TL;DR: In this paper, the authors presented a tectonic-geomorphological map (scale 1:40,000) of the Abruzzo Apennines, which is the result of a morphotectonic investigation of the middle Aterno River valley, which includes the area from the western L'Aquila-Coppito basin to the Paganica-San Demetrio basin and to the Castelnuovo-Civitaretenga basin.
Abstract: After the 6 April, 2009 normal faulting L'Aquila earthquake (Mw 6.3), the attention of many scientists was drawn to the Abruzzo Apennines. Until that time few studies had addressed the geomorphological and morphotectonic features of this area and none to extensive geomorphological mapping.The tectonic-geomorphological map (scale 1:40,000) presented in this work is the result of a morphotectonic investigation of the middle Aterno River valley, which includes the area from the western L'Aquila-Coppito basin (to the northwest) to the Paganica–San Demetrio basin and to the Castelnuovo–Civitaretenga basin (to the southeast).The map is implemented within a GIS environment by means of: DEM and map-based cartographic analysis and morphometry of orography and hydrography (raster and vector data scale 1:25,000, 10 m grid DEM), photogeological analysis (scale 1:10,000), structural geomorphological field mapping (scale 1:10,000), basin fill geometry analysis (geophysical and borehole investigations) and tectonic–geom...

Post-Wildfire Landslide Hazard Assessment: The Case of The 2017 Montagna Del Morrone Fire (Central Apennines, Italy)

TL;DR: In this paper, a post-wildfire landslide hazard assessment, applied to the 2017 Montagna del Morrone fire, was performed using a heuristic or expert-based approach, integrated using GIS technology.
Abstract: This work focused on a post-wildfire landslide hazard assessment, applied to the 2017 Montagna del Morrone fire. This wildfire increased the possibility of landslides triggering, as confirmed by the occurrence of a debris flow, triggered by an intense, short duration rainfall event in August 2018. The study area was investigated through a detailed analysis incorporating morphometric analysis of the topography and hydrography and geomorphological field mapping, followed by the landslide hazard assessment. In detail, the analysis was performed following a heuristic or expert-based approach, integrated using GIS technology. This approach led to the identification of five instability factors. These factors were analyzed for the construction of thematic maps. Hence, each factor was evaluated by assigning appropriate expert-based ranks and weights and combined in a geomorphology-based matrix, that defines four landslide hazard classes (low, moderate, high, and very high). Moreover, the morphometric analysis allowed us to recognize basins prone to debris flows, which, in relevant literature, are those that show a Melton ratio of >0.6 and a watershed length of <2.7 km. Finally, all the collected data were mapped through a cartographic and weighted overlay process in order to realize a new zonation of landslide hazard for the study area, which can be used in civil protection warning systems for the occurrence of landslides in mountainous forested environments.

TL;DR: In this article, the main intermontane basins have been correlated along a SW-NE transect, comparing sedimentary sequences and morphotectonic features, the evidence of local tectonics and uplift pulses, and the main features of the drainage systems, in order to outline the drainage changes occurred during the Quaternary in the Central Apennines chain.
Abstract: The Central Apennines chain (Central Italy) is an asymmetric NW–SE thrust belt, NE verging, that has developed since the Neogene. The present landscape is made up of alternating calcareous ridges, valleys on pelitic arenaceous bedrock, as well as wide intermontane basins filled by Quaternary continental deposits. The chain is characterised at high elevation by glacial and isolated patches of dissected karst relict landscapes elevations, and by slope landforms, alluvial fans and fluvial landforms within valleys and intermontane basins; in the latter ancient lacustrine deposits are preserved. Intermontane basins, valley and drainage systems, and relict landscapes are affected by active geodynamic processes resulting in regional uplift, extensional faulting and local subsidence, and by Quaternary climate fluctuations. In this work, the main intermontane basins have been correlated along a SW–NE transect, comparing sedimentary sequences and morphotectonic features, the evidence of local tectonics and uplift pulses, and the main features of the drainage systems, in order to outline the drainage changes occurred during the Quaternary in the Central Apennines chain. Along a SW–NE swath profile, min, mean and max topography elevations, the basins’ min elevation, the elevation of the main karst landforms, and the Pleistocene uplift have been compared. These correlations and comparisons allowed us to provide a further contribution to the understanding of the Quaternary evolution of the drainage systems and the landscape of the Central Apennines chain.

TL;DR: In this article, resistivity images were obtained across the Paganica-San Demetrio Basin, bounded by the 2009 L'Aquila Mw 6.1 normal-faulting earthquake causative fault (central Italy).
Abstract: Three 2-D Deep Electrical Resistivity Tomography (ERT) transects, up to 6.36 km long, were obtained across the Paganica-San Demetrio Basin, bounded by the 2009 L'Aquila Mw 6.1 normal-faulting earthquake causative fault (central Italy). The investigations allowed defining for the first time the shallow subsurface basin structure. The resistivity images, and their geological interpretation, show a dissected Mesozoic-Tertiary substratum buried under continental infill of mainly Quaternary age due to the long-term activity of the Paganica-San Demetrio normal faults system (PSDFS), ruling the most recent deformational phase. Our results indicate that the basin bottom deepens up to 600 m moving to the south, with the continental infill largely exceeding the known thickness of the Quaternary sequence. The causes of this increasing thickness can be: (1) the onset of the continental deposition in the southern sector took place before the Quaternary, (2) there was an early stage of the basin development driven by different fault systems that produced a depocentre in the southern sector not related to the present-day basin shape, or (3) the fault system slip rate in the southern sector was faster than in the northern sector. We were able to gain sights into the long-term PSDFS behaviour and evolution, by comparing throw rates at different timescales and discriminating the splays that lead deformation. Some fault splays exhibit large cumulative throws (>300 m) in coincidence with large displacement of the continental deposits sequence (>100 m), thus testifying a general persistence in time of their activity as leading splays of the fault system. We evaluate the long-term (3–2.5 Myr) cumulative and Quaternary throw rates of most of the leading splays to be 0.08–0.17 mm yr−1, indicating a substantial stability of the faults activity. Among them, an individual leading fault splay extends from Paganica to San Demetrio ne’ Vestini as a result of a post-Early Pleistocene linkage of two smaller splays. This 15 km long fault splay can explain the Holocene surface ruptures observed to be larger than those occurred during the 2009 L'Aquila earthquake, such as revealed by palaeoseismological investigations. Finally, the architecture of the basin at depth suggests that the PSDFS can also rupture a longer structure at the surface, allowing earthquakes larger than M 6.5, besides rupturing only small sections, as it occurred in 2009.

TL;DR: In this paper, a 3D physics-based numerical simulation of the 2009, April 6, L’Aquila earthquake (central Italy) is presented, based on improved models of the Aterno river basin geology and source kinematics.
Abstract: In this paper, we present 3D physics-based numerical simulations, in the near-source region at the regional scale, of the 2009, April 6, L’Aquila earthquake (central Italy), based on improved models of the Aterno river basin geology and source kinematics. The simulations were carried out by an open-source code, SPEED, based on a discontinuous Galerkin spectral element method. The numerical mesh of the Aterno basin was built on a detailed subsurface geological model and on the evaluation of the dynamic properties of the soils. The source model was selected among the kinematic solutions available in the literature as the one that fits best the near-source observations. Broadband ground motions were then generated through a hybrid method, combining 3D low frequency waveforms with high-frequency stochastic synthetics. To provide an example of application as seismic input to earthquake engineering analyses in the time domain, results of this approach were used for 2D site response analyses at Castelnuovo, a village severely damaged by the earthquake, and in the neighborhood of which no seismic record was available. SPEED simulation satisfactorily reproduces the recorded accelerograms in the frequency range 0.1–0.7 Hz. The site response analysis at the local scale shows that the amplification of the hill is more significant at its natural frequency, due to topographic and stratigraphic factors, than at the peak of the seismic input simulated by SPEED, that is at about 3 s along the fault-normal component. The presented application supports the conclusion that 3D physics-based numerical simulations do have the potential to become an alternative for determination of input ground motion for earthquake engineering analyses, especially for those scenarios for which real records are not available.

TL;DR: In this paper, the authors use the central Italian Apennines to determine the controls on drainage network evolution and its impact on transient landscape evolution and basin stratigraphy, and conclude that consecutive drainage integration events produce discrete waves of river incision and terrace formation.

TL;DR: In this article, a method for extracting topographic indices of longitudinal profi le shape and character from digital topographic data is described, which can then be used to delineate breaks in scaling that may be associated with tectonic boundaries.
Abstract: Empirical observations from fl uvial systems across the globe reveal a consistent power-law scaling between channel slope and contributing drainage area. Theoretical arguments for both detachmentand transport-limited erosion regimes suggest that rock uplift rate should exert fi rst-order control on this scaling. Here we describe in detail a method for exploiting this relationship, in which topographic indices of longitudinal profi le shape and character are derived from digital topographic data. The stream profi le data can then be used to delineate breaks in scaling that may be associated with tectonic boundaries. The description of the method is followed by three case studies from varied tectonic settings. The case studies illustrate the power of stream profi le analysis in delineating spatial patterns of, and in some cases, temporal changes in, rock uplift rate. Owing to an incomplete understanding of river response to rock uplift, the method remains primarily a qualitative tool for neotectonic investigations; we conclude with a discussion of research needs that must be met before we can extract quantitative information about tectonics directly from topography.

TL;DR: In this article, the location and geometry of the main shock and aftershocks recorded by permanent and temporary networks are presented. But the authors focus on the distribution of the aftershock events, 712 selected events with M L > 2.3 and 20 with M l > 4.0.
Abstract: [1] A M w 6.3 earthquake struck on April 6, 2009 the Abruzzi region (central Italy) producing vast damage in the L'Aquila town and surroundings. In this paper we present the location and geometry of the fault system as obtained by the analysis of main shock and aftershocks recorded by permanent and temporary networks. The distribution of aftershocks, 712 selected events with M L > 2.3 and 20 with M L > 4.0, defines a complex, 40 km long, NW trending extensional structure. The main shock fault segment extends for 15―18 km and dips at 45° to the SW, between 10 and 2 km depth. The extent of aftershocks coincides with the surface trace of the Paganica fault, a poorly known normal fault that, after the event, has been quoted to accommodate the extension of the area. We observe a migration of seismicity to the north on an echelon fault that can rupture in future large earthquakes.
