North Korea has detonated its first hydrogen bomb, which the North Korean state television officially announced. If it turns out to be true, the Hermit Kingdom takes a considerable leap toward the country's militaristic aspirations.
Compared with plutonium weapons, a hydrogen bomb is more impressive in terms of power.
"If there's no invasion on our sovereignty we will not use nuclear weapon. This H-bomb test brings us to a higher level of nuclear power," North Korea's state news agency says.
To illustrate how strong the bomb is, the U.S. Geological Survey observed a magnitude 5.1 earthquake east-northeast of Sungjibaegam, which is 12 miles away from the test site.
The measurement of the seismic occurrence is on par with the 2013 atomic bomb test, and it's estimated to be 100 times more powerful than the atomic bomb deployed in Hiroshima in 1945.
Back in December, the leader of North Korea Kim Jong-un first declared that the country had the technological resources to create a thermonuclear weapon. In response, the White House doubted North Korea's claim, and experts said that even though it's possible, it would be quite a feat for the reclusive country to pull off.
"North Korea appears to have had a difficult time mastering even the basics of a fission weapon, starting with a first test of apparently less than one kiloton and achieving only about 10 kilotons by its third nuclear test, seven years later," Bruce Bennett, a defense analyst at Rand Corp, says.
The United States wasn't able to immediately confirm whether or not it really was a nuclear test, but it's keeping an eye on the matter.
"We are aware of seismic activity on the Korean Peninsula in the vicinity of a known North Korean nuclear test site and have seen Pyongyang's claims of a nuclear test," John Kirby, State Department spokesperson, says.
Meanwhile, South Korea says North Korea violated the agreements with the United Nations Security Council to ban the development of nuclear weapons.
"This is a grave provocation to our security, threatening the survival and future of our nation and further directly challenging peace and stability in the world," South Korean President Park Geun-hye said during a National Security Council meeting held in Seoul.
Japan considered the event as a "grave threat" to the country's security, and it'll cooperate with countries such as the United States, China, Russia and South Korea.
China's response is considered as one of the most important denouncements, as the event has accentuated the country's inability to influence its ally's dangerous undertakings.
"Beijing formally protested, expressed concern over radioactive fallout in areas bordering North Korea, and indicated it would support new, punitive UN security council action as demanded by South Korea, among others," Simon Tisdall writes.
China Xinhua News has uploaded a video that shows how a school near the test site was affected by the event, where the staff and children had to evacuate because of the tremors.
In the meantime, the U.S. Republican presidential candidate Marco Rubio castigated the foreign policy of President Barack Obama.
"If this test is confirmed, it will be just the latest example of the failed Obama-Clinton foreign policy. I have been warning throughout this campaign that North Korea is run by a lunatic who has been expanding his nuclear arsenal while President Obama has stood idly by," Rubio says.
This marks the third explosion during Obama's presidential term, and by the look of things, the North Korean nuclear test would likely have an impact on the presidential campaign in the United States.
On the economical side of things, stock markets could drop in light of the recent event, as political instability affects the economy.
It appears that North Korea's hydrogen bomb test has unnecessarily stirred up the countries and would have an effect that traverses beyond the hermit country's neighbors.
