Roundup of Global Volcanic Activity – Ongoing Activity for the week of 23 November-29 November 2016
Colima | Mexico : Based on satellite, webcam, and wind data, the Washington VAAC reported that on 26 November an ash plume from Colima rose to an altitude of 4.9 km (16,000 ft) a.s.l. and drifted 75 km W. The next day a gas plume with possible ash content rose to an altitude of 5.5 (18,000 ft) a.s.l. and drifted almost 20 km N. On 28 November an ash plume rose to an altitude of 5.2 km (17,000 ft) a.s.l. and drifted 13 km NE.
Dukono | Halmahera (Indonesia) : Based on analyses of satellite imagery, information from PVMBG, and model data, the Darwin VAAC reported that during 23-29 November ash plumes from Dukono rose to an altitude of 2.1 km (7,000 ft) a.s.l. and drifted NE, E, SE, and S.
Kilauea | Hawaiian Islands (USA) : During 21-29 November HVO reported that the lava lake continued to rise and fall, circulate, and spatter in Kilauea’s Overlook vent; the lake level rose as high as 6.5 m below the Halema’uma’u floor. A section of the wall of the Overlook Vent collapsed into the lava lake on 28 November. Webcams recorded incandescence from long-active sources within Pu’u ‘O’o Crater. 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. Breakouts at the upper part of the lava-tube system began on 21 November, sending lava as far as 500 m S and E. These breakouts, and others inland from the ocean entry, continued to be active through 29 November.
Klyuchevskoy | Central Kamchatka (Russia) : KVERT reported that a daily thermal anomaly over Klyuchevskoy was visible in satellite images during 18-25 November. The Aviation Color Code remained at Yellow.
