Colima | Mexico | 19.514°N, 103.62°W | Elevation 3850 m

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.

Tengger Caldera | Eastern Java (Indonesia) | 7.942°S, 112.95°E | Elevation 2329 m

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.
