North Korea's Nuclear Test Site Could Be Unstable

North Korea's Nuclear Test Site Could Be Unstable

When compared to the tremors registered during any of North Korea's previous nuclear tests, the authorities said that the strength of Friday's quake was much lower.

North Korea's sixth and last nuclear test on September 3 was by far its largest.

In a meeting with the Russian news agency TASS, Yong Ho said that North Korea will make the USA pay with a hail of fire, and that the country's nuclear program guarantees peace and safety in the region.

Shortly afterward, Kim accused Trump of being mentally deranged and said he would "pay dearly" for making threats against North Korea. This second tunnel may have caved in after the sixth test, the intelligence officials said.

South Korean experts at the time said publicly that the previous quake could have been a tunnel collapse.

"The explosion from the September 3 test had such power that the existing tunnels within the underground testing site might have caved in", Kim So-gu, head researcher at the Korea Seismological Institute told Reuters.

The Asian nation's foreign minister, Ri Yong-ho, told reporters in NY on September 22 that North Korea may retaliate for Trump's threats by testing a hydrogen bomb in the Pacific Ocean.

The tremor hit at 1:41 a.m. (1641 GMT) with a depth of around 5 km, the U.S. Geological Survey said, with the epicentre located north of the Punggye-Ri testing site. "If it goes ahead with another test in this area, it could risk radioactive pollution". In 2006, North Korea's first detonation triggered a 4.1-magnitude quake.

"The recent small quakes suggest that the test might have triggered crust deformation". Worries about a potential military clash between the US and North Korea have also intensified in South Korea and elsewhere, with President Donald Trump and North Korean leader Kim Jong Un exchanging crude personal insults and warlike rhetoric.

Arms experts say detonating a nuclear-tipped missile over the Pacific Ocean, while seen as the logical final step to prove the success of its weapons program, would be extremely provocative and carry huge risks.

"Beyond that, there will be no conversations with North Korea at this time", she added. An analysis of commercially available satellite imagery by Washington-based 38 North-a project of John Hopkins University focused on North Korea-noted the damage. Since North Korea began testing its nuclear capabilities, experts have debated whether explosions at Punggye-ri could trigger another volcanic eruption.
