The Natural Disasters Picture System (NDPS) is a picture database dedicated to natural hazards and their impacts on the environment and humans. The NDPS was made possible by the partnership between the Laboratoire de Psychologie Sociale et Cognitive (LAPSCO) and the Laboratoire Magmas & Volcans (LMV) under the Clermont-Ferrand Center for Volcano Research (ClerVolc Excellence Laboratory).

The NDPS is a set of 154 pictures of various natural hazards (e.g., earthquakes, hurricanes, tornadoes), including an extended set of pictures of volcanic hazards (e.g., eruptions, lava flows, ash and lapilli falls, and pyroclastic flows), aftermaths and victims. We examined the emotion elicited by each picture on the basis of appraisal theories by using the dimensions of valence, arousal, dominance and certainty. The best-fitting emotion of each picture was determined on the basis of its dimensional pattern by the use of a Hierarchical Ascendant Classification.
