Tenerife has recorded more than 1,600 earthquakes in two days. Volcano experts keep saying the same thing: tranquility

During the night of Wednesday, July 22, to Thursday, July 23, Tenerife trembled due to the effect of hundreds of small earthquakes. In a few hours, the automatic detectors captured more than 500 earthquakes, although manually, under review by seismologists, the figure was reduced to 100. In total, since then, around 1,500 very low magnitude earthquakes have been reported, many of them hybrid. This means that they are produced both by the breakdown of rock and by the underground movement of fluids. In volcanic territories, such as Tenerife, this is especially worrying, since this fluid could be the magma of a volcano awakening from its slumber. Even so, experts call for calm. Earthquake swarms They are normal in these areas and would have to be more intense to really represent the preamble to an eruption. It is something that, according to what they say from The Countryalready happened in 2004, but even then it turned out to be a false alarm. 750 small earthquakes. The majority of earthquakes in this swarm of Tenerife earthquakes have a magnitude of between 1 and 2. This is a very low intensity to cause concern to the population. Although there were some before and have continued to happen after, most of these tremors took place between 2 and 5 in the morning, at depths of 10 to 15 kilometers. Yes, it could be due to the movement of magma, as has happened with other recent swarms. Since February, about 10 similar episodes have been recorded. In all cases they have been hybrid earthquakes, but of low magnitude. Some have been slightly more intense than these and still nothing has happened. That is the reason why there is a call for calm. Active, inactive or extinct. A volcano is considered active when it has erupted on recent geological scales. Normally 10,000 years are used as a reference figure, although it may vary depending on the source. An example is Mount Etna in Italy.. Dormant volcanoes are those that have not erupted for many thousands of years, but still have the potential to do so, as there is still a source of magma available. This is the case of the Mount Omuro volcano, in Japan. Finally, extinct volcanoes are those that can no longer erupt, because they have lost connection with their magma source, which may have diverted, solidified, or disappeared completely. In Spain, the Cabo de Gata volcanoes in Almería are in this state. In the case of the volcanoes of Tenerifeare considered active, since it has been just over a century since their last eruption. Even so, that does not mean that there will be another one imminently. The latest eruptions. There have been no eruptions in Tenerife since November 1909, when the Chinyero eruption. This was preceded by intense seismic activity, which began in March 1908, more than a year earlier. However, they were much more intense tremors than those happening now. There was even a strong emission of fumaroles in the Teide crater. Other sources suggest that the tremors began a little later, but in any case more than 6 months before the eruption and always of great intensity. It is true that, since they occurred so long ago, there is no record of the magnitude of those earthquakes. However, there are many testimonies from neighbors who felt them, while those that are happening in Tenerife now are of such a low magnitude that it is very difficult for the population to notice them. Magma on the surface. In addition to fumaroles, the movement of magma on the surface is one of the signs that a volcanic eruption is close. It is another reason why geologists insist that this seismic swarm does not predict an eruption in the short or medium term. With the earthquakes of 2004 there was more concern, because yes they were felt by the populationalthough they did not have a magnitude either very high. In addition, magma was detected very close to the surface. Even so, the systems for detecting and monitoring earthquakes and possible volcanic eruptions were not as good as those today. Today the preambles of a volcano eruption are much better known and, with what is currently happening, there is nothing to fear.

Tenerife was known for the sun and its beaches. It will soon house one of the five most powerful supercomputers in Spain

Tenerife will have a new supercomputer. I already had two with the names of Teide and of Anagaand they will now be joined by a new and promising project called the Atlantic Supercomputing Center. With it, it is hoped to turn the Canary Islands into a new nerve center for retaining and attracting talent in the technological field. Up to 10 million euros of investment. This new project It is a collaboration of the Cabildo of Tenerife and the Institute of Technology and Renewable Energies (ITER) with the German technology giant Bechtle. It will have an initial investment of 5.5 million euros, which could rise to 10 million as its four phases are deployed (two for storage, two for computing) oriented by the demand for the center and its resources. The expansion is flexible and Bechtle will supply the latest technology available at the time of project execution to avoid the use of obsolete components. The fifth supercomputer by power in Spain. By integrating with the existing nodes, the Atlantic Supercomputing Center will achieve a combined power that will place it as the fifth most powerful supercomputer in the entire national territory. It is also expected to enter the prestigious TOP500 list which brings together the most powerful supercomputers from around the world. Hybrid architecture. The rise of AI has meant that the project has an architecture that will allow working with both more conventional workloads and those intended for projects in the field of artificial intelligence. Thus, its architecture will be hybrid: CPU: although it has not been specified which processors it will use, it has been indicated that the supercomputer will have 13 nodes with 288 cores each, which will allow for more than 3,000 process cores to execute scientific tasks, for example. GPU: there will also be four specialized nodes with a total of 32 Nvidia H200 NVL cards, which will allow training of large language models and the development of AI projects. Performance: this expansion is expected to provide between 1.3 and 1.4 PFLOPS of global computing power (close to 300 TFLOPS in CPU and almost one PFLOP in GPU), indicated those responsible for the Cabildo de Tenerife and ITER. Hours instead of months. The president of the Cabildo, Rosa Dávila, stood out that local laboratories, the University of Las Palmas de Gran Canaria and the University of La Laguna among others will be able to access these resources to be able to compute in hours what previously could take months. Juan José Martínez, from ITER, recalled how during the pandemic the Teide-HPC supercomputer It was one of the five centers in all of Spain who sequenced and monitored the biological variants of COVID-19. From the audiovisual sector to the aerospace sector. Among the sectors that will benefit from this computing capacity will be those associated with the audiovisual industry. The Teide-HPC infrastructure was for example used to render scenes from the film ‘Tadeo Jones 2: The Secret of King Midas‘. It will also be the core of the project management of canary satellite constellation. Attracting talent. This facility also wants to become an element that reinforces the role of the Canary Islands as a technological hub. Having a supercomputing infrastructure like this wants to help attract technology companies that promote highly qualified young employment and therefore retain and attract new talent in this sector. Efficiency. Although the power of Teide HPC will greatly benefit from these new resources, advances in photolithography will mean that the new supercomputer will occupy only a quarter of the previous physical space. Its environmental impact will also be zero: the infrastructure will be located in ITER’s own facilities, and will be powered entirely with clean energy from its wind farms and photovoltaic plants.

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

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.

The day that United Kingdom invaded Tenerife without knowing what was inside

Almost all the nations of the old continent have a historical figure in war. However, few as the figure of the vice courage HORATIO NELSONOfficer of the British Royal Navy (Royal Navy) whose name became omnipresent during the contests of the French Revolution and the Napoleonic Wars. To get an idea, it is considered one of the greatest naval commanders in history. Everything changed when it arrived in the Canary Islands. He fled. And without an arm. Context: Cádiz and British frustration. To understand how the plan to take the island of Tenerife began we must go back to The Battle of Cabo San Vicente In February 1797. It was a British victory over the Spanish Navy, but failed to completely weaken the enemy fleet. In fact, the Admiral John Jervisfrustrated by The resistance in Cádiz And the difficulties in maintaining an effective block, decided to divert his attention to the south. Destination: Tenerife, a key point on Spanish trade routes with America. Plus: The report that several Spanish ships They transported wealth from the American continent Towards the island he convinced Jervis that a surprise attack on the capital of Santa Cruz could result in an easy victory. Thus, he called and ordered Horathio Nelson to command an expedition with the aim of taking the city and looting his treasures. The game. Nelson’s historical figure entrusted to the mission. The commander left on July 14, 1797 with a powerful squad of 4,000 men and more than 400 cannonscomposed of its HMS toheus flagship and other vessels such as the HMS Culloden, HMS Zealous next to several frigates and auxiliary ships. The plan consisted of a night operation with landing at two strategic pointsfollowed by a final assault against the port. Defensive preparations. It happens that the general lieutenant Antonio Gutiérrez de Otero and Santayanawho had already defeated the British in two previous attempts, anticipated the attack and Fortified Santa Cruz With 91 artillery batteries, regular troops, local militiamen and French sailors captured from the Mutine frigate. Although his strength was less, With 1,700 menthe fortified position of the city gave him a decisive advantage. Nelson portrait The British attack. On July 20, Nelson sent an ultimatum demanding the surrender of the city and threatening its destruction if their demands were not met. Gutiérrez categorically rejected the proposal. Thus, in The night of July 22the British attack began with a first wave of landing on the beach of Valseco, but the strong currents and Spanish fire caused confusion among the attackers. Several boats sank, and the soldiers who managed to reach the ground were easy white for Spanish artillery. Seeing the failure, Nelson ordered the withdrawal of this first incursion. Determined to take Santa Cruz, Nelson devised A second assaultthis time led by himself. At 10:30 pm on July 24, he directed A flotilla of 700 men towards the port with the hope of surprising the defenders. However, the Spanish sentries detected the maneuver and gave the alarm. At 11:00 pm, an intense rain of cannon shots and musket shot fell on the British, who met their wet and unused ammunition. The arm. Here is one of the most notable facts of the battle due to the importance of the character. Nelson, who had just landed on the beach, was reached by A cannon shot In the right arm. Seriously injured, his stepson, Lieutenant Nisbet, made an improvised tourniquet and took him back to HMS tohels. Once on board, the surgeon He amputated his arm and the remains were thrown into the sea. Nelson, frustrated and weakened, was removed from combat. Canarian resistance. Meanwhile, the British who managed to disembark on the beach of the butchers tried to take the city, capturing the convent of the consolation. What happened? Who were surrounded and harassed by Cross fire from strengths And the roofs of the houses, where citizens joined the defense shooting at the invaders. The British managed to momentarily block access to the port, but without support from the sea and with many casualties, they realized that they were trapped. Toubridge, the British commander in command after the withdrawal of Nelson, threatened to set the entire city on fire if they were not allowed to retire with honor. Gutiérrez, experienced military, refused to give in to intimidation and increased bombing About the besieged British. The surrender. In the early hours of July 25, seeing that there was no escape, Toubridge requested a truce. Gutierrez, in a gesture that historians have always defined as of gentlemenityhe agreed to negotiate and allowed the British to retire with military honors, on condition that they did not attack Tenerife or the Canary Islands. The final figures threw a clear winner: the Spaniards lost only 30 men, while The British suffered 250 dead and 128 injured. Gutiérrez even lent ships to the British to transport their wounded soldiers back to England. Beer and cheese. In fact, in an unusual courtesy exchange in times of war, Nelson sent a letter of thanks to Gutiérrez, apparently accompanied by English beer and cheese. Gutiérrez replied by sending him Spanish wine and cheese. Despite the friendly gesture, Nelson never forgot that humiliation suffered in Tenerife, a battle that later I would describe how “The most horrible hell I’ve ever endured.” Impact and legacy. This was folded to a story that could have changed the Canary Islands flag. The Defeat in Santa Cruz de Tenerife It marked the end of British ambitions in the islands. The Royal Navy never tried to invade Tenerife, and the victory strengthened Spanish morality at a crucial moment of the United Kingdom. Since then, in Santa Cruz the battle is commemorated every year The recreation of the deed of July 25, in which actors dressed in replicas of the uniforms of the time recreate the confrontation. With a lower army in number and resources, Gutiérrez and his troops showed that strategic resistance and knowledge of the land could even impose himself on the most … Read more
