Unveiling the Explosive Secrets of Dormant Volcanoes

Researchers studying the Ciomadul volcano have uncovered valuable insights into the reactivation and eruption forecasting of long-dormant volcanoes. By analyzing the chemical and mineral composition of the magma, they discovered that even after tens of thousands of years of dormancy, a volcano can rapidly become active and pose a previously unknown threat. The study highlights the importance of understanding the signs before a volcano erupts and the potential dangers of inactive volcanoes.

Using Lasers to Predict Volcanic Eruptions

Researchers have developed a new method using laser technology to analyze the chemical composition of erupted magma from volcanoes. By isolating the melt signal and analyzing it with mass spectrometry, this method provides a faster and more detailed measure of melt chemistry and its evolution over time. The study focused on the 2021 eruption at La Palma in the Canary Islands and found variations in lava chemistry linked to changes in earthquakes, sulfur dioxide emissions, eruption style, and hazards. This method could help improve monitoring and forecasting of volcanic eruptions, providing valuable insights into why they start and when they will end.
