One of the most far-reaching glacier-related hazards in the Tian Shan Mountains of Kyrgyzstan is glacial lake outburst floods (GLOFs) and related debris flows. An improved understanding of the formation and evolution of glacial lakes and debris flow susceptibility is therefore essential to assess and mitigate potential hazards and risks. Non-statio...
New data on continuing advance of the Kamchatka glaciers Erman, Vlodavets, Sopochny, Schmidt, and Bogdanovich were obtained as a result of analysis of aerospace information taken at different times. Glacier Erman advances during the past 70 years (1945–2016). Over the period from 1949 to 2016, its area increased by 4.7 km2 and the length – by 3.3 k...
This research is devoted to Tangjiashan Lake, a quake landslide-dammed lake, situated in Sichuan Province, China, which was formed by a landslide triggered by the Wenchuan Earthquake on 12 May 2008. A STREAM_2D two-dimensional hydrodynamic model of Russia was applied to simulate the process of two flood scenarios: 1, lake dam outbreak, and 2, dam o...
Climate change has been shown to increase the number of mountain lakes across various mountain ranges in the World. In Central Asia, and in particular on the territory of Uzbekistan, a detailed assessment of glacier lakes and their evolution over time is, however lacking. For this reason we created the first detailed inventory of mountain lakes of...
Lahars are highly concentrated, water-saturated volcanic hyperconcentrated flows or debris flows containing pyroclastic material and are a characteristic mass movement process on volcanic slopes. On Kamchatka Peninsula (Russian Federation), lahars are widespread and may affect remote settlements. Historical records of past lahar occurrences are gen...
At 16:30 (Beijing time) on August 3rd, 2014, an Ms 6.5 earthquake occurred in Ludian County in Yunnan Province, China. The Ludian earthquake triggered a collapse in Chapingzi, right bank of the Niulanjiang River, and a landslide in Hongshiyan at the left bank on the same location. These events occurred 1.5 km
downstream of the Hongshiyan hydropower...
Glacier lakes pose threat to downstream settlements and infrastructure. In
recent decades the number and area of lakes have been growing at an accelerating rate due to worldwide glacier shrinkage. In the Russian Caucasus this process is understudied. We
present results obtained during a 12-year (1999–2010) continuous field monitoring of the Bashkar...
The importance of mountain lakes studies is related to the increasing
threat of natural disasters, associated with lake outbursts and debris
flows formation, because of population growth on exposed areas. The
outburst hazard has not been sufficiently researched, there is a lack of
data because of the lakes inaccessibility and remote sensing data is...
We have analyzed changes in the area of Genaldon glacial disaster on 20 September 2002 in the Republic of North Ossetia-Alania (Russia). Using results of annual fieldwork (2002-2010), topographic surveys in 2002, 2003, 2004 and 2009, and interpretation of satellite imagery, we have determined the rate of glacier regeneration in the Kol ka cirque an...
Debris flow is a kind of geological hazard occurring in mountain areas. Its velocity is very important for debris flow dynamics research and designing debris flow control works. However, most of past researches focused on surface velocity and mean velocity of debris flow, while few researches involve its internal velocity because there is no availa...

Measuring the internal velocity of debris flows is very important for debris flow dynamics research and designing debris flow
control works. However, there is no appropriate method for measuring the internal velocity because of the destructive power
of debris flow process. In this paper, we address this problem by using the relationship between vel...
The Wenchuan (汶川) earthquake on 12 May 2008 induced a large number of landslides, collapses, and rockfalls along the Longmenshan
(龙门山) fault. The landslide in Niujuan (牛圈) Valley (named Niujuan landslide), close to the epicenter, is one that travelled
a long distance with damaging consequences. Using QuickBird satellite images and GIS tools, the se...
Numerous glacier lakes have formed in recent decades due to worldwide glacier retreat induced by climate change. These lakes, dammed by glaciers and moraine ridges, are hazardous because of potential glacial lake outburst flows (GLOF). The GLOF probability is increasing in the Russian Central Caucasus, like at the Bashkara glacier which has been ex...
We studied features of the formation of volcanic debris flows (lahars) on the basis of our field research in 2008, interpretation of satellite images, and analysis of literature on volcanic eruptions of Klyuchevskoy and Shiveluch volcanoes in Kamchatka Peninsula, Russia.
