Plan for the prevention of natural risks of field movement — Commune de Fauroux — Occurrence of risk — Department of Tarn-et-Garonne

The origin of the risk characterises the real-world entity which, through its presence, represents a potential risk. This origin may be characterised by a name and, in some cases, a geographical object locating the actual entity causing the risk. The location of the entity and the knowledge of the dangerous phenomenon are used to define the risk pools, the risk-exposed areas that underpin the RPP. For NRPPs, this entity may, for example, correspond to a watercourse, a geologically unstable area.风险源是指凭借自身存在即可构成潜在风险的现实实体。该风险源可通过名称予以表征，在部分情形下还可通过用于定位该致险实体的地理对象来标识。实体的位置与危险现象的相关认知，可用于划定风险池（risk pools）——即支撑RPP的风险暴露区域。 针对NRPPs而言，该实体例如可对应为河道、地质不稳定区域。
