Earthquake catalog for California and Nevada

Earthquake catalog combining events from California and Nevada from 1980 through September 2023. A concerted effort has been made to only list unique events (i.e., no duplicates across data sources) but it is impossible to guarantee that this has been accomplished perfectly. Similarly, we rely on hypocentral and magnitude efforts from each data center and do not attempt to relocate events or otherwise unify/homogenize the data in any way.

The columns in the text file are space delimited:
