WP#4 slow active faults in compressional settings: Methodologies, result and source parameters on site - The Po Plain

Abstract

This deliverable is subdivided into two parts. Part 1 presents a summary of methodologies employed in the investigation of slow active faults in the Po Plain. The methodologies are briefly described with the support of images taken from reports and papers partially or totally developed within SAFE. Part 2 presents a summary of results and parameters obtained for Po Plain faults/seismogenic sources. The reader should be aware that these results are described in detail in Deliverable 8.2 “Detailed characterisation of individual structures” within WP8 “Modelling of topographic signal”. This is due to the fact that the Po Plain is dominated by blind faulting and that most of the methodologies developed to investigate this region are based on observations and analyses of the topography and lanscape. The source parameters are described with reference to the GIS-based database of potential earthquake sources developed within SAFE by INGV. This database, that was largely modelled and formatted according to the criteria set forth by the EC project “Faust” (Valensise et al., 2002), is fully described and supplied in electronic form as Deliverable 8.1 “GIS-based database of potential earthquake sources identified in suitable key-areas”. Finally, recall that individual seismogenic sources are defined as in Valensise and Pantosti (2001).
