The new eruption continues, although only the lowest vent seems to be still active by now. It continues to feed a large lava flow now headed towards the vast coastal flat to the east. In the course of today, it reached the steeper section of the Enclos, the "Grandes Pentes" and started to descend there.

At this point, the lava flow, approx. 4-5 km long could be seen from the popular "lava road" (which might be closed off soon).
The lower fissure vent opened shortly after the first eruptive fissure had opened higher up on the flanks of Dolomieu crater, near the 1948 cinder cone "Chateau Fort". As is typical, the lower vent produced the more significant lava fountaining and lava flow effusion.
Compared to the last eruption in February, the current one seems to be much more intense. This could be explained if the eruption is fed by a deeper reservoir instead of a shallow pocket of magma (as was the case in February).
