The morphologies of volcanic active areas are the surface expression of several volcanic processes, and the accurate digital reconstruction of such morphologies has received great attention over the past years due to the importance of such data. A detailed digital elevation model is in fact fundamental for modelling several volcanic phenomena such as lava flows, pyroclastic flows, lahars, tephra fall-out deposition and ballistic impacts. In addition, in case of high magnitude eruptions affecting highly populated and urbanized areas, an accurate reconstruction of the topography becomes an essential tool for volcanic hazard and risk assessment.This session welcomes contributions that use Geomatics disciplines such as Airborne and Terrestrial LIDAR, Aerial and Satellite Stereo Photogrammetry by using Multispectral Optical and IR data, Synthetic Aperture Radar and Photogrammetry by drones, to obtain volcanic topographies used as input data for modelling the investigated phenomena or mapping the volcanic hazard. New ideas, developments and applications are welcome.
