Abstract: This disclosure relates to analysing rock falls. A video camera captures video data, a depth measurement system captures depth data, a seismic sensor captures seismic data, and a data store stores spatial characterising data of the rock fall site. A processor detects a rock fall source location based on the video data, depth data, seismic data; determines a three-dimensional free fall estimation based on the rock fall source location; estimates three-dimensional bounce kinematics based on the three-dimensional free fall estimation and the spatial characterising data of the rock fall site; estimates a runout based on the rock fall source location, free fall and bounce kinematics; and combines the rock fall source location, the three-dimensional free fall, the three dimensional bounce kinematics and the runout to determine a rock fall trajectory.
