Surge of the Bivachny Glacier in 2012–2015

Abstract

The surge of the Bivachny Glacier that occurred in 2012–2015 is analyzed with the use of photographing performed from International Space Station in 2001–2015 together with data of the satellite monitoring of 1972–2000. This surge happened in 31 years after the similar previous event of 1972–1976. Dynamics of numerous glacier branches causing activation of the lower glacier part that is so called “dead” zone (more than 7 km in length) is shown. Just before its stop the front part of the surging glacier had reached the main trunk of the Fedchenko Glacier.
