Roundup of Global Volcanic Activity – Ongoing Activity for the week of 11 January-17 January 2017

Colima | Mexico : Based on webcam and satellite images, and the Mexico City MWO, the Washington VAAC reported that during 11-17 January ash plumes from Colima rose to altitudes of 4.1-6.4 km (15,000-24,000 ft) a.s.l. and drifted in multiple directions.

Dukono | Halmahera (Indonesia) : Based on analyses of satellite imagery, model data, and notices from PVMBG, the Darwin VAAC reported that during 11-17 January ash plumes from Dukono rose to an altitude of 2.1 km (7,000 ft) a.s.l. and drifted almost 300 km N, NE, E, and SE.

Kilauea | Hawaiian Islands (USA) : During 11-17 January HVO reported that the lava lake continued to rise and fall, circulate, and spatter in Kilauea’s Overlook vent. 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 at Kamokuna. Active surface flows near Pu’u ‘O’o advanced ESE; one branch was 2.4 km from the vent on 12 January.

Langila | New Britain (Papua New Guinea) : Based on analyses of satellite imagery and wind data, the Darwin VAAC reported that during 12-13 and 15 January ash plumes from Langila rose to an altitude of 2.1 km (7,000 ft) a.s.l. and drifted ESE and SE.

Nevado del Ruiz | Colombia : Based on information from Servicio Geológico Colombiano (SGC), the Washington VAAC reported that on 13 January an ash emission rose from Nevado del Ruiz to an altitude of 7 km (23,000 ft) a.s.l. and drifted N. Weather clouds prevented satellite views of the emission, and the webcam recorded gas-and-steam emissions with possible ash content.
