    La Rete Integrata Nazionale GPS (RING): stato dell'arte a due anni dalla nascita (2008)
    Details
    Publication Date: 2017-04-04
    Description: Le reti permanenti GPS costituiscono una importante risorsa per una serie di studi tecnologici e scientifici. La carenza di conoscenze in studi di tettonica attiva, che comprendono anche la parte di sismologia come l'accumulo di deformazione sulle faglie, è stata a lungo frenata dalla mancanza di reti permanenti GPS sufficientemente dense distribuite su tutto il territorio nazionale. In particolare, la definizione di una placca Adriatica e la sua terminazione meridionale sono ancora materia di dibattito (Oldow et al., 2002; Battaglia et al. 2004). Inoltre, di recente, alcuni importanti lavori (Hollenstein, et al. 2004; D'Agostino and Selvaggi; Serpelloni et al. 2005) hanno mostrato che valori di deformazione molto più alti di quanto si pensava prima sono stati effettivamente riscontrati nella nostra regione e che solo l'uso di una rete densa di stazioni, quindi di un campionamento ad alta densità nelle aree dove sono maggiori le velocità relative, permette di osservare in modo corretto il rilascio, o accumulo, di deformazione. Infine, il contributo della geodesia alla sismologia sta diventando sempre più importante sia nella definizione del rilascio cosismico durante un terremoto e sia nell'osservazione e modellazione dell'accumulo intersismico di deformazione elastica su faglie attive. Da qualche anno, l'Istituto Nazionale di Geofisica e Vulcanologia (INGV) ha impiegato notevoli risorse e sforzi per rispondere a tali temi scientifici. Selvaggi et al. (2006) hanno gettato le basi e mostrato i primi sviluppi di una rete GPS permanente, la Rete Integrata Nazionale GPS (RING), creata con l'obiettivo di dare un forte contributo scientifico ai temi sopra citati La rete RING (Fig. 1a), nella sua completezza, rappresenta ad oggi non solo un punto di riferimento per studi di carattere scientifico ma anche una robusta infrastruttura tecnologica e informatica per l'archiviazione dei dati GPS per diverse altre reti locali e regionali (Regione Puglia, Regione Friuli, Leica Geosystems). Tali reti, contribuiscono quotidianamente all'acquisizione, all'interno di un server, di dati per un totale di oltre 300 stazioni distribuite sul territorio nazionale (Fig. 1b). Se, poi, si considera anche l'aspetto del processamento dei dati GPS, l'utilizzo di dati GPS appartenenti ad altre reti (locali, regionali o anche esterne al territorio italiano) fa sì che ogni analista utilizzi i dati, in media, di circa 650 stazioni GPS permanenti al giorno.

    A first look at the Gargano (southern Italy) seismicity as seen by the local scale OTRIONS seismic network (2014)
    Details
    Publication Date: 2021-12-17
    Description: OnApril 2013,alocal scale seismic network,namedOTRIONS, composed of twelve short period (1 Hz) three component seismometers, has been located in the northern part of the Apulia (Southern Italy). At each station, the acquisition systemallows the recording of data in situ and their real time transfer toa seismic laboratory located at the Dipartimento di Scienze della Terra e Geoambientali of Università di Bari "Aldo Moro". The preliminary real time detection and localization of the events is automatically realized by using the SeisComp3 software. In the first two months of data acquisition, the network recorded about one hundred low magnitude (ML〈2) earthquakes. In that follows,wepresent the results of a study aimed at investigating the crustal structure of the Gargano promontory. To this aimweanalyzed the seismic events recorded in the area by the “Istituto Nazionale di Geofisica e Vulcanologia” (INGV) in the period 2006-2012 and the seismic events recorded by the OTRIONS network in the first two months of acquisition (march and april 2013). From the inversion of P and S travel times of INGV events we inferred a preliminary 3-layer Vp velocity model. The Moho is located at a depth of 27-30 km, in agreement with previous studies. A linearized inversion scheme that uses Velest (Kissling et al., 1994), allowed us to infer a 1D velocity model from the joint inversion of INGV and OTRIONS datasets of P and S travel times. On the whole, the number of earthquakes recorded by the OTRIONS seismic network is higher than 1200 in the period april,2013-march,2014.

    A first look at the Gargano (southern Italy) seismicity as seen by the local scale OTRIONS seismic network (2014)
    Details
    Publication Date: 2021-12-17
    Description: On April 2013, a local scale seismic network, named OTRIONS, composed of twelve short period (1 Hz) three component seismometers, has been located in the northern part of the Apulia (southern Italy). In the first two months of data acquisition, the network recorded about one hundred very small (ML〈2) magnitude earthquakes. A three-layer 1D VP velocity model was preliminarily computed, using the recordings of earthquakes occurred in the area in the period 2006-2012 and recorded by the national seismic network of INGV (Istituto Nazionale di Geofisica e Vulcanologia). This model was calibrated by means of a multi-scale approach, based on a global search of the minimum misfit between observed and theoretical travel times. At each step of the inversion, a grid-search technique was implemented to infer the elastic properties of the layers, by using HYPO71 to compute the forward models. In a further step, we used P and S travel times of both INGV and OTRIONS events to infer a minimum 1D VP velocity model, using a classical linearized inversion approach. Owing to the relatively small number of data and poor coverage of the area, in the inversion procedure, the VP/VS ratio was fixed to 1.82, as inferred from a modified Wadati diagram. The final 1D velocity model was obtained by averaging the inversion results arising from nine different initial velocity models. The inferred VP velocity model shows a gradual increase of P wave velocity with increasing the depth. The model is well constrained by data until to a depth of about 25-30 km.
