Abstract. A comprehensive understanding of rockfall trajectories holds the promise to enhance the application of numericalmodels for engineering hazard analysis. Here, we present a full three-dimensional trajectory reconstruction of the Chant Sura EOTA221 rockfall experiment. The data analysis allows a complete kinematic description of a rock’s trajectory in real terrain and underscores the physical complexity of rock-ground interactions. In-situ accelerometer and gyroscope data are combined with videogrammetric and unmanned aerial systems mapping techniques to understand the role of rock rotations, ground penetration and translational scarring in rockfall motion. The exhaustive trajectory reconstruction provides information over the complete flight path such as translational velocity vectors, angular velocities, impact duration and forces, ballistic jump heights and lengths. The experimental data provides insight into the basic physical processes detailing how rotating rocks of general shape penetrate, rebound and scar ground terrain. The data serves in future as a calibration basement to enhance numericalrockfall modelling.

Short summary
Given the task of a rockfall hazard assessment, knowledge about the precise flight path of assumed boulders is vital for its accuracy. We present the full reconstruction of artificially induced rockfall events. The extracted information such as exact velocities, jump heights and lengths provide detailed insights of how rotating rocks interact with the ground. The information serves as future calibrations of rockfall modelling tools with the goal of even more realistic modelling predictions.
