The rise, collapse, and compaction of Mt. Mantap from the 3 September 2017 North Korean nuclear test
Abstract
North Korea conducted its sixth underground nuclear weapons test in September 2017. The seismic waves generated from the test allow for triangulation and explosive yield estimates. However, Wang et al. show that synthetic aperture radar (SAR) should be added to the arsenal of techniques used to detect and characterize nuclear tests. SAR tracks deformation from space, which resulted in a better constraint of source parameters by using deformation from the nuclear test and the subsequent collapse of Mount Mantap. The test occurred at a depth of about half a kilometer, with an explosive yield around 10 times that of the Hiroshima explosion.
