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.

Thematic coverage of the municipalities of Catalonia in which the maximum danger level in relation to the transport of dangerous goods by rail is represented. 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. The danger may come from a section of the railway network that crosses the municipal area or by a section that, without crossing the territory, is at a distance equal to or less than 500 meters from the municipal area.

Thematic coverage of the municipalities of Catalonia in which the municipality's obligation or recommendation to draw up the Municipal Action Plan (PAM) for seismic risk is represented, as well as the plan's current status.

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.

Coverage of the road 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.

It represents the areas of winter observation of avalanches.

It delimits the security strip with control of compatible vulnerable elements (not residential or public concurrence except compatible industrial uses and other exceptions) to ensure the capacity of application of self-protection measures by the population based on the proximity of the population to Focus of the emergency, response time and possible effects.

Thematic coverage of the municipalities of Catalonia in which the municipality's obligation or recommendation to draw up the Municipal Action Plan (PAM) for the risk of snowfall is represented, as well as the plan's current status.

Thematic coverage of the municipalities of Catalonia in which the obligation or recommendation of the municipality to draw up the Municipal Action Plan (PAM) for chemical risk in the transport of dangerous goods by road and rail is represented, as well as the current status of the plan

It represents the areas of avalanche observation by the population, identified from a population survey.
