Fig. 4

Three consecutive timesteps of UAV imagery (10, 12 and 15 August) showing the same sub-section of coastline during the 2019 open water season. The timesteps show a section of coast were block failures occurred in three successive timesteps. The failures occurred from an east to west direction. These failures likely represent post storm lag of block failure from a storm that occurred within the 30 July to 2 August timestep.
