The world is “woefully ill-prepared” for a massive volcanic eruption. This is the conclusion reached by volcanologists from the University of Cambridge, Michael Cassidy and Lara Maní, in a study carried out jointly with experts from the University of Birmingham and which was published in the scientific journal ‘Nature’. These experts spoke about the investment made by governments in recent years to monitor and respond to possible volcanic catastrophes. “There is no coordinated action, nor large-scale investment, to mitigate the global effects of large-scale eruptions. This must change.”, the study authors argued. They also argued that there is a “widespread misconception” that the risks of a massive eruption are low. On the other hand, the effects of this large volcanic eruption would have a huge impact not only on the climate, but also on supply chains. and in global trade, with the consequent increased risk of famine and economic loss. “Impacts would cascade across transportation, food, water, trade, energy, finance and communications because it is a globally connected world.” A number of conclusions they have reached after Last year, researchers analyzed ice cores in both Greenland and Antarctica. As many as 1,113 eruption signatures have been recorded in the ice at the North Pole and 737 at the South Pole, which formed between 60,000 and 9,000 years ago. Of all of them, 97 events probably had a climatic impact equivalent to that of an eruption of magnitude 7 or greater. The researchers concluded that magnitude 7 events occur approximately once every 625 years. As an example, they gave the case of the Hunga-Tonga volcano eruption that occurred in January of this year and caused the almost complete disappearance of by the tsunami caused by a powerful underwater volcanic eruption in the Pacific. More than 20 ships capsized off the coast of Japan because of the tsunami caused by the eruption of the underwater volcano that erupted near the Tonga archipelago. “It was the volcanic equivalent of an asteroid that ‘almost collided’ buzzing near Earth,” they mention the authors of the study in the aforementioned scientific journal, who also explained the effects that the eruption had in other places on the planet. “Underwater cables were cut, cutting off Tonga’s communications with the outside world. The explosion created a global shock wave and tsunamis that reached the Japanese and American coasts.”“The regions of greatest vulnerability must be identified”Mani and Cassidy called on government authorities and the main international organizations for the identification of volcanoes potentially active and conducting an analysis of the historical and geological records. “The regions of greatest vulnerability and exposure to volcanic threats must be identified.” Finally, the volcanologists recalled that planetary defense “receives hundreds of millions of dollars of funding each year and has several world agencies dedicated to it,” as well like the last great eruption that happened in 1815 in Indonesia, in which approximately 100,000 people died and which caused an average drop in global temperatures of one degree.
