On 2 April 2024, a Mw 7.4 earthquake hit Taiwan's eastern coast, causing extensive landslides and damage. We used automated methods combining Earth observation (EO) data with AI to quickly inventory the landslides. This approach identified 7090 landslides over 75 km2 within 3 h of acquiring the EO imagery. The study highlights AI's role in improving landslide detection efforts in disaster response.

This paper presents a new framework for landslide detection using radar and deep learning, informed by data from 73000 landslides across diverse regions in the world. The method showed high accuracy and rapid response potential regardless of weather and illumination conditions. By overcoming the limits of optical satellite imagery, it offers a powerful tool for global landslide detection, benefiting disaster management and advancing methods for monitoring hazardous terrains.

We analysed debris flows in Sichuan, China, using satellite data and simulations to assess check dam efficacy. Our study found that while check dams can mitigate smaller flows, they may increase exposure to extreme events, with up to 40 % of structures in some areas affected. Urban development and reliance on check dams can create a false sense of security, increasing exposure during large debris flows and highlighting the need for risk management and infrastructure planning in hazard-prone areas.

We introduce TerraTrack, an open-source tool for detecting and monitoring slow-moving landslides using Sentinel-2 data. It automates image acquisition, landslide identification, and time-series generation in an accessible and cloud-based workflow. TerraTrack supports early warning, complements InSAR, and offers a scalable solution for landslide hazard identification and monitoring.

In this study, we investigated the geomorphology, sedimentology, and chronology of Tuanjie (seven terraces) and Taiping (three terraces) terraces in Diexi, eastern Tibetan Plateau. Results highlight that two damming and three outburst events occurred in the area during the late Pleistocene, and the outburst floods have been a major factor in the formation of tectonically active mountainous river terraces. Tectonic activity and climatic changes play a minor role.

Landslides occur often across the world, with the potential to cause significant damage. Although a substantial amount of research has been conducted on the mapping of landslides using remote-sensing data, gaps and uncertainties remain when developing models to be operational at the global scale. To address this issue, we present the High-Resolution Global landslide Detector Database (HR-GLDD) for landslide mapping with landslide instances from 10 different physiographical regions globally.

This study created a multi-temporal inventory of glacial lake from 1990 to 2019 throughout the Tibetan Plateau . In here, we demonstrated the quantity and size of glacier lakes have grown by 3285 and 258.82 sq km, respectively. The distribution of glacial lakes across the 17 mountains of TP is uneven, and the pace of area change varies per subregion. Most glacial lakes are distributed in the elevation range of 4400–5400 m above sea level, with an obvious expansion tendency in recent decades.

Short summary
Climate change is causing mountain lakes behind glacier barriers to drain through ice tunnels as catastrophe floods, threatening people and infrastructure downstream. Understanding of how process works can mitigate the impacts by providing advanced warnings. A laboratory study of ice tunnel development improved understanding of how floods evolve. The principles of ice tunnel development were defined numerically and can be used to better model natural floods leading to improved prediction.

Short summary
Due to global warming, the glaciers in the Tibetan Plateau (TP) undergoes rapid melting, leading to an increase in the number of glacial lakes and lake areas. However, these changes are not homogenous throughout TP. Here, we present the 30 years (1990–2019) record of glacial lakes inventory of TP using archived Landsat images. We showed that the number and area of glacial lakes increased by 3285 and 258.82 km2 in the last three decades in TP.

Short summary
In this study, we present the largest publicly available landslide dataset, Globally Distributed Coseismic Landslide Dataset (GDCLD), which includes multi-sensor high-resolution images from various locations around the world. We test GDCLD with seven advanced algorithms and show that it is effective in achieving reliable landslide mapping across different triggers and environments, with great potential in enhancing emergency response and disaster management.
In this study, we present the largest publicly available landslide dataset, Globally Distributed...
