Many thanks for posting the updates Tamara and surprised to see a 3.4 so near to Fuerteventura .

Hello Jand
I haven't had any joy with this link for a couple of days now: http://www.ign.es/ign/resources/volcanologia/tproximos/canarias.html
Hope the server wasn't sitting on a volcano that 'blew'! Is there another site we can use or do you know if that one is due back online soon? Thanks.

Hi Tamara

The link to IGN I have always used is down I will try and contact other people I keep in contact with to see if they know whats happening or if they have another link to IGN.

Had a lovely cruise we passed the Cape Verde islands and was amazed how much the landscape looked like the Canary Islands lots of volcanoes to see .

A little after one remarkable of magnitude 3.0 to the northeast of the Palma 30 km deep and a last of magnitude 1.4 in the same area, something closer to the island without depth.

They record gases in the volcano Dorsal, Tenerife
The experts analyze the "anomalous emissions" of carbon dioxide that "suggest the occurrence of processes of magmatic degassing"

..A study on the diffuse emission of gases reflects changes of activity in the volcano Dorsal Noroeste de Tenerife , according to an investigation of the Volcanological Institute of the Canary Islands.

This research by Involcan, which has been published in the international scientific journal 'Bulletin of Volcanology', shows that the variations of the diffused emissions of carbon dioxide recorded in the volcano Dorsal Noroeste de Tenerife during the period 2000-2016 are due to changes Of activity that has undergone this volcanic system in depth.

This relationship between the emission of gases and volcanic activity in the North-West of Tenerife is supported by the results obtained from 49 scientific observation campaigns on the diffuse emission of carbon dioxide (CO2) by the volcanological group of ITER, now Forming part of the Involcan, during the last 17 years.

Involving, in a note, explains that for the realization of these scientific campaigns have been made about 18,000 measures of diffuse flux of carbon dioxide in hundreds of measurement and observation points spread over an area of ​​approximately 75 square kilometers of the Northwest Dorsal Volcano Tenerife.

This active volcanic system, also known as Dorsal Bilma-Abeque volcano, has 46 volcanic cones and has been the scene of three of the six historical eruptions in Tenerife (Boca Cangrejo in the 16th century, Arenas Negras in 1706 and Chinyero in 1909) .

The diffuse emission of carbon dioxide in the selected area has shown a range of values ​​between 52 and 867 tons per day, and its average normal or bottom value has been estimated at 143 tons per day .

The detection of emissions exceeding 400 tonnes per day has been observed during the 2004-2005 earthquake crisis , before a significant increase in microsisicity in Tenerife from the end of 2009 until mid-2011 and before the swarm Registered on October 2, 2016.

Involcan indicates that these anomalous missions of carbon dioxide suggest the occurrence of deep magmatic degasification processes in the Dorsal Northwest volcano of Tenerife, most likely as a result of changes in ground stress associated with the anomalous seismic activity periods recorded in Tenerife and its surroundings .

Although diffuse emanations of carbon dioxide reflect an important fraction of carbon dioxide mixture) of organic and atmospheric origin, as shown by the analysis of the isotopic signature of carbon dioxide (CO2) in the soil atmosphere, these Diffuse emissions have quantifiable fractions of carbon dioxide of volcanic origin that support these observations.

The note notes that this time series on the diffuse emission of gases in the Dorsal Northwest volcano of Tenerife is the seventh largest in the world that has been made in an active volcanic system and has only been surpassed by studies of diffuse emission of gases in The volcanic systems of Vesuvius and Vulcano (Italy), Mammoth Mountain (USA), El Hierro, Cumbre Vieja and Teide (Canary Islands, Spain)...

REPUBLIC / EP | 04/24/2017
A team from the Faculty of Earth Sciences at the Universitat de Barcelona (UB) and the Marche Polytechnic (Italy) has discovered a new bacterial species ('Thiolava veneris') in the Tagoro submarine volcano erupted from an eruption Volcanic eruption in the waters of the island of El Hierro (Canary Islands).

Bacteria
The new bacterial community, described in an article in the journal Nature Ecology & Evolution, has been found 130 feet deep and forms an extensive microbial filaments covering 2,000 square meters near the top of the volcano.

"This is the first known bacterial species to be discovered associated with the volcanic activity of Tagoro", an eruption that began in October 2011 and is a natural laboratory for biology and earth sciences. college.

Since then, the Grup de Recerca Consolidat (GRC) of Marine Geosciences of the UB has promoted several scientific studies that have revealed unpublished aspects about the origin and evolution of the volcanic islands.

This bacterium represents a new genus and species of extremophilic bacteria, unknown until now by the scientific community and, according to the images of an unmanned submarine vehicle directed by remote control, the new bacterial habitat covers about 2,000 square meters of the Tagoro volcano - between 129 And 132 meters deep.

This species is close to other marine bacteria that show a great metabolic plasticity to adapt to extreme environments of the ocean floor.
