    Convergence vs. retreat in Southern Tyrrhenian Sea: Insights from kinematics (2007)
    AGU
    Details
    Publication Date: 2017-04-04
    Description: The Tyrrhenian Sea is an extensional basin opened by trench retreat and back-arc extension during subduction of the Calabrian slab in the last 10–12 My. Subduction is still active beneath the SEmost part of the Tyrrhenian Sea, as testified by seismicity down to 500 km depth. By analyzing seismicity and geodetic data, together with recent tomographic images, we define the present-day situation. An evident N-S compressional regime prevails in the Tyrrhenian region west of the Aeolian archipelago, while east of them a NNW-SSE extension is documented by focal mechanisms and GPS data, with a much smaller strain rate with respect to the past. The transition between these two domains is accommodated by a N-S discontinuity zone which runs from Aeolian Islands to Mt. Etna with an extensional to strike-slip deformation.

    Seismic moment tensors of the April 2009, L’Aquila (Central Italy), (2009)
    Wiley-Blackwell
    Details
    Publication Date: 2017-04-04
    Description: On 2009 April 6, the Central Apennines were hit by an Mw = 6.3 earthquake. The region had been shaken since 2008 October by seismic activity that culminated in two foreshocks with Mw 〉 4, 1 week and a few hours before the main shock. We computed seismic moment tensors for 26 events with Mw between 3.9 and 6.3, using the Regional Centroid Moment Tensor (RCMT) scheme. Most of these source parameters have been computed within 1 hr after the earthquake and rapidly revised successively. The focal mechanisms are all extensional, with a variable and sometimes significant strike-slip component. This geometry agrees with the NE–SW extensional deformation of the Apennines, known from previous seismic and geodetic observations. Events group into three clusters. Those located in the southern area have larger centroid depths and a wider distribution of T-axis directions. These differences suggest that towards south a different fault systemwas activated with respect to the SW-dipping normal faults beneath L’Aquila and more to the north.

    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.

    Seismic strain and stress field studies in Italy before and after the Umbria-Marche seismic sequence: a review (2008)
    Editrice Compositori
    Details
    Publication Date: 2019-11-04
    Description: The seismic sequence that hit Umbria and Marche during 1997 and 1998 was particularly significant because it dramatically marked the evolution of analysis tools and the development of our geophysical knowledge of the region. Since September 1997, we have had a growing, coherent catalogue of source moment tensors that provides reliable information on earthquake sources in Italy and the surrounding regions. Together with borehole and other tectonic data, this has conspicuously improved our knowledge of the regional strain and stress fields. The main impact of these new data that include local information consists of the possibility to change the scale of the regional geodynamic frame. The simple description of extension tectonics that dominate the Apennines belt has evolved into the present-day maps of the strain and stress fields, where the active tectonics involve compression in the eastern Alps, extension and compression fronts in the northern Apennines, extension and strike-slip structures in the southern Apennines, and a compressional front along the southern Tyrrhenian Sea. This recent geodynamic evolution and the present-day seismotectonic sketch of the Italian peninsula are here described on the basis of the recognition of these tectonic features.

    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].

    OMBRA: Observing Montello BRoad Activity. Una rete temporanea per lo studio dei processi di deformazione attraverso la faglia del Montello (Alpi orientali). (2012)
    Istituto Nazionale di Geofisica e Vulcanologia
    Details
    Publication Date: 2017-04-04
    Description: L’area veneta delle Alpi orientali è caratterizzata da una debole sismicità di background. In particolare, l’attività sismica registrata negli ultimi 30 anni [Castello et al., 2006; Bollettino Sismico INGV1] mostra eventi di bassa energia (ML〈3) lungo l’arco alpino in corrispondenza dell’anticlinale del Montello (situato a NW di Treviso). Sono noti però alcuni eventi di magnitudo medio-alta che hanno storicamente interessato la regione: l’episodio più significativo è il terremoto di Asolo del 1695 (Imax 10 e MaW 6.61), affiancato da tre ulteriori eventi sismici di intensità Imax≥VIII (magnitudo equivalente 6.0) avvenuti nel 778, 1286 e 1836 [CPTI Working group 2004] (Figura 1). Il Montello è catalogato tra i segmenti sismogeneticamente attivi del fronte alpino [Valensise and Pantosti, 2001; Galadini et al., 2005; Poli et al., 2008], originato dall’uplift di una struttura di thrust S-vergente, con slip rate di deformazione stimato tra 1.5 mm/yr [Burrato et al., 2009] e 1.8-2.0 mm/yr [Benedetti et al., 2000]. Scopo del progetto OMBRA è quello di studiare alcune questioni ancora aperte e scientificamente controverse. Ci si chiede come questi eventi storici forti possano integrarsi nel contesto della debole sismicità di fondo osservata recentemente. Inoltre è interessante capire come una velocità di placca relativamente alta possa accomodarsi nel pattern regionale e inoltre quali strutture tra l’anticlinale e il fronte alpino possano essere potenzialmente attive.
