A comprehensive earthquake source database for China’s strong-motion flatfile (2007–2020)
The National Strong-Motion Observation Network System of China has collected over 12 000 strong-motion recordings from 2007 to December 2020. This study assembled the source-related metadata of 1 920 earthquakes associated with assembled well-processed recordings of China. The earthquake basic infor...

| description | The National Strong-Motion Observation Network System of China has collected over 12 000 strong-motion recordings from 2007 to December 2020. This study assembled the source-related metadata of 1 920 earthquakes associated with assembled well-processed recordings of China. The earthquake basic information, focal mechanisms, and the fault geometry were collected from various institutes and literature. We recommended the MW values for 900 earthquakes, the fault types for 1 064 earthquakes, and the fault geometries for 18 large earthquakes. We also performed the statistical analysis for establishing the empirical conversions of MW-MS, and ML, and providing the empirical relationships between MW and ruptured area, aspect ratio, respectively. Moreover, the ruptured fault geometries of large earthquakes were used to preliminarily divide all earthquakes considered into 1 141 mainshocks, and 779 aftershocks. The finite-fault distances (RJB and Rrup) of strong-motion recordings from the 18 large earthquakes were calculated, and then used to yield the statistic relationships between the point-source distances (Repi and Rhyp) and finite-fault distances. We finally provided the earthquake source database freely accessible at website. The source-related metadata can be directly applied to develop the ground motion prediction equations of China. |
