Signs of a volcanic eruption in ice sheets 2022 news . Scientists are studying the history of 60,000 years in the layers of ice where they have found traces of thousands of volcanic eruptions. Of these, 25 are volcanic eruptions that the Earth has never seen in more than 2,500 years.

Researchers excavated layers near the two poles. Antarctica (where 737 volcanoes erupted) and Greenland (where traces of 1113 volcanoes were found). In all, 85 volcanoes were so large that evidence of them was small at both poles.

This evidence of volcanic eruptions took the form of sulfuric acid deposits. This gave researchers an indication of how powerful those particular volcanoes would be.

Anders Swenson, a physicist at the University of Copenhagen in Denmark, says that ice sheets are more useful than other methods in rebuilding ancient volcanoes.

He added that whenever a large-scale volcano erupts, sulfuric acid is released into the upper atmosphere, which then spreads around the world, including in Greenland and Antarctica.
“Looking at the amount of sulfuric acid falling, we can estimate the eruption,” he said.
