WHEN TREES MEET ROCKS
Tree rings have numerous applications in geomorphological investigations. We can use dendrochronological methods to assess the movement of glaciers, establish the pace of dune movements, study dynamics of river channels, date earthquakes and many more. But the most common use of tree-ring tools is investigations of mass movement (landslides, debris flows, rock falls, creeping etc). These processes are quite complex and occur as a result of combination of geology, relief, climate and human interventions. Rapid mass movements such as landslides and avalanches can be the cause of widespread death and destruction in the populated areas (in 1970 debris flow in Peruvian Andes travelled with the speed of 90km/h and killed 18,000 people).
Increasing human pressure and climate warming have produced an urgent need for increase of our understanding of these complex land-forming processes. In this sense trees are ideal indicators for investigations of the spatial and temporal dynamics of slope processes over decadal and centennial time scales. Namely, trees provide us with precise dates that can be correlated with precipitation, earthquakes and human interventions.
