Improving Landslide Displacement Measurement through Automatic Recording and Statistical Analysis

This short paper illustrates some theoretical aspects concerning the accuracy and reliability of continuous measurements of underground slope displacements. The Modular Underground Monitoring System (further referred as MUMS), is an automated monitoring system which collects and remotely sends data, it does not require the presence of a field operator and it was designed to have a lifetime longer than that of traditional inclinometers. We present the results of some early generation MUMS to highlight different problems in the analysis of collected data. Finally, the results obtained by a new installation are shown to highlight the achieved progresses.
