Shiveluch (Kamchatka): Explosive activity continues. Volcanic Ash Advisory Center (VAAC) Tokyo warned about a volcanic ash plume that rose up to estimated 12000 ft (3700 m) altitude or flight level 120 and is moving at 20 kts in E direction.
The full report is as follows: POSS ERUPTION OBS AT 20221201/1630Z FL120 EXTD E OBS VA DTG:01/1730Z to 12000 ft (3700 m)
…1 Dec:
The extrusive eruption at the volcano continues to be elevated.
A massive block-and-ash flow took place from the volcano’s active lava dome on 29 November. The KVERT surveillance cameras observed a dense grey billowing ash plume (so-called phoenix cloud) separating from the pyroclastic density current. The VAAC Tokyo reported the ash column up to 13,000 ft (4,000 m) height. The reason for this flow was the gradual accumulation of unstable lava dome material and its destabilization, resulting in a partial collapse.
It came during the intense phase of the volcano over the past few weeks as the active lava dome continues to grow and produce frequent incandescent rock falls to the southeast and southeast.

Maunaloa (Big Island, Hawai’i): The USGS just published a fresh webcam image a while ago.
As was expected, traveling lava flows along the northeast slope started to spread out and inflate by hitting a low-sloping spot.

An updated USGS lava flow map displays its advance over the past 36 hours since the eruption began.
The lava is gradually approaching a relatively flat area and will presumably begin to slow down and spread out.

The activity on the Northeast Rift Zone continues at intense levels from both eruptive vents.
Fissure 3 continues to effuse the largest and most voluminous lava flows so far, traveling towards the Daniel K. Inouye Highway (Saddle Road) in the north direction. Lava flows decreased its advance between 07:00 AM and 12:30 PM local time today to a rate of 0.02 miles per hour (24 meters per hour). By 12:30 PM local time today, the lava flow front was located about 3.6 miles (5.8 km) from Saddle Road. The lava is gradually reaching a relatively flat area which will likely make it slow down. As this scenario happens, it will spread out and inflate. Preliminary estimates indicate that the lava flows may reach Saddle Road in two days.

Reventador (Ecuador): Mild explosive activity continues from the volcano. The Volcanic Ash Advisory Center (VAAC) Washington reported intermittent emissions of volcanic ash plumes.
The full report is as follows: sporadic emissions of volcanic ash
Sabancaya (Peru): Explosive activity continues. Volcanic Ash Advisory Center (VAAC) Buenos Aires warned about a volcanic ash plume that rose up to estimated 25000 ft (7600 m) altitude or flight level 250 and is moving at 20 kts in NE direction.
The full report is as follows: INTERMITTENT PUFF EMSSION to 25000 ft (7600 m)
Villarrica (Central Chile): The Servicio Nacional de Geología y Minería de Chile (SERNAGEOMIN) reported that the activity at the volcano has been intensifying over the past hours to days.
Weather conditions allowed volcanologists to observe the ongoing behavior today. A strong incandescent associated with vigorous degassing from the summit vent may signalize either elevated fluid movements of gas, water and/or possibly magma under the surface. Glowing emissions of gas and steam rose up to 80-200 meters above the crater.
