    Description: In questo lavoro si presentano i risultati di uno studio sulle caratteristiche del rumore sismico in prossimità del rilevatore di onde gravitazionali VIRGO (Cascina, Pisa), con particolare riferimento alle vibrazioni associate all’azione di un vicino parco eolico. La valutazione delle componenti spettrali del rumore verosimilmente indotte dagli aerogeneratori è stata effettuata mediante (i) Misure dirette alla base di una turbina, (ii) Correlazione fra le ampiezze spettrali del rumore e la velocità del vento; (iii) Determinazione delle proprietà direzionali da misure multicanale, (iv) Misura dell’attenuazione del segnale con la distanza dal parco eolico. Il disturbo provocato dagli aerogeneratori è particolarmente energetico alla frequenza di 1.7 Hz e, in particolari condizioni, è stato osservato fino a distanze di 11 km dal Parco Eolico. Il decadimento spaziale delle ampiezze ha un andamento complesso, che può essere interpretato in termini di una combinazione fra onde superficiali e onde di volume rifratte ad un’interfaccia profonda (~800 m) fra i sedimenti plio-pleistocenici ed i calcari Miocenici. La risposta locale nei dintorni dell’interferometro è stata investigata utilizzando la tecnica dei rapporti spettrali H/V. Si sono così evidenziate due bande di amplificazione imputabili ad effetti di risonanza legati alla geologia a scala locale: il primo intorno alla frequenza di 0.35 Hz, il secondo fra 0.7 e 2.0 Hz. Entrambi i picchi risultano essere essenzialmente omogenei in tutta l’area di studio, a conferma della sostanziale uniformità della struttura geologica.

    Description: According to the U.S. Geological Survey’s Earthquake Hazards Program, a seismic swarm is “a localized surge of earth- quakes, with no one shock being conspicuously larger than all other shocks of the swarm. They might occur in a variety of geologic environments and are not known to be indicative of any change in the long- term seismic risk of the region in which they occur” (http://vulcan.wr.usgs.gov/Glossary/ Seismicitydescription_earthquakes.html). The definition reveals how little is actually known about seismic swarms. For example, could certain seismic settings be more prone to swarms? Could a fault zone prone to large energetic earthquakes release part of its stress through seismic swarms? Do swarms keep hazards in balance, or could their onset increase hazards? To gain insight into the nature of seismic swarms in nonvolcanic areas and to better understand their influence on seismic hazards, the Istituto Nazionale di Geofisica e Vulcanologia (INGV) and the German Research Centre for Geoscience (GFZ) began a combined research project within the framework of the Network of European Research Infrastructures for Earthquake Risk Assessment and Mitigation (NERA; see http:// www.nera-eu.org/). The project focused on monitoring swarm activity occurring in the Pollino range in Southern Apennines, Italy.

    Description: La Valtiberina è da alcuni anni una delle principali aree dell'Appennino Centro-Settentrionale sottoposta ad indagini mirate alla definizione della geometria del bacino e alla descrizione in termini di geometria e meccanismo della faglia AltoTiberina, principale responsabile dell'attività sismica dell'area. Al fine di contribuire con dati sismometrici alla ricostruzione della risposta sismica del bacino, nella seconda metà del 2005 è stato realizzato un esperimento temporaneo consistito nell'installazione di un array lineare di 8 stazioni sismiche fra Sansepolcro e Anghiari. L'array era disposto lungo una direzione NE-SW, approssimativamente ortogonale all'asse della valle per una lunghezza di circa 8 km con una spaziatura fra le stazioni di circa 1 km. Le stazioni sismiche, equipaggiate con sismometri Lennartz LE3D-5s e Guralp CMG40T accoppiati a sistemi di acquisizione Reftek 130 e Reftek 72A/07, hanno acquisito in continua per circa 5 mesi (da Maggio 2005 a Novembre 2005), registrando alcune centinaia di eventi sismici locali, regionali e telesismi.

    Description: The Larderello geothermal field is located ca. 100 km southeast of Florence, in the northern part of a volcanic zone that extends along the Italian Tyrrhenian coast. Geophysical investigations in the area suggest a crustal thinning and an injection of hot material from the upper mantle into the crust.

    Description: The merits of a seismic array for signal detection and event location are beyond question. The superior signal detection capability is obtained by beamforming and estimating backazimuth and slowness of the seismic wave field by f-k analysis or plane-wave fit gives the parameters for signal classification and event location.
