''   ''It's hard to start this post, it cost me, ''

The question:

''Una curiosidad Enrique, ¿por qué ha sido difícil, por qué te ha costado el post?''

''A curiosity Enrique, why has it been difficult, why did the post cost you?''

Awaiting for a reply from Enrique.

The reply from Enrique:

''Hola Chane, me costo por que ayer hice muchas cosas y era tarde, y basicamente es una cuestion de tiempo, ordenar los datos, ver lo que ha cambiado del catalogo, ver los sismogramas, abrir los archivos de fase e intentar comprender lo que pasa con los pocos datos que llegan. No es una tarea facil. Un saludo. (Enrique desde el movil)

Hi, I cost because yesterday I did a lot of things and it was late, and basically it's a matter of time, order the data, see what's changed from the catalog, see the seismograms, open the phase files and try to understand what's going on With the few data coming. It's not an easy task. A greeting. (Enrique from cell phone)''

With regard to yesterday 02 April, 3 New earthquakes have been located in the interior of Tenerife and there has been some further north of the volcano in the middle of which it falls from 2.3 to 2.1 and is It's less deep from 16 to 9 miles.

From yesterday they have re-examined the n ' n ' n's earthquake, and it has done it again, and it has been in the interior of the island, almost under the summit area and losing more depth and depth over 1.7 1.2 and now from 1.2 to 0. 7... the truth is that it seems to me a lot, the network is not very fine with the gap of 254 it is not very precise, but something weird is or has changed dramatically something, it's a lot of variation.

Thank you Tamara for all your time spent and the updating of the activity .

Wow that looks like some ongoing swarm around Volcano Enmedio since the 28th April wonder if the 3.2 earthquake has something to do with this.

Registered a series of 50 earthquakes in 24 hours between Gran Canaria and Tenerife

The tremor of greater intensity has been 3.2 on the Richter scale
Laprovincia.Es 30.04.2018 | 20:22

In just 24 hours - from 16.55 last Sunday until the same time on Monday - a total of 50 seismic movements have been recorded between Gran Canaria and Tenerife . In addition, the waters separating the eastern islands of Fuerteventura and Gran Canaria were the site of the largest quake in the archipelago, with a force of 3.2 on the Richter scale .

Among the capital islands, the most relevant seismic movements have occurred closer to the Tenerife coast and during the early morning, when the three most powerful tremors reached a force of 1.9 degree; 2; and 2.1 on the Richter scale. These tremors have not been felt by the population and are quite frequent in the Canary region and its waters.

According to the director of the National Seismic Network of the National Geographic Institute (IGN) , Emilio Carreño, earthquakes registered in the Canary Islands are of tectonic origin, who " are not usually associated with volcanology" and that " it is not unusual" increasing These tremors during the past weekend.

"Right now in the Peninsula there are quite a few places in which these series are given, it is common , that perhaps during a month they register between 100 and 600 earthquakes as in the Jódar area, in Jaén, which must have already been given between 400 and 500 and, at the same time, we have another open in Murcia that has frequent series that then disappear, "he stressed.

Carreño has pointed out that all earthquakes are revised, especially those of the Canary Islands because "the situation of the islands makes precision in locations more difficult", and that they are done both in the Seismic Network and in the Volcanology Group.

Latest report courtesy of  Avcan regarding the swarm near Volcano Enmedio.

''Seismic Swarm between Tenerife and Gran Canaria (Acualización)

It continues the seismic swarm that began on the afternoon of 29 April at 16:00 UTC and which is located between Tenerife and Gran Canaria. The Canary Seismic Network (Involcan) has already detected some 200 small earthquakes of which 200 have been located.

The area where this seismic swarm has been recorded is the area where most of the seismicity recorded in the canary islands is usually concentrated. The largest of all has reached the magnitude 2,5, although almost all of them remain below magnitude 2. Throughout the day, we will continue to update the data obtained.

Photo Caption: seismicity located by the canary seismic network for the last 30 days. Most of the seismicity located between Tenerife and Gran Canaria is related to the current seismic swarm that began on April 29 The size of the circles reflects the magnitude of the events and the colour of them the depth of them.''

Latest report by Enrique regarding the earthquake swarm.

''seismic swarm in the volcano area of between Tenerife and Gran Canaria, Spain. 01/05/2018-16:00 H.- a volcanic cone of 500 meters deep submerged in the bottom of the sea on a bottom 3000 meters below sea level make this small cone called the " son of Tenerife " or " Volcano in the middle " the protagonist of the seismic activity that we have these days.

This volcano is born on the crossing of two major faults that pass through that place. One of them, which is almost oriented in direction ne-SSW is giving rise to an important seismic series, with more than 200 events recorded from 16:00 UTC (17:00 canarian time) of 29 April 2018. The Ign Recorded 213 events and located about 50 earthquakes in the catalogue. Involcan has registered some, around 200, and has located around a hundred earthquakes according to the latest data.

According to ign, the largest of all earthquakes has reached the magnitude 2,2 and another 2.1, being the others below the magnitude 2. The very variable depth between shallow and 52 km deep. The location is very dispersed, indicating that the network does not locate the epicenters well, a is needed for a better location. In fact, 2.2 presents a gap of 234, i.e. above the 200 value which is the maximum to be considered as well located, indicating that it is not well covered by the seismic network.

According to involcan, the largest of all earthquakes has reached the magnitude 2,5, although almost all remain below magnitude 2. There is no more data at the moment.

For dessert also today we have a small volcanic seismic swarm in the cañadas del teide, with a bit of seismicity located in the southwest area of pico viejo in the area in the boiler caldera about 9-12 km. (Enrique & Isaac)

This link is really interesting it will need translating but it has  photos and maps relating to Volcano Enmedio.

Partly translated.

''EBFNews.- The scientific group that integrates the Vulcano project of the Spanish Institute of Oceanography (IEO) and is in charge of evaluating the impact of the submarine eruptive process on the island of El Hierro on its marine ecosystem, has just published an extensive file descriptive of the so-called Enmedio volcano, a document that summarizes the most relevant geological features of this famous and at the same time unknown volcano even in the depths of the ocean.

According to the researchers through the Vulcano website, it is a volcano son of Teide (Tenerife) that was discovered in 1993 by volcanologist Hans-Ulrich Schmincke in the framework of the Meteor campaign. This researcher located its base at 2,300 meters, with a height of 600 meters, so its peak would be 1,700 meters deep.

Later, in 1995, and with the participation of the IEO, a new bathymetry was carried out, in which a secondary cone was spoken for the first time ("of 1.5 x 1 km of base and a height of more than 100 m. "). However, now thanks to this new research phase, more revealing data have been obtained.

Scientists determine that the Son of Tenerife volcano is between the islands of Tenerife and Gran Canaria at the geographic coordinates are 28º 05 '24' 'N and 16º 10' 1.4 "W.

In the new, more precise bathymetry, the IEO locates the depth of the base of the volcano at 2,100 meters and its summit at 1,630 m under the sea, with a maximum height of 470 m. The major axis of the base of the volcano is 2.88 km while the minor axis is 2.36 km.

Multiteide are updating every 6 hours the ongoing swarm.

''The Low-magnitude seismic activity is continuing between the islands of Tenerife and Gran Canaria. Until this time and since Sunday 29 April, 213 earthquakes have been detected, of which the largest and continuing to work on the location of the less energy.

Information at http://www.ign.es/web/resources/volcanologia/html/CA_noticias.html
And at http://www.ign.es/web/resources/volcanologia/tproximos/canarias.html

We show the event histogram every 6 hours.''

Seven earthquakes already since midnight the depths of all of them are deep which I think (but may be wrong) that shows something Magma ? is moving under the islands.

Update on the swarm by IGN :

Translated.

''Information concerning the seismic series between Tenerife and Gran Canaria launched on 29 April. (http://www.ign.es/web/resources/volcanologia/html/CA_noticias.html)

It continues to detected seismic activity in the form of low-magnitude earthquakes, located between the islands of Tenerife and Gran Canaria. Until this time and since Sunday 29 April, 262 earthquakes have been detected, of which 81. Have been located and continue to work on the location of smaller earthquakes.

The distribution of earthquakes runs in a ne-Ssw alignment, with a length of approximately 30 km, although the low magnitude of events is the main cause of the high degree of uncertainty in their location. Once the series is finished, joint localisation techniques may be applied to improve location.
Analysis of the wavelength of earthquakes shows a high degree of correlation, thereby showing their common origin. Parameter b of the-Richter act has been calculated for the series, which up to now reaches a value of 1,35 ± 0,14, which corresponds to a swarm series, with a magnitude of 1,3 completeness. Mblg. The Elastic Energy released in the form of earthquakes to this moment in the area is 1,66 × 109 J, which is roughly equivalent to the energy released by a single earthquake of magnitude 3,0 mblg.''

Seismic Swarm between Tenerife and Gran Canaria (update 17.00 hours on may 3)

Of the more than 250 earthquakes detected by the canary seismic network (Involcan), 158. Have been able to locate 158. On the map showing all the earthquakes located from the beginning of the swarm, and featured in blue color those that They have occurred in the last 24 hours and have also been localized by our stations.

In addition to the distribution, the distribution of the hypocenters of all of them is also shown. The size of each circle is determined by the magnitude of events, which continue in any case to be low.

To major on the map, the stations of the canary seismic network (Involcan) are shown, being identified with a triangle.

We continue to work to provide more information throughout the day on the evolution of the swarm, which remains focused between the two islands, where most of the seismicity recorded in the canary islands is normally concentrated.''
