WP8 Modelling of topographic signal: GIS-BASED data base of potential earthquake sources identified in suitable kei-areas
No full textGIS-based database of potential earthquake sources that were identified in key areas, such as the Provence, France, Po Plain, Italy, Outer Jura, Switzerland. The seismogenic source is defined as in Valensise and Pantosti (2001) following the scheme de-veloped in the framework of the EC project FAUST (Valensise et al., 2002).Istituto Nazionale di Geofisica e Vulcanologia, (Rome, Italy)Publishedope

WP#4 slow active faults in compressional settings: Methodologies, result and source parameters on site - The Po Plain
No full textThis 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).Istituto Nazionale di Geofisica e Vulcanologia

From earthquake intensities to earhquake sources: Extending the contribution of historical seismology to seismotectonic studies
No full textThe epicentral locations and magnitudes of the events reported in the Catalogue of Strong Italian Earthquakes are obtained from intensity data through a standardized and established algorithm. However, we contend that the dense and homogeneously collected data sets presented in this catalogue can also be used to assess the location, physical dimensions and orientation of the earthquake source on purely historical grounds. The method we describe is of special value for older earthquakes and for all events that fall in areas where the understanding of faulting and tectonics is limited. At the end of the calculations the seismic source is represented as an oriented «rectangles», the length and width of which are obtained from moment magnitude through empirical relationships. This rectangle is meant to represent the actual surface projection of the seismogenic fault or, at least, the projection of the portion of the Earth crust where a given seismic source is likely to be located. Sources derived through this procedure can then be juxtaposed to sources derived from instrumental and geological data for constructing fault segmentation and earthquake recurrence models and for highlighting linear gaps in the global seismic release. To test the method we applied it systematically to all M > 5.5 earthquakes that occurred in the Central and Southern Apennines in the past four centuries. The results are encouraging and compare well with existing instrumental, direct geological and geodynamic evidence. The method is quite stable for different choices of the algorithm parameters and provides elongation directions which in most cases can be shown to be statistically significant. The resulting pattern of source locations and orientations is homogeneous, showing a consistent Apennines-parallel trend that agrees well with the NE-SW tectonic extension style of the central and southern portions of the Italian peninsula
Reply to “Comment on ‘The 28 December 1908 Messina Straits Earthquake (Mw 7.1): A Great Earthquake throughout a Century of Seismology,’ by N. A. Pino, A. Piatanesi, G. Valensise, and E. Boschi” by A. Amoruso, L. Crescentini, and R. Scarpa
No full textThis is a rather unusual comment that focuses on how a specific figure was constructed rather than on actual scientific results. The figure in question (Figure 9 from Pino et al. 2009) does not even show new data or results, but is simply a summary of slip models that have been proposed in the literature for the 1908 earthquake. All models describe slip distributions from coseismic elevation changes except for one, derived by Pino et al. (2000) based on waveform modeling of historical seismograms
