The earthquake that struck L’Aquila on April 6 2009 directly affected the Gran Sasso aquifer. Co-seismic and post-seismic changes in groundwater discharge and in hydrochemistry, possibly induced by the earthquake, were observed. Spot and monitoring
measurements of the spring discharge, of water table level and of the main physico-chemical parameters of spring waters (T, pH, electrical conductivity, major ions and 222Rn) were thus carried out to determine the effects of the L’Aquila earthquake
The aim of this study is the definition of the geometry and structural style of the extensional fault system involved during the L’Aquila 2009 seismic sequence. The surface tectonic setting of the late Quaternary faults in the epicentral areas (i.e
. The seismic sequence reactivated 4 well-distinguished fault sources differing in geometry, size and the degree of involvement. The L’Aquila 2009 seismic sequence did not reactivate the entire surface of the involved faults. Nevertheless, on the basis of other
Field investigations performed in the epicentral area within the days following the April 6, 2009 L’Aquila earthquake allowed several researchers to detect evidence of coseismic ground rupturing. This has been found along the Paganica Fault and next
The intermediate-field hydrological response to the 6th April 2009 L’Aquila earthquake has been studied using groundwater level data that were recorded by 6 piezometers in the Acque Albule Basin (Tivoli travertine quarry area) and in the Cornicolani
Mountains (Pozzo del Merro shaft). The hydrogeological setting of the Tivoli area is characterised by 2 superimposed aquifers : a deep aquifer in carbonate and a shallow aquifer in travertine. At the time of the L’Aquila earthquake, the groundwater level

A Mw 6.3 earthquake occurred on April 6, 2009 in the Abruzzo region, close to the city of L’Aquila. A soil gas survey (CO2 and CH4 flux measurements, soil gas measurements and collection) has been carried out in an area of 24 km2 (few kilometers far
from L’Aquila city) to investigate the gasbearing properties of local seismogenic faults (Paganica, Bazzano, and Monticchio-Fossa faults) and to locate fracture systems when masked by unconsolidated lithologies. Anomalous values of Rn and CO2 were
This paper presents the results of a continuous monitoring of the surface displacements following the April 6th 2009 L’Aquila earthquake. The AA. considered 3-dimensional displacements measured via Robotized Total Station (RTS) installed the April
period. The results suggest that L’Aquila earthquake post-seismic displacements were dominated by the fault afterslip and/or fault creep, while poroelastic and viscoelastic processes had negligible effects. - (NF)
Following the April 6 2009 L’Aquila earthquake, a great effort has been carried out for seismic microzonation purposes of urban areas in order to evaluate the seismic potential of the main active faults of the epicentral area. This is the case
of the active Mt. Pettino master extensional fault (hereafter PEF) which controls the tectono-sedimentary evolution of western L’Aquila Basin. The investigations were mainly based on a seismic reflection profile orthogonal to the fault strike in its hangingwall
Compte rendu de l'excursion des géographes italiens, dans les Abruzzes en septembre1977. Elle partait de l'Aquila, traversait Assergi, Campo Imperatore (massif du Gran Sasso), la vallée du Tavo, Penne, Francavilla al Mare, Ortana, puis au nord vers
Pescara. Atri, Teramo, Campotosto, avant de revenir à l'Aquila. Le domaine montagneux et littoral a été étudié tant du point de vue géomorphologique qu'humain et économique.
This paper presents the study of some liquefaction features occurred near the Fossa village due to the April 6, 2009 L’Aquila earthquake (Central Italy). The investigation is based on trenching and coring campaigns as well as sedimentological
The analysis of the damage following the 2009 L’Aquila earthquake clearly indicates a strict control of the local geological conditions over the distribution of the effects. This paper illustrates some of the most significant cases of local effects
High-resolution controlled-source seismic tomography across the Middle Aterno basin in the epicentral area of the 2009, Mw 6.3, L’Aquila earthquake (central Apennines, Italy)
Seismic data have been collected along 4 dense wide-aperture profiles, that run SW-NE for a total length of ~6 km in the hangingwall of the Paganica-S. Demetrio Fault, source of the 6th April 2009 L’Aquila normal-faulting earthquake. Seismic
Field surveys performed by different research groups after the April 6, 2009 L’Aquila earthquake identified the occurrence of surface faulting along the Paganica normal fault, the causative seismogenic source of the event.The AA. integrated
This paper was spurred by the 6 April 2009, L’Aquila earthquake. Although the earthquake was not major compared with other catastrophic events, this destructive earthquake led to a thorough review of the geometry – and style, in some instances
This paper deals with the proposal and application of a micromorphological soil development index (MISODI) to paleosols in the L'Aquila-Scoppito basin in order to test its utility in the chronostratigraphy research for Quaternary continental
of the phenomenon. It also refers to the relationship between ecorefugee and internally displaced persons with reference to recent natural disasters (L’Aquila earthquake and Katrina hurricane). Finally, the typology is interpreted from a geopolitical point of view
Several studies carried out previously on the gran Sasso Range and nearby (Monti della Laga) in Province of L'Aquila (Abruzzi, Italy) noted qualitative relationship among the rock fracturing degree, and the farst landforms. This research deals
