The earthquake occurred about 50km (31 miles) from a nuclear test site, monitors say. Previous quakes were caused by weapon tests.
- Chinese seismologists said it was a "suspected explosion" but South Korea says that it could be a natural quake not caused by a nuclear test.
The US Geological Survey (USGS), meanwhile, said it could not yet make a judgment as to the cause.
North Korea carried out a massive nuclear test on 3 September which was widely condemned at the UN.

China's seismic service CENC detected Saturday a zero-depth earthquake measuring 3.4 on the Richter scale in the Democratic People's Republic of Korea (DPRK).
ΑπάντησηΔιαγραφήThe epicenter is at 41.36 degrees north latitude, 129.06 degrees east latitude, according to the CENC.
The epicenter is roughly the same with a similar shallow earthquake on Sept. 3, which turned out to be caused by a nuclear test by the DPRK.
