Cliff coasts are magnificent interfaces between the continents and the sea with stark contrasts in topography and process dynamics. Collapses events range over many orders of magnitude in size and recurrence intervals. Cliff collapse processes are rapid and hard to predict, yet they have key impact on the terrestrial landscape and coast line, the marine ecosystem and sedimentation routing patterns, and impose a hazard on human infrastructure. The cliff coast of Germany’s largest Island, Rügen, is monitored by a network of broadband seismometers , a telemetering seismic antenna and repeat UAV surveys to detect, locate, analyse collapse events but also to screen for early warning signals.
