Eruption of Fogo volcano intensified on Saturday, December 6, and destroyed almost the whole village of Portela. According to news reports, the lava flow has now reached Bangaeira, a village downslope of Portela.
Authorities ordered full evacuation of the area, however, one of the main access roads was again destroyed by the lava flows making evacuations difficult.
The new lava flow advanced at about 30 meters per hour on Saturday. Compared to the slowly advancing lava from the last week, the current flow is much more fluid which makes the front of the new outbreak advance at a higher speed.
The island of Fogo consists of a single massive stratovolcano that is the most prominent of the Cape Verde Islands. The roughly circular 25-km-wide island is truncated by a large 9-km-wide caldera that is breached to the east and has a headwall 1 km high. The caldera is located asymmetrically NE of the center of the island and was formed as a result of massive lateral collapse of the ancestral Monte Armarelo edifice.

A very youthful steep-sided central cone, Pico, rises more than 1 km above the caldera floor to about 100 m above the caldera rim, forming the 2829 m high point of the island. Pico, which is capped by a 500-m-wide, 150-m-deep summit crater, was apparently in almost continuous activity from the time of Portuguese settlement in 1500 CE until around 1760. Later historical lava flows, some from vents on the caldera floor, reached the eastern coast below the breached caldera. (GVP)
