    Ancient Constructions as Markers of Tectonic Deformation (2008)
    Birkhauser Verlag,
    Details
    Publikationsdatum: 2017-04-04
    Beschreibung: Many ancient structures such as temples were constructed on the basis of a very strict plan and excellent workmanship. For this reason, even their slight deformation due to various effects (ground instability, earthquake oscillations, etc.) can be identified, and it is possible to discriminate between different types of deformation due to earthquakes and those due to other natural causes or to anthropogenic effects. Two study cases are presented here: the Propylaia on the Acropolis and the temple of Hephaistos (Hephaisteion) in the Agora at Athens. In both buildings deformation was produced by earthquakes.

    Macroseismic Intensity Modelling of Earthquakes in Southern Spain: Attenuation and Tectonic Implications (2008)
    Birkhauser Verlag,
    Details
    Publikationsdatum: 2017-04-04
    Beschreibung: A modelling of the observed macroseismic intensity of historical and instrumental earthquakes in southern Spain is proposed, with the aim of determining the macroseismic parameters for seismic hazard evaluation in a region in which the characterization of intensity distribution of seismic events shows different levels of difficulty referable to the complex faults system of the area in study. The adopted procedure allows an analytical determination of epicenters and principal attenuation directions of earthquakes with a double level of verification with reference to the maximum shaking area and structural lineaments of the region, respectively. The analyses, carried out on a suitable number of events, highlight, therefore, some elements for a preliminary characterization of a seismic zonation on the basis of the consistency between seismic intensity distribution of earthquakes and corresponding structural framework.

    Evidence of seismic deformation of the paved floor of the decumanus at Tindari (NE, Sicily) (2008)
    Blackwell Publishing Ltd
    Details
    Publikationsdatum: 2017-04-04
    Beschreibung: Most of the ancient town of Tindari (NE, Sicily) was settled on a plateau the most surficial layer of which was made of unconsolidated material. Ongoing excavations at the archaeological site at Tindari uncovered a large portion of the decumanus which suffered deformations preliminarily assigned to coseismic effects. An analysis of the local dynamic response through the simulation of strong seismic shaking to the bedrock and modelling of spectral ratios of the bedrock-soft soil was carried out to verify the susceptibility of superficial terrains of the promontory to coseismic deformations. To perform this simulation the finite element method (FEM) was used. Four accelerometric recordings of three earthquakes of medium-high magnitude, recorded on rocky sites, were chosen to simulate the seismic shaking, using a constitutive law for the materials composing the promontory layers both of linear-elastic type and of elastoplastic type. The analysis of the linear-elastic field allowed the definition of the frequencies for which the spectral ratios of the accelerations recorded the highest amplifications; in particular the frequency range 31.5–37.2 Hz can be combined with deformation of the paved floor of the decumanus. The analysis in the elastoplastic field highlighted the zones of promontory more susceptible to suffer plasticization process. The results show that the topmost layer of the decumanus is the most susceptible to suffer plasticization. Therefore, the performed analysis lends greater support to the hypothesis that the deformations were produced by seismic shaking.

    An Anisotropic Attenuation Law of Macroseismic Intensity Performed on Virtual Intensity Distribution of Seismogenic Zones (2008)
    Birkhauser Verlag,
    Details
    Publikationsdatum: 2017-04-04
    Beschreibung: An anisotropic attenuation law, based on an anisotropic characterization of intensity distribution for seismogenic zones, is proposed. This approach, that distinguishes itself for its consistency to the observed data, initially reconfigured by filtering procedures, is particularly suitable for seismic hazard evaluation.

    New results of 40Ar/39Ar dating constrain the timing of transition from fissure-type to central volcanism at Mount Etna (Italy) (2008)
    Blackwell Publishing Ltd
    Details
    Publikationsdatum: 2017-04-04
    Beschreibung: Recent geological studies performed at Etna allow reassessing the stratigraphic frame of the volcano where distinct evolutionary phases are defined. This stratigraphic reconstruction was chronologically constrained on the basis of a limited number of U–Th and K–Ar age determinations whose uncertainty margins are sometimes too wide. For this reason, we successfully adopted at Etna the 40Ar/39Ar technique that allowed obtaining more precise age determinations. The incremental heating technique also gives information on sample homogeneity, and potential problems of trapped argon. Five samples were collected from stratigraphically well-controlled volcanic units in order to chronologically define the transition between the fissure-type volcanism of the Timpe phase to the central volcanism of the Valle del Bove Centers. Isotopic ages with an uncertainty margin of 2–4% have been obtained emphasizing that this transition occurred (130– 126 ka) without significant temporal hiatus.

    Macroseismic Parameters of Seismogenic Zones of Calabria and Sicily for Seismic Hazard Evaluation (2008)
    Birkhauser Verlag,
    Details
    Publikationsdatum: 2017-04-04
    Beschreibung: For the seismic hazard evaluation of the region including the southern Calabro- Peloritanian Arc and southeastern Sicily, the determination of the macroseismic virtual intensity distributions has been carried out, characteristic of the seismogenic zones that fall within the area in study, starting with the structural framework of the region and from the analysis of the observed intensity effected through suitable filters. The macroseismic parameters, derived from such virtual distributions and used for seismic hazard evaluation, are not only a reference for eventual subsequently deeper knowledge referable to the need for a better characterization of the reference modelling, but distinguish themselves as an essential instrument for the definition of seismic hazard scenarios correlated to seismic events that take place in single seismogenic zones.
