Volcanic activity worldwide 4 Feb 2015: Piton de la Fournaise volcano

Piton de la Fournaise (La Réunion): A new eruption has started at the volcano, following a brief seismic crisis that started early this morning.
According to OVPF, the new (fissure) vent should be located between Bory, Dolomieu and Rivals craters on the upper flank of the Dolomieu main cone. A lava flow is descending SSW and has already reached the base of the Dolomieu crater, i.e. the floor of the enclos. Its length is more than 1 km.
