Topographic amplification from recorded earthquake data and numerical simulations
No full textWith the aim of contributing to the refinement of the next generation of tools for seismic hazard analyses, we present here an attempt at including topographic amplification factors in GMPEs, thus broadening the traditional options for site effects. With a view to critically discuss and complement with new data the approach of Cauzzi et al. (2010) and Paolucci (2002), information from additional numerical models including crustal layering are taken into account. The indications obtained from the numerical simulations are cross-checked against and consolidated by analyses of the residuals of a selection of strong- and weak-motion observations on topographic
reliefs in Italy and Switzerland (carefully selected via GIS) with respect to a set of largely used GMPEs.PublishedLisbon, Portugal4.1. Metodologie sismologiche per l'ingegneria sismicaope

1D and 2D site amplification effects at Tarcento(Friuli, NE Italy), 30 years later
No full textA temporary accelerometer network has been installed in Tarcento (Friuli, NE Italy), a small town heavily hit by the 1976–1977 Friuli earthquake sequence, as a part of an ongoing research
project aimed at ground motion simulation and generation of shakemaps in the near-field of an earthquake. The network operated from October 2008 to April 2010 and consisted of three
K2 accelerographs with internal Episensor, distributed over a linear array of about 1.5 km length. Tarcento town had been chosen, at the end of the 1970s, as the ideal site for a pilot microzonation study, the first of this kind in Italy, in which a substantial number of field (and laboratory) tests were carried out in order to assess the mechanical properties of local alluvium deposits and their complex (3D) geometrical configuration. The data from the temporary network, illustrated herein, allow for proper verification and review of some of the quantitative predictions formulated in the 1980 study. As argued in the discussion section, we also believe that the data are apt to provide
valuable information of more general interest on the complex seismic response of alluvium-filled valleys, and we show therein how the observations can be interpreted in the light of presently available parametric simulation studies and simplified criteria for handling basin amplification effects
