This paper presents a performance-based earthquake assessment of an industrial structure, aiming at identifying suitable techniques to select and scale natural ground motions for 3D analysis and improve the structural response prediction of complex structures. To this end, an industrial structure characterized by the presence of large masses placed at a significant height and of different horizontal resisting systems, such as moment resisting frames, inverted V bracings and diagonal bracings, is investigated.

The present paper reports the results of a mineralogical and petrographic study focused on the archaeometric characterization of Early Bronze Age pottery from the archaeological site of Khirbet al-Batrawy (Jordan), dated between 3000 and 2000 BC. Optical microscopy (OM) and X-ray powder diffraction (XRPD) analyses are used to define the nature of the raw material, the technology of the ceramic production and their developing during the centuries.

The aim of the paper is to provide quantitative elements on the mechanisms that controlled the slope instabilities occurred after two major recent eruptions at Stromboli volcano (i.e. 2002–2003 and 2007). After a brief description of the geological setting and of the largest well documented instability phenomena on volcano flanks, the main objective is pursued using three-dimensional stress-strain analyses for modelling the effects of the magma intrusion on the stability of the volcano flank.
