eruption

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?

74,000 years ago, a volcanic eruption led humanity to the edge of extinction. We begin to understand how we survive

by

74,000 years ago, in a remote lake north of Sumatra, a volcano erupted. But it wasn’t a normal volcano. According to archaeologist Jayde N. Hiniak“The Toba expelled 2,800 cubic kilometers of ash to the stratosphere, created a crater of 1,000 soccer fields” and caused a global winter. That could take our species to the edge of extinction: for more than half a century, many anthropologists are convinced that it was that eruption (one of the greatest known eruptions) that reduced the human population to about 10,000 fertile couples. It would be the most critical moment of Homo Sapiens since it arose. It is true that the theory is controversial and the debate around the real climate change that the Toba created is still very alive; However, no one doubts that what happened that day in Sumatra was a huge catastrophe. And that can be seen in archaeological remains. As Hiniak pointed out“Most archaeological sites show a history of resistance.” In areas such as South Africa or the lowlands of Ethiopia these climatic changes led to the adoption of technological innovations such as the development of arches and arrows. In much closer places (such as Indonesia, India or China), the population also suffered deep changes that allowed him to survive. All this can be known because the Toba left many geological samples distributed throughout the world. Studying the deposits before and after the ash of the volcano gives a lot of information on how these societies changed socio-technologically. The flexibility was key. Regardless of what Toba will cause (or not) drastic reduction Of the population, what is clear is that it allows us to draw conclusions about what was the fundamental feature that explains the survival of human communities: behavioral flexibility. Something that allows Image | Tetiana Grypachevska In Xataka | When Newton reached the fundamental laws of physics there was already a sign that said “Leonardo was here”

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.

In case they were happening few things, the sun has just caused a radius blackout with its most powerful eruption of 2025

by

The sun has decided to remind us that we are in their hands. A new active region of sun spots, called AR4087, has released this morning a solar eruption of class X2.7, the most powerful so far this year. The sun was not asleep. Eruptions, glows or solar flares are classified as Five categories According to its intensity: A, B, C, M and X. Each letter represents events ten times more intense than the previous letter. An eruption X2.7 is located at the lower end of the most powerful category, but remains an important and unusual eruption. Observatories that constantly monitor the solar crown They detected it on May 14 at 08:25 UTC (10:25 in Spain). The X2.7 class flares has been the strongest of 2025, demonstrating that the sun is still awake After last year’s activitywhen it reached the solar maximum. Radio lock. Although it was not directed directly to the Earth, the eruption launched an intense X -ray pulse and extreme ultraviolet radiation that reached our planet at the speed of light. When impacting with the upper atmosphere of the Earth, this radiation has rapidly ionized, interfering with the high frequency radio signals (HF) on the visible face of our planet. As a result, a R3 level radius blackout was detected (cataloged as “strong”) in Europe, Asia and the Middle East. The show begins. The sun stain AR4087 remains very active and Soon he will look directly to the Earth As the sun revolves on its own axis. In the last hours he has produced class rashes M5.3, X2.7 and M7.74. The big question now is whether the most powerful eruption was accompanied by a coronal mass ejection, the famous solar plasma and magnetic field languages ​​that, when impacting with the Earth’s magnetic field, can cause geomagnetic storms and intense auroras to different latitudes, Like the historic Red Auroras of 2024. At the moment, the AR4087 region is at the visible edge of the sun, so the earth seems to be out of reach.

In full eruption of Etna, Italian emergency services have encountered an obstacle: tourists

by

ETNA is more than one of the volcanoes more active and high from Europe. It is also a tourist claim. One that seems to work especially well when, as these days, it offers a fascinating show that mixes A lava river, snow, ashessteam and smoke columns. The power of his eruption has attracted hundreds of visitors And curious, leaving a flood of people who already supposes a headache for the authorities. The reason, simple: they have reached Block the tracks They need to operate rescue services. It is nature … and it is Tourist. The Etna volcano, under the spotlights. The Italians have been pending Etna for more than a week, the volcano located on the east coast of Sicily and one of The most active from Europe. His activity intensified days ago, with A fracture of the Crater of Bocca Nuova, and has left a succession of Explosions and lava flows They have spread through the mountain, forming an extensive lava river. Volcanic activity also affects communities. Yesterday the Catania airport, south of Italy, He informed that its air traffic was still altered. Click on the image to go to Tweet. A coveted show. The eruption of the Etna volcano can be overwhelming, but also leaves a Fascinating show in which snow and lava are combined. And as such it has not taken the interest of hikers who have approached the mountain to enjoy the landscape. It He reported yesterday ANSA, the main Italian news agency, which already presents Etna directly as the “new focus of encompassing” For a long time Italy. A tide of hikers. The agency speaks that about a thousand hikers have come to contemplate how it manages the lava from the crater of Bocca Nuova and media like Euronews either The Guardian They go further by pointing out the presence of “Miles” of curious who have approached Mount Sicilian to see the show in situ. Your presence can also be found in networks, with Videos and images of people approaching or even skiing near the lava river. The Italian Marco Bassot shared For example on Instagram a video in which it can apparently be seen sliding with a snowboard table next to the message “The craziest race of my whole life.” Civil Protection has already asked hikers to extreme caution and comply with the standards and remember that a minimum distance in front of the lava of Between 300 and 500 m. @accuweather WHERE LLAND MEETS SNOW 🌋❄️ SKIERS AND HUKERS WERE SPOTTED GETTING A CLOSE-UP View of Lavator and ROCKS SPURTING OUT FROM MOUT ETNA ONTO THE SNOW. #lava #Volcano #Fireandice #Mountetna #itly #mtetna #cool #Skiing #winter #Snow #News #accuweather ♬ Original Sound – Accuweather “Extremely dangerous”. The Regional Manager of Civil Protection, except cook “Of cars. Sunday warned On Facebook: “As night falls, the situation becomes extremely dangerous, with growing risks of falls and sinking in snow.” “I have seen many photos and videos of people who approach dangerously to the front, even skiing,” Recognize Carlo Caputomayor of neighboring BelPasso, to The Guardian. “Although it is visually shocking, it exposes them to serious risks, since it washes it, when it comes into contact with the snow, it can vaporize it instantly and, with the energy released, it can violently launch fragments or rocks.” A touch of attention. Visitors and curious are not the only ones who risk. ANSA He pointed out yesterday that the presence of hundreds of people attracted to the rash show was “blocking” the streets, which is an added risk. The reason? Kitchen points That people park their vehicles along narrow roads and prevent passing through Vetor, “making it impossible to pass rescue vehicles.” He has already warned local authorities. The Italian agency Precise that on Sunday Civil Protection came to mobilize even four units of Belassso, Ragalna, Nicolosi and Adrano to support the population and prevent tourists and hikers from arriving from sicily or other nearby points complicated traffic in the area, with the risk that It supposes. Click on the image to go to Tweet. “Combine” enjoy safely. Kitchen Recognize That many of the curious who come to the mountain are well equipped and in the company of guides or volcanologists, but warns of the risk of cars saturation and the block of the same streets through which emergency vehicles circulate. The key, he insists, is to “combine” the enjoyment of the volcano with security. “Yesterday afternoon there was a constant influx of one thousand people from Provincial Highway 92 and the Milia road, wild parking at the edges of narrow streets, traffic lock in Vetor piano and impossibility of passing emergency vehicles,” He insisted kitchen in Your message.

Although experts see no signs of an eruption, they insist that it must be monitored closely.

by

Over the past few years, and especially this past week, Teide has been attracting the attention of experts and locals alike. The reason is that this dormant giant has been showing signs of activity for a few years. Activity, which, these same experts point out, should not lead us to think that an eruption could be near. “Anomalous” activity. The scientific team in charge of monitoring the state of Teide has detected some “slight” changes to this one. This is an increase in carbon dioxide (CO2) emissions and a deformation of the land. The information emerged after the meeting last week of the scientific committee of the special civil protection plan for volcanic risk in the Canary Islands (Pevolca). No risk in the short or medium term. The team emphasize that this does not imply an imminent eruption, not even close. For this reason, they clarify, it is not necessary to move to the yellow seismological risk alert level. “It is important that people understand that this is not the situation we experienced on La Palma before the eruption,” explained Itahiza Domínguez, director of the National Geographic Institute (IGN) in the Canary Islands, in statements collected by the agency EFE. Precursors. For now, Teide has not given the type of signs of activity that could be linked to the arrival of an eruption. As explained by the IGN itself, basaltic-type eruptions such as the one that would be expected in this volcano are preceded by “very strong” precursors of seismicity: the deformations of the terrain and the emission of gases would be accompanied by intense earthquakes and swarms. “very dense” of seismic activity. Domínguez recalls that the island of Tenerife is “volcanically active”, which implies that an eruption is possible at some point in the future, but we still do not have any signal that tells us when it could occur. Since 2016. The observed rebound in the island’s geological activity it’s not entirely new. Starting in 2016, the experts who monitor this activity began to observe an increase in the volume of CO2 expelled by Teide accompanied by an increase in the microseismicity of the environment. Nemesio Pérez, director of the Canary Islands Volcanological Institute (Involcan), spoke of “significant changes” that have occurred in the last eight years. Clarify, however, that this does not mean that they are changes towards an eruption.” More surveillance. Last week’s meeting served to emphasize the need to reinforce surveillance of the volcano under the highest peak of the Canary archipelago (and the rest of the country). “We do not see a magma movement per se, but we must monitor it,” Domínguez pointed out to EFE.
