Island authorities called for assistance in tackling the wildfire, which broke out at lunchtime on Wednesday and by Thursday morning and extra 67 firefighters and 32 vehicles, including water-dropping planes, were brought in from the mainland and neighbouring islands to help the 100 local workers control the blaze.
A 27-year-old German man was arrested by the CIvil Guard on suspicion of starting the fire, although it was not clear whether it had been a deliberate act of arson or accidental.
The blaze ravaged the Caldera de Taburiente National Park on the western-most island of the Spanish archipelago devouring ancient forest.
