Description

0.2: Correction

This version corrects the original dataset which had some incorrect focal mechanisms. These mechanisms had incorrect rakes as a result of an error in the uncertainty calculation algorithm. The remainder of the catalogue is unchanged.

Description

Earthquake catalogue generated around the rupture area of the 2016 M7.8 Kaikoura earthquake. For a full description see the associated paper submitted to JGR 2021.

The catalogue is here in two forms:

  1. A QuakeML file with all picks, magnitudes, and locations included. This is quite a large file. When reading using ObsPy this will take a long time to read (>10 minutes), and expand in memory to > 8GB.
  2. A CSV file with the preferred origin and magnitude information for all events. Relocated events can be identified because they have a station count of 0: GrowClust does not return the number of stations used, whereas NonLinLoc (used for absolute locations) does.
