Short summary
Geohazards occur more often and at larger scale due to climate change. In this study, we used for the first time automated drone docks to monitor geohazards at 3 different sites in Norway and Switzerland. We present a monitoring workflow for automated Uncrewed Aerial Vehicle operations which can produce frequent, detailed maps showing surface change and displacement. Our results show how this approach can improve future hazard monitoring and early warning and help to protect communities at risk.
