High-resolution geomorphic data enable the precise acquisition of these displaced landforms, facilitating detailed analysis of slip distributions along faults and offering quantitative constraints on the growth and rupture history of faults.

By interpreting and distinguishing different geomorphic markers, we identified and measured 436 right-lateral offsets along the Luoshan Fault. Based on statistical analysis methods, we determined that there were six strong earthquakes within 10 m of the cumulative displacement along the Luoshan Fault. Except for the latest event, the other five strong events showed regular displacement increments of approximately 1.9 m, revealing a strong earthquake pattern of approximate characteristic slip. The different cumulative displacement distributions correspond to various stages of fault growth. The growth pattern of the Luoshan Fault evolves from fault tip propagation and linkage (Events 1–5) to a mode of growth with a constant fault length but increased cumulative displacement (Event 6). Based on the displacement distribution along the Luoshan Fault, the northern segment is more likely to experience earthquake events, with magnitudes ranging from Mw 6.84 to 7.12.</div></div>","PeriodicalId":34142,"journal":{"name":"Quaternary Science Advances","volume":"17 ","pages":"Article 100255"},"PeriodicalIF":2.9,"publicationDate":"2024-11-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142759710","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In-situ measurements reveal debris thickness ranging from 0 to 70 ± 0.25 cm. Modelled debris thickness ranges from 0 to 64 ± 1.75 cm. Debris thickness pattern is such that it increases from centre to margins and snout to upglacier.

Modelled debris thickness showed a moderate positive correlation (r = 0.66; <em>p</em> &lt; 0.05) with surface lowering, indicating reduced melt under thick debris. These moderate-to-good correlations in both cases can be ascribed to the inability of coarse resolution data to capture small supraglacial feature variations.

This park was first suggested in 1973 to safeguard its great biodiversity, including the endangered Mountain Nyala (<em>Tragelaphus buxtoni</em>) and Red Foxes. Despite these conservation measures, the lack of infrastructure and the enormous area projected have resulted in significant wildlife habitat fragmentation. The purpose of this study is to analyse the habitat suitability of the Mountain Nyala in Bale Mountains National Park using GIS and remote sensing approach in order to inform conservation efforts and assist park management seekers in making policy decisions. To identify potential habitats for the Mountain Nyala, the study employed GIS spatial analyst techniques such as the Digital Elevation Model (DEM) and Landsat 9 (OLI/TIRS) data, as well as key environmental factors such as vegetation types, soil types, topographic factors (elevation and slope), climate factors (temperature), and proximity factors (distance to settlements, roads, and rivers). The Weights of these factors was calculated using IDRISI32 Multi-Criteria Evaluation (MCE) with the pair-wise comparison method. These weighted factor maps were then integrated through weighted overlay analysis to model wildlife habitat suitability. The analysis revealed five classes of habitat suitability; of the total land area studied, 1326.7 km<sup>2</sup> (60%) was deemed suitable for the Mountain Nyala while 881.3 km<sup>2</sup> (40%) was unsuitable. Specifically, 327.4 km<sup>2</sup> (15%) was classified as highly suitable, 240.7 km<sup>2</sup> (11%) as moderately suitable, 758.6 km<sup>2</sup> (34%) as marginally suitable, 352.4 km<sup>2</sup> (16%) as currently not suitable, and 528.9 km<sup>2</sup> (24%) as permanently not suitable.

Eleven key environmental and geological components— height, slope, lithology, soil type, and land use—were studied. After field research and Google Earth photos, 342 landslide incidents were collated and separated into validation (30%) and training (70%) datasets. ROC curves provide a technique for analyzing the efficacy of the FR and AHP models. With an Area Under the Curve (AUC) value of 83.4%, the AHP model exhibited superior accuracy than the FR model, with an AUC value of 74.4%. Very low, low, moderate, high, and very high vulnerability are five categories defined as landslide hazard zones. The AHP model assessed 10.5% of the area as very high risk, 19.8% as high danger, 25.6% as moderate risk, 28% as medium risk, and 16.1% as very low risk.

The results reveal that slope angle, lithology, and elevation are key factors impacting landslide vulnerability.
