Short summary
The paper presents field evidence and a kinematic study of rock block motion mobilized by a Mw = 6.5 earthquake near the island of Lefkada on 17 November 2015. A detailed survey was conducted using an unmanned aerial vehicle (UAV). Using the impact points from the actual rockfall trajectory, an analytical approach to reconstruct the trajectory was implemented using 2-D, 3-D and kinematic analyses. The actual trajectory could not be accurately predicted, revealing limitations of existing models.
