Title: Sediment: The new silent disaster

Abstract

The sedimentary archive is our only record of how landscapes, and their hazards, have responded to past climate and tectonic change. These records are the only data we have to test global system models. However, we still don’t understand exactly what these sedimentary records preserve. This talk will interrogate how climate and tectonic signals influence the erosion in mountain regions and how this is translated downstream into sedimentary records. It will focus on the pristine Chilean and Argentinian Andes and consider the evolution of mountain landscapes over >100yr timescales. It will then explore how human activity might be impacting erosion signals in these regions and present new research for understanding the combined impact of climate and human decision making on the evolution of mountain hazards.
