Two seismic events in North Korea unlikely man-made: CTBTO

Nuclear proliferation watchdog CTBTO said on Saturday it had detected two seismic events in North Korea on Saturday but they were probably not deliberate explosions in the isolated country.

"Two #Seismic Events! 0829UTC & much smaller @ 0443UTC unlikely Man-made! Similar to "collapse" event 8.5 mins after DPRK6! Analysis ongoing," CTBTO Executive Secretary Lassina Zerbo said in a Twitter post.

China's earthquake administration said it had detected a magnitude 3.4 earthquake in North Korea that was a "suspected explosion", while an official at South Korea's meteorological agency said the initial view was that it was a natural quake.
