We provide a database of the coseismic geological surface effects following the Mw 6.5 Norcia earthquake that hit central Italy on 30 October 2016. This was one of the strongest seismic events to occur in Europe in the past thirty years, causing complex surface ruptures over an area of >400 km2. The database originated from the collaboration of several European teams (Open EMERGEO Working Group; about 130 researchers) coordinated by the Istituto Nazionale di Geofisica e Vulcanologia. The observations were collected by performing detailed field surveys in the epicentral region in order to describe the geometry and kinematics of surface faulting, and subsequently of landslides and other secondary coseismic effects. The resulting database consists of homogeneous georeferenced records identifying 7323 observation points, each of which contains 18 numeric and string fields of relevant information. This database will impact future earthquake studies focused on modelling of the seismic processes in active extensional settings, updating probabilistic estimates of slip distribution, and assessing the hazard of surface faulting.

In the axial zone of the Umbria-Marche Apennines, several fault-bounded intermontane basins (i.e., Colfiorito, Norcia, Castelluccio, and Leonessa) were generated at the end of Lower Pleistocene. The analysis of the master fault of the basins, the relicts of planation surfaces and the drainage network arrangements, allowed us the improvement of knowledge on the Pleistocene morphotectonic evolution of those basins.\ud Morphometry and geostatistics of the topography have been performed to obtain indexes suitable for assessing the role of faults displacements on the landscape development. Furthermore, a gravimetric analysis realized along some basins has furnished new data on their sedimentary infill. The basins are filled by Pleistocene to Holocene fluvial-lacustrine coarse-grained deposits, and the bedrock consists of Jurassic to Miocene\ud limestone and marls belonging to the Umbria-Marche succession. Several historical and instrumental highly destructive earthquakes occurred in this area: January 14, 1703 (X MCS, M = 6.6); September 19, 1979 (Ms = 5.9, focal depth of 6–8 km); September 26, 1997 (Mw = 6.0, focal depth of 6–8 km). Faults and earthquake focal mechanisms are compatible with a predominant NE–SW extension, but strike-slip and reverse mechanisms have been also documented. The fault activity appears to have had a predominant role in controlling the sedimentation processes inside the intermontane basins, as well as in controlling their Pliocene to Quaternary evolution

Potential evapotranspiration (ET0) is an indicator of great interest for water budget analysis and the agricultural sector. Therefore, the purpose of this study was to make the calculation reliable even if only the temperature data were present. In this research, the ET0 was initially calculated for a limited number of weather stations (12) using the Penman–Monteith method. In some cases, the simplified Penman–Monteith formula was adopted, while in others, as in the case of mountain weather stations, the complete formula was employed to consider the differences in vegetation, deduced from satellite surveys. Subsequently, the ET0 was calculated with the Hargreaves–Samani (HS) formula, calibrating the Hargreaves coefficient, through the spatialization of ET0, by the geostatistical method. The results showed a high reliability of the HS method in comparison with simplified PM (PM) method, and complete Penman–Monteith (cPM) method, with a minimum calibration of the empirical Hargreaves coefficient. In particular, a very good correlation between the results obtained in the mountain environment with the uncalibrated HS method and the cPM method was also observed in this area, while PM showed discordant and much higher results than ET0 compared with the other methods. It follows that this procedure allowed a more accurate estimate of potential evapotranspiration with a view to territory management, both in terms of water resources and the irrigation needs of the vegetation.

The present work aims to establish relationships between shoreline historical variations (close to the river mouths) and slope dynamics on mountain and hilly areas: these are considered as fundamental physiographic units of the Adriatic central Italy. The study deals about the deltaic system of the Chienti river, which is representative of the deltaic systems of the main Marchean rivers. Goal is to recognize possible geomorphological indicators of climatic variations during late Holocene. Debris flows on the Sibillini Mts were analysed and interpreted. Their activation can be associated with: late Pleistocene-early Holocene deglaciation, with regard to the oldest phenomena; agricultural, forestry and grazing activities during the Late Middle Ages, even though evidence of climatic conditioning is also present. Moreover, some important landslide phenomena on the high hilly areas were examined: historical data demonstrated an intense post-Middle Age activity (XVth-XVIIIth centuries) related to the strong rainfall increase as a consequence of climatic worsening.
Dans cette note, sont interprétées quelques formes mineures du paysage physique, utilisables en tant qu'indicateurs géomorphologiques des variations climatiques de l'Holocène supérieur. La création et l'évolution de ces formes sont liées à la circulation superficielle et souterraine d'importantes quantités d'eau. Les processus analysés se réfèrent aux zones représentatives de l'organisation géomorphologique des trois unités physiographiques fondamentales de l'Italie centrale adriatique : les régions montagneuses, la bande péri-adriatique des hautes collines et la plaine côtière.La première zone appartient au massif des Monts Sibyllins, dans l'Apennin central d'Ombrie-Marches. Les sommets dépassent fréquemment 2000 mètres d'altitude et atteignent 2476 mètres au Mont Vettore. Le substrat géologique est formé par la célèbre "succession d'Ombrie-Marches" (Trias supérieur - Aquitanien), constituée d'unités lithostratigraphiques calcaires, marno-calcaires et marneuses. La disposition structurale est caractérisée par des plis à vergence orientale marquée, des chevauchements et des failles normales. Le substrat rocheux est souvent oblitéré par la présence de dépôts morainiques, de dépôts fluvio-torrentiels et d'accumulations d'éboulis stratifiés. Dans cet espace, l'analyse géomorphologiques de détail et les enquêtes historiques approfondies effectuées sur les nombreuses coulées torrentielles, a rendu possible l'établissement des cinématiques fondamentales. L'attribution chronologique probable des phénomènes les plus anciens à la fin du Pléistocène supérieur et au début de l'Holocène, a été établie sur la base des corrélations des dépôts avec les formes alluvionnaires, glaciaires et périglaciaires environnantes. Leur déclenchement est associé à la déglaciation de la fin du Pléistocène - début de l'Holocène. Les phénomènes plus récents sont en grande partie attribués à l'époque médiévale et post-médiévale. Les sources historiques témoignent de la récurrence ...
