    Seismic Anisotropy beneath Northern Victoria Land from SKS Splitting Analysis (2005)
    Springer-Verlag, Berlin Heidelberg New York
    Details
    Publication Date: 2017-04-04
    Description: Abstract. Teleseismic data recorded by temporary and permanent stations located in the Northern Victoria Land region are analysed in order to identify the presence and location of seismic anisotropy. We work on data recorded by 24 temporary seismographic stations deployed between 1993 and 2000 in different zones of the Northern Victoria Land, and by the permanent very broad-band stations TNV located near the Italian Base M. Zucchelli. The temporary networks monitored an area extending from Terra Nova Bay towards the South beyond the David Glacier and up to the Indian Ocean northward. To better constrain our study, we also provide an analysis of data recorded by TNV in the same period of time and we take into account also SKS shear wave splitting measurements performed by Barruol and Hoffman (1999) on data recorded by DRV. This study, to be considered as preliminary, reveals the presence of seismic anisotropy below the study region, with a mainly NW-SE fast velocity direction below the Terra Nova Bay area and rather large delay times, that mean a deep rooted anisotropic layer.

    The Subduction Structure of the Northern Apennines: Results from the RETREAT Seismic Deployment (2007)
    Details
    Publication Date: 2017-04-04
    Description: The project Retreating-trench, extension, and accretion tectonics, RETREAT, is a multidisciplinary study of the Northern Apennines (www.geology.yale.edu/RETREAT/index.htm), is funded by the United States National Science Foundation (NSF) in collaboration with the Italian Istituto Nazionale di Geofisica e Vulcanologia (INGV) and the Grant Agency of the Czech Academy of Sciences (GAAV). The main goal of RETREAT is to develop a self-consistent dynamic model of syn-convergent extension, using the Northern Apennines as a natural laboratory. In the context of this project a passive seismological experiment was deployed in the fall of 2003 for a period of three years. RETREAT seismologists aim to develop a comprehensive understanding of the deep structure beneath the Northern Apennines, with particular attention on inferring likely patterns of mantle flow. Specific objectives of the project are the crustal and lithospheric thicknesses, the location and geometry of the Adriatic slab, and the distribution of seismic anisotropy laterally and vertically in the lithosphere and asthenosphere. The project is collecting teleseismic and regional earthquake data for 3 years. This contribution describes the RETREAT seismic deployment and reports on key results from the first year of the deployment. We confirm some prior findings regarding the seismic structure of central Italy, but our observations also highlight the complexity of the Northern Apennines subduction system.

    European–Mediterranean Regional Centroid Moment Tensor catalog: Solutions for years 2003 and 2004 (2007)
    Elsevier
    Details
    Publication Date: 2017-04-04
    Description: We present an update, for years 2003 and 2004, of the European– Mediterranean Regional Centroid Moment Tensor (RCMT) catalog that we maintain since 1997. This update adds 177 new solutions to the database, relating to moderate-magnitude (4.5 ≤M〈5.5) earthquakes. About 30% of our new solutions also appear in the global CMT catalog: comparison of the two independent determinations generally shows very good agreement.Within the time span covered, the most noticeable seismic sequences occurred in Northern Africa (Boumerdes, Algerian coast in 2003 and Al Hoceima, Morocco in 2004) and in Southern Greece and Dodecanese region (August 2003 and 2004). The complete RCMT catalog for the European and Mediterranean region now covers 8 years, and contains about 600 solutions.

    Seismic Anisotropy in the Victoria Land Region (Antarctica) (2010)
    Details
    Publication Date: 2017-04-04
    Description: We present shear-wave splitting results obtained from analysis of core refracted teleseismic phases recorded by permanent and temporary seismographic stations located in the Victoria Land region (Antarctica). We used eigenvalue technique to linearize the rotated and shifted shear-wave particle motion, in order to determine the best splitting parameters. A well-scattered distribution of single shear-wave measurements has been obtained. Average values show clearly that dominant fast axis direction is NE-SW oriented, accordingly with previous measurements obtained around this zone. Only two stations, OHG and STAR show different orientations, with N-S and NNW-SSE main directions. On the basis of the periodicity of single shear-wave splitting measurements with respect to back-azimuths of events under study, we inferred the presence of lateral and vertical changes in the deep anisotropy direction. To test this hypothesis we have modelling waveforms using a cross-convolution technique in one and two anisotropic layer's cases. We obtained a significant improvement on the misfit in the double layer case for the cited couple of stations. For stations where a multi-layer structure does not fit, we looked for evidences of lateral anisotropy changes at depth through Fresnel zone computation. As expected, we find that anisotropy beneath the Transantarctic Mountains (TAM) is considerably different from that beneath the Ross Sea. This feature influences the measurement distribution for the two permanent stations TNV and VNDA. Our results show a dominant NE-SW direction over the entire region, but other anisotropy directions are present and find an interpretation when examined in the context of regional tectonics.

    Regional Moment Tensor Review: An Example from the 2 European–Mediterranean Region (2015)
    Springer-Verlag Berlin Heidelberg
    Details
    Publication Date: 2017-04-04
    Description: The seismic moment tensor is the complete mathematical representation of the movement on a fault 10 during an earthquake, comprising of the couples of forces that produced it, the description of the fault 11 geometry, and its size by means of the scalar seismic moment M0. 12 The computation of seismic moment tensor has become a widely diffused activity because of the 13 relevance of this kind of data in seismotectonic and geodynamic studies and, in more recent times, 14 because it allows obtaining rapid information about a seismic event immediately after its occurrence. This 15 progress has been possible with the advent of modern standardized instruments since the early 1960s, 16 above all of the very broadband seismographic stations that started to record in the late 1970s. Further- 17 more, time after time, the easier availability of digital data impressed a strong incentive to improve the 18 procedures of source parameter computation.

    Pianificazione e preparazione dell’emergenza. L’esercitazione a Santa Sofia (FC) del 26/30 settembre 2011: un esempio di gestione di una crisi sismica (2013)
    Details
    Publication Date: 2020-02-24
    Description: Nell’ambito della convenzione vigente tra l’Istituto Nazionale di Geofisica e Vulcanologia (INGV) e l’Agenzia di Protezione Civile della Regione Emilia Romagna è stata realizzata a fine settembre del 2011 una esercitazione sul rischio sismico con l’obiettivo di valutare il livello raggiunto nelle procedure che entrambi gli Enti attivano in occasione di una emergenza a seguito di un forte terremoto. La simulazione ha interessato oltre 50 unità di personale INGV, sia in sede che in area epicentrale, appartenenti a diverse Sezioni e sedi INGV (Ancona, Arezzo, Bologna, Irpinia, Milano, Pisa e Roma). La preparazione dell’evento si è fondata sulle esperienze del passato, in primis la lunga emergenza aquilana del 2009 [Margheriti et al., 2010; 2011; Moretti et al., 2011c], con uno sguardo alle nuove esigenze sia interne che esterne (ad esempio le istanze della Protezione Civile). Nonostante gli imprevisti e gli inevitabili errori commessi a cui si aggiunga lo sforzo per mettere insieme tante differenti professionalità e per rispettare sempre al meglio il programma e gli impegni presi con i responsabili dell’Agenzia di Protezione Civile della Regione Emilia Romagna, è stato ampiamente ripagato dall’aver vissuto un’esperienza positiva non solo da un punto di vista professionale ma anche umano. Questa esercitazione si è infatti rivelata un’importante occasione per relazionarsi e confrontarsi con i colleghi solitamente lontani rendendosi conto che da ciascuno di loro è sempre possibile imparare qualcosa. Questa esperienza si è mostrata di fondamentale importanza nella gestione dell’emergenza verificatasi a maggio 2012 in Pianura Padana emiliana [Moretti et al., 2012].
