4-4-4-4-4-4-4-4-4-4-4-4-4 From: William Chadwick <william.w.chadwick@xxxxxxxxx> *Special Issue: Volcanic processes: tectonics, deformation, geodesy, unrest* Dear colleagues, We cordially invite you to contribute research articles or review articles for consideration and possible publication in a Special Issue of the Bulletin of Volcanology on: â??Volcanic Processes: Tectonics, Deformation, Geodesy, Unrestâ??, which deals with the documentation and modelling of the tectonic, deformation and geodetic features of any type of volcanic area, on land and/or offshore. The focus is on advancing our understanding of any type of deformation of active or non-active volcanoes, on the associated behaviors, and the implications for hazards. We welcome contributions based on results from fieldwork, remote-sensing studies, geodetic and geophysical measurements, oceanographic studies, analytical, analogue and numerical simulations, and laboratory studies of volcanic rocks. Studies may be focused at the regional scale, investigating the tectonic setting responsible for and controlling volcanic activity, both along divergent and convergent plate boundaries, as well in intraplate settings. At a more local scale, all types of surface deformation in volcanic areas are of interest, such as elastic inflation and deflation, or inelastic processes, including caldera and flank collapses. Deeper, sub-volcanic deformation studies, concerning the emplacement of intrusions, as sills, dikes and laccoliths, are most welcome. We also particularly welcome geophysical data aimed at understanding magmatic processes during volcano unrest, on land and offshore. These include geodetic studies obtained through GPS InSAR, or other ocean bottom methods, as well as the modelling of deformation sources.
