“…2). Mountain ridges, formed mainly by palaeozoic crystalline rocks, are separated by wide lenticular or narrow, linear intermountain depressions, containing Neogene and Quaternary deposits, mainly sandstone, siltstone with gypsum interbeds, and conglomerates (Strom and Abdrakhmatov, 2017). Mesozoic and Paleogene deposits are typical of the foothill areas.…”

“…According to the international Cruden and Varnes 1996 classification, landslides phenomena in Central Asia include rockslides/rock avalanches, rotational/translational slides and mud/debris flows (often involving loess), which are triggered by natural events such as earthquakes, floods, rainfall and snowmelt (Behling et al, 2014;Golovko, 2015;Havenith et al, 2006aHavenith et al, ,b, 2015aKalmetieva et al, 2009;Saponaro et al, 2014;2015;Strom and Abdrakhmatov, 2017;2018). Glacial lakes outburst flood phenomena, caused by the breech of natural glacial dams, often result in large scale catastrophic mud/debris flows.…”

Abstract. Central Asia is an area characterized by complex tectonics and active deformation; the related seismic activity controls the earthquake hazard level that, due to the occurrence of secondary and tertiary effects, has also direct implications on the hazard related to mass movements as landslides, which are responsible for an extensive number of casualties every year. Climatically, this region is characterized by strong rainfall gradient contrasts, due to the diversity of climate and vegetation zones. The region is drained by large, partly snow- and glacier-fed rivers, that cross or terminate in arid forelands; therefore, it is affected also by a significant river flood hazard, mainly in spring and summer seasons. The challenge posed by the combination of different hazards can only be tackled considering a multi-hazard approach harmonized among the different countries, in agreement with the requirements of the Sendai Framework for Disaster Risk Reduction. This work was carried out within the framework of the SFRARR Project (“Strengthening Financial Resilience and Accelerating Risk Reduction in Central Asia”) as a part of a multi-hazard approach, and is focused on the first landslide susceptibility analysis at a regional scale for Central Asia. To this aim the most detailed landslide inventories, covering both national and transboundary territories were implemented in a Random Forest model, together with several independent variables. The proposed approach represents an innovation in terms of resolution (from 30 to 70 m) and extension of the analysed area with respect to previous regional landslide susceptibility and hazard zonation models applied in Central Asia. The final aim was to provide a useful tool for land use-planning and risk reduction strategies to landslide scientists, practitioners and administrators.

“…The study zone lies in central Tajikistan and occupies an area of about 1270 km 2 (Figure 1a), known as the Hissar-Allay mountains region, bounded by the latitudes 38°55' and 39°58' N and longitudes 68°15' and 74°10' E. The Hissar-Allay region is a sublatitudinal-spreading ridge, consist of Hissar, Zeravshan, and Turkistan mountain systems (Figure 1b) divided by broad valleys of tectonic origins. Some peaks rise to 4000 m, but average topographical elevation ranges between 700 and 3000 m.a.s.l.…”

An increasing amount of landslides leading to significant human and economic consequences is a primary concern for the government of Tajikistan and local authorities. Based on the Committee on Emergency Situations data, from 1996 to 2018, there were 3460 emergencies and more than 1000 fatalities because of earthquake-triggered and rainfall-induced landslides in the region. In addition, landslides caused severe damage to houses and infrastructure facilities due to the population’s lack of landslide hazard knowledge. Therefore, current research focuses on developing a regional-scale landslide inventory map in the Hissar–Allay region, central Tajikistan, where the population density is much higher than at other mountainous territories. In recent decades, the enhancements in geographic information systems, the open access to high-resolution remote sensing data, and an extensive field survey allowed us to identify 922 landslides possible along the highway corridor in the Hissar–Allay region. Based on Varnes’s system, these landslides are classified into four categories: debris flows, rockfalls, shallow landslides, and complex (deep-seated) landslides, considering landslides morphology, geology, deformation of slopes, degree and aspect of slopes, and weathered and disintegrated zones on slopes in the study area. The results show that 8.24% of the total study area is affected by landslides. Along the highway corridor in the Hissar–Allay region there are 96 bodies of deep-seated landslides and 216 rockfall catchments, 273 debris flow catchments, and 313 shallow landslides. Thus, shallow landslides are the most frequent type of movement. In addition, landslide frequency-area distribution analysis shows that shallow landslides are frequent with an area of 1.88E+04 m2; most frequent debris flow channels have a place of 5.58E+05 m2; rockfalls, for its part, are rife with an area of 1.50E+05 m2, and frequent complex landslides have an area of 4.70E+06 m2. Furthermore, it was found out that slopes consist of Silurian formation comprise shales, pebbles, sands, loams, and limestones, metamorphic clays are exposed to landslides more than other geological formations because of the layered structure and their broad spatial distribution in the study area. As the first applied research to compile a landslide inventory map in the Hissar–Allay region on the regional scale, our study provides a sound basis for future explorations of landslide susceptibility, hazard, and risk assessment for this region.

“…Central Asia is also prone to earthquakes as demonstrated by several regional-scale studies carried out in the last decades (Ulomov et al, 1999;Bindi et al, 2012;Ullah et al, 2015). Landslides, together with earthquakes and floods, are very frequent in Central Asia and, in the past, were often triggered by natural events such as earthquakes, floods, rainfall and snowmelt (Saponaro et al, 2014;Strom and Abdrakhmatov, 2017). The type and spatial distribution of floods and landslides is also expected to vary due to climate change, which is strongly affecting the region.…”

Abstract. The Central Asia region encompasses a wide variety of climatic areas and geological settings. It is therefore prone to multiple hazards which can affect different parts of the region, including transboundary areas. Floods and landslides are increasing in number and intensity due to climate change, while earthquakes are a well-known threat for the region. Knowing the location, type and characteristics of exposed assets is paramount in order to develop disaster risk reduction strategies. Floods, landslides and earthquakes can affect a wide range of exposed assets in the region, but past research efforts were mostly focused on residential buildings. Here, we develop the first regionally-consistent exposure database for selected asset types (namely, non-residential buildings, transportation and croplands) in Central Asia. We assembled the available global and regional datasets together with country-based information provided by local authorities and research groups, including reconstruction costs. The exposure database provided here supports further analysis to integrate data from national and sub-national projects and support regional-scale disaster risk reduction strategies.
