“…. In most cases, dendrochronological data from landslides is used for detailed spatio-temporal analysis of one landslide form (ŁUSZCZYŃSKA & WISTUBA, 2015;NAWROCKA, 2013) or to compare the results of dendrochronological analyses with data on triggering factors, such as heavy rainfall, earthquakes (ŠILHÁN ET AL., 2012). On the other hand, mapping geomorphological processes is becoming increasingly popular.…”

We applied dendrochronological methods for dating landslide activity in the study area (3.75 km 2 ), on the slopes of Sucha Mountain (1040 m a.s.l.), in the Beskid Żywiecki Mountains, in the Western Carpathians. 46 sampling sites were distributed throughout the study area. At each site we sampled 1-3 coniferous trees: Norway spruces (Picea abies Karst.) and/or silver firs (Abies alba Mill.). From each tree 2 cores were sampled: one from the upslope and the other from the downslope side of the stem. Based on tree-ring widths measured for opposite sides of stems we have calculated eccentricity index values and dated past landslide events. Mean frequency of landslides was obtained for each sampling site. Finally, the data was interpolated into a map of landslide activity. Inverse Distance Weighting (IDW) interpolation has been applied. For most of the study area we found medium (19 sites) and low (23 sites) levels of landslide activity. The highest level of activity was recorded for the largest landslide slope and for the one small landslide. The study conducted on Sucha Mountain has shown that dendrochronology can be an effective method for analysing landslide activity and may be useful in further studies, including those for landslide hazard and risk assessments.

“…Dendrogeomorphological anal y sis pre sented in the pa per was car ried out on an ac tive land slide (~2.5 km long) called the Sawicki Land slide, sit u ated in the Beskid Niski Moun tains within the Flysch Carpathians.

As so ci ate Ed i tor: Wojciech Granoszewski We ap plied dendrochronological anal y sis to study an ex ten sive (~2.5 km long) com plex-type land slide in the Beskid Niski Moun tains (Pol ish Flysch Carpathians), which was re ju ve nated in his tor i cal time (the ear li est trans for ma tion oc curred in 1913). We used three com ple men tary meth ods (dat ing of ec cen tric ity of an nual growth rings, ec cen tric ity in di ces, and anal ysis of re ac tion wood), based on seven spe cies of de cid u ous and co nif er ous trees. A to tal of 204 trees were sam pled and 408 cores col lected us ing a Pressler in cre ment borer. Based on the dendrochronological anal y sis, the ac tiv ity of var i ous parts of the land slide in the past cen tury is pre sented, which ap pears to have been di verse and in flu enced mostly by pre cip i ta tion. The up per part of the land slide was ac tive from the 1920s un til the 1940s. In the mid dle sec tion of the land slide, in ten si fi cations of grav i ta tional move ment were re peat edly re corded af ter in tense rain falls through out the en tirety of the last cen tury. The high est land slide ac tiv ity was dendrochronologically de tected in the 1980s and 1990s. In creas ing land slide ac tiv ity during so-called "dry years" may have been re lated to quick dry ing of the bed rock, re sult ing in changes in rock strength pa ram eters. Our re sults in di cate sig nif i cant sus cep ti bil ity of this par tic u lar slope-val ley geosystem in re sponse to even slight hydrogeological changes (in clud ing dry ness), which can trig ger ground move ment.
