BSL earthquake catalog available in database
December 19, 2003
The NCEDC is gradually converting the Northern California earthquake catalogs from "flat files" to a database structure. At present, the BSL BDSN catalog is transferred from 1984-present and the information is accessible through a search interface here:
As part of this conversion, the "flat file" search of the BSL catalog available here is no longer being kept up to date. Please access the new database search for access to the most current catalog from the BSL.
We are currently working to convert the USGS earthquake catalog to the database structure. This should be available in the next few months.
The NCEDC is a joint project of the University of California, Berkeley and the USGS. Please send us email at email@example.com or fill out our comments form if you have questions or comments about these changes.
