Chinese state media have published a photograph of children at a primary school in Yanbian, a city near the North Korean border, who were evacuated from class following the suspected test.
The students were taken out of the building to avoid “potential danger,” reports say.

US 'monitoring situation'
The US National Security Council says it is monitoring the situation in Korea.
A spokesman, Ned Price, said:
We are aware of seismic activity on the Korean Peninsula in the vicinity of a known North Korean nuclear test site. We are monitoring and continuing to assess the situation in close coordination with our regional partners.

World powers react
There has been a lot of reaction to the possible nuclear test, which happened at 9.30am local time on Friday (1.30am BST).
Shinzo Abe, the Japanese prime minister, said the test “could not be tolerated” and that Japan would protest strongly to Pyongyang if confirmed, Reuters reported.
Japan's PM Shinzo Abe: Need to cooperate with U.S., other nations over N. Korea. Must lodge strong protest if N. Korea did nuclear test.
Japan’s chief cabinet secretary Yoshihide Suga told an emergency press conference on Friday morning that the government was acting swiftly to gather information.
We think that there is a possibility that this quake occurred because North Korea carried out a nuclear test.
Meanwhile, South Korea also believes the test – if proved – would be the North’s biggest ever, tallying with the view of US expert Jeffrey Lewis in the last post.

'North Korea's 'biggest test so far', says analyst
The 5.3 seismic event would indicate that North Korea has detonated its biggest nuclear device so far – if indeed it turns out to be a nuclear test, according to an analyst quoted by Reuters.
Jeffrey Lewis of the California-based Middlebury Institute of International Studies said the magnitude pointed to a 20- to 30-kilotonne yield. Lewis, using the North’s official title of the Democratic People’s Republic of Korea, said:
That’s the largest DPRK test to date, 20-30kt, at least. Not a happy day. Yield estimates are always kind of approximate. The point is that it is the biggest one to date unless they revise the yield downward.
For comparison, the initial analysis of North Korea’s January 2016 test estimated a yield of just 6 kilotonnes.
