In La Reunion, the concerns are not linked to the eruption, but to the fires that have been raging since Saturday in the Mafate circus, and more particularly in Maïdo.

A thought by our friends from Réunion who are fighting against the fire, fueled by the wind and the drought.

The night went badly at Maïdo. Despite a relentless fight by the firefighters, the flames managed to cross the forest road around 2 a.m. in the night from Sunday to Monday. The balance sheet is now 200 hectares burnt.

The firefighters had to move their command post. The flames continue to spread towards the forest road of Tamarins and it is now an area of ​​500 hectares that is threatened.
