A South Korean official said there was a “high possibility” that North Korea had tested a nuclear weapon, South Korea ’s Yonyap news agency reported. The magnitude 5.1. earthquake was detected by the U.S., China , Russia and South Korea , the news outlet reported. South Korea ’s defense ministry said Pyongyang could launch missiles and detonate a nuclear device simultaneously, Yonhap reported. The tremor was recorded at 11:57 a.m. local time. North Korea ’s Punggye-ri nuclear test site nuclear test site is located in the northeastern part of the country. Recent satellite photographs of the site showed that it was in a state of readiness and a test could be conducted within weeks of an order being given, according to an analysis by 38 North, a program of the School of Advanced International Studies ’ U.S.-Korea Institute. A nuclear test would generate seismic shockwaves similar to an earthquake, sound waves and, if the test site is not properly sealed, a spike in levels of radiation. All of this could be easily detected by an extensive global network of seismic, infrasound and radionuclide monitoring technologies. North Korea last month threatened to conduct a third nuclear test and launch more long-range rockets. Its rhetoric was in retaliation for a new U.N. resolution that reprimands Pyongyang for launching a rocket in December and imposes new sanctions. Pyongyang gave no timeline for carrying out a nuclear test. In October of 2006, the International Monitoring System, a worldwide network of technology that helps verify compliance with and detect violations of the Comprehensive Nuclear Test-Ban Treaty, easily detected Pyongyang’s relatively low-yield nuclear explosion. North Korea ’s second nuclear test, in May of 2009, was confirmed by seismic shockwaves. However, no radiation was detected. Analysts say this may have been because the explosion took place very deep underground. Read more: washingtontimes.com
