Seismologists Monitor North Korea Nuclear Blast


North Korea this month set off its third nuclear test device of the past decade. And like the previous tests, this one created vibrations in the earth that could be detected around the world. Now, seismologists - scientists who normally study earthquakes - are analyzing the explosion's impact. VOA’s Bernard Shusman reports from Palisades, New York. Video was edited by Daniela Schrier
