Municipalities that within their territory have a nuclear installation, different from a nuclear power plant. Municipalities with large ports or airports with a significant flow of radioactive goods are also included.

Coverage of the railway network affected by the transport of dangerous goods, representing the level of danger of each section in relation to the transport of dangerous goods. The danger level takes into account, apart from the flow of dangerous goods, the type of substances transported. The average data on the transport of dangerous goods from the last four years has been used with the aim of obtaining more stable data over time and minimizing the current variations derived from the socioeconomic context of each specific year.

Coverage prepared by the General Directorate of Civil Protection in which the municipality's obligation to prepare the Municipal Action Plan (PAM) for the risk of avalanches is represented, as well as the state of validity of the plan.

It indicates whether or not the municipality exceeds any of the thresholds established as a criterion to determine whether it is obliged or recommended to draw up the Municipal Action Plan for seismic emergencies. In order to establish the obligation to draw up the action manual for municipal seismic emergencies, there are two criteria: exceeding the intensity threshold in this case greater than or equal to VII, or for exceeding reference damage, in this case case more than 50 uninhabitable buildings or more than 10% of the total uninhabitable buildings in the municipality. Municipalities that appear in white mean that they do not exceed these thresholds.

It represents the areas susceptible to triggering avalanches and their extent, based on geomorphological criteria and the French model "Carte de Localisation des Phénomènes d'Avalanche" (CLPA).

Delimitation of the perimeter of industrial facilities included in Plaseqcat which handle dangerous substances.

This represents the alert coverage of sirens installed on dams. Some approximations have been made by generating buffers with a predefined coverage radius based on the technical specifications of the sirens, while others have employed acoustic propagation models that incorporate factors such as attenuation, sound dispersion, and the influence of topography.

It represents the aproximate route of the ethylene pipelines.

Identification of the municipalities through which the pipeline passes.

This dataset contains the geographical location of sirens installed on dams, designed to act as an alert system in the event of a dam or dike breach. The installation points have been determined based on acoustic dispersion models and an analysis of flood-prone areas with resident populations, aiming to optimize coverage and ensure immediate notification to the people living in these areas.
