CMT Catalog Files

CMT Catalog in ASCII format

The CMT catalog is available in the ASCII "ndk" format:

all events 1976-2020 (or gzip compressed).
monthly since January 1, 2005.
events in 1976 only.
Some solutions are also available for deep earthquakes in 1962-1976 and
intermediate-depth earthquakes in 1962-1975.
The January, 2010, Haiti mainshock/aftershock sequence, and events prior to 2010

Note that the "ndk" format is slightly different from the older "dek" format. Please see the description of the ndk format.

Quick CMTs: Quick CMT solutions are available in the "ndk" format individually or as a single file.
