Phys.org  February 7, 2024 Currently possible mis-classification of explosions as earthquakes currently limits the use of screening methods for verification of test-ban treaties. Researchers in Australia showed that populations of moment tensors for both earthquakes and explosions are anisotropically distributed on the hypersphere. They described a method that uses these elliptical distributions in combination with a Bayesian classifier to achieve successful classification rates of 99 per cent for explosions and 98 per cent for earthquakes using existing catalogues of events from the western United States. The 1983 May 5 Crowdie underground nuclear test and 2018 July 20 DAG-1 deep-borehole chemical […]
