Rapid ASTER imaging facilitates timely assessment of glacier hazards and disasters

Abstract: Glacier‐ and permafrost‐related hazards increasingly threaten human lives, settlements, and infrastructure in high‐mountain regions. Present atmospheric warming particularly affects terrestrial systems where surface and sub‐surface ice are involved. Changes in glacier and permafrost equilibrium are shifting beyond historical knowledge. Human settlement and activities are extending toward danger zones in the cryospheric system. A number of recent glacier hazards and disasters underscore these trends. Difficult … Show more

“…However, in urgent cases such as natural disasters, the repeat period can be reduced to about 2 days, thanks to the ± 8.5°cross-track pointing capabilities of the ASTER sensor, with additional across-track viewing capabilities of up to ± 24°for the VNIR bands only (for a disaster-related example, cf. Kääb et al, 2003).…”

“…At the same time, plans were initiated to build continued cooperation with respect to hazards, climate-change effects and environmental aspects in the high mountains of the Ossetian Caucasus. Since then, several reports on partial aspects of the event have appeared (Desinov and others, 2002;Haeberli and others, 2003;Kääb and others;2003b;Popovnin and others, 2003;Kotlyakov and others, 2004a, b;Petrakov and others, 2004), and an international conference on related aspects was organized in June 2004 at Vladikavkaz ( GRNO-A, 2004). It is now clear the catastrophe constitutes an event of historical dimensions that must be reflected in glacier and permafrost hazard research in high mountain areas.…”

“…The combination of radar and optical satellite data offers particular promise for hazard assessment because it capitalizes on the advantages offered by different parts of the electromagnetic spectrum. Radar imagery can bridge temporal gaps in optical imagery due to darkness or cloud cover (Kääb et al, 2003) and can provide measurements presently not attainable with other imagery, such as millimetre-scale surface displacement. Optical imagery is widely available, free or inexpensive, and can be processed with common software packages.…”

“…Traditional hazard assessments are time-and resource-intensive and are not conducive to regular reassessments. As a result, space-borne remote sensing systems are becoming increasingly important for evaluating hazards (Huggel et al, 2002, Kääb et al, 2003.…”
