  • Statistical analysis of dispersal and deposition patterns of volcanic emissions from Mt. Sakurajima, Japan

    Poulidis Alexandros P. , Takemi Tetsuya , Shimizu Atsushi , Iguchi Masato , Jenkins Susanna F.

    … Mt. Sakurajima (Japan) provides us with a rare opportunity to study such activity, due to its eruptive behaviour and dense observation network. … Climatological and topographic effects are suspected to impact the deposition of volcanic ash away from the vent: for sampling stations located close to complex topographical elements, sharp changes in the deposition patterns were observed, with ash deposits for neighbouring stations as close as 5 km differing as much as an order of magnitude. …
