Risk zone layer

This layer shows seismic danger. It belongs to the subject of Natural Risk Areas in Annex III according to INSPIRE and Annex II to LISIGE under 12 Natural and Anthropic Hazard Zones. It expresses in relation to the value of gravity, g, the basic seismic acceleration, a (a characteristic value of the horizontal acceleration of the surface of the terrain) and the contribution coefficient K, which takes into account the influence of the different types of earthquakes expected on the seismic danger of each point. This layer is part of a service WMS 1.3.0 of the National Geographic Institute of Spain that complies with the definition of INSPIRE its Implementing Rules in relation to the requirements of a display service and the type of symbolism to be used. The NZ.HazardArea layer shows seismic acceleration values and municipalities.
