Ciomadul study reveals rapid and explosive eruptions of long dormant volcanoes

Hungarian scientists studying the Ciomadul volcano have found that even after tens of thousands of years of dormancy, a volcano can rapidly become active and pose a previously unknown threat. By analyzing the mineral composition of volcanic rocks, the researchers identified the conditions and processes that lead to explosive eruptions. They discovered that the presence of distinct amphibole compositions in the magma played a key role in triggering the explosive eruptions. This research highlights the importance of studying long-dormant volcanoes and understanding their potential hazards.
