Fogo volcano (Cape Verde) - Smithsonian / USGS Weekly Volcanic Activity Report for 31 December-6 January 2015 (New Activity / Unrest)

Based on gas-monitoring efforts of the Instituto Vulcanológico de Canárias (INVOLCAN) and data from the Toulouse VAAC, the Observatório Vulcanológico de Cabo Verde (OVCV) reported that sulfur dioxide emission rates at Fogo were 1,201-1,368 tons per day during 30-31 December and 1-2 January. A gas plume rose 700-900 m above the cone during 30-31 December and drifted N; on 31 December tephra was ejected 30-40 m away and ash was present on the plume. A lava front near S Ilhéu de Losna had been stagnant for a few days while one near the N part of the town advanced at a reduced speed, overtaking a road and parts of some housing.
Temperatures of the lava fronts continued to gradually decrease. During 1-2 January a gas plume rose 400-600 m above the cone and tephra was occasionally ejected 20-25 m away.
