Authorities resumed efforts at dawn on Tuesday to combat the massive wildfire that broke out on a mountain in the southeastern city of Daegu the previous day. 

The Korea Forest Service said it plans to contain the main blazes Tuesday, mobilizing 52 helicopters and more than 15-hundred people. 

According to forest authorities, 252 hectares of land are estimated to be within the affected zone and 82 percent of the fire was out as of 8 a.m.

The fire broke out around 2 p.m. on Mount Hamji within the city and quickly spread to nearby areas due to strong winds, prompting the issuance of a Level Three response alert at 6 p.m. 

Fire authorities estimate that about 660 people have evacuated due to the fire.
