Southern New Zealand earthquake data with SOSA network for J. Geophys. Res. 2024JB030371

This archive has data from the paper, “Deep and clustered microseismicity at the edge of southern New Zealand's transpressive plate boundary” (Williams et al., 2025; JGR 2024JB030371). The research presented in this paper determines and interprets hypocenters across Southland (Figure 1).  The catalog of events detected by SOSA and all phase arrival observations used in this research, including SOSA, Fiord22, and Geonet data, are provided in this archive.

Hypocenters are in the Simul hypocentre file with X,Y coordinates, error parameters and quality code.
