Investigating a Large-Scale Creeping Landmass Using Airborne and Subsurface Remote Sensing Techniques

The present paper deals with an inhabited, creeping-mountainous landmass with profound surface deformation that affects the local community. The scope of the paper is to gather surficial and subsurface information in order to understand the parameters of this creeping mass, which is usually affected by several parameters, such as its geometry, subsurface water and rupture zone. Therefore, a combined aerial and surface investigation have been conducted. The aerial investigation involves UAV’s LiDAR acquisition for the terrain model, comparison of historical aerial photographs for land use changes. The surface investigation included resistivity (ERT) and seismic (SRT, MASW) measurements and density determination of geological formations. This combination of methods proved to be fruitful since several aspects of the landslide were clarified, such as water flow paths, the internal geological structure of the creeping mass and its geometrical extent.
