The team warns that climate change may be going to wake hundreds of inactive volcanoes around the world, which can release destructive disasters.
Thanks to a thorough study of six volcanoes in the south of Chile, including the current Machvino volcano, the researchers came to the conclusion that huge ice rivers play a decisive role in the softening of volcanoes for millennia.
Dr. Pablo Moreno-Yarger, one of the leaders of the research group, explains this phenomenon, saying: “When the thick layers of ice over the volcanoes accumulate, its huge weight works to put pressure on magma in the depths, which limits its revolution.” But the image radically changes with the melting of these ice rivers, since this pressure gradually disappears, allowing jewelry gases in expansion and prepares circumstances for more violent and repeated revolutions.
An accurate analysis of volcanic crystals and methods of historical history revealed an exciting style: during the last ice age (from 26,000 to 18,000 years), a thick ice cover in Patagonia helped to restrain volcanic activity, while a quick phase of melting, which followed in a series of violent revolutions.
Today, this scenario is repeated in several regions around the world. In Antarctica, where the frequency of melting ice is accelerated, as well as in other regions, such as Alaska, New Zealand and Siberia, we can be on the verge of a new era of escalation of volcanic activity.
But the consequences are not limited to the direct risks of volcanic revolutions. As Dr. Moreno-Jagger explains, complex climatic effects arise that arise as a result of this phenomenon. In the short term, volcanoes can distinguish a huge number of particles stuck in the atmosphere that reflects sunlight, which leads to temporary cooling. But with the repetition of revolutions, greenhouse gases accumulate in the atmosphere, which can contribute to the exacerbation of the phenomenon of global warming in the long term.
These results, which were presented at GoldShdett conference in Prague, open the door for urgent questions: are we entering the new era of climatic Volkan reactions? How can humanity prepare for a clash with these double problems?
It seems that the answers will require a greater study and the exact monitoring of these “sleeping giants”, some of which may wake up in the near future from climate changes made by the people themselves.
