Abstract
The prevention of loss to life and property due to natural calamities is viewed very seriously in many countries of the world. There are many uncertainties in the forecasting of when a movement in a landslide will occur. Acoustic emission (AE) is a natural phenomenon that occurs when a solid subjected to stress experiences non-elastic deformation – fracturing or stick-slip. Acoustic emissions carry information about location, intensity and mechanisms of deformation occurring in a material. The aim of our research is attempt to construct a sensitive acoustic emission registrator. One of the goals of our experiment is optimization of equipment to use them in the field and work for development of a landslides’ acoustic early warning system.
