This dataset summarizes the overall work of Task 9, Special Topic 1 over the past five years. The special topic has completed remote sensing interpretation of active faults within the survey area of the Qinghai-Tibet Plateau, conducted detailed investigations and studies on the activity of key faults and faults in critical regions, and carried out multiple route traverses and general surveys. Based on existing research results and data, a database and knowledge base for active faults and earthquake disasters on the Qinghai-Tibet Plateau have been established, and the Active Faults and Strong Earthquake Distribution Map (1:1,000,000) of the Qinghai-Tibet Plateau and its accompanying instruction manual have been finalized. The dataset also covers the collection and compilation of regional earthquake catalogs with magnitude ≥ M4.7, precise earthquake location and verification of the locations of moderate-strong earthquakes, as well as the establishment of a complete catalog of over 9,400 earthquakes with magnitude ≥ M4.7 within the region. Relying on modern geodetic technologies such as GNSS, leveling and InSAR, the regional strain field and stress field of the Qinghai-Tibet Plateau have been constructed, and studies on the current deformation status of multiple major boundary faults and critical regions have been carried out. For sudden strong earthquakes on the plateau, emergency scientific investigations and comprehensive research have been organized. While scientifically clarifying the seismogenic mechanisms of earthquakes and assessing the impact scope of earthquake damage, the work has provided scientific guidance for emergency rescue and post-disaster reconstruction, and proposed the main genetic mechanism for the frequent occurrence of strong earthquakes on the plateau in recent years. The outcomes of these scientific investigations support the scientific planning, design, construction, operation and maintenance of national strategies and major projects, providing scientific support and consulting services for major route selection, planning, construction and operational safety guarantee, while also offering critical support for urban planning, regional disaster reduction planning and other relevant fields. The contents of this dataset are available for reference and use by relevant researchers and engineering practitioners.
