Between Tenerife and Gran Canaria hides an underwater volcano called ‘Enmedio’. The CSIC has just detected activity for the first time

by

Under the waters of the Atlantic, about 80 kilometers southwest of Tenerife and Gran Canaria, hides a colossus that we often forget about. Is called ‘Enmedio’, a name that has quite a joke behind it, but which is nothing more than an underwater volcano with a base of 3.5 kilometers and whose summit is 1,625 meters deep. And although it has been there for a long time, now a scientific team has detected for the first time signs of hydrothermal activity in its depths. A decade. It has not happened overnight, since the team of geologists has spent almost ten years collecting multidisciplinary data driven mainly through the VULCANA project. And the results of the measurements made between 2015 and 2024 now have ended up published in the magazine Bulletin of Volcanology. Here, through oceanographic campaigns that combine high-resolution bathymetry, seismic and geochemistry, scientists they have managed to confirm what until now was only a suspicion: the volcano has an active circulatory system. What have they found? What the team has confirmed with all this information is that there is low-temperature hydrothermal activity at this location. In simple terms, we can now see that the volcano is releasing fluids through a series of fractures and a depression that is in your franc. Although this does not mean that it will erupt in the next few hours. In order to make estimates, it was decided to analyze the water in the vicinity of the volcano, and here the instruments recorded thermal anomalies of up to 0.5 ºC above normal. That is, the water around the volcano was hotter and was also loaded with nutrients such as ammonium or iron oxide, which causes biological alterations in the rocks in the area. There is no rash. Logically, when we read ‘volcanic activity’ and ‘Canary Islands’ in the same sentence, it is inevitable to think about volcanic eruptions such as that of Cumbre Vieja in La Palma, and even more so taking into account the recent earthquakes in the area. However, the CSIC has been quite categorical in this regard, pointing out that this detection does not indicate an imminent eruption and has no relationship with the recent seismic swarms recorded in the area around Teide. A paradise. In this way it is an endemic and latent process. In fact, these hydrothermal vents are excellent news for deep ocean biodiversity. To understand it, we can look back to see how the Tagoro volcano ended up fertilizing the post-eruptive marine ecosystem. Now, Enmedio’s fluids act as a chemical engine that influences the composition of the local ocean and feeds communities of microorganisms that thrive in the most extreme conditions of the seafloor. And although the Enmedio volcano is not a new discovery, this first evidence that it “breathes” marks a before and after in volcanic monitoring in Spain. It demonstrates that under water, more than a kilometer and a half deep, the Canary Islands continue to be an incomparable natural laboratory that, thanks to science, we are beginning to understand better than ever.

It will not have a garden but a “false volcano”

by

When someone has enough economic power to use their “private jet” to approve a local airport As an international airport, the minimum that is expected is to stay in the best mansions of the places you visit. However, when This is the emir of Qatarwhat is expected is not only that you stay in them, but that you buy them. Tamim bin Hamad Al-Thani, current emir of Qatar, sounds like the main interested party in Villa Certosa, one of the most famous mansions (and more extravagant) of Sardinia, which for years has been owned by Silvio Berlusconi since the 70s, and now from his heirs. ​A garden with a private volcano Villa Certosa is located in Porto Rotondo, on the northeastern tip of Sardinia, overlooking the Gulf of Marinella, and it’s huge. Built on an area of ​​120 hectares of land, it has 4,500 square meters distributed in 126 rooms. The most striking curiosity about this mansion is not its hundreds of rooms or its enormous 50-hectare garden with ancient olive trees. In this farm the “star whim” It is an artificial volcanodesigned to spit fire and smoke and turn the landscape into a spectacle. The architect got out of hand with the science experiment. The artificial volcano is part of that idea of ​​a “theme park” that Berlusconi had for his villa. In 2006, the Italian tycoon ordered to build an artificial hill about 10 meters in the middle of your property. That generated controversy and led to an investigation into the area’s landscaping regulations. Under this hill something much more explosive was hidden. As and how I collected Europa Presson the night of August 15 of that same year, the Italian politician and millionaire pressed the power button on his volcano as the culmination of one of the usual parties that were organized in the mansion. The noise was such that the neighbors called the firefighters, Civil Protection and the Forestry Corps after seeing the lava explosions and the fire coming out of that artificial hill. Beyond the artificial volcano, the farm adds very striking details: a (false) Roman amphitheater by the sea with capacity for 300 people, a sea cave with a pool and a Poseidon mosaic, four additional pools spread across the estate and a underground bunker nuclear grade. ​Berlusconi bought the property when it was still known as Villa Monastero in the early 1970s and transformed it with architect Gianni Gamondi. Over time, Villa Certosa became a common scenario of political and media visits. within its walls political figures stayed top level such as George W. Bush, Vladimir Putin or Tony Blair, as well as Spanish politicians who coincided with Berlusconi’s time in political life, such as José Luis Zapatero and José María Aznar. The emir rules in Qatar, but looks at Sardinia Tamim bin Hamad Al-Thaniemir of Qatar, is the visible head of one of the richest and most powerful families on the planet. It is estimated that the Al Thani dynasty manages a joint fortune that exceeds 335,000 million dollarswhich makes the purchase of a 500 million mansion something perfectly affordable for your pocket. In fact, the emir is already a regular on these coasts, where he usually sails with one of his superyachts, the Al Lusail, his impressive yacht 123 meters long, also valued at 500 million dollars. His interest in the area is not limited to summer tourism, since through sovereign funds controls several hotels historical luxury hotels on the Costa Smeralda such as Cala di Volpe or Romazzino. Regarding the possible purchase of the villa, from the surroundings of the heirs of Il Cavaliere They wanted to be prudent. A spokesperson for Fininvest declared to Euronews: “We are collecting several expressions of interest, but at the moment there are no negotiations at an advanced stage. We do not comment on individual interlocutors.” In Xataka | A single millionaire spent the equivalent of 10,000 tourists on his luxury vacation in Mallorca: the Emir of Qatar Image | Wikimedia Commons (Khamenei.ir)

The Virgin appeared inside a volcano in La Garrotxa. So they built one of the most special hermitages in the world

by

I confess that one of the buildings that fascinates me the most is that of the hermitage. There are some as spectacular as the one in Virgin of the Castle in Chillónbut others are four almost dilapidated walls in remote places (or locked in a Madrid roundabout). They are scattered throughout our geography, sometimes extremely hidden, to the point that there is one that crowns a spectacular landscape. It is the hermitage of Santa Margarida de Sacot, in the Garrotxa. And it is in the center of the crater of a volcano. Santa Margarida volcano. Of all the volcanic areas of the Iberian Peninsula, Garrotxa is one of the most spectacular. As in other volcanic areas, we can perfectly see the cones of the volcanoes that erupted thousands of years ago. But, unlike places like Campo de Calatrava, the Garrotxa It is dyed green thanks to its vegetation. It is estimated that the volcanic activity in the Garrotxa Volcanic Zone Natural Park It expanded from 700,000 years ago to 8,300 years ago, with the Santa Margarida volcano being one of the youngest of the 40 cones that make up the area. From a drone view, the volcano is imposing, but it is striking that the interior of the crater is a treeless meadow and has a building right in the center. A hermitage would be good. Places of worship are not usually planted in a random place and, as tradition says, the hermitage that shares its name with the volcano was built when someone discovered something miraculous: an image of the virgin carved in alabaster inside the crater. It was clear: a building had to be built to honor such a miracle. Although the first documented reference to the hermitage is from 1403, when money was allocated to maintain the chapel, it is estimated that this Romanesque building would have been built at some point. moment from the 13th century. The picture is impressive The church is ruined. The miracle of the virgin could not be repeated to save the hermitage from the effects of earthquakes that shook the area in 1428. Known as “Terratrèmol de la Candelera”, a series of tremors with an estimated magnitude of between 6.5 and 7.3 knocked down several buildings, the hermitage of Santa Margarida one of those who ended up badly off. Something was saved: the image of the virgin carved in alabaster, which is currently kept in the Diocesan Museum of Girona. In 1865 decided that something had to be done with the place and they rebuilt the hermitage. They did so by building a single-nave structure that preserves something of the original: the semicircular apse and the porch, and inside it, a replica of the alabaster carving. deep symbolism. Since then, and as it has been doing for 400 years, the hermitage of Santa Margarida governs the center of the homonymous volcano and is part of the Natural Park. If you feel up to it, you can visit it, but you will have to do some hiking. The car is left on the edge of the volcano and it is necessary to continue on foot along a well-marked path until reaching 766 meters of altitude. That is the perimeter of the crater, 2,000 metersand to reach the hermitage, we have to descend a little to 682 meters, where we finally have the place of worship surrounded by a green meadow. For many, it is surely simply another fascinating place in our geography, but for many others it is possible that stopping in that place awakens the feelings that led those who built the hermitage in the Middle Ages: a deep connection with the divine. What is evident is that, whether we have that connection or not, the landscape is impressive and seeing a construction in the center of a volcanic crater is a powerful image. And if there is not much tourism, a moment of retreat and disconnection from everyday life.

The eruption of a volcano was synonymous with danger 100 years ago. Today has made Iceland a theme park

by

Exactly one year ago, Iceland took a unexplored path In his fight against mass tourism: in essence, tell the truth to the visitor. Thus began a marked campaign For a slogan: “No one will save you if you fall”, which unequivocally came to confirm the hordes of the dangers of getting too close to an erupting volcano. Today, Iceland wonders if it was worth “opening” both the world. The awakening that changed everything. In 2010, when Eyjafjalajökull volcano interrupted air traffic European with an ash cloud that paralyzed the continent, Iceland went from being a remote island and evoked in Nordic sagas to become a global stage. The images of glaciers, black beaches and hot springs spread by international chains aroused the curiosity of the world in a country that had just suffered the blow of The financial crisis. With the campaign Inspired by Icelandthe government and tourism industry They took the moment. From then on, the landing of low -cost airlines and Viral phenomena In social networks (including a Justin Bieber video clip between waterfalls and aircraft remains) they catapulted the island to essential destination. Mass tourism. In just fifteen years, the number of visitors went from less than half a million to More than 2.3 million annuallymultiplying the local population several times during the high season. Tourism revitalized villages, generated employment and transformed the economyto the point of becoming the Main motor of the country. Locations Like Vikonce agricultural, they saw how the stables gave way to guest houses, improvised coffees in school bus and attractions of adventure. Immigration accompanied This boom: in some municipalities, foreigners are already a majority, and the arrival of new residents has even caused an unexpected “baby boom”. For many mayors and local businessmen, current problems are preferable to the decline of peoples that previously seemed condemned to abandonment. The identity dilemma. However, obviously not everything is good news. Tourism has contributed economic vitality, employment and infrastructure, but also tensions. Farmers complain about visitors who enter their lands or feed horses without permission, even causing deaths of animals. In Vikthe massive arrival of foreign workers has altered the social and urban fabric, with prefabricated homes that change traditional aesthetics. Even in schools they have had to Put posters to prevent tourists from photographing children. In the environmental plane, basic systems as the sewer They have been overwhelmed. Many Icelanders recognize the prosperity that tourism has given them, but they wonder how much local culture can resist without diluting. Iceland as theme park. More than a decade later that Eyjafjalajökull Cover the European sky with ashes and put the country on the global map, many critics argue that the island has run the risk of becoming in a “volcanoes theme park.” The geysers, glaciers and mountains of fire are today part of an itinerary Almost prefabricated, driven by low -cost airlines and Instagram selfies, which concentrates crowds in a handful of iconic landscapes while other regions remain outside. What was previously perceived as an indomitable and mysterious territory has become a tourist decoration subject to the logic of rapid consumption, where the eruption that attracted the world was transformed In advertising claim permanent. For many Icelandic, the paradox is evident: the volcano that saved the economy now threatens to devour the essence of their country. The future. Thus, academics and analysts propose Diversify the routes and offer deepest experiences linked to the history and culture of the country, to prevent tourism from reduced to a handful of “postcard places.” Regions such as Western Fjords or Fisheries North are still relatively on the sidelines, although the opening of direct flights could change the situation. The issue, according to many Icelanders, is not to close the door to visitors, but rethink the model: Attract those who want a longer and more conscious experience, instead of fast visits dictated by social networks. The national phrase Þetta Reddast (“Everything will work out”) reflects the resilient optimism of the country, although now faces the most uncomfortable question: Can Iceland continue to receive the entire world without sacrificing what made it unique?

The Canary Islands gave 24 tons of sand from La Palma volcano to Madrid. Now Madrid doesn’t know what to do with them

by

Madrid has 24 tons of volcanic sand of the palm with which he does not know very well what to do. It sounds strange, but that is the peculiar outcome with which the consular and capital governments have been found after an initiative designed to value the Canarian cultural heritage in the Peninsula. The idea worked, but has ended up leaving that peculiar inheritance: bags and more bags of dark ash that accumulate dust (and controversy) without a clear destination. We explain ourselves. Presuming culture. May 17 was a day to frame in the history of Canarian culture. Or at least in one of its most popular disciplines: The Canarian fighta sport that hurts its roots in the first settlers of the islands. His practice is very popular in the archipelago, but not so much out. Hence, on May 17, as part of the Month of the Canary Islandsthe Government promoted A milestone In the discipline: the first day of official Canarian struggle in Madrid. FIGHTERS AND MUCH (MUCH) ARENA. For the appointment, fighters of the Saladar de Jandía and the Candelaria de Mircatwo key teams of the discipline that were measured in the twentieth day of the DISA Tournament of the Canary Islands. And something else: tons of volcanic sand transported from the palm to cover the pitch. The idea was to give even more epic to the appointment carrying a piece of the Canary Islands (literally) to Madrid and deploying it in the middle of Callao, where the Canarian fighters were measured. A 24 tons “ring”. The idea worked. The photos Shared by the Canarian government (with volcanic sand covering callus) they are fascinating and also show that the appointment attracted a good handful of curious. To host them, even a portable stand with capacity for 200 spectators. The event was also attended by President Fernando Clavijo along with regional positions and representatives of the institutional, sports and social life of the archipelago. In case that was not enough, the Executive took care of the last detail. Any type of volcanic sand was not transported to Madrid. No. The authorities chose ashes from the island of La Palma that were generated during the Tajogaite eruption In 2021. “The youngest of the islands, chosen as a symbol of identity, roots and renewal,” the Canarian government insisted in its community. In total some mobilized some 24 tonsaccording to the institution itself. And what happened to that sand? The fight was held on May 17, Jandía’s Salader won the Candelaria de Mirca in a fierce encounter (12-10), but … and then? What happened to tons of volcanic sand? That is the question that was asked recently eldiario.es, which after consulting with the Madrid City Council reached an amazing conclusion: the bags seemed to have vanished. “Without a trace of the 24 tons”, He titled The newspaper. The news was even more striking because, as confirmed by the regional government, the agreement contemplated that, after the May fight, the 24,000 kilos of ash were ceded to the Madrid City Council so that it could cover with it the fields of beach volleyball. From the Consistory they assured however not to have proof of that initiative. I wasn’t dead … It was not the last chapter of the curious soap opera of the traveling volcanic sand. On Saturday Eldiario.es published again Another revelation About the 24 tons of Tajogaite: the material was not lost by Madrid, but stored in work bags in a Torrelodones industrial ship. The reason? Although the initial idea was to allocate the sand to Madrid Volleyball courts, the authorities of the capital came to the conclusion that it was not a good idea to give it that use. His grains may serve for a Canarian fighting fight, but in the opinion of Madrid technicians they tend to heat up easily, which led the authorities to rule it out for the courts. And what will it be used for? It doesn’t seem to be very clear. At least according to the information handled by eldiario.es, which ensures that the Department of the Environment is looking for an adequate destination for the Canarian gift. The bags are also waiting for the Consistory Ultime for a collaboration agreement to accept the material, which, a priori, will have environmental use. In the authorization of the Cabildo it is noted that the material “lacks commercial value”, although as He put value The Canarian government does have a symbolic value.

In 2021 a volcano spent three days in eruption without anyone finding out. Now it helps us ahead of the silent volcanoes

by

Knowing how to read the signals that a volcano gives before erupting can make a difference between a scare and a tragedy. Some volcanoes make it easy for experts who know how to read these clues but others erupt without prior notice. Or maybe just we couldn’t decipher your signs. At least until now. A new tool. A team of researchers He has devised A new mechanism to model the behavior of some volcanoes. This tool, its creators stand out, will serve to more effectively monitor the eruptions of some volcanoes reducing the risk associated with these natural phenomena often so violent. Some special usefulness in the case of “silent” volcanoes. “Despite great advances in monitoring, some volcanoes erupt with minimally detectable or even without them precursors, significantly increasing the risk of nearby populations,” pointed in a press release Yuyu Li, co -author of the study. As explained by LI herself, some of these volcanoes are located not only near communities, also near important air traffic routes. Silent volcanoes. For the development of its tool, the team resorted to the Veniaminaf volcano, located in the North American state of Alaska. This is one of the so -called “silent” volcanoes, volcanoes whose eruption is not preceded by the signals that are generally associated with an imminent or close eruption, such as earthquakes or the deformation of the soil in the surroundings of the Magma Chamber. Veniaminof’s is just an example that We can find In this family of silent volcanoes that also includes some closer such as Stromboli in Italy or Popocatepetl in Mexico. Looking inside the volcano. But among all of them, the Veniaminof volcano is perhaps the most paradigmatic. Not because only two of the 13 rashes that have leaded since 1993 have been planned, but because in 2021 he achieved the milestone of erupting without anyone noticing Until three days later. The team responsible for the study analyzed the internal conditions that make it a silent volcano. Factors such as a slow supply of magma and a warm host rock are key in this regard. The monitoring of the volcano was carried out for three summers prior to one of the silent eruptions of the volcano, that of 2018. A model to get ahead of the eruption. The result, a model that conforms to the state of different variables that can condition the probability of the burst of the magma, such as the volume of the reserve, flow conditions of the magna, depth of the reserve or the form that it acquires is. Thus they could estimate what kind of conditions could be linked to a silent eruption and which ones were not. The team found that soil deformation could help prevent some eruptions of the volcano but that the relationship between underground magma and rashes were somewhat more complex than it might seem. The details of the study have been published In an article In the magazine Frontiers in Earth Science. The following steps. Monitoring the numerous silent volcanoes distributed throughout the world will not be an easy task. For now, the resolution gives a clue to what are the volcanoes to monitor more closely: volcanoes with small and warm reserves and slow magma flows, explains the team.
