Based on webcam and satellite images, and information from the Mexico City MWO, the Washington VAAC reported that ash plumes from Colima rose to altitudes of 4.3-6.1 km (14,000-20,000 ft) a.s.l. during 5-6 and 8-11 October. Thermal anomalies were observed on most days; a strong hotspot consistent with lava flow was observed on 9 October.

Karymsky | Eastern Kamchatka (Russia) | 54.049°N, 159.443°E | Elevation 1513 m

Based on satellite image analysis, KVERT reported that during 5-7 October gas-and-steam plumes containing small amounts of ash rose from Karymsky and drifted 100 km SE. The Aviation Color Code was raised to Yellow. Ash emissions continued to drift SE on 8 October; the total length of the ash plume grew to 388 km. The Aviation Colour Code was raised to Orange.

Based on analyses of satellite images, the Darwin VAAC reported that during 5-6 October ash plumes from Tengger Caldera’s Bromo cone rose to an altitude of 2.7 km (9,000 ft) a.s.l. and drifted almost 40 km SW and W. On 7 October PVMBG reported that activity at Bromo cone remained high. Grayish-white and blackish-brown plumes rose 100-300 m above the crater rim and drifted NW.

Ulawun | New Britian (Papua New Guinea) | 5.05°S, 151.33°E | Elevation 2334 m

Based on analyses of satellite imagery and observations from RVO, the Darwin VAAC reported that during 11-12 October ash plumes from Ulawun rose to altitudes of 1.8-2.4 km (6,000-8,000 ft) a.s.l. and drifted 65 km WSW and W.
