Landslides are the movement of masses of rock, regolith and soil from high to low places due to the influence of gravitational forces, due to the weakness of the soil structure when saturated. Humidity on a certain slope is an initial indication of a landslide. By using a humidity measuring device you can get a landslide indication value, apart from humidity there is also another indication, namely ground movement which is detected with a strain sensor. Thus, these 2 main parameters are expected to become new findings in the field of landslide disasters as an initial disaster instrumentation system.
