Figure S1. Comparisons of Pn waveforms at selected stations for NKT3 (blue) and NKT2 (red). The vertical component seismograms are bandpass filtered between 2.0 and 10.0 Hz. The station name, cross-correlation coefficient (g), and traveltime difference (T) are labeled above each pair of waveforms.

Figure S2. The spectral ratios from individual stations and events for 3 North Korean nuclear explosions and 4 nearby earthquakes (parameters are listed in Table S2). The solid lines with circles are their network averages and shadows are standard deviations. Columns (A), (B) and (C) are for Pg/Lg, Pn/Lg, and Pn/Sn, respectively. In principle, the data from individual stations show scatters. The larger event show more consistent results than the smaller events. The earthquake data show larger scatters than the explosions, possibly because of complicated radiation patterns. The network averages effectively reduce scatters and are more reliable.
