Abstract
A commercial drone was used to acquire a series of images in an area in the Venezuelan Andes characterized by the deformation of a regional strike-slip fault. The digital model obtained by processing the images has allowed to obtain quantitative measurements of the fault displacement and to test geological concepts related to the structure evolution. The test has proven several benefits in applying the drone technology to support the classic geological field work.
Highlights
The availability of affordable commercial drones and dedicated software is making it possible to acquire a grid of images over an area and process them to obtain a digital model of the topography
In order to test the benefits of this technology when applied to geology, a drone acquisition was planned in the Venezuelan Andes, in an area where the topography is clearly expressing the deformation induced by active tectonic

Summary
The availability of affordable commercial drones and dedicated software is making it possible to acquire a grid of images over an area and process them to obtain a digital model of the topography. This technology can be very useful when applied to the geological field work, where data are traditionally collected with the aim of reconstructing complex three dimensional geometries. The area was thoroughly studied during the past decades by means of traditional field work and several papers were published describing its features and evolution, a wealth of information was available as a useful reference for the flight planning and for the validation of the drone acquisition
