Abstract: "Il 20 maggio 2012 in Pianura Padana è iniziata una sequenza sismica che ha interessato una vasta area compresa tra le Province di Reggio Emilia, Modena, Mantova, Bologna e Ferrara. La prima forte scossa, di magnitudo locale ML=5,9, è avvenuta alle 4:03 ora locale, con epicentro tra Mirandola e Finale Emilia, seguita, nel giro […]
Abstract: "In this paper, we address the issue of evaluating the seismic site response for sites located on large alluvial plains, for which no reference sites can be identified, but some earthquakes can be simultaneously recorded at both surface and depth. In the proposed method, surface and borehole records are firstly used to assess the […]
Abstract: "Results of an extensive ambient vibration surveys carried out by different research teams in the area damaged by May–June 2012 seismic sequence in Emilia Romagna (Northern Italy) are summarized and analysed. In particular, ambient vibrations were acquired by both single station and seismic array configurations. Average horizontal to vertical spectral ratios (HVSR) at single […]
Abstract: "Soil liquefaction can result in significant settlement and reduction of load-bearing capacity. Moreover, the increase and the accumulation of pore pressure during an earthquake and its post-seismic dissipation can generate permanent deformations and settlements. The quantitative evaluation of post-liquefaction settlements is of extreme importance for engineering purposes, i.e. for earthquake-resistant design of new buildings […]
Abstract: "Dal 2004, anno di pubblicazione della prima carta sismotettonica della Regione Emilia-Romagna, molte cose sono successe e nuove conoscenze sono state acquisite. Le reti sismiche sono state implementate, la Pianura Padana e l’Appennino settentrionale sono stati interessati da varie sequenze sismiche e nuovi studi sono stati effettuati. Ciò ha permesso di acquisire una considerevole […]
