A state of emergency has been declared in the farming and forest areas of Biobio and neighboring Nuble, prompting the deployment of troops and additional resources.
Interior Minister Carolina Toha said hundreds of homes had been damaged while there were 39 fires across the country.
“The conditions are going to get dangerous in the coming days,” Toha told reporters.
She said ground equipment and a fleet of 63 available aircraft were reinforcing firefighting, with help expected from Brazil and Argentina.
President Gabriel Boric cut short his summer vacation on Friday to travel to Nubal and Biobio, which have a combined population of about 2 million.
“My role as president today is to make sure that all resources are available for an emergency and that people feel that they will not be alone,” Boric told BioBio.
