AB Carbonate rocks are frequently affected by dissolution from rainfall and groundwater. As dissolutionprogress, the roof of the cavities can rapidly collapse originating landforms named sinkholes. When thiskind of structures affect to human activities, they constitute a serious natural hazard. The province ofSegovia has abundant examples of karst features developed on carbonate rocks. The ‘Sima de Madrona’,a collapse sinkhole located near the city of Segovia, constitutes one of these examples. The aim of thiswork is to determine the presence of galleries and cavities around this karst feature by means of shallowgeophysical techniques, in order to assess the collapse risk of the area. The joint use of Ground-penetratingRadar and Electrical Resistivity Tomography has allowed determining the presence of two cavities relatedto the sinkhole development. The detection of these small galleries can affect the anthropogenic activitiesof the area and so, it constitutes a natural risk that has to be taken into account in order to minimize thedamages that the collapse of these structures could produce
