Small Quake Rattles North Korea Nuclear Testing Grounds, Not Manmade: South Korea

Small Quake Rattles North Korea Nuclear Testing Grounds, Not Manmade: South Korea

It was centred very close to North Korea's Punggye-ri Nuclear Test Site, which previous weapons tests have been detected at through the earthquakes they generate.

The tremor hit at 01:41 AM (local time) with a depth of around five kilometres, the US Geological Survey said, with the epicentre located north of the Punggye-Ri testing site.

Today (Thursday), a relatively weak 2.9 magnitude natural disaster was recorded near the North Korean town of Sungjibaegam.

We start in North Korea where a magnitude 2.9 natural disaster registered shortly after midnight, striking near the regime's nuclear test site.

"The event has quake like characteristics, however, we can not conclusively confirm at this time the nature of the event".

Friday's quake was a magnitude 2.7 with a depth of 3 km in North Hamgyong Province in North Korea, the Korea Meteorological Administration said. The seismic experts and a United Nations nuclear test ban watchdog had referred to the tremor on September 23 as an aftershock of the North's sixth and largest nuclear test.


"I think the Punggye-ri region is now pretty saturated". However, the South Korean experts have said that the tremor did not appear to be man-made.

And now the latest quake to hit the region suggesting the detonations have dramatically destabilised the area.

September's nuclear test was so strong that it shook buildings in Russian Federation and China and was described as a "perfect success" by North Korea's state-run media.

It was the latest in a string of aftershocks following North Korea's sixth nuclear test on September 3, which caused a 6.3 magnitude quake, according to the USGS. "The recent small quakes suggest that the test might have triggered crust deformation".

Another issue that could keep North Korea from using Punggye-ri for nuclear tests the nearby active volcano of Mt. Paektu, Yonsei University's Hong said.
