Here, we applied an image tracking approach on high-resolution aerial imagery to infer surface kinematics of 129 mapped rock glaciers in the Kaunertal, Austrian Alps. We find significant surface movement for 30 features with mean velocities falling between 0.11 and 0.29 m yr−1 and a maximum of 1.7 m yr−1. Local analysis and comparison to earlier studies reveals significant increases in rock glacier velocities in the study area. From the rock glacier inventory and high-resolution digital topography, we computed a series of morphometric parameters to analyze potential controls on rock glacier creep and to predict rock glacier activity using random forests and logistic regression models. The results point towards a stronger dependence of velocities on parameters describing general inclination, potentially acting as proxies for internal rock glacier properties, while activity states seem to be regulated mainly by rock glacier dimensions and topoclimate. Using a parameter subset, we successfully separated active from inactive rock glaciers with accuracies of up to 77.5%, indicating a promising approach to predict rock glacier activity solely relying on parameters that can be derived from regionally available data sets lok: 47886793 3 exp: 47886793 3 1 #EPN 201B/01 $007-05-21 $t23:23:38.153 201C/01 $007-05-21 201U/01 $0utf8 203@/01 $01151593877 208@/01 $a07-05-21 $bl 209S/01 $S0 $uhttps://freidok.uni-freiburg.de/data/172009 $XH lok: 47886793 5 exp: 47886793 5 1 #EPN 201B/01 $007-05-21 $t23:23:38.160 201C/01 $007-05-21 201U/01 $0utf8 203@/01 $01151593885 208@/01 $a07-05-21 $bl 209S/01 $S0 $uhttps://freidok.uni-freiburg.de/data/172009 $XH lok: 47886793 8 exp: 47886793 8 1 #EPN 201B/01 $007-05-21 $t23:23:38.165 201C/01 $007-05-21 201U/01 $0utf8 203@/01 $01151593893 208@/01 $a07-05-21 $bl 209S/01 $S0 $uhttps://freidok.uni-freiburg.de/data/172009 $XH lok: 47886793 10 exp: 47886793 10 1 #EPN 201B/01 $007-05-21 $t23:23:38.171 201C/01 $007-05-21 201U/01 $0utf8 203@/01 $01151593907 208@/01 $a07-05-21 $bl 209S/01 $S0 $uhttps://freidok.uni-freiburg.de/data/172009 $XH lok: 47886793 11 exp: 47886793 11 1 #EPN 201B/01 $007-05-21 $t23:23:38.189 201C/01 $007-05-21 201U/01 $0utf8 203@/01 $01151593915 208@/01 $a07-05-21 $bl 209S/01 $S0 $uhttps://freidok.uni-freiburg.de/data/172009 $XH lok: 47886793 21 exp: 47886793 21 1 #EPN 201B/01 $007-05-21 $t23:23:38.199 201C/01 $007-05-21 201U/01 $0utf8 203@/01 $01151593931 208@/01 $a07-05-21 $bl 209S/01 $S0 $uhttps://freidok.uni-freiburg.de/data/172009 $XH lok: 47886793 23 exp: 47886793 23 1 #EPN 201B/01 $007-05-21 $t23:23:38.205 201C/01 $007-05-21 201U/01 $0utf8 203@/01 $0115159394X 208@/01 $a07-05-21 $bl 209S/01 $S0 $uhttps://freidok.uni-freiburg.de/data/172009 $XH lok: 47886793 24 exp: 47886793 24 1 #EPN 201B/01 $007-05-21 $t23:23:38.210 201C/01 $007-05-21 201U/01 $0utf8 203@/01 $01151593958 208@/01 $a07-05-21 $bl 209S/01 $S0 $uhttps://freidok.uni-freiburg.de/data/172009 $XH lok: 47886793 25 exp: 47886793 25 1 #EPN 201B/01 $007-05-21 $t23:23:38.215 201C/01 $007-05-21 201U/01 $0utf8 203@/01 $01151593966 208@/01 $a07-05-21 $bl 209S/01 $S0 $uhttps://freidok.uni-freiburg.de/data/172009 $XH lok: 47886793 36 exp: 47886793 36 1 #EPN 201B/01 $026-05-25 $t02:41:53.115 201C/01 $026-05-25 201U/01 $0utf8 203@/01 $01304889920 208@/01 $a26-05-25 $bl 209S/01 $S0 $uhttps://freidok.uni-freiburg.de/data/172009 $XH lok: 47886793 49 exp: 47886793 49 1 #EPN 201B/01 $007-05-21 $t23:23:38.220 201C/01 $007-05-21 201U/01 $0utf8 203@/01 $01151593974 208@/01 $a07-05-21 $bl 209S/01 $S0 $uhttps://freidok.uni-freiburg.de/data/172009 $XH lok: 47886793 72 exp: 47886793 72 1 #EPN 201B/01 $007-05-21 $t23:23:38.236 201C/01 $007-05-21 201U/01 $0utf8 203@/01 $01151594008 208@/01 $a07-05-21 $bl 209S/01 $S0 $uhttps://freidok.uni-freiburg.de/data/172009 $XH lok: 47886793 107 exp: 47886793 107 1 #EPN 201B/01 $007-05-21 $t23:23:38.241 201C/01 $007-05-21 201U/01 $0utf8 203@/01 $01151594016 208@/01 $a07-05-21 $bl 209S/01 $S0 $uhttps://freidok.uni-freiburg.de/data/172009 $XH lok: 47886793 108 exp: 47886793 108 1 #EPN 201B/01 $007-05-21 $t23:23:38.245 201C/01 $007-05-21 201U/01 $0utf8 203@/01 $01151594024 208@/01 $a07-05-21 $bl 209S/01 $S0 $uhttps://freidok.uni-freiburg.de/data/172009 $XH lok: 47886793 204 exp: 47886793 204 1 #EPN 201B/01 $007-05-21 $t23:23:38.251 201C/01 $007-05-21 201U/01 $0utf8 203@/01 $01151594032 208@/01 $a07-05-21 $bl 209S/01 $S0 $uhttps://freidok.uni-freiburg.de/data/172009 $XH lok: 47886793 205 exp: 47886793 205 1 #EPN 201B/01 $007-05-21 $t23:23:38.256 201C/01 $007-05-21 201U/01 $0utf8 203@/01 $01151594040 208@/01 $a07-05-21 $bl 209S/01 $S0 $uhttps://freidok.uni-freiburg.de/data/172009 $XH
