China News Service:

In 2018, the CEA launched the China Seismic Experimental Site (CSES) project to study earthquake formation patterns in the country. Could you please provide an update on the progress of this project? How has its construction leveraged the supportive role of seismic science and technology, and how is it helping to modernize earthquake prevention and disaster alleviation? Thank you.

Wang Kun:

Thank you for your interest. The International Conference for the Decade Memory of the Wenchuan Earthquake was held on May 12. 2018. President Xi Jinping sent a letter to the conference, emphasizing the importance of scientifically understanding the laws of disasters and effectively reducing disaster risks. The central government also announced the construction of the CSES at the conference. The CEA's leading Party members group has firmly implemented the spirit of General Secretary Xi Jinping's letter, along with the disaster prevention, mitigation, and relief concept of "Two Commitments and Three Shifts." We are committed to integrating preventive efforts with disaster resistance and relief measures, while balancing regular mitigation and non-regular relief operations. This concept emphasizes a shift from post-disaster relief to pre-disaster prevention, from addressing single types of disasters to comprehensive mitigation, and from merely reducing losses to minimizing risks. Keeping in line with socioeconomic requirements and market rules and relying on science and technology, the CEA has strived to fulfill the overall goals of facilitating earthquake prediction, ensuring energy security, improving the resilience of cities, and mitigating disaster chains. Drawing on both domestic and international experiences, we are sparing no efforts to advance the construction of the CSES. 

The CSES is a major sci-tech infrastructure project to be constructed during the 14th Five-Year Plan period and the world's only seismic research facility focused on systematic studies of strong continental earthquakes. In 2023, the budgetary estimates were approved, and construction is now in full swing. The plan is to build 1,769 observation stations across Sichuan and Yunnan. These stations will monitor seismic activity, ground deformation, geochemical changes, and gravity fluctuations. Once completed, the CSES will be able to identify potential earthquake sources that may induce 6.5-magnitude or stronger earthquakes in block boundary belts. 

While constructing the CSES, we've insisted on delivering outcomes and providing services. Since 2018, the project has produced 15 scientific results, such as high-precision velocity structure models and Mohorovičić discontinuity models. We collaborated with the University of Science and Technology of China to launch the world's first AI-powered earthquake monitoring system, capable of accurately estimating earthquake source mechanism parameters within one second. We've also developed an AI-based automatic earthquake cataloging system, which triples the efficiency of manual work. We recently partnered with the National Supercomputing Center in Chengdu, Tsinghua University and other institutions to release the world's first large-scale seismic wave model with over 100 million parameters. These achievements provide crucial sci-tech support for enhancing smart earthquake monitoring and prediction, as well as modernizing earthquake prevention and disaster mitigation efforts.

We are prioritizing openness and cooperation in the CSES's construction and operation. Scientists from 13 countries, including the U.S., Russia, the Netherlands, Egypt, and Algeria, have contributed to the CSES's scientific research. Research universities, such as Peking University, the University of Science and Technology of China, and the Southern University of Science and Technology, have collaborated with the provincial governments of Sichuan and Yunnan in the construction of the project. Over 3,000 experts from China and abroad have attended the CSES annual conferences for exchanges in recent years, enhancing the project's academic influence. 

China aims to become the global leader in earthquake science and technology by 2035. To achieve this goal, Chinese seismologists will uphold and advance the scientific spirit, develop the CSES into a global hub for seismology and international cooperation in earthquake science and technology, as well as a global talent pool in this field. Efforts will be intensified to enhance China's self-reliance and strength in earthquake science and technology, facilitating Chinese modernization by providing high-standard earthquake safety services. Thank you.
