Mud volcanoes are mud emissions generated by the rising gas from deep hydrocarbon deposits. The extruded material is mainly composed of methane, fossil salt water and clays, and results deposited on the ground forming cones and pools. The Salse di Nirano reserve is one of the oldest and ancient example of geological protected area, in Italy and in Europe. In this technical report it is widely described the terrestrial laser scanning (TLS) measurement campaign performed on February 2020 together with results and considerations/opportunities for planning an exhaustive monitoring of the area. The research aims at providing a reliable contribute in searching for possible correlations between areas movements and mud extrusions. In summary, this paper shows the first TLS observation carried out to start the monitoring of the studied phenomena.
