Abstract

The AA. test the potential of conifers growing at a low-latitude, high-elevation site as a dendrogeomorphic tool to reconstruct to calendar dates associated rockfall activity. Analysis is based on tree-ring records of Mexican mountain pine growing at timberline (~4000 m a.s.l.) and at the runout fringe of a NNE-facing slope of the dormant Iztaccíhuatl volcano (Mexico), which is subject to frequent rockfalls. The potential and limitations of tree-ring data are demonstrated based on 67 rockfall impacts dated in the increment-ring series of 24 trees since AD 1836. While findings of this paper are site-specific, the study clearly shows the potential of dendrogeomorphic approaches for the understanding of rockfall processes in space and time
