“…Such a layer of weathered zone laid on a bedrock has a great susceptibility to landslide because a slip zone is formed between the weathered zone and the bedrock. Slip planes may be a useful non-invasive method of seismic interferometry [19]. Many scientists have assessed the threat to the infrastructure of landslides including [1,4,6,10,21].…”

A comparative analysis of the results of terrestrial laser scanning and numerical modelling for assessing the stability of a road embankment on the active landslide on the Just mountain at Tęgoborze at Just -Tęgoborze Analiza porównawcza wyników naziemnego skanowania laserowego i modelowania numerycznego dla oceny stateczności nasypu drogowego na aktywnym osuwisku Just -Tęgoborze Abstract This article presents a method for the quick assessment of the safety of the road on an active landslide on the Just mountain at Tęgoborze using the landslide hazard ratio of landslide movements. The hazard indicator for landslide traffic has been defined as the quotient of the largest displacements obtained from measurements using a terrestrial laser scanner to the largest displacement obtained from a numerical model of the worst geotechnical conditions and an unstable landslide. The application of this indicator was presented on the example of national road No. 75 along the section of the road in km from 51 + 900 to 52 + 700 at the location of the Just mountain at Tęgoborze in the south of Poland. The road is located on an active landslide and has a lot of traffic. The measurements were conducted with the RIEGL. VZ400 terrestrial laser scanner from 2012 to 2016. As a result of the measurements performed with a terrestrial laser scanner, a cloud of 3D points was obtained. Differential models of subsequent measurements were constructed and compared to the first base measurements. The results of 3D differential models obtained from terrestrial laser scanner measurements were compared with results obtained from 3D numerical modelling. Numerical calculations were conducted assuming the worst geotechnical conditions. The model of the landslide was fully saturated. A numerical simulation computed using the finite element method (FEM) in the MIDAS GTS program was applied. A result of the safety factor F = 0.8 (i.e. an unstable landslide) was obtained. In order to estimate the hazard, the values of the landslide hazard indicator were determined for each date using the measurements conducted with the laser scanner.

Geophysical monitoring of landslides can provide insights into spatial and temporal variations of subsurface properties associated with slope failure. Recent improvements in equipment, data analysis, and field operations have led to a significant increase in the use of such techniques in monitoring. Geophysical methods complement intrusive approaches, which sample only a very small proportion of the subsurface, and walk-over or remotely sensed data, which principally provide information only at the ground surface. In particular, recent studies show that advances in geophysical instrumentation, data processing, modeling, and interpretation in the context of landslide monitoring are significantly improving the characterization of hillslope hydrology and soil and rock hydrology and strength and their dynamics over time. This review appraises the state of the art of geophysical monitoring, as applied to moisture-induced landslides. Here we focus on technical and practical uses of time-lapse methods in geophysics applied to monitoring moisture-induced landslide. The case studies identified in this review show that several geophysical techniques are currently used in the monitoring of subsurface landslide processes. These geophysical contributions to monitoring and predicting the evolution of landslide processes are currently underrealized. Hence, the further integration of multiple-parametric and geotechnically coupled geophysical monitoring systems has considerable potential. The complementary nature of certain methods to map the distribution of subsurface moisture and elastic moduli will greatly increase the predictive and monitoring capacity of early warning systems in moisture-induced landslide settings.

Abstract.Cases of damage to structures in landslide areas in Poland, and sometimes construction catastrophes, occur most frequently in periods of intense precipitation (e.g. in 1997, 2000, 2002 and 2010). The greatest landslide risk occurs in mountainous areas in the Flysch Carpathians, and the number of landslides posing major problems exceeds 20,000. Terrain surface relief and geological structure including the tectonics, properties of the geological medium, presence of excessive water mostly due to intense precipitation, and human activity have an impact on landslide risk. This paper is aimed at presenting basic principles for the geophysical identification of landslides gained from experience in various regions of Poland, particularly in the flysch formations in the Carpathian Mountains. The geophysical methods which are of the greatest importance in the study of landslides are specified. Their advantages and limitations are presented. The principles of geophysical methods applied at the stage of designing and implementing research, processing and interpreting data, analysis of results, and their documentation are discussed.
