Accounting for earthquake rates’ temporal and spatial variability through least-information Uniform Rate Zone forecasts

P. Iturrieta, Matt C. Gerstenberger, Chris Rollins, Russ J. Van Dissen, T. Wang & D. Schorlemmer
The distribution of earthquakes in time and space is seldom stationary. In low-seismicity regions, non-stationarity and data scarcity may preclude a significant statistical analysis. We investigate the performance of traditional stationary Poisson forecasts (such as smoothed-seismicity models [SSM]), with applications in Probabilistic Seismic Hazard Assessment, in terms of the available training data. We design bootstrap experiments that use multiple pairs of consecutive training-forecast windows of a catalogue to: (i) analyse the lowest available training data...

Tangaroa voyage TAN2006 took place from 26 June – 17 July 2020, with an unscheduled port call in Wellington from 29 June – 1 July due to equipment problems. The voyage objectives focused on geophysical studies of seafloor pockmarks on the Chatham Rise, as well as possible pockmarks and contourite deposits in the Bounty Trough. We acquired ~800 km of 2D seismic data, ~500 km of which were in a dense grid designed for high-resolution...
