Simple download service (Atom) of the dataset: Natural Risk Prevention Plan (NRPP) hazard zone for field and seismic movements of the Ribeauvillé region of the Haut-Rhin

Area exposed to one or more hazards represented on the hazard map used for risk analysis of the RPP. The hazard map is the result of the study of hazards, the objective of which is to assess the intensity of each hazard at any point in the study area. The evaluation method is specific to each hazard type. It leads to the delimitation of a set of areas on the study perimeter constituting a zoning graduated according to the level of the hazard. The allocation of a hazard level at a given point in the territory takes into account the probability of occurrence of the dangerous phenomenon and its degree of intensity. For multi-random PPRNs, each zone is usually identified on the hazard map by a code for each hazard to which it is exposed. All hazard areas shown on the hazard map are included. Areas protected by protective structures must be represented (possibly in a specific way) as they are always considered subject to hazard (case of breakage or inadequacy of the structure). Hazard zones can be described as developed data to the extent that they result from a synthesis using multiple sources of calculated, modelled or observed hazard data. These source data are not concerned by this class of objects but by another standard dealing with the knowledge of hazards. Some areas within the study area are considered “no or insignificant hazard zones”. These are the areas where the hazard has been studied and is nil. These areas are not included in the object class and do not have to be represented as hazard zones. However, in the case of natural RPPs, regulatory zoning may classify certain areas not exposed to hazard as prescribing areas (see definition of the PPR class).本数据集对应于用于反应堆保护规程（RPP）风险分析的灾害地图所标注的、受一种或多种灾害影响的区域。 该灾害地图为灾害研究的成果，其核心目标为评估研究区域内任意点位的各类灾害强度。针对不同灾害类型，需采用专属的评估方法，最终在研究范围内划定若干区域，形成按灾害等级分级的分区区划。在区域内某一特定点位分配灾害等级时，需综合考量该危险现象的发生概率及其强度等级。 针对多随机PPRNs，灾害地图上的每个分区通常会通过其受影响的各类灾害对应的专属编码进行标识。 灾害地图上标注的所有灾害影响区域均需纳入本数据集。受防护结构保护的区域也必须（可通过专属标注方式）予以标注，因为此类区域始终存在受灾害影响的风险，例如结构破损或防护失效的情况。 灾害分区可被视为经开发的数据集，其生成依托对多源计算、建模或实测灾害数据的综合整合。本对象类不涉及这些源数据，相关源数据由另一项针对灾害认知的标准进行规范。 研究区域内的部分区域被划分为"无灾害或灾害可忽略区域"，即经研究确认灾害风险为零的区域。此类区域不属于本对象类范畴，无需作为灾害分区进行标注。但针对天然反应堆保护规程场景，监管区划可能将部分未受灾害影响的区域归类为规定区域（详见PPR类（PPR class）的定义）。
