Topic 5 - Geology, geomechanics and infrastructures
The Montaguto earth flow is one of the most recent landslides involving infrastructure in Southern Italy. It has been periodically active during the last 70 years. This paper provides a description of the main phases in the earth flow activity and its effects on an important Italian national road and railroad tract. The most important earth flow reactivations occurred in 2006 and 2010, when the “SS-90” National Road and the “Benevento-Foggia” tract of the National Railroad, which both connect the ea

Among the types of instability, which vary in terms of typology, evolution and dimension, rock falls represent a constant hazard for structures, buildings and the population, because of their extreme speed. Rock falls in central Italy (Abruzzo Region) occur within the chain area, at the junction between the chain area and the piedmont and between piedmont hills and coastal sectors with wide coastal cliffs. This work focuses on the multidisciplinary analysis of rock falls affecting fault homocline ridges a

With increasing awareness of geological risks, the study of rocky slopes plays a key role in the Earth Sciences, especially in areas of high vulnerability due to the presence of human settlement. The present paper describes the stability and runout analyses carried out along the Alta Tambura road, in correspondence with the Guadine village connecting the Massa urban settlement to the Apuan Alps (Tuscany, Italy). The integration among various types of survey and analytical methodologies allowed for the appli

Rock avalanches dropping into a fjord or lake, initiating displacement waves or damming narrow valleys, are severe hazard scenarios in glacial overprinted mountain areas and have strong influence on the quaternary valley development. Several investigations show, that the collapse of a rock avalanche increases the probability for prospective similar events at the same rock slope. Moreover, data for the Storfjord area in Western Norway indicates that catastrophic rockslides were more frequent during late Plei

In the Astico Valley (Venetian Pre Alps, north east Italy) a rockslide of approximately 10x106 m3 occurred in conjunction with the Verona earthquake (03.01.1117, I0 IX MCS, M 7.0). The rockslide seems to have been favoured by the downhill dip of the carbonate beds and the deposit dammed the narrow valley originating a lake, later emptied by the river incision of the landslide deposit. Upwards of the crown more than 10x106 m3 of rocks are still hanging on the valley. Here we present the results of a prelimi

Laxiwa Hydropower Station is situated on the main reach of the Yellow River, China. The construction was started in October 2001, and impoundment started in March 2009. However, from May 2009, the right-bank slope of the reservoir, about 700 m high and 1000 m wide about 500m far from the dam, was found to be deforming greatly and continuously. Although this slope had been identified as an old landslide, the survey before the construction of the dam concluded that this slope is stable and will be stable even
