One of the most important aspects of early warning systems and risk reduction techniques is early detection of events such as landslides or subsidence is ground displacement monitoring. Landslide is considered as one of the most dangerous natural disaster which occurs mainly in hilly areas. There are already many types of instrumentation, but those capable of delivering real-time alerts on multiple time series are usually based on expensive hardware, illustrating the need to develop a low-cost, easy-to-install device suitable for emergency surveillance. Consequently, a wireless network based on ultra-wideband radiofrequency impulse technology was realized. This network's uniqueness is its ability to determine the distance between nodes using the same signals that are used for transmission without the need for an actual measuring sensor. The system was tested in Central Italy by tracking a mudflow, and revealed its suitability as an early warning device. Further work on potential low-cost hardware integration and eventual industrialization will boost this promising technology further.
