According to Xinhua News Agency, a large-scale seismic wave model named "Ditian" developed jointly by the National Supercomputing Center in Chengdu, the Institute of Geophysics of the China Earthquake Administration, and Tsinghua University was officially launched in Chengdu, Sichuan. This model, the first in China to reach a scale of hundreds of millions of parameters, marks a significant breakthrough in the integration of seismological research and artificial intelligence technology.
Guo Li, Chairman of Chengdu Supercomputing Center Operation Management Co., Ltd., introduced that the "Ditian" project commenced in September 2023. After more than half a year of efforts, the research team successfully trained this large model using the first and currently the largest-scale seismological AI training dataset in China and abroad.

Chen Shi, Deputy Director of the Institute of Geophysics of the China Earthquake Administration, emphasized that large model technology is crucial for fully utilizing massive seismic observation data. He stated that the "Ditian" large model has significantly improved the accuracy and speed of seismic signal recognition.
Wang Jianbo, Executive Deputy Director of the National Supercomputing Center in Chengdu, pointed out that the "Ditian" large model is of great significance for breaking through the performance bottlenecks of small and medium-sized seismic wave models and enhancing the intelligent processing capabilities of seismic big data. The center is actively promoting the application of artificial intelligence technology in disaster prevention and mitigation, smart cities, and other fields.
It is reported that the "Ditian" seismic wave large model is currently available for use, and a version with a scale of billions of parameters is expected to complete pre-training by August 2024. In the future, the model is expected to play a significant role in various fields such as mine seismic monitoring, urban underground space structure detection, and submarine seismic monitoring, providing strong support for China's earthquake early warning and disaster prevention and mitigation efforts.
