Tree-Ring Analysis and Rockfall Research: Possibilities and Limitations

摘要: Over the last few years, rockfall research has increasingly focused on hazard assessment and risk analysis. Input data past activity were gathered from historical archives lichenometric studies or obtained through frequency-volume statistics. However, records are generally scarce, lichenometry may only yield with relatively low resolutions. On forested slopes, in contrast, tree-ring analyses help, providing annual over long periods. The purpose of present literature review is to survey current state investigations dealing sequences activity, emphasis extent which dendrogeomorphology contribute research. A brief introduction describes how dendrogeomorphological methods can natural Secondly, an account provided output investigating frequencies, volumes, spatial distributions triggers activity. potential strengths then presented. In a final step, we mention weaknesses tree rings as discussed promising directions for further outlined.
