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

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

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 aproximate route of the oil pipelines.

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).

Areas potentially floodable according to geomorphological criteria.

Identification of the municipalities through which the ethylene pipeline passes.

Delimitation of the security band with control of compatible vulnerable elements (no residential use and public concurrence, except for compatible industrial uses) based on the zone of limit effects or extremes outside, that is, this area includes the area where the consequences about the population or vulnerable elements are especially significant due to the special intensity of the effects of the emergency.
