Fibre-optic distributed acoustic sensing, seismological and infrasonic data set from Etna, Italy

Philippe Jousset, Gilda Currenti, Athena Chalari, Frederik Tilmann & Luciano Zuccarello
Understanding physical processes prior and during eruptions remains challenging, due to uncertainties about subsurface structures and undetected processes within the volcano. Here, the authors use a dedicated fibre-optic cable to obtain strain data and identify volcanic events and image hidden near-surface volcanic structural features at Etna volcano, Italy. In the paper Jousset et al. (2022), we detect and characterize strain signals associated with explosions, and we find evidences for non-linear grain interactions in a scoria...
