During 27 October to 1 November, volcanic activity at Tungurahua was at moderate levels, with several explosions producing plumes of gas, steam, and ash. On 27 October an explosion produced an ash column to a height of ~3.5 km above the volcano. During the evening ash fell in the towns of Baños, Runtún, and El Salado.

The eruption that began at Manam on 24 October continued through at least 31 October. According to RVO, during 27-28 October there were occasional emissions of ash-laden brown clouds and projections of incandescent lava from Manam's Southern Crater. Fine ash from the eruptions traveled NW, and was deposited between the villages of Jogari and Baliau. Read all- More about Manam volcano

According to scientists from the Institute of Earth Sciences at the University of Iceland and the Icelandic Meteorological Office, an eruption began at the subglacial Grímsvötn volcano on 1 November around 2100. The eruption was preceded by both long-term and short-term precursors, and was triggered by the release of overburden pressure associated with a glacial outburst flood (jokulhlaup), originating from the Grímsvötn subglacial caldera lake.

Volcanic and seismic activity at Soufrière Hills continued to be at elevated levels during 22-29 October. The seismic network recorded one volcano-tectonic and 40 hybrid earthquakes. Like the previous week, the increased hybrid earthquake activity was thought to be related to heavy rainfall during the report period. Read all- More about Soufriere Hills volcano

During 28-29 October, weak-to-moderate explosions occurred at Santa María's Santiaguito lava-dome complex, producing gas-and-ash plumes to ~800 m above the volcano. Some explosions were followed by collapses of the lava dome in the crater of Caliente dome. Pyroclastic flows traveled down the volcano's NE and SW flanks after some collapses.

According to CVO, during 28 October to 1 November, seismicity at St. Helens remained at a low level compared to early in the unrest. The seismicity during the report period was consistent with a continuing, slow rise of magma driving uplift of the crater floor and feeding a surface extrusion of lava.

AVO lowered the Concern Color Codeat Veniaminof on 26 October from Yellow to Green. Seismicity, which had been associated with ash emissions that occurred during the summer of 2004, decreased to levels that indicated ash, ash-and-steam, or steam emissions were no longer occurring on a regular basis. Since early September, no ash emissions were seen on the web camera and no evidence of ash was visible on satellite imagery. Read all- More about Veniaminof volcano

During 21-26 October, the new lava dome inside the emerging dome of St Helens continued to grow, and seismicity remained at low levels compared to early in the unrest. Geological and thermal-imaging observations on 20 October confirmed that both the area of uplift, and the new lava extrusion increased in size noticeably since last seen on 14 October. In addition, the area of uplift and intense deformation continued to move southward and was nearing the crater wall. Read all- More about Mount St. Helens volcano

Based on information from JMA, a pilot report, and satellite imagery, the Darwin VAAC reported that an eruption began at Manam on 24 October around 1125, producing a plume to a maximum height of about 15 km (a height of ~6 km was reported in news articles). Preliminary reports from RVO stated that pyroclastic flows traveled down the valley SE of the volcano. The aviation color code was at Red, the highest value. Read all- More about Manam volcano

Seismic activity at Soufrière Hills was at elevated levels during 15-22 October in comparison to previous weeks. The seismic network recorded four rockfall events and 49 hybrid earthquakes, and one volcano-tectonic earthquake. MVO scientists thought that increased hybrid earthquake activity was related to heavy rainfall during the week. Read all- More about Soufriere Hills volcano
