The depth of the earthquake was 5 kilometers (3.1 miles). This is usually a sign that Pyongyang has conducted a nuclear test. However, for the moment natural or human-made for earthquake cause was not concluded. Two earthquakes had been detected. The analysis indicated neither one was man-made, meaning they don’t appear to be explosions.
The locations are around 50 kilometers away (more than 30 miles) from the site of previous nuclear tests. “We assess that there is a slim possibility that it was caused by a collapse,” said Park Jong-shin, one South Korean official said. China’s earthquake administration said it was a magnitude 3.4 earthquake and cited a “suspected explosion.” North Korea’s foreign minister said this week that his country could test a powerful nuclear weapon over the Pacific Ocean in response to President Donald Trump’s threats of military action. North Korea’s state-run Korean Central News Agency published articles Saturday with comments slamming Trump. “Trump’s rubbish is the open declaration of war against our supreme dignity, state, social system and people, and an unpardonable extra-large provocation,” was an affirmation in the content.
