Fogo volcano (Cape Verde) - Smithsonian / USGS Weekly Volcanic Activity Report for 7 January-13 January 2015 (Continuing Activity)

The Observatório Vulcanológico de Cabo Verde (OVCV) reported that on 8 January the eruption at Fogo decreased in intensity; a small light-colored gas plume rose at most 100 m from the craters. Some explosions, following banging noises, were felt in areas 1 km away. Periodic explosions continued the next day and at 1530 a dark gas-and-ash plume rose 1.2 km and drifted SE.
On 10 January light-colored, dense plumes rose at 800-1,200 m. Explosions on 11 January produced light-colored gas plumes that rose as high as1.5 km. On 12 January gas-and-ash plumes rose 800-1,000 m.
In the afternoon a strong explosion was followed by smaller explosions and accompanying crashing noises that lasted for 2 hours. A very dense and dark-gray ash plume rose 2 km and drifted E, and was observed by people in S Philip and other parts of the island. At 1900 tephra was ejected 50 m above the crater.
The lava-flow fronts to the N and S of Ilhéu de Losna were stagnant, while a few outbreaks were observed in Portela and Bangaeira.
