Gas surveys reveal spatio-temporal changes in gas composition and fumarolic activity at La Fossa, suggesting volcanic unrest may have peaked in late 2021.
Key Points
Gas composition shows significant variation, with fumaroles indicating changes related to volcanic unrest.
Gas surveys employed a Multi-GAS instrument for spatial mapping of emissions during 2021-2024.
Findings highlight the role of magmatic and hydrothermal processes affecting volcanic gas emissions.
Data from infrared thermal imaging correlate with sulfur dioxide flux, supporting volcanic activity assessments.
