2. Events and Nuclear Test Sites

Oral

Amplitude ratios between the first 2016 and 2013 North Korean nuclear tests for different kinds of seismic waves are compared. The observations show the first 2016 test had generated stronger Rayleigh waves with weaker short period P and Love waves in comparison with the 2013 test. Based on the observations, secondary seismic sources including the DC components caused by tectonic releases and...

2. Events and Nuclear Test Sites

Oral

We analyze seismic and infrasound signals generated by five underground nuclear tests in North Korea in 2006, 2009, 2013, and 2016 (January and September). Regional data from six seismo-acoustic arrays, cooperatively operated by Southern Methodist University (SMU) and Korea Institute of Geosciences and Mineral Resources (KIGAM) in the Korean peninsula, were used with two additional infrasound...
