monitor disasters in real time

There are natural disasters such as strong storms that cause floods, maritime storms or uncontrolled fires in which observing the evolution is providential both when it comes to sizing the mishap and to draw up a strategy for solutions on the ground. In this scenario, satellites are real lifesavers. So Spain and Portugal are going to launch a “atlantic constellation” of satellites that observe the Iberian Peninsula from space to protect it. The context. It is not difficult to find catastrophes that have hit the peninsula in recent years, as an example is the train of storms with which we began 2026 and whose effect can be seen from space or the DANA that destroyed Valencia. Currently, the reference satellites for forest management, fires and emergencies in Europe are ESA’s Copernicus / Sentinel, which generate images of the Iberian Peninsula every two or three days. What is the Atlantic Constellation. It is a set of 16 small satellites, eight launched by each country, which will orbit less than 700 kilometers from Earth, coordinating to generate images of the territory every two or three hours. It is a complement and not a replacement for the European Copernicus Sentinel. Why is it important. The implementation of the Atlantic Constellation brings an obvious improvement when it comes to evaluating progress and planning solutions to disasters: going from having information every 2 – 3 days to doing it every 2 – 3 hours, practically in real time for this type of disasters. On the other hand and as explained for El Periódico Nicolás Martín, director of Users, Services and Applications of the Spanish Space Agency, this is a project “very relevant for the Spanish aerospace sector and for our strategic autonomy.” And although its main mission is emergencies and natural disasters, it also has applications for other sectors and entities, such as agriculture. How are they going to do it? Spain has awarded their part to the Catalan Open Cosmos through a contest. The company will be in charge of designing and manufacturing the state’s eight satellites, while the ICE-CSIC will develop one of the four payloads of each satellite and the geophysical data extraction algorithms. On the Portugal side, it will be GeoSat who leads the project. The ESA will be the one who supervises everything. On each satellite there will be four instruments: high-resolution multispectral optical cameras to analyze vegetation and terrain, GNSS reflectometry sensors to measure soil moisture or sea state, IoT connectivity and a system to identify and track vessels. The roadmap. The first demonstration satellite will be called Pathfinder and according to the project schedule, it will be ready by the end of this year. It will be launched in the first half of 2027, thus serving to validate the integrated technologies before manufacturing the rest of the units. However, the full deployment of the entire satellite fleet will take place in the following years.

A geologist explains why natural disasters continue to surprise us

How can an eruption on the other side of the planet cause a “year without a summer”? Why does an apparently small earthquake devastate a city while a larger one goes almost unnoticed? The answer is not always in magnitude of the phenomenon, but in the place where it occurs, in the number of people exposed and in how the risk is managed. Understanding it is not just a scientific question: it is a way of looking at the planet with different eyes. ‘Science and aside’ It is the space where we talk about science with experts. It is part of our YouTube channel and is also available as a podcast on Spotify and iVoox. In her fourth episode, Ángela Blanco interviews Rosa María Mateosgeologist and director of the Geological and Mining Institute of Spain (IGME-CSIC), a reference voice in the study of natural disasters. With decades of experience and a doctorate focused on this field, his vision helps us understand what is happening on Earth. When science faces the fury of the planet The conversation starts with a seemingly simple question: what is the most damaging natural disaster? The interviewee responds calmly: “It depends where you are and where you live.“In his explanation there are no hierarchies between volcanoes, earthquakes or tsunamis, but nuances. “Living in the Canary Islands, which has a high probability of a volcanic eruption, is not the same as living in Madrid, where the probability is zero.” The danger changes with the map, and understanding it requires looking at the geology of each place before its history. “Among the great episodes that marked the history of the Earth, Rosa cites one that was on the verge of erasing our species from the map. “We are talking about 74,000 years ago, which probably was on the verge of ending the Homo sapienswith our species.” It refers to the eruption of the Toba volcano, a megaeruption in Indonesia. Rosa explains that not all earthquakes are measured the same and that their magnitude can be misleading if you do not understand how it is calculated. “The magnitude of the earthquakes It is measured on a logarithmic scaleto. This means that an earthquake of magnitude four is not twice as strong as one of magnitude two.” The difference, he clarifies, is exponential: each point on the scale multiplies the energy released, and that is enough to turn an earthquake into a colossal force. Some historical episodes demonstrate this better than any graph. Rosa remembers the Lisbon earthquake of 1755 not only for its magnitude, but for what it represented for science. “The waves reached the coasts of Finland.” The phrase summarizes the scope of a phenomenon that destroyed the Portuguese capital and left traces throughout the Atlantic. From that disaster a different way of thinking was born. To understand why some catastrophes are devastating and others are barely mentioned, the expert introduces an essential distinction. “We geologists talk about two very different concepts that we often confuse. One is the danger… and another thing is the risk.“In the video he explains what each one consists of, their scope and also the consequences of confusing the terms. The conversation with Rosa María Mateos shows that natural phenomena cannot be avoided, but their effects can be reduced. In this episode of Science and apartthe geologist explains how observation and knowledge help to anticipate risks and live better with them. A talk that leaves open the door to continue learning about the planet we inhabit.

The devastating economic consequences of natural disasters in the United States in 2024

Last year, devastating natural disasters in the United States according to Aon PLR insurance broker increased economic losses to approximately $ 217.8 billion. The figures registered by the insurer represent an increase of more than 85% compared to 2023. In this regard, Liz Henderson, global director of advice on Aon climatic risks commented that “when natural disasters occur and affect extensive areas and areas with great value in terms of propertiespeople and content, the losses derived from these phenomena are usually significantly greater, ”said CBS. Through a report, Aon explained that, during 2024, The economic losses that cover insurance increased to $ 112.7 billionthat represents 36% more compared to 2022 the highest figure recorded so far. Only Hurricane Helene caused economic losses close to $ 75,000 million, while Milton losses were approximately $ 25,000 million. However, The agency for the beginning of this 2025 continued to count the losses with the unfortunate forest fires in Los Angeles Countythat until times caused the destruction of 14,000 structures, this according to the experts could become one of the most expensive natural disasters for the State and the country, the figure it will represent for insurers cannot be calculated exactly.
