Abstract

In this paper we treat two important aspects concerning the automatic monitoring of the ground deformation at the Sciara del Fuoco (SdF), the Stromboli volcano (Italy) steep flank subjects to dangerous landslide events: the developments of suitable software procedures to process observations and the evaluation of both 3D motion maps and 3D strain tensor over the whole investigated area. Ground deformation measured by the monitoring system known as THEODOROS (THEOdolite and Distancemeter Robot Observatory of Stromboli) is often affected by offsets and spikes, due to both malfunctioning and periodical maintenances of the system, and other noise sources making very difficult the interpretation of the ground deformation dynamics. To this purpose a suitable software tool able to reduce these drawbacks was developed. Furthermore, both 3D motion maps and 3D strain tensor are computed in order to provide new useful information aimed to better understanding the complex dynamic of the SdF.
