Aproximación a la vulnerabilidad sísmica de las edificaciones mediante SIG: la serie sísmica de la Vega de Granada (2020-2021) = Approach to the seismic vulnerability of buildings through GIS: the seismic series of the Vega de Granada (2020-2021).

La Vega de Granada is one of the Spanish regions with the highest seismic hazard, where important events with macroseismic intensity (Io)≥VIII have been recorded. At the end of 2020 a seismic series began (still active, in March 2021), which has reached an Io=V-VI. In the framework of seismic risk studies, it is necessary to know the vulnerability of buildings. Thus, this research aims to estimate relative vulnerability values of buildings. For this purpose, a multi-criteria analysis was carried out based on information from the Cadastre and the National Geographic Institute, as well as on the dates of seismic-resistant regulations. A free geographic information system was used for data integration, calculations, representation and analysis. The results show that the area west of Santa Fe is the most likely to be affected.
