Spanish authorities today ordered the evacuation of four villages in the Canary Islands’ Tenerife after a forest fire broke out in a natural park around the Teide volcano.

The fire, which broke out yesterday evening on Tuesday, was raging in a wooded area in steep canyons in the north-east of Tenerife, making the work of firefighters more difficult.

“This fire has huge potential, we have asked for additional resources,” Rosa Dávila, president of the Tenerife council, told the local radio station. “It mainly affects the (National Park) Corona Forestal, there are a lot of pine trees and forest. It’s a rugged area and planes are essential.”

Water-dropping helicopters are flying over the area, Canarias Radio reported. The villages of Arate, Chivisaya, Media Montania and Ahafona have been evacuated, it said.

By early this morning, the fire had already burned about 1,300 hectares near the Teide volcano, Spain’s highest peak.

Last week, the Canary Islands were hit by a heatwave that left many areas “completely dry” and increased the risk of wildfires, as emergency services had warned.
