We investigated methods to improve the prediction of landslides triggered by heavy rainfall in southern Chile, utilising local soil and climate data. We tested different models and selected the most critical environmental factors. We improved the process for making forecasts in areas with limited monitoring. Our results help create faster and more reliable warnings and can guide safety planning in other mountain regions facing similar risks.

We investigated how volcanic soils and heavy rainfall trigger dangerous debris flows in the southern Andes. Our findings show saturated volcanic-soils above less permeable glacial deposits create ideal conditions for slope failures. Monitoring soil moisture and surface changes helps predict these events. This knowledge aids in protecting communities from debris flow hazards, increasingly important under climate change.

We develop for the first time a rainfall-induced landslide early warning system for the south of Chile. We used forecast precipitation values at different scales using mesoscale models to evaluate the probability of landslides using statistical models. We showed the feasibility of implementing these models in future, supporting stakeholders and decision-makers.

Peatlands in Chilean Patagonia store large amounts of carbon and help mitigate climate change. We measured carbon dioxide exchange over a year in a North Patagonian peatland, showing that commercial Sphagnum moss harvesting reduces its carbon sink function. Sites with higher harvesting intensity released carbon dioxide, while undisturbed sites sequestered it. We conclude that sustainable practices are essential to protect the climate role of Patagonian peatlands.

Short summary
Through a physical model, we explored how lacier geometry and topography configuration constrains glacier thinning in the Patagonian Icefields, the world's main glacial freshwater reservoir after Antarctica and Greenland. Our results indicate that about 53 % of the Patagonian Icefield ice flow is susceptible to thinning. Our findings allow for identifying priority glaciers for future research considering climate change projections.

In spite of enhanced technologies, many large cryospheric events remain unreported because of their remoteness, inaccessibility, or poor communications. In this Brief communication, we report on a large ice-debris avalanche that occurred sometime between 16 and 21 August 2022 in the Kanchenjunga Conservation Area (KCA), eastern Nepal.

Short summary
Links between debris flow and volcanic evolution are an open question in the southern Andes. We modelled the catastrophic debris flow using field data, a geotechnical approach and numerical modelling of the Petrohué event (Chile, 2017). Our results indicated new debris-flow-prone zones. Finally, we propose considering connections between volcanoes and debris flow in the southern Andes.
