The NFA issued the order about two hours after the blaze began around 2 p.m. on Mount Hamji in the city, some 230 kilometres southeast of Seoul, and was spreading toward nearby villages.

Under the emergency order, the fire authorities have mobilised 28 additional fire engines to aid efforts to extinguish the blaze on top of 67 fire engines and 29 fire helicopters that had already been in operation, according to the officials.

No casualties have been reported so far, but nearby residents have been instructed to evacuate to local elementary schools, reports Yonhap news agency.

Acting President Han Duck-soo also ordered related authorities to "use all available equipment and personnel" to extinguish the fire and help people evacuate to safety.

"As the wildfire is spreading rapidly due to strong winds and there are residential areas nearby, make sure to take all necessary measures for emergency rescue and evacuation to prevent any loss of life," he said.

The Korea Forest Service also issued a Level 3 wildfire response, the highest in its three-tier scale, as strong winds continued to spread the flames.

A Level 3 response is issued when wind speeds exceed 7 metres per second, the expected damage area is over 100 hectares and firefighting efforts are expected to last over 24 hours.

As of 6 p.m., some 57 hectares of land had been affected by the fire, with the containment rate remaining at 14.5 per cent, according to fire authorities.
