    Description: Negli ultimi anni l'incremento di fenomeni di sprofondamento nel territorio di Roma Capitale e nella sua area metropolitana costituisce un rischio sempre maggiore per la popolazione e per le infrastrutture. Il verificarsi di questi eventi è in gran parte dei casi connesso alla presenza di sistemi caveali di origine antropica e diversa età e funzione. Il presente studio ha permesso di perfezionare un protocollo speditivo di utilizzo integrato di alcuni metodi geofisici (microgravimetrico, georadar e sismico) funzionale all’individuazione di cavità nel sottosuolo, che permette di mappare dimensioni, distribuzione spaziale e profondità. Tale base informativa risulta imprescindibile per una gestione in sicurezza degli edifici scolastici esistenti e per la progettazione di nuovi interventi.

    Description: gravity study was carried out to identify the geological and structural features of the Middle Aterno Valley, and intramontane depression in the central Appennines, which was targeted to assess the seismic hazard of the city of L’Aquila and surrounding areas, after the Abruzzo 2009 earthquake. Gravity anomalies have been used for the construction of a 3D model of the area, and gravity data for the construction of Bouguer and residual anomaly maps. These data, together with geological surface data allowed for the understanding of the Plio-quaternary tectonic setting of the basins. The study area has been differentiated into different domains with respect to structural and morphological features of different styles of faults. Geology and gravity data show that the local amplification phenomena are due to the fact that the historical center of L’Aquila was built on a coarse breccias (debris-flow deposits with decameter scale limestone blocks) overlying sandy and clayey lacustrine sediments. As these sediments have a low density, gravity prospecting very easily identifies them. Residual anomalies, showing a relative gravity low corresponding to the historical center of L’Aquila, and surrounding areas, indicated that these sediments are up to 250 m-thick. Gravity prospecting also revealed the uprooting of the reliefs which outcrop in the area of Coppito. These reliefs, practically outcrop in the middle of the basin. Here, the gravity anomalies are negative and not positive as would be expected from outcropping geological bedrock.

    Description: Nell’ambito del progetto di microzonazione sismica dell’area aquilana è emersa la necessità di utilizzare la gravimetria in situazioni geologiche complesse e laddove il modello geologico del sottosuolo dell’area non è ben determinato, e soprattutto per definire la profondità e la geometria del substrato geologico sepolto. Si ricorda che questo tipo di indagini non è previsto dagli ICMS (2008). L’obiettivo dello studio gravimetrico è di restituire una carta delle isobate del substrato geologico. Infatti, la prospezione gravimetrica consente, attraverso misure effettuate sulla superficie terrestre, di osservare e interpretare anomalie di gravità prodotte da contrasti laterali non noti di densità tra masse sepolte, e di definire le profondità e gli spessori delle rocce presenti nel sottosuolo. Da tale studio dettagliato si possono ottenere diverse informazioni del sottosuolo, sia qualitative che quantitative che serviranno a programmare in modo più corretto possibile le successive indagini geofisiche previste dagli ICMS nella fase di secondo e terzo livello.

    Description: Preliminary gravity results are presented in a study carried out in the "Il Laghetto" area and in the surroundings. This area is situated in the NNE of Rome suburb near Via Palombarese among Guidonia town, which is in the east side, Mentana town, which is in the west side and S.Angelo Romano town, which is in the north side. From a morphological point of view "Il Laghetto" area is a subcircular hole, 30 metres deep and 140 metres wide at the top and 120 metres wide at the bottom. In the 30 last years this place has been affected by anthropic buildings. The first gravity data carried out in this place show that Bouguer and Residual anomalies are qualitatively similar, indicating a gravity minimum approximately in the hole’s center.The surrounding area is characterized by two different fluvial trends; one of these is oriented in the N-S side and the other one in the NW-SE side. More specifically, these fluvial trends could indicate a general profile of tectonic structures in this area. At the same time, neither faults nor tectonic structures nor other geologic elements are evident in this place. This is a result of geologic rocks outcrop: Plio-Pleistocene clayes deposits, high-potassium volcanic rocks of the Roman Comagmatic Province (products erupted during the first Tuscolano-Artemisio caldera stage, Middle-Upper Pleistocene) and recent continental deposits.In order to recognize other morphological holes, which should be re-covered by some metres thick recent continental deposits in this area, it has been thought to carry out gravity survey on a particular area situated in the north side of "Il Laghetto" area: the Fosso di Marco Simone.

    Description: Historical research has shown that Terracina (Latina, Latium) played a fundamental role in the maritime and land traffic since before the foundation of the colony. The settlement was established where the organized system of maritime, land, coastal, and fluvial transport had the most ideal conditions to constitute an important commercial crossroads, apparently since the beginning of recorded history. In order to reconstruction the buried archaeological structures attributed to the ancient Roman port, traditionally attributed to Traiano, in the current area of the harbour of Terracina, it was carried out a gravity survey, more than 380 gravity stations. This method enables to recognize the cavity and the structures of the buildings underground through the results of variations density in the subsoil. In the residual gravity anomaly map a series of positive anomalies are visible which confirm the round structures and the pier of the buried foundations of the Imperial harbour. Unfortunately, little remains of the functioning facilities of the harbour’s activities. The modern construction of the harbour, in fact, has to be developed around the new inhabitable commercial area, know today as Terracina Bassa or Borgo alla Marina. It had to be developed with a modern infrastructure of a harbor area, as in the construction of the rooms for storage of goods, warehouses, as well as for the thermal baths, hotels and amphitheatre. Furthermore, there are always the positive anomalies that characterize the area to the north-east of “Montone” hill where archaeological remains are easily visible near Via Lungolinea Pio VI. A large negative anomaly is situated in correspondence with “Montone”. Gravity information shows an average density of the hill approximately 1.10 g/cm3, notably less than the recorded data relative to dry sand, approximately 1.6 g/cm3. The low value founds hits at the possibility of an “emptiness” in the subsoil of “Montone” hill, attribuiting to the possible ancient buried constructions (the rooms for storage of goods and warehouses). The sandy covering would therefore be natural from aeolian origins, like all the dunes present along this area near the southern coast of Latium. This hypothesis is in contrast to the information recorded from 1600 that attributes the formation of the reliefs accumulated to sand having been dredged up from the harbour.

    Description: Systematic analyses of the tectonic structures of the Plio-Pleistocene units and MesoCenozoic deposits of the Acque Albule Basin, 1Okm East of Rome between Mount Soratte, Cornicolani Mts. and Lucretili Mts. in central Italy, show a complex tectonic framework. A gravity survey was carried out to identify the geological and structural features of the basin. Gravity anomalies have been used for the construction of a 3D model of the area, and gravity data for the construction of Bouguer and residual anomaly maps. These data, together with geological surface data, allowed for the understanding of the Plio-quaternary tectonic setting of the basin. The trend of anomalies, around the two relative gravity lows. Here, two relative gravity lows are separated by a wide saddle, located near the Casale Battisti (Guidonia). This plain are characterized by the presence of some collapse phenomena of different types and/or origins. The majority of these collapses are aligned along regional master and seismogenetic faults. Over the last 1O years several collapse phenomena risk area have been detected by micro- gravity survey in Acque Albule plain areas. In this paper only Lago delle Tartare is considered. Both microgravity and seismic tomography data have been proposed in order to better under- stand the underground geological features of the morphological depression.

    Description: In this work we characterize the microgravity and seismic response of archaeological remains of Roman Amphitheater of Durres situated on the Adriatic coast in Albania. Geophysical methods have proven to very useful to archaeologists in order to detect, map and study the characteristics of different types of objects and structures in the subsurface. These methods allow the evaluation of their conservation state, the identification of different construction phases and zones disturbed by agricultural activities or plundering. Moreover the investigation of geological deposits and buried landforms is useful for generating paleo-environmental information. The surveys indicate the presence of walls of various sizes and width having different preservation states and series of underground tunnels used to house animals and slaves as construction of the Colosseum. Structures sizes are comparable to those of medium size in the other amphitheatres found in the Mediterranean basin. Our study focused on southern sector of the site. Archaeological excavations were carried out at this area, with only one house being dug in each sector. The archaeological excavations carried out in this sector show evidence the comparison between the seismic and gravity data. According to the historical investigations, these sectors should correspond to settlers houses, but there is no information about the internal organization of the houses and their occupation before the abandonment of the colony. The building ended to be used for entertainment in the early Middle age. It was later reused for such purposes as housing, workshops, quarters for religious order, a fortress, a quarry, and a Byzantine shirne.

    Description: L’Insula del Centenario IX, 8 è stata oggetto di una serie di indagini geofisiche per individuare le strutture sepolte al di sotto della superficie topografica. Di seguito verrà illustrato il contesto geologico in cui è situata l’Insula, poi il metodo utilizzato, la prospezione ed i risultati che si sono ottenuti. Vengono illustrati il concetto e la storia della gravimetria. Il metodo gravimetrico viene utilizzato per delineare variazioni di densità nel sottosuolo e quindi individuare strutture o cavità che abbiano un sufficiente contrasto di densità. Tale metodo è molto usato nella ricerca geologica di base per studi di geologia strutturale e nella ricerca petrolifera. Nell’ultimo decennio con lo sviluppo dei microgravimetri, il metodo microgravimetrico è stato applicato anche in campo archeologico per poter dettagliare strutture murarie o cavità presenti nell’immediato sottosuolo. Lo studio geofisico integrato, microgravimetria e georadar, dell’Insula del Centenario ha fornito numerose informazioni per indirizzare scavi e ricerche.
