The paper presents field evidence and a kinematical study of the motion of co-seismic rockfall during a Mw
6.5 earthquake in Lefkada island in 2015. A detailed field survey using an Unmanned Aerial Vehicle (UAV) was deployed. Using the impact points from the actual rockfall trajectory, an analytical approach to reconstruct the trajectory was implemented, using 2D, 3D and kinematic analyses. The actual trajectory could not be accurately revealing limitations of existing models.
