What the Study Found
The study reconstructs the two explosive phases of the eruption, during which plumes of ash and gas reached more than 30 kilometers into the atmosphere. Using numerical modeling and analysis of tephra deposits (materials ejected during the eruption), the researchers provide new insights into the magnitude and dynamics of this event.
Their findings highlight the eruption’s capacity to influence atmospheric conditions and spread volcanic ash over vast areas, which could have had significant climatic and environmental effects at the time.
Why It Matters
Paektu remains an active volcano, making this study relevant for understanding its potential future behavior. By examining past eruptions in detail, scientists can better assess the risks posed by similar explosive events and refine tools for monitoring and response.
A Collaborative Effort
The research brings together expertise in volcanology, geophysics, and atmospheric modeling. Arnau Folch contributed simulations of plume dynamics, while field data and tephra analysis from the broader team provided the groundwork for reconstructing the eruption sequence.
