Trump announced new US sanctions on Thursday that he said allow targeting of companies and institutions that finance and facilitate trade with North Korea. It said the operation showed the seriousness with which it took North Korea's "reckless behavior." An official of South Korea's Meteorological Agency said acoustic waves should be detected in the event of a man-made earthquake. Tensions have continued to rise around the Korean Peninsula since Pyongyang carried out its sixth nuclear test, prompting a new round of UN sanctions. Trump told the UN on Tuesday the United States would "totally destroy" North Korea if it threatened the United States or its allies.
