[Geology2] Volcanic activity worldwide 30 Nov 2014

Sunday Nov 30, 2014

The eruptive vents at Fogo this morning (MuzikaTV)

Fogo (Cape Verde): Although explosive activity has decreased at the vents, it seems that lava effusion picked up. The advance of some of the lava flow fronts in Portela village picked up again this morning, reaching 20 meters per hour. Local sources mention that seismic activity also increased.
If no changes occur, it seems that within a few days, the whole village of Portela could become a victim of the lava flows. Evacuation of remaining goods from the still standing, threatened buildings continue.
Most of the Nature Park has by now been covered by lava. The Park's Headquarters building, already damaged by lava flows and looting earlier on in the eruption, has now been completely destroyed.

Zhupanovsky (Kamchatka, Russia): Mild ash emissions continue. A plume at 14,000 ft (4.2 km) is drifting eastwards from the volcano.

Aso (Kyushu): Mild, but continuous ash emissions continued at least until this morning, and incandescence remains visible from the Nakadake crater.
Cloud cover prevented observations most of today.

Sakurajima (Kyushu, Japan): 3 strong explosions occurred during yesterday-today, producing ash plumes that reached up to 16,000 ft (4.8 km) altitude (Tokyo VAAC)

Colima (Western Mexico): An explosion occurred this morning and produced a plume that rose to approx 5 km altitude and drifted 80 km to the northeast before dissipating.
