my country releases the world's first large-scale seismic wave model with hundreds of millions of parameters, 'Truting”

News from this site on July 29, under the guidance of the Chengdu Municipal Science and Technology Bureau, the Chengdu Municipal Economic and Information Technology Bureau and the Municipal New Economic Development Committee, and sponsored by the National Supercomputing Chengdu Center and the Institute of Geophysics of the China Earthquake Administration, the "Tingting Large Model" was released "Meeting" was successfully held in Chengdu yesterday. At the meeting, the "True Listen" large-scale seismic wave model was officially released, marking a solid step forward for China in key technologies such as earthquake monitoring, early warning and precursor identification. This large model was jointly developed by the National Supercomputing Center in Chengdu, the Institute of Geophysics of the China Earthquake Administration, and Tsinghua University. It is the first large seismic wave model with hundreds of millions of parameters.

Experience in large model development.
Dr. Xiao Zhuowei from the Institute of Geology and Geophysics of the Chinese Academy of Sciences demonstrated on-site an example of using large models for foreshock identification and early warning. Mr. Zhao Ming, an associate researcher at the Institute of Geophysics of the China Earthquake Administration, introduced the application and prospects of large models in aftershock identification. .
Chen Shi, deputy director of the Institute of Geophysics of the China Earthquake Administration, said that the "True Listening" large model relies on massive data from the China Earthquake Observation Network and uses advanced artificial intelligence technology to significantly improve the accuracy and speed of seismic signal recognition.
In the short term, the "True Listen" large-scale seismic wave model will be used in fields such as seismic signal identification, seismic activity monitoring, and rapid response to major earthquakes. In the long run, seismology is an observational science, and major breakthroughs often come from a deep understanding of observational data. At present, neither traditional methods nor small and medium-sized models can make full use of terabyte and petabyte-level seismic observation data, and these data contain many important seismological issues. Therefore, the "Tingting" large seismic wave model is expected to bring major breakthroughs to earthquake scientific research in the long term.

"Diting" seismology AI training data set

According to reports, the "Diting" data set is the first in China, and it is also the largest, most comprehensive sample type and annotation of seismology professional AI training at home and abroad. One of the data sets.

Model Progress

Currently, the model is ready for use. The billion-parameter version is expected to complete pre-training in August 2024, providing scientific and technological support for the modernization of earthquake prevention and disaster reduction in the new era.

Application scenarios

In the future, this model can also be used for:

1. mine earthquake monitoring
2. shale gas mining
3. urban underground space structure detection
4. undersea earthquake monitoring
