The international defence community is on alert today, with some suspicion that North Korea may conduct another weapons test due to the auspicious date for the country.
Today, October 10, marks the 77th anniversary of the ruling Worker's Party regime for North Korea.
The date also coincides with the US holiday of Columbus Day, which has some experts wondering whether the secretive state could conduct a new test.
The country has previously conducted tests on auspicious dates, including testing its first nuclear bomb on this date in 2006.
North Korea claimed to have tested a hydrogen bomb just over a month ago on September 3, when a magnitude 6.3 earthquake was registered by the United States Geological Survey near the Punggye-ri test site.
Provisional estimates suggest the explosion was in the range of 70-280 kilotons - many times greater than the explosion at Hiroshima, which had a yield of about 15kt.
The regime has also claimed its thermonuclear bombs can be loaded onto intercontinental ballistic missiles (ICBMs).
It has repeatedly conducted ICBM testing by firing missiles into the sea off its coasts, with one missile passing over Japan this year.
The United States has stepped up its condemnations of the weapons tests in recent months, with President Donald Trump not shying away from threatening war on the country if it attacks first.
