Tectonic and climatic controls on the Chuquibamba landslide (western Andes, southern Peru)
Summary: This study deals with the control of crustal tectonic activity and Altiplano climatic fluctuations in the evolution of the arid western Andes. Based on geomorphic analysis coupled with terrestrial cosmogenic nuclide investigation, we point out the role of active faulting and wet events in the development of the Chuquibamba landslide (southern Peru). Our main outcome is that the last major debris flow coincides in time with the Ouki wet climatic event identified on the Altiplano.

Hitting rock bottom: morphological responses of bedrock-confined streams to a catastrophic flood
Summary: We document the responses of bedrock-confined rivers to an extreme flood which occurred in southeast Queensland, Australia, in 2011. Through a combination of field- and desktop-based analyses we show that widespread removal of coarse-grained mantle occurred, with boulders up to 4m in diameter being locally mobilised. We show that normalised erosion in this extreme event is scaled to basin area and that this large flood has exposed bedrock steps and straths exposing them to ongoing erosion.
