Hydro-morphological processes (HMP, any natural phenomenon contained within the spectrum defined between debris flows and flash floods) are globally occurring hazards which pose great threats to our society, leading fatalities economical losses. For this reason, understanding dynamics behind HMPs is needed aid in hazard risk assessment. In work, we take advantage of an explainable deep learning model extract global local interpretations HMP occurrences across whole Chinese territory. We use a neural network architecture interpret results through spatial pattern SHAP values. doing so, can understand prediction on hierarchical basis, looking at how predictor set controls overall susceptibility as well same level single mapping unit. Our accurately predicts with AUC values measured ten-fold cross-validation ranging 0.83 0.86. This predictive performance attests for excellent skill. The main difference respect traditional statistical tools that latter usually lead clear interpretation expense high performance, otherwise reached via machine/deep solutions, though interpretation. recent development AI key combine both strengths. explore combination context modeling. Specifically, demonstrate extent one enter new data-driven interpretation, supporting decision-making process disaster mitigation prevention actions.

Abstract This article investigates the multifaceted dimensions to understand interrelatedness among global change drivers and their implications for landslide hazards disaster risk. Drawing on empirical research, it utilised a mixed-methods design; research combined diverse data sources experiential insights interdependencies bounded by local context scale. The findings underscore urgent need holistic approaches that consider complex of landslides as socio-natural change, emphasising importance collaboration, innovation, international cooperation in building resilience mitigating adverse effects risk systems societies. Furthermore, challenge reducing lies understanding addressing interplay between socio-environmental transformations geodynamic processes. escalating climate urban expansion, deforestation are anticipated magnify occurrence landslides, thereby posing significant risks human lives, infrastructure, ecosystems, livelihoods. However, most importantly, these further compounded environmental, social, economic, political, cultural, technological spheres associated with globalisation. systemic nature risk, particularly changing world, highlights interconnectedness different systems, resulting causality cascading impacts. These contribute broader discourse sustainability providing evidence supports integrated achieving long-term reduction based upon equitable sustainable use territories while integrating robust management strategies ensure resilient communities ecosystems.

Abstract. The increasing availability of long-term observational data can lead to the development innovative modelling approaches determine landslide triggering conditions at a regional scale, opening new avenues for prediction and early warning. This research blends strengths existing with capabilities generalized additive mixed models (GAMMs) develop an interpretable approach that identifies seasonally dynamic precipitation shallow landslides. model builds upon 21-year record landslides in South Tyrol (Italy) separates induced from did not. accounts effects acting four temporal scales: short-term “triggering” precipitation, medium-term “preparatory” seasonal effects, across-year variability. It provides relative probability scores were used establish thresholds optimal performance terms hit false-alarm rates, as well additional related user-defined scores. GAMM shows high predictive indicates more is required induce summer than winter/spring, which presumably be attributed mainly vegetation temperature effects. discussion illustrates why quality input data, study design, transparency are crucial using advanced data-driven techniques.

Understanding how rainfall events influence the pattern and magnitude of landslide response is an important research focus from geomorphological hazard planning perspectives. Few studies quantitatively relate spatial patterns in landslides, largely due to difficulties acquiring inventories data on for individual storm events.

Shallow landslide initiation typically results from an interplay of dynamic triggering and preparatory conditions along with static predisposition factors. While data-driven methods for assessing susceptibility or establishing rainfall-triggering thresholds are prevalent, integrating spatio-temporal information large-area prediction remains a challenge. The main aim this research is to generate spatial model that operates at daily scale explicitly counteracts potential errors in the available data. Unlike previous studies focusing on space–time modelling, it places strong emphasis reducing propagation data into modelling results, while ensuring interpretable outcomes. It introduces also other noteworthy innovations, such as visualizing final predictions linked true positive rates false alarm by using animations highlighting its application hindcasting scenario-building. initial step involves creation spatio-temporally representative sample presence absence observations study area South Tyrol, Italy (7400 km2) within well-investigated terrain.
