The eruption continues. A new lava flow that appeared last night is heading again towards the village of Portela, which it might hit in less than 2 days.

At the eruptive fissure, 3 vents seem to still be active and explosive activity has decreased a lot. The eruption continues to be dominated by lava effusion.
The large flow that covered part of Portela during the past days stopped yesterday, probably caused by a temporary (?) drop in effusion rate which in turn lead to the clogging of the tube that alimented it.
Authorities took the opportunity to try to open a fifth road through the lava flow in order to reach Portela and facilitate the transport of goods that remain to evacuate - mostly wine and food for livestock.
The new lava flow seems to follow the northeastern rim of the previous flow and its advance rate of the new flow was approx. 3 meters per minutes. Today, it was 1700 m from the village. At this rate, the lava might reach the village again in 1-2 days only. In addition, if the new flow continues to follow the margin of the previous flow, rather than expanding on top of it, it would "take a shortcut" to reach the village.
Another lava flow was reported this afternoon heading in the opposite direction, to the south towards Boca Fonte, likely following the margins of the 1995 flow.
