Abstract: In order to address issues such as the lack of comparability of geohazards susceptibility assessment results at the same level and inconsistencies across multiple levels, and to effectively support the delineation of geohazards susceptibility zones at the national, provincial, municipal, and county levels, the following approach has been adopted. Based on a multi-level evaluation and constraint indicator system for geohazards susceptibility, this initiative leverages key technologies—including integrated management of massive spatio-temporal data, cloud-based spatio-temporal computing frameworks, and intelligent dynamic caching with real-time access for multi-modal geospatial big data. It develops a comprehensive digital system for susceptibility assessment and zoning. This system digitizes the entire workflow, from constructing an indicator repository and automatically extracting multi-level evaluation units to performing multi-level assessments, anchor calibration at each level, aggregating results, and automated verification. The replicable and scalable system facilitates computational support for multi-level geohazards susceptibility evaluation. The system is designed for replicability and scalability.
