PPRN — Origin of Risk Field Movement — Coteau de Moselle — CHAVIGNY (54123)

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.风险来源所表征的现实实体，其存在本身即构成潜在风险。该风险来源可通过名称进行表征，在部分场景下还可通过定位该实际致险实体的地理对象来进一步明确。实体的位置以及对危险现象的相关认知，可用于界定风险池（risk pool）——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水道或地质不稳定区域。
