An attempt to establish a new methodical basis for better insight into the process of gravitational failure of slope rock mass as it demonstrate itself by deformation events in time. To improve an information gain, new tools are searched by examination of application possibilities of non-linear dynamics. New ways of processing and interpretation of primary, empirical data - predominantly already archived, are be aimed to gain new information. The information wanted is believed to be still hidden within the primary data – the complexly structured time-series of rock slope monitoring, because it seem to be only a signal noise to our common methods. Therefore, the use of non-linear time-series analyse is stressed. The results obtained are used to check and improve the applicant’s phenomenological model of development of slope movement activity in the course of a rock fall preparation and also to set general methodical limits for assessment of an actual instability degree for the slope in question and to make time prognoses of the instability development.
