KMA has been operating infrasound array stations at Cheorwon(CW) and Yanggu(YG) since 2011. KMA’s infrasound stations successfully detected the azimuthal directions of the arrivals of the infrasound signals generated from DPRK’s underground nuclear explosions. Recently, we tested ray tracing simulation of infrasound wave propagation in the atmosphere generated from the calculation methods of...
We equalize regional P, surface, and the P+surface waves simultaneously to estimate reduced displacement potential (RDP) and depth of burial (DOB) of DPRK nuclear explosions, using waveforms from the stations at IRIS DMC. RDPs are predicted using the formula in Saikia (2017). The algorithm starts with the initial RDP and DOBs for two explosions. RDP of one explosion S1 is convolved with the...
The Source Physics Experiments (SPE) are a series of controlled chemical explosions at the Nevada National Security Site to gather observations to verify and validate explosions physics-based numerical models, and to understand, in particular, the genesis of shear waves to improve nuclear monitoring capabilities. Executed between 2011 and 2016, SPE Phase I included six chemical explosions...
