IG reported that during the morning of 1 November three emissions of steam and ash were observed rising 1 to 2 km above Tungurahua's summit and drifting to the E and NE. According to the Washington VAAC, no ash was visible on satellite imagery at 0545, although any significant ash would have been visible. On 2 November there was a small increase in the number of long-period events and steam-and-ash emissions. Read all- More about Tungurahua volcano

Beginning on 26 October, seismicity at Soufrière Hills was at low levels until it increased on 1 November. Clear weather conditions allowed observations of the lava dome on 31 October and 1 November. The active lava dome had grown substantially and appeared to switch growth direction from the NE to the E, where a massive, near-vertical headwall had developed.

During 19-26 October there was a general reduction in volcanic activity at Soufrière Hills in comparison with the previous week, while seismicity remained at a similar level. The active lava dome continued to grow at a moderate rate, producing rockfalls and small pyroclastic flows in the upper reaches of the Tar River Valley. Cycles of mostly hybrid earthquakes, with a coincident increase in rockfalls, recommenced after weakening for about a week. Read all- More about Soufriere Hills volcano
