One man died in the fire and 35 others were injured, with at least a few thousands left displaced and damage piling up to what authorities have described as "an unprecedented extent."

The government declared a state of national disaster for the affected areas as of 9 a.m., enabling swift provisions of relief supplies and other resources necessary to minimize the damage.

President Moon Jae-in urged his government to make all-out efforts to contain the fire and help the victims. He told officials to consider designating the blaze-hit areas as special disaster zones. That would entitle the locations and their residents to speedy, special government support.

"I ask you to do your utmost until the very last moment when all embers are completely put out," the president said earlier in a crisis management meeting held at the national crisis management center at his office Cheong Wa Dae in Seoul.

Finance Minister Hong Nam-ki said the government has earmarked 4.25 billion won ($3.7 million) for emergency recovery efforts.

Given that the fire-hit regions are located near the inter-Korean border, the government shared information with North Korea about the fire and rescue efforts and expressed hope for bilateral cooperation if necessary, the Ministry of Unification said.

The military and police sent their forces to the scenes to help contain the fire.

The 8th Army Corps deployed 3,500 of its men and flew 10 military choppers to the sites. Over 1,700 police forces from 13 squads and guard units from Gangwon, Gyeonggi and central North Chungcheong provinces joined the forces to put out the fire.

The Ministry of National Defense set up a disaster control support team to help contain the fire, providing military choppers, fire engines and 16,500 troops.

As of 11:00 a.m., the blaze had burned 529 hectares, or 5.29 million square meters, of woodland and destroyed more than 200 houses and buildings, according to the estimates by the Gangwon control center.

The interior ministry said most of the fire in Goseong had been contained and more than 50 percent of the blaze in Inje and Gangneung was under control as of around noon.

The government's possible decision on special disaster zones will be up to the results of an assessment of damage scale.

The regions affected include the counties of Goseong, Inje and Sokcho, as well as Gangneung and Donghae cities. With the designation, they would be eligible for emergency funds and other assistance at the direction of the central government.

 

South Korea declared states of disaster in 2005 in the wake of a massive wildfire in Yangyang in the same province and in 2007 after South Korea's worst oil spill from a Hong Kong-registered tanker off the western coast of Taean.   

The fire, believed to have started on a roadside in the county in Gangwon Province, spread quickly to neighboring areas, engulfing Sokcho, Gangneung and Donghae farther south within hours, as strong southerly winds blowing at speeds of up to 35.6 meters per second fanned the flames.

Over 870 firetrucks and some 13,000 firefighters have been dispatched to the sites to put out the blaze, firefighters said.

More than 4,200 people have been forced from their homes. 

Among the damaged buildings are nursing facilities and commercial camping sites -- the eastern coastal cities are popular resort and travel destinations.

Roads and railways have been shut off, with 52 schools and other public facilities closed.

The authorities are processing the scene to figure out the exact cause of the blaze. They first suspected an explosion of equipment installed on a telephone post, as witnesses said they heard a blast.

After conducting a preliminary examination, the Korea Electric Power Corp. said the switch on the pole is unlikely to have exploded on its own, adding that it could have been a spark created from wires and dust in the very dry air.

Surveillance footage obtained by Yonhap News Agency from a nearby gas station showed sparks from a roadside switch gear instantly growing into a fire. The wires on the utility pole that were connected to the switch were swinging violently due to the high winds. (Yonhap)
