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.

The ZIF (defenceless zone) is defined as the minimum security zone necessary to guarantee the viability of self-protection of vulnerable elements in the context of an accident in the transport of dangerous goods. The extension of this zone is conditioned by the necessary response time and the intensity of the effects of foreseeable accidents. The distances of the ZIF for the scenarios of long-range toxic cloud, short-range toxic cloud, serious explosion, flammable cloud and puddle fire are established in "The Technical Instruction of the DGPC regarding the preparation of reports on the conditions minimum requirements that new urban developments must comply with to be located within the identified chemical risk zones due to the transport of dangerous goods by road and rail" (ITMMPP).

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

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

Thematic coverage of the municipalities of Catalonia in which the obligation of the municipality to prepare the Basic Municipal Emergency Plan (PBEM) is represented due to the risk of emergency in passenger rail transport, the reason for this and the state of validity of the plan.

Aeronautical emergency planning zones based on the probability of impact in the vicinity of the airport, aerodrome or heliport. The models used allow the calculation of the probability that, given an accident in the vicinity of an aeronautical installation, the aircraft will impact at a specific point. Two types of zone are defined: Zone I corresponds to the territory with a probability of impact greater than 10% (10e-1) and Zone II corresponds to the territory with a probability of impact greater than 1% (10-2).

It represents the areas of winter observation of avalanches.

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 municipality's obligation or recommendation to draw up the Municipal Action Plan (PAM) for radiological risk is represented, as well as the plan's current status.

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 an aeronautical emergency is represented, as well as the plan's current status.
