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

Location of alarms to warn the population if there is a chemical risk in the case of an accident in premises nearby.

Polygons which define the range of sound corresponding to the alarms. In accordance with each type of alarm, the sound radius covered can be 800 or 400 metres away from the siren, or maybe unidirectional, covering a distance of 700 m with a 70º opening.

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.

Identification of the municipalities through which the pipeline passes.

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 forest fires is represented, as well as the plan's current status.

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).

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

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 defines the maximum intervention zone and alert zone associated with an industrial establishment. If there are a group of industrial establishments located nearby in the territory, the maximum intervention and alert zone will be the total of these types of zones for all establishments in the event that the zones overlap. The intervention zone is the zone in which the consequences of accidents produce a level of damage that justifies the immediate application of protective measures. The alert zone is the zone in which the consequences of accidents cause effects that, although perceptible to the population, do not justify intervention, except for critical population groups. Likewise, in relation to resolution IRP/971/2010, of March 31, which publicizes the criteria for the preparation of reports referring to the control of the implementation of new vulnerable elements compatible with the management of civil protection risks, the maximum intervention zone coincides with the general confinement zone that corresponds to the strip with control of vulnerability and maximum permitted growth with the ultimate objective of allowing the population to be warned and the application of self-protection.
