「“Our monitoring stations picked up an unusual seismic event in the Democratic People’s Republic of Korea (DPRK) today at 03:30 (UTC). So far over 100 of our stations are contributing to the analysis. The event seems to have been larger than the one our system recorded in September last year and the location is very similar to that event. Our initial location estimate shows that the event took place in the area of the DPRK’s nuclear test site. ( 03-SEP-2017 03:30:06 LAT=41.3 LON=129.1 )」
