Incorporating InSAR kinematics into rock glacier inventories: insights from 11 regions worldwide

| description | <p>Rock glaciers are landforms related to permafrost creep that are sensitive
to climate variability and change. Their spatial distribution and kinematic
behaviour can be critical for managing water resources and geohazards in
periglacial areas. Rock glaciers have been inventoried for decades
worldwide, often without assessment of their kinematics. The availability of
remote sensing data however makes the inclusion of kinematic information
potentially feasible, but requires a common methodology in order to create
homogeneous inventories. In this context, the International Permafrost
Association (IPA) Action Group on rock glacier inventories and kinematics
(2018–2023), with the support of the European Space Agency (ESA) Permafrost
Climate Change Initiative (CCI) project, is defining standard guidelines for
the inclusion of kinematic information within inventories. Here, we
demonstrate the feasibility of applying common rules proposed by the Action
Group in 11 regions worldwide. Spaceborne interferometric synthetic
aperture radar (InSAR) was used to characterise identifiable moving areas
related to rock glaciers, applying a manual and a semi-automated approach.
Subsequently, these areas were used to assign kinematic information to rock
glaciers in existing or newly compiled inventories. More than 5000 moving
areas and more than 3600 rock glaciers were classified according to their
kinematics. The method and the preliminary results were analysed. We
identified drawbacks related to the intrinsic limitations of InSAR and to
various applied strategies regarding the integration of non-moving rock
glaciers in some investigated regions. This is the first internationally
coordinated work that incorporates kinematic attributes within rock glacier
inventories at a global scale. The results show the value of designing
standardised inventorying procedures for periglacial geomorphology.</p> |
