Abstract. The potential of coupling soil moisture and a Universal Soil Loss Equation-based (USLE-based) model for event soil loss estimation at plot scale is carefully investigated at the Masse area, in central Italy. The derived model, named Soil Moisture for Erosion (SM4E), is applied by considering the unavailability of in situ soil moisture measurements, by using the data predicted by a soil water balance model (SWBM) and derived from satellite sensors, i.e., the Advanced SCATterometer (ASCAT). The soil loss estimation accuracy is validated using in situ measurements in which event observations at plot scale are available for the period 2008–2013. The results showed that including soil moisture observations in the event rainfall–runoff erosivity factor of the USLE enhances the capability of the model to account for variations in event soil losses, the soil moisture being an effective alternative to the estimated runoff, in the prediction of the event soil loss at Masse. The agreement between observed and estimated soil losses (through SM4E) is fairly satisfactory with a determination coefficient (log-scale) equal to ~ 0.35 and a root mean square error (RMSE) of ~ 2.8 Mg ha−1. These results are particularly significant for the operational estimation of soil losses. Indeed, currently, soil moisture is a relatively simple measurement at the field scale and remote sensing data are also widely available on a global scale. Through satellite data, there is the potential of applying the SM4E model for large-scale monitoring and quantification of the soil erosion process.

Morphofunctional Analysis

A new paracomatulid crinoid, Tiburtocrinus toarcensis gen. et sp. nov., is described from the Lower Jurassic of Tivoli (central Apennines, Italy). This type of stemless crinoids has never previously been recorded in Italy, and this report bridges a significant gap. Morphofunctional analysis of the radial facets suggests that Tiburtocrinus toarcensis gen. et sp. nov. may have been a crawling paracomatulid, very different from other paracomatulids that probably swam.

Burial Rite

At the date of about 1000 B.c., that is to say a little after the A beginning of the Iron Age and two centuries before any effective colonization by the Etruscans coming from Asia Minor, northern and central Italy may be partitioned into five distinct spheres of civilization. For convenience of treatment I shall assume that each of these spheres represents a comparatively homogeneous people, passing over the question whether there may not have been submerged minorities of some local importance. And I shall give each of these five peoples, or nations as they may not unfairly be called, a conventional name of geographic derivation, to avoid the endless and futile controversies as to tribal nomenclature. As the accompanying map therefore will show the north-west is occupied by the Comacines, part of Venetia by the Atestines, the Bolognese region by the northern Villanovans, Tuscany and part of Latium by the southern Villanovans. East of the Apennines, from Rimini to Aufidena, the Adriatic coast and the central Apennines were held by the Picenes, who must be understood for this purpose to include some of the tribes known to history as Samnites in addition to a small number of Umbrians. The first four of these nations were related by more or less close ties of kinship and practised the same burial rite of cremation, but the Picenes were of wholly different origin and used only the rite of inhumation. Of the Ligurians, occasionally mentioned by classical writers as occupying the coast of the Italian Riviera, it is impossible to say anything as they have left no remains by which their civilization in the Iron Age can be judged.

Extensional Collapse

<p>Post-orogenetic extensional/gravitational collapse events constitute a relatively poorly understood tectonic process, which is responsible for the quick and effective dismantling of the thickened crust and topographic bulge of fold-and-thrust belt edifices. These events are also responsible for the accumulation of very thick post-orogenetic successions and, in case of active extension, may trigger moderate to strong earthquakes resulting in obvious seismic hazards (e.g., the 1915 Mg 7.0 Fucino earthquake in Central Italy, which caused 30,000 victims)</p><p>Here, we combine seismic interpretation coupled with well analyses, basin modelling and a thorough literature review, in order to compare an ancient and a modern example of study areas subject to post-orogenetic collapse. The Devonian-age Old Red Sandstones of north-western Europe and ?Plio-Quaternary fill of the Fucino intramontane extensional basin in the central Apennines (Italy) share several stratigraphic, depositional and tectonic characteristics. Both are characterized by remarkably similar seismic-stratigraphic architecture (with syn-depositional half-grabens) and maximum thickness of >1,500 metres. In the Fucino, the border faults associated to the main tectonic depocentres achieved maximum throw rates of 1,000-1,400 mm/kyr.</p><p>Both units comprise thick continental siliciclastic successions, dominated by lacustrine and alluvial to fluvio-deltaic facies. The facies architecture reveals a progressive transition from localized, fault-bounded depocentres to transgressive lacustrine successions in wider basins that are less reliant on the sole fault-driven subsidence. The studied units were deposited due to high and quick tectonic subsidence which took place very shortly after the end (or during?) of crustal shortening processes (respectively Caledonian and Apenninic orogenesis) and in a post-orogenic collapse context.</p><p>In both study areas, the sedimentation of the thick continental units are intimately associated to a polyphase inversion tectonics, with pre-existing inherited deep-seated discontinuities affected, in places, first by a positive and subsequently by a negative reactivation during the extensional collapse. A further element common in the two study areas, is a strike-slip or oblique tectonics occurring during or immediately prior to the extensional collapse achieved by the normal faulting. This has been interpreted as a consequence of the gradual rotation of the stress vectors around their axes, culminating in the relaxation of the horizontal compressive stress and the onset of the post-orogenetic extensional/gravitational collapse process itself. For example, in the Fucino Basin, maximum Plio-Quaternary sediment thicknesses of >1700 m occur in two tectonic depocentres, situated respectively to the north and east of the basin. In contrast, the south-eastern striking dip-slip border faults bounding the eastern edge of the Fucino show maximum slip rates in the Lower-Middle Pleistocene, with evidence (e.g., Gioia dei Marsi) for a very recent activity, possibly linked with the 1915 seismic event.</p><p>The study of post-orogenic extensional collapse by comparison of ancient and recent basins suggest that in these settings poly-phase tectonic inversion commonly occurs and promote multiple reactivation of inherited zones of weakness. The comprehension of the common and dissimilar features, may be fundamental to better understand the mechanism and evolution of post-orogenic chain reworking and for natural resources and geological hazards assessment, including earthquakes. The coupled analysis of an ancient and recent example enables just that.</p>

Agricultural Organization

The agricultural organization that has long characterized the Central Italian hills, the mezzadria system of share-farming, is today ‘in crisis’. Overtly, the crisis is manifested in an increasing antagonism between landlords and peasants, large-scale withdrawal of peasants from the system, and political agitation directed towards it.

<p>The M=6.0 earthquake that struck central Italy at 01:36 UTC (Universal Time Coordinated) on August 24, 2016, marked the beginning of a long, still-ongoing seismic sequence, which culminated in the Mw 6.5 event at 06:40 UTC on October 30, 2016, while this volume was already in preparation, and reactivated again when this preface was almost complete. This dramatic seismic sequence, which on January 18, 2017, released four additional events of M between 5.0 and 5.5 in a few hours, caused 298 casualties, hundreds of injuries, and the practically total destruction of several villages across a wide area of the central Apennines, covering the Italian Regions of Lazio, Umbria, Marche and Abruzzo. In particular, the historical village of Amatrice was completely destroyed. [...]</p>
