TL;DR: In this article, a 3D time-lapse resistivity imaging on an active landslide was used to provide long-term data highlighting the evolution of moisture content prior to landslide reactivation and showing its decline post reactivation.

UAV monitoring and documentation of a large landslide
TL;DR: In this paper, a bundle of technologies was applied to monitor and document the landslide, such as geophysical methods (geoelectrics, inclinometer, soil moisture, and soil temperature) and Global Navigation Satellite System (GNSS) measurements.

A Review of the Advantages and Limitations of Geophysical Investigations in Landslide Studies
TL;DR: In this paper, the authors focused on works of the last twelve years (2007-2018), and the main goal is to analyse the geophysical community efforts toward overcoming the geophysics and landslide review highlighted in the 2007 geophysicists and landslides review.

TL;DR: In this article, a 3D electrical resistivity (3D ERT) was used to identify the steepest gradient in first-derivative resistivity profiles, which yields an estimate of bedrock depth (verified by drilling) to a precision better than 0.2m.

Evolution of soil wetting patterns preceding a hydrologically induced landslide inferred from electrical resistivity survey and point measurements of volumetric water content and pore water pressure

TL;DR: In this article, electrical resistivity tomography (ERT) was used to monitor the hydrological state of a hillside prior to a sprinkling-induced shallow landslide, and the results indicate that when large and interconnected regions of hillslope are saturated (as confirmed by high volumetric water content and low standard deviation of water saturation), additional water cannot be redistributed to empty drier regions and may eventually enhance local pore water pressure and seepage force, initiating large shear deformation and failure.
