Oregon authorities said on September 10 that more than 500,000 people - more than 10% of the total of about 4.2 million people in the state - were forced to evacuate as unprecedented fires swept through.
The forest fire that broke out in the western United States killed at least 15 people, leveling some residential areas and forcing firefighters to fight extremely tense.
According to The Guardian, the particularly serious situation in Oregon has killed at least three people, destroyed five towns and forced communities to evacuate from the southern border to the outskirts of Portland.
On the evening of September 10 (US time), President Donald Trump declared a state of emergency in the state, providing federal assistance to help the locality fight the fire.
We have never seen such a major fire in the state, said Governor Kate Brown, adding that as of September 10, more than 364,000 hectares of land have been burned across the state in the past few days nearly double the damage from fire in a normal year.
The outbreak of fires across the region was fueled by dry winds and a record heat wave - fueled by widespread drought, which caused vegetation to wither. The Oregon Emergency Management Office has warned that fires will be even more dangerous in northwest Oregon as the heat and wind continue to occur.
Not only Oregon, Washington and California are also struggling to cope with the fire. In Washington, a one-year-old boy died after his family was burned down while evacuating from a forest fire. The state fire caused nearly 2,426km2 of damage, Governor Jay Inslee said on September 10.
California, which has faced a series of fires since August, has seen the first, third, fourth, ninth, 10th and 18th major forest fires in state history in the past few weeks, according to the National Weather Service.
In Butte County, northern California, at least 10 people have died and 16 are missing as the North Complex fire continues to affect, forcing about 20,000 people to evacuate.
On the morning of September 9, the scene of the sky turning orange and dark yellow in the San Francisco Bay area due to smoke from the fires spreading across California, the US and the western region surprised many people.
"We have seen how dangerous forest fires are over and over again. So I ask you to please prepare mentally, be aware of the situation and pay attention to warnings, said Butte County Sheriff Kory Honea.
