False positives are common in single-station template matching
Seismica Seismica 2:2 (2023)
Abstract:Template matching has become a cornerstone technique of observational seismology. By taking known events, and scanning them against a continuous record, new events smaller than the signal-to-noise ratio can be found, substantially improving the magnitude of completeness of earthquake catalogues. Template matching is normally used in an array setting, however as we move into the era of planetary seismology, we are likely to apply template matching for very small arrays or even single stations. Given the high impact of planetary seismology studies on our understanding of the structure and dynamics of non-Earth bodies, it is important to assess the reliability of template matching in the small-n setting. Towards this goal, we estimate a lower bound on the rate of false positives for single-station template matching by examining the behaviour of correlations of totally uncorrelated white noise. We find that, for typical processing regimes and match thresholds, false positives are likely quite common. We must therefore be exceptionally careful when considering the output of template matching in the small-n setting.
Strategies for making geoscience PhD recruitment more equitable
Nature Geoscience Springer Nature 16:8 (2023) 658-660
Abstract:Admission to doctoral study is a crucial step in the academic pipeline, but discriminatory procedures can disproportionately impact students from ethnic minority backgrounds. We show how these policies contribute to inequity in the geosciences and propose strategies for change.
