An underground nuclear explosion was set off on 9 October 2006 in North Korea. The event was recorded at near regional to regional distances over purely continental paths by a network of broadband seismographs located along the northern edge of the Korean Peninsula. The event provided the first window of opportunity to make a reliable measurement of Lg-wave attenuation in northernmost North Korea, where the regional phase propagation characteristics are poorly known. The results of our analysis show Q0=317±14 and η=0.343±0.024, in close agreement with the corresponding values obtained of late using a completely different methodology and an independent set of seismic recordings in an adjacent region to the northwest, in southern Jilin, and in Liaoning provinces in China.
