Tremor detected near North Korea nuclear site

 

A earthquake has been detected in North Korea, close to a site previously used for nuclear tests.

China, Japan and South Korea have all said there are indications the tremor was man-made, meaning the North may have carried out a new nuclear test.
North Korean state media has said a "special, significant" announcement will be made shortly.
South Korean ministers are holding an emergency meeting, the Yonhap state news agency said.
North Korea is believed to have conducted three underground nuclear tests since 2006, all at a site called Punggye-ri.
The new tremor was detected about 50km (30 miles) from Punggye-ri at a depth of about 10km, according to the US Geological Survey.
The USGS said the quake had a magnitude of 5.1. South Korea's meteorological agency measured it at 4.2.
Japan's chief cabinet secretary Yoshihide Suga said that "considering past cases, there is the possibility that this might be a nuclear test by North Korea".
