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

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.

Identification of the municipalities through which the gas pipeline passes in the operational phase.

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).

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.

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.

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

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.

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 of winter observation of avalanches.
