Etna (Sicily, Italy): The volcano remains highly restless. Although no more lava is being erupted right now, strong gas and dense ash emissions continue from the Bocca Nuova crater as a sign that magma is close to the surface.
Seismic activity as well remains elevated. Today, a cluster of small earthquakes occurred at shallow depths (1-8 km) beneath the SW flank, which could indicate another intrusion beneath that area. The largest was a magnitude 3.4 event at 19:30 local time, felt by some residents nearby.
Shiveluch (Kamchatka): The eruptive activity of the volcano continues; glow is visible on the webcam and suggests that indeed lava dome growth has resumed.
Satellite data show the ash plume from this morning's larger eruption is still at 5-6 km altitude a.s.l. continues to drift for about 245 km to the south-west and later west from the volcano.

Volcanic Ash Advisory Center Tokyo (VAAC) issued the following report: VA EMISSIONS CONTINUING OBS VA DTG:30/0820Z
A powerful, brief explosion has sent ash possibly up to 40,000ft (12km), prompting KVERT to raise the Aviation Colour Code to Red. Activity has recently returned to a moderate level following a hiatus for most of the year. Explosions like this are typical for Sheveluch- many have happened in the past 25 years as dome-building continues.

Dukono (Halmahera): (30 Dec) Volcanic Ash Advisory Center Darwin (VAAC) issued the following report: CONTINUOUS VA TO FL070 MOV ESE 20KTS OBS VA DTG:30/0450Z
Agung (Bali): The volcano erupted again early this morning (30 Dec 2018) at 04:09 local time. A moderately sized sudden explosion lasted for 3 minutes 8 seconds, caused by accumulated overpressure of gasses inside and under the lava plug that had formed on top of the conduit by the magma erupted in the 2017-18 eruption.
The Indonesian Volcanological Survey reported that "fire" (i.e. incandescence) was observed in the summit area of the crater, but the height of the ash column was not observed due to fog. Based on satellite data, a plume rose to approx. 18,000 ft (5.5 km) and drifted southeast. Light ash fall was noticed in the Karangasem Regency in the southeast sector of Mount Agung, such as in Amlapura City and several other villages such as Seraya Barat, Seraya Tengah, and Tenggalinggah Village.

Volcanic Ash Advisory Center Darwin (VAAC) issued the following report: VA TO FL180 MOV SE OBS VA DTG:29/2110Z
Krakatau (Sunda Strait, Indonesia): On 17 Oct, explosions were particularly violent at Anak Krakatau. We show a series of images of a spectacular explosion captured from close range by boat. 2 months later, the cone of Anak Krakatau collapsed into the sea on the evening of 22 Dec 2018, triggering a catastrophic tsunami (more info).
Continued activity that accumulated more and more weight on the cone, built on top of a steep underwater slope in the SW (left in the images), and shaking by explosions like this might well have been the final trigger for that tragic event.

Etna (Sicily, Italy): The decreasing trend in surface and earthquake activity on and around Etna continues and there is little to nothing left of the vigorous flank eruption that had started on Christmas Eve (24 Dec 2018). However, the volcano is far from quiet and there are indications that more and potentially more dangerous activity could be in the making. ... [more]
