Roundup of Global Volcanic Activity – New activity for the week of 16 November-22 November 2016

Copahue | Central Chile-Argentina border : Based on satellite and webcam images, the Buenos Aires VAAC reported that during 16-18 and 21-22 November diffuse steam-and-ash plumes rose from Copahue to altitudes of 3.3-3.6 km (11,000-12,000 ft) a.s.l. and drifted NE, ENE, E, and WNW. On 17 November OVDAS-SERNAGEOMIN reported that activity continued to be dominated by weak Strombolian explosions likely from a pyroclastic cone forming on the floor of El Agrio crater. The Alert Level remained at Yellow; SERNAGEOMIN recommended no entry into a restricted area within 1.5 km of the crater.

Kerinci | Indonesia : Based on satellite data, the Darwin VAAC reported that during 16-19 and 21 November ash plumes from Kerinci rose to altitudes of 4.3-4.6 km (14,000-15,000 ft) a.s.l. and drifted NE, ENE, SE, and S. Plumes drifted almost 30 km on 17 November.

Langila | New Britian (Papua New Guinea) : Based on analyses of satellite imagery and wind data, the Darwin VAAC reported that on 16 November an ash plume from Langila rose to an altitude of 4.3 km (14,000 ft) a.s.l. and drifted almost 30 km SE.

Sabancaya | Peru : The Technical and Scientific Committee for volcanic risk management of the Arequipa region (comprised of five groups including IGP’s OVS and INGEMMET’s OVI) reported multiple explosions at Sabancaya during 16-18 and 20-21 November, and ash plumes that rose 2-4.2 km above the crater rim and drifted more than 40 km N, NE, S, and SW. The Buenos Aires VAAC stated that ash plumes visible in satellite and webcam images drifted SE on 19 November.

Ubinas | Peru : The Comité Científico de Monitoreo Permanente del volcán Ubinas, made up of scientists from IGP’s Observatorio Vulcanológico del Sur (OVS) and INGEMMET’s Observatorio Vulcanológico (OVI), reported that at 1829 on 17 November an explosion at Ubinas generated an ash plume that rose 500 m above the crater rim and drifted W.

Zhupanovsky | Eastern Kamchatka (Russia) : KVERT reported that at 1429 on 20 November a webcam recorded ash plumes from Zhupanovsky rising to altitudes of 6-8 km (19,700-26,200 ft) a.s.l. and drifted 73 km E. The Aviation Color Code was raised from Green to Orange, the second highest level on a 4-color scale. KVERT noted that conditions were quiet after the eruption; on 22 November the Aviation Color Code was lowered to Yellow.
