On July 17th, former Minister of Geology and Mineral Resources and Head of the China Earthquake Administration, Song Ruixiang, led a delegation to Haidian and Changping districts to investigate Beijing’s earthquake prevention and mitigation efforts. Tang Jingjian, Secretary of the Party Leadership Group and Director-General of the Beijing Earthquake Agency, Deputy Director Liu Guiping, Deputy Secretary of the Party Committee and Director of the Beijing Institute of Geological Survey Technology, Liu Liangang, and Deputy Director-General Liu Shaomin also accompanied the visit.

The delegation inspected the Beiqing Road Earthquake Risk Exploration Project, the Nankou-Sunhe Paleoseismic Trench, a Disaster Prevention Engineering Site in Baishan Town. They reviewed the construction progress of the observation network, and the active fault line monitoring stations for geological hazard, and also reviewed the research value of the paleoseismic trench.

Song Ruixiang emphasized the importance of using radio-detectors for dense seismic observations, which enhances the accuracy of detecting stratigraphic structures and identifying Beijing’s seismic structures and major earthquake hazards. He highlighted the valuable collaboration between the Beijing Earthquake Agency and the Beijing Institute of Geological Survey Technology in constructing a cross-fault monitoring system using bedrock benchmarks. This partnership is crucial for studying tectonic movements and analyzing major earthquake trends in Beijing. He called for greater cooperation to create a platform for seismic and geological technological innovation, which could enhance the city’s earthquake prevention and mitigation capabilities.

Liu Liangang stated that the Beijing Institute of Geological Survey Technology would deepen its cooperation with the Beijing Earthquake Agency. They plan to conduct extensive research on surface deformation, quaternary period stratification, paleoseismic and neotectonic movements, and the impact of seismic and geological disasters. This comprehensive collaboration aims to strengthen the resilience and sustainable development of the capital city.

Relevant personnel from the Beijing Earthquake Agency, the Changping District Earthquake Bureau, and various departments of the Beijing Institute of Geological Survey Technology, including the Basic Geology and Geological Disaster Prevention Departments, participated in the investigation.
