“…Indeed, most Kingata surges last 3-4 years, similar to those in the Karakoram. The extreme short-lived surges, and the large-scale velocity variations of W9 and E10 (1-2 years), are similar to surge events reported on Shakesiga Glacier in the Karakoram (Quincey et al, 2015) and Kelayayilake Glacier on Mont Tobe Feng (Lv et al, 2016).…”

“…The surges of E1 and E7 showed minor surface feature advances and the other five surges (E9, E11, E12, E13, and W6) caused the rearrangement of surface features in the middle parts of the glacier tongue, as well as overriding the remnant left by a possible previous glacier surge, similar to the surges of Braldu and Unnamed1 Glaciers in the Karakoram (Quincey et al, 2015). This type of glacier surge is common in eastern Pamir (Lv et al, 2016;Shangguan et al, 2016) although their evolutions differ both spatially and temporally. We suggest these flow instabilities can be contributed to the geomorphological characteristics of different glaciers, such as the slope of the entire glacier, the size of accumulation area, the width of the outlet, and so on.…”

“…Glacier (Lv et al, 2016;Shangguan et al, 2016) and Muztag Glacier (Yang et al, 2013). No in-situ climate data exist for this region making it difficult to disentangle glacier response to a change in accumulation from other factors.…”

Abstract. Glaciers in the Pamir Mountains are generally acknowledged to be in a stable state and show the least glacial retreat in High Mountain Asia; however, they are also some of the most dynamic glaciers in the region and their behaviour has been spatially variable in recent decades. Few data exist for these glaciers, in particular relating to how they are responding to recent climatic changes. Here, we utilize Landsat 7, Landsat 8, and ASTER optical images acquired between 1999 and 2016 to characterise the dynamics of the glaciers in the Kingata Mountains, located in the eastern Pamir. We quantify the velocity, areal, and frontal changes of these glaciers, which provide us with valuable data on their recent dynamic evolution and an indication of how they may evolve in future years. We highlight 28 glaciers among which 17 have changed markedly over the study period. We identify 4 advancing glaciers, 1 receding glacier, and 12 surge-type glaciers. The dynamic evolution of the glacier surges shows some similarity with those of the nearby Karakoram, suggesting that both hydrological and thermal controls are important for surge initiation and recession. Topography seems to be a dominant control on non-surge glacier behaviour in the KM, with the north-side of the divide characterised by steep, avalanche-fed basins and glacier tongues now approaching recession in contrast to those on the south-side of the divide that capture the majority of precipitation and have much broader plateau-like accumulation zones. This study is the first synthesis of glacial motion across this region and provides a baseline with which to compare future changes.

“…Many researches about surge-type glaciers have hypothesized that climate may be incentives for glacier surging, considering that dramatic changes in climate may lead to catastrophic events [51]. The nearest weather station to this study area is the Tuotuohe Station (Figure 1a).…”

“…The active phase of the hydrologically controlled surge is shorter, and the active phase thermally controlled surges is longer [56]. Lv et al studied the Kelayayilake Glacier, which surged dramatically during the Spring of 2015 (From April to July), and came to the conclusion that hydrological factors controlled this surging event [51]. Lv et al studied the 28 glaciers in Karakoram and found 13 surge-type glaciers.…”

A surge-type glacier is a special and dangerous type of glacier, which can advance quickly in a short-time with cycles. Glaciers in the Yangtze River headwater are generally acknowledged to be in a stable state. However, not all of those glaciers are stable. In this paper, five glaciers from the Yangtze River headwater glacier were selected as the experimental subjects, and multi-source remote sensing images were used to study and analyze the surge behavior over the past 30 years. Based on the Landsat series data, ERS-2, and ENVISAT radar data, this paper extracts the glacier centerline information, glacial area information, and glacial flow velocity during different time periods from 1988 to 2018, which are used to monitor the active periods of glacier surges. We found three surge-type glaciers in the study area. The glacial characteristics of the three glaciers showed some drastic changes, they can advance quickly nearly 800 m in active periods, their area change can reach 2.0 × 106 m2, and their flow velocity can suddenly increase by dozens of times. Surging periods and the initiated time of the three glaciers are different, which are locked in 1997, 2003, and 1997–1998. All those surges ended within one to two years. We suggest that the surges in this paper are dominated by hydrological conditions.
