A 5.3 magnitude earthquake was detected in North Korea on Sept. 9 after it’s largest nuclear test with ballistic missiles.

The test was done in the northeastern parts of the country, only 50 miles away from China’s border. Experts believe the bomb ranges anywhere from 10 to 20 kilotons of TNT, which is around the range of the bombs dropped on Japan during WW2.  This is the fifth time North Korea has done nuclear weapon testing, and the state has demanded that the world “no longer denies the strategic position of our country as a nuclear weapons state.”

China and Japan have been monitoring the test site radiation levels with both having fear that the country will provoke war.

Japan’s Prime Minister Shinzo Abe said that “North Korea’s nuclear development is becoming a graver threat to Japan’s safety and severely undermines the peace and safety of the region and the international community.”

China fears the fall of North Korea due to aggression and bankruptcy, as the nation will likely fall, if it is to continue with this spending. Fortunately, China could cut its oil supply to North Korea, forcing the state to cut nuclear testing, according to the New York Times.

The dictatorship has had five UN sanctions since it’s first in 2006. The US, England and France have pushed for a 15-member body in the UN security council to put new sanctions and denounce North Korea’s decision to carry out the test.
