It represents the time of avenue or arrival of the floods from sectorizations of the fluvial courses.

Identification of the municipalities through which the ethylene pipeline passes.

Seismic intensity (MSK scale) that can be expected for a return period of 500 years

It represents the aproximate route of the oil pipelines.

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.

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.

Thematic coverage of the municipalities of Catalonia in which the obligation or recommendation of the municipality to draw up the Specific Municipal Plan (PEM) for emergencies due to episodes of pollution downstream of the Flix reservoir is represented, as well as the current status of the plan

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.

It represents the aproximate route of the ethylene pipelines.

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.
