Amidst fears that North Korea could have undertaken yet another nuclear bomb test, the South Korean experts have clarified that the tremors that erupted on Friday morning were due to natural earthquake and not due to explosion.
They asserted that a 2.9-magnitude earthquake struck near a site that was earlier used by North Korea for its nuclear test.
The tremor is said to have struck at 01:41 am (1641 GMT Thursday) with a depth of around five kilometres (three miles) and this was confirmed by US Geological Survey.
“This event occurred in the area of the previous North Korean nuclear tests.
The event has earthquake-like characteristics, however, we cannot conclusively confirm at this time the nature (natural or human-made) of the event,” the US agency said. But the Korea Meteorological Administration in the South said on its website that “analysis shows it was a natural quake”.
“It is believed to have caused no damage,” it added. It came three weeks after a 3.5-magnitude earthquake struck near the same area, with seismic experts and a UN nuclear test ban watchdog calling that tremor on September 23 a likely aftershock of the North`s sixth and largest nuclear test.>
