Anatomical growth response of Fagus sylvatica L. to landslide movements.

Determining the age of landslide events is crucial for determining landslide risk, triggers, and also for predicting future landslide occurrence. Currently, the most accurate method for dating historical landslide events is dendrogeomorphic analysis. Unfortunately, the standard use of macroscopic growth responses of damaged trees for dating landslide activity suffers from many shortcomings.

Distinct types of landslides in moraines associated with the post-LIA glacier thinning: Observations from the Kinzl Glacier, Huascarán, Peru.

The Kinzl Glacier is a unique dendritic-type glacier of the Peruvian Cordillera Blanca and is surrounded by well-developed Little Ice Age (LIA) moraines. Based on field observations and analysis of historical photographs (since 1932) and remotely sensed images (since 1948), we interpret distinct mechanisms of landslides in these moraines and link them to glacier retreat and thinning. Three types of landslides are distinguished according to the cross-profile morphology: (i) type "N", (ii) type "M" and (iii) type "A".
