Features: This report compiles the seismic observation reports from the near-field digital observation network in Yunnan for the 6.2 and 6.1 magnitude earthquake sequences in Dayao in 2003, along with the catalog of modern seismic parameters (such as seismic moment Mo, short magnitude Mw, stress drop △σ, source rupture radius r, and source corner frequency fo), as well as the corresponding seismic waveform data. It represents an exploratory study on the catalog of modern seismic parameters and can serve as foundational material for scientists conducting related research. Currently, there are still many issues to discuss regarding the definition of the "catalog of modern seismic parameters," and the calculation of source parameters is limited by the use of source models. Addressing such problems requires further in-depth research and understanding of scientific questions such as earthquake theory, source mechanisms, Earth's interior characteristics, and seismic wave propagation. Digital seismic observation and digital seismic research are important development directions in the international field of seismology today. The construction of the national digital seismic observation network and regional digital seismic observation network during the "11th Five-Year Plan" period will significantly improve China's seismic observation quality, promote the widespread use of digital observation data, and facilitate in-depth regional studies on earthquake mechanisms and prediction. This report takes a significant step in domestic research on new seismic parameters and the establishment of catalogs of new seismic parameters. It is believed that it will play a positive role in promoting future related research efforts.
