Devdoraki Glacier, Kazbek: history of studies of natural hazards in XIX and the beginning of XXI centuries
Published 2016-05-01Get full textThe Devdorak Glacier located on the Eastern slope of Mt. Kazbek is known since the end of the 19th century for its catastrophic ice discharges into the river Terek canyon. The so-called «Kazbek blockages» stopped the river flow, thus leading to formation of a dammed lake. The lake was then broken th...

Specific changes of the Kolka Glacier (the North Caucasus) from 2002 to 2016
Published 2017-12-01Get full textThe process of filling the bed with ice with steep lateral tributaries, which lost support, began almost immediately after the catastrophe on the Kolka Glacier in 2002. Currently, three streams of ice have closed in the rear zone of the circus, forming a single ice massif on the bed. The dimensions...

Glacier reaction to temperature and precipitation change in Central Caucasus, 2001–2010
Published 2015-04-01Get full textThis paper examines changes in surface area and terminus retreat of glaciers in the Greater Caucasus Mountains between 2001 and 2010 using ASTER imagery. The use of consistent high-resolution imagery such as ASTER significantly reduces uncertainties in measurements of glacier shrinkage and retreat a...

Reconstructing mass balance of Garabashi Glacier (1800–2005) using dendrochronological data
Published 2015-04-01Get full textThe exploration whether tree-ring data can be effectually applied for the mass balance reconstruction in Caucasus was the main goal of this research. Tree-ring width and maximum density chronologies of pine (Pinus sylvestris L.) at seven high-elevation sites in Northern Caucasus were explored for th...

Changes of the mass balance of the Garabashy Glacier, Mount Elbrus, at the turn of 20th and 21st centuries
Published 2019-03-01Get full textLong-term series of observations on the glacier of the southern slope of Elbrus manifest the change of two climatic periods in the highlands of the Caucasus. During the first one, relatively cold and snowy period of 1982–1997 with a small positive mass balance, the Garabashi Glacier accumulated a la...
