Launch of 'Diting': The First Billion-Parameter AI Model for Earthquake Wave Analysis Using Extensive Training Datasets

On July 28, the "Listening" seismic wave model was launched in Chengdu, Sichuan. This groundbreaking model was developed through a collaboration between the National Supercomputing Center in Chengdu, the China Earthquake Administration's Geophysical Research Institute, and Tsinghua University. It represents the first seismic wave model with over 100 million parameters.

Guo Li, chairman of Chengdu Supercomputing Center Operations Management Co., explained that in September 2023, the center partnered with the Geophysical Research Institute to establish the "Joint Laboratory for Innovative Applications of Seismic Large Models." This initiative also includes collaboration with Tsinghua University and the Institute of Geology and Geophysics at the Chinese Academy of Sciences for training the "Listening" seismic wave model.

The "Listening" dataset stands out as one of China's first and largest AI training datasets in seismology, characterized by its comprehensive sample types and annotations. Over the past six months, researchers have successfully utilized this dataset to create the first seismic wave model surpassing 100 million parameters.

Wang Jianbo, executive deputy director of the National Supercomputing Center in Chengdu, emphasized that the "Listening" seismic wave model is crucial for overcoming performance bottlenecks in modeling small to medium seismic waves. It significantly enhances the capabilities for processing and mining large seismic data sets. The center is actively promoting the use of AI technology in fields such as disaster prevention and mitigation, as well as smart city development.

Currently, the "Listening" seismic wave model is ready for use, with a version containing one billion parameters expected to complete pre-training by August 2024. This versatile model will be applicable in various domains, including monitoring mining-induced seismic activity, detecting underground structural dynamics in urban areas, and conducting offshore earthquake monitoring.
