South Korea's military is on high alert as North Korea might stage another provocation to celebrate its key anniversary next week government officials said Friday.

North Korea appears to be ready to carry out another nuclear test or launch a ballistic missile at any time given increased activities at its nuclear test and missile launching sites, military officials said. "Chances are high that the North will conduct its sixth nuclear detonation or test-fire a ballistic missile ahead of the anniversary of its ruling Workers' Party and the Security Consultative Meeting (SCM) scheduled in the U.S. later this month," a defense ministry official told Yonhap News Agency. 

The anniversary falls on Monday and defense chiefs of South Korea and the U.S. will discuss ways to ramp up the allies' three-stage deterrence strategy, which could involve a pre-emptive strike option, during the annual meeting in Washington, D.C., on Oct. 20. "Starting today, the military will maintain heightened vigilance against any provocations by the North," the official said. 

The unification and foreign ministries also said the government is fully prepared against provocations by the North and is fine-tuning contingency manuals tailored to each type of military provocation. The government then said continuing activity at tunnels No. 2 and No. 3 at the Punggye-ri test site in the communist state's northeast and giant canopies set up over entryways of these tunnels can indicate that another nuclear test is being prepared. 

Pyongyang conducted its fifth underground nuclear test in tunnel No. 2 last month, while no detonation has been carried out in tunnel No. 3. Commercial satellite imagery taken on Saturday of the test site "indicate continuing activity at all three tunnel complexes that could be used to conduct a nuclear test," the website 38 North monitoring the North said Thursday. 

The imagery shows a large vehicle, possibly a truck, near tunnel No. 2's entrance, while a large canopy in its parking lot, which has been present for the past two months, remains in place. There appear to be stacks of boxes near the area, it said. North Korea has conducted five nuclear tests in the past decade; two took place this year.
