Ash clouds emitted during the eruption of an Antarctic volcano may disrupt air traffic in the southern hemisphere, according to a study made by researchers from the Institute of Earth Sciences Jaume Almera of the CSIC (ICTJA-CSIC) and the Barcelona Supercomputing Center (BSC). The authors have analyzed for the first time the effects and dispersion patterns of ash clouds released during a hypothetical eruption of the Deception Island volcano, which would have the potential to reach tropical latitudes. The research, published in Scientific Reports journal, demonstrated that Antarctic volcanoes may pose a greater threat than previously believed.
