Southern California Earthquake Data Center

The Southern California Earthquake Data Center (SCEDC) operates at the Seismological Laboratory at Caltech and is the primary archive of seismological data for southern California. The 1932-to-present Caltech/USGS catalog maintained by the SCEDC is the most complete archive of seismic data for any region in the United States. Our mission is to maintain an easily accessible, well-organized, high-quality, searchable archive for research in seismology and earthquake engineering.

南加州地震数据中心（SCEDC）设于加州理工学院地震实验室，是南加州地震数据的首要档案馆。由SCEDC维护的1932年至现在的加州理工学院/美国地质调查局目录是美国任何地区地震数据的最为完备的档案馆。我们的使命是构建一个易于访问、组织严谨、质量上乘、可搜索的档案库，以供地震学和地震工程研究之用。
