Description
255 landslides triggered by two major rainfall events in Changning, Baoshan, southwestern Yunnan Province, China, were identified and analyzed. The dataset, authored by Zongheng Xu and last updated in April 2026, integrates multi-scale spatial analysis, field investigations, and direct shear tests to examine distribution patterns and triggering mechanisms. It focuses on clustered landslides in metamorphic rock regions, with specific data on elevation, slope, lithology, and shear strength reductions.
Use Cases
Modeling landslide susceptibility based on topographic and lithological controls described in the study.
Analyzing the relationship between rainfall infiltration and shear strength reduction in shallow weathered layers.
Identifying high-incidence zones for clustered landslides based on elevation, slope, and aspect preferences.
Comparing landslide density on natural slopes versus areas near anthropogenic disturbances like roads.
Strengths
Contains data on 255 identified landslides from two specific rainfall events.
Includes geomechanical test results, such as direct shear tests showing reduced shear strength in shallow layers.
Provides specific spatial parameters for high-incidence zones (elevation 1860–1900 m, slopes 20°–40°, south- to southeast-facing aspects).
Limitations
Row count is unknown, which may limit suitability assessment.
Column-level documentation is absent; field semantics must be inferred after download.
The dataset is very small (5.5 KB), indicating a limited scope focused on a specific case study.
