Seismic waves equivalent to a 5.1-magnitude earthquake were registered near the Punggye-ri nuclear site in a remote area in the east of the country, rattling Chinese border cities.Hours later, state media announced the first "successfully performed" underground test on a hydrogen bomb.Nuclear experts have expressed some scepticism, saying they would have expected a larger blast from an H-bomb, but it could be weeks before independent tests can verify or dismiss the claim.This is the fourth nuclear test carried out at Punggye-ri - the previous ones were carried out in 2006, 2009 and 2013.“
