Roundup of Global Volcanic Activity - Ongoing Activity for the week of 21 December-27 December 2016

Kilauea | Hawaiian Islands (USA) : During 21-27 December HVO reported that the lava lake continued to rise and fall, circulate, and spatter in Kilauea’s Overlook vent, and was visible from the Jaggar Museum overlook. Webcams recorded incandescence from long-active sources within Pu'u 'O'o Crater and from a vent high on the NE flank of the cone. The 61G lava flow, originating from a vent on Pu'u 'O'o Crater's E flank, continued to enter the ocean near Kamokuna at the easternmost lava delta. An active branch of 61G remained active E of Pu'u 'O'o and advanced slowly E at a rate of only a few tens of meters per day.

Sabancaya | Peru : Based on webcam and satellite views, the Buenos Aires VAAC reported that during 21-26 December intermittent, strong ash puffs from Sabancaya rose 6.4-7.6 km (25,000-28,000 ft) a.s.l. and drifted in multiple directions.

Sheveluch | Central Kamchatka (Russia) : KVERT reported that during 10-16 December lava-dome extrusion onto Sheveluch’s N flank was accompanied by strong fumarolic activity, dome incandescence, ash explosions, and hot avalanches. Satellite images showed a daily thermal anomaly over the dome, and ash plumes that drifted 370 km NNW during 16-20 December. A webcam recorded an explosion on 19 December with an ash plume that rose 7 km a.s.l. The Aviation Colour Code remained at Orange.

Sinabung | Indonesia : Based on PVMBG observations, webcam views, and satellite images, the Darwin VAAC reported that on 21-22 and 26-27 December ash plumes from Sinabung rose 3.3-6.2 km (11,000-20,000 ft) a.s.l. and drifted SE and NW.
