..The Broadband Acquisition and Imaging Operation (BAcIO) is an ‘operative’ workshop that will take place at Stromboli Island (Italy) from 20 to 27 may 2023. This edition is part of the Departmental strategic project UNO: UNderstanding the Ordinary to forecast the extraordinary: An integrated approach for studying and interpreting the explosive activity at Stromboli volcano.
It is conceived as a multidisciplinary ‘hands-on’ field experiment and is meant to gather specialists or apprentices in the use of field-based techniques for volcano monitoring/observations of persistent explosive activity.
Started in 2012 as an INGV-LMU research collaboration, and formalised as BAcIO in 2014, the initiative has been carried out every year successfully involving a growing team of international researchers/technicians with expertise in various fields of volcanology. The aim is to promote the synergic use of different field based measuring techniques, to share expertise, and to expand our knowledge of eruptive processes.
The activity will consist in the temporary deployment of a range of imaging, acoustic, seismic, geochemical and deformation data acquisition systems. Examples of the systems include, but are not limited to, high-speed visible and thermal cameras, seismometers, microphones, UV and SO2 sensors, FTIR spectrometers, gravimeters, tiltmeters, laser scanners and drones.
Observation focus will cover, e.g., eruptive plume dynamics, pyroclast ejection processes extending from the shallow conduit, through their acceleration and interaction with the atmosphere, and their dispersal and deposition, and associated geophysical and geochemical signals.
