“…Methods such as cosmo-nucleide dating have allowed dating fault surfaces including those with lateral offsets (e.g., Sanchez et al, 2010a). The application of smallperiod (<1 Ma) dating methods allows comparisons between climatic -erosional cycles and tectonic motions.…”

“…Similarly, transpressional domains (e.g., Mont Blanc; Rolland et al, 2008) also connect with strike-slip faults. Continuous ductile to brittle deformation, seismicity and morphological offsets evidence the permanence of such motions, occurring during the Quaternary ( [Sanchez et al, 2010a] and [Sanchez et al, 2010b] ). The overall dextral motion that is observed across the Alpine arc contradicts any model of westward indentation of the European margin by the Apulian microplate.…”

Deciphering orogenic evolution requires the integration of a growing number of geological and geophysical techniques on various spatial and temporal scales. Contrasting visions of mountain building and lithospheric deformation have been proposed in recent years. These models depend on the respective roles assigned to the mantle, the crust or the sediments. This article summarizes the contents of the Special Issue dedicated to "Geodynamics and Orogenesis" following the "Réunion des Sciences de la Terre" 2010 conference held in Bordeaux, France. Further, based on the example of the Western Alps-Mediterranean domain we emphasize the possibility to integrate long and short term, plate-to sample-scale, datasets in order to constrain orogenic evolution.

“…The reach between Mirabeau and Sisteron has the complete range of terraces revealing increased elevations upstream. This reach attracted earlier terrace studies [43,49,50] and it has been affected by recent tectonics [16,17,24,38,[51][52][53][67][68][69][70][71][72].…”

“…More recent work concerned with rates of incision and loss of surface material from terraces has used 10 Be cosmic ray exposure dating [10,11,13]. This technique has also been used to date the late glacialinterglacial transition (12 and 15 ky) [38]. Post-glacial tectonic activity was also obtained from fault scarps (11 and 7-8 ky), associated with landslides [39].…”

A morphological study of Durance River terraces from Tallard to Avignon, South-East France

AbstractThis study of Durance River terrace morphologies in the lower 200 km of the valley shows that terrace ages, elevations and heights above the river generally all increase upstream. It is based on extensive fieldwork checked against geological maps and memoirs. Subdivision of the valley, based on gorges and former tectonic blockages, is relevant because there are no Durance terraces downstream of Mallemort and there are considerable differences between each reach. For most of the Pleistocene, the river was diverted through the Crau Plains to the sea. Below the Mirabeau gorge, there are a few narrow low and middle terraces. The best terrace development is between Mirabeau and the Sisteron defile. Upstream of that barrier there is glacial dominance. Changes in terrace continuity are illustrated by means of height-range diagrams and their rates of dissection have been quantified approximately, based on cosmic ray exposure age modelling. Climate forcing cannot explain all the changes found. The influence of tectonic activity was found to increase in an upstream direction and also with age on the southwestern flanks of the Alps.

“…For instance, the West Usambara Mountains located within the Eastern Arc receive rainfall reaching a maximum of 2000 mm on windward portions of the mountain, which drops to 600 mm on leeward [38]. Terrain uplift and shaking associated with plate tectonics and powerful streams cutting in the hillsides can trigger landslides [39]. Rock fall and rock topple hazards are most common in areas of exposed limestone overlying eroding shales.…”

This paper intended to inventorize the occurrence of landslides in Tanzania in temporal and spatial terms. Specifically, the inventory focused on identifying areas in Tanzania which are prone to landslides, identifying the frequency of landslide occurrence in the country, identifying the underlying and triggering factors for landslides, the socio-economic impacts of landslides and assessing the people's perception of landslides in Tanzania. Identification and mapping of landslide was achieved through the use primary and secondary sources of information. Primary data was acquired through exploratory field visit to the 5 landslide scars in the north and south Pare Mountains in the northern highlands of Tanzania. Short discussion with local people in the areas was made to gain insights into their perception of landslides. Secondary data was acquired through the review of achieved sources. This review was made in respect of the landslides that were not covered by the aforementioned exploratory field visit. The EM-DAT was also used to provide information on the number of landslide events, fatalities and socio-economic impacts. Google Earth™ search and image interpretation were used to located and describe landslides in other regions of the country that were not covered by the aforementioned exploratory field study. A 90 m resolution Digital Elevation Model (DEM) from USGS for Tanzania was used to map the landslide scars identified through Google Earth search. Google Earth search and image interpretation were supported by secondary information from archived sources. The inventory noted that landslides in Tanzania have received relatively limited attention both in the literature and in government disaster management plans. With exception of studies conducted in Uluguru Mountain in 1970s, no formal landslide research has been made in recent years. Despite extensive web searches, no landslide inventory has been made in Tanzania. This may presumably be due to existing assumption that landslides in Tanzania have low frequency of occurrence and are localized compared to other disasters such as floods, epidemics and drought, whose occurrence affect many more people, drawing more community, government and media attention. This has thus, affected the way landslide events are reported and managed in the country. This assertion however, does not preclude the fact that one/few landslide events, depending on their magnitude, where they occur and nature of elements at risk, can affect significant number of people and vice versa. This inventory has also documented cultural perspectives on landslides. Care must be taken to incorporate appropriate indigenous knowledge and people's perception pertaining to landslides and other disasters as these are critical in designing and implementing culturallyinformed and low cost disaster management strategies. This may, in turn, obviate the need or reduce cost for early warning systems. Landslide information provided by some reviewed sources is limited in time and space. Most of the visi...
