Etna (Sicily, Italy): The 21st paroxysm at the New SE crater which started last evening is still going on although it has decreased a bit. Until now, the eruption has been rather weak with no sustained tall lava fountains as during most of the paroxysms. Instead, the New SE crater continues to produce loud, spectacular near-continuous strombolian-type jets (or low, pulsating fountains) and explosions of lava bubbles. The eruption so far:

...29 Dec:
The 21st paroxysm at the New SE crater is in progress, but has still to reach its climax. At the moment, violent continuous strombolian explosions or low pulsating lava fountains occur at the summit vent and a lava flow has started to issue from the fissure vent on the SE flank of the cone.

El Hierro (Canary Islands, Spain): No new earthquakes have occurred, but deformation continues and shows that the current crisis is not yet over.
A new pattern is slowly emerging: while the SE areas that experienced rapid uplift (presumably by magma accumulating beneath the crust in that area) are stagnating or even showing slight subsidence (El Pinar), the northern and western areas, in particular the western El Golfo depression have started to experience uplift. The strongest deformation occurred in Sabinosa (GPS station HI03) with ground uplift of almost 3 cm during the past 24 hours. Weak tremor continues also to be present on seismic signals from this area.

Sinabung (Sumatra, Indonesia): The growing lava dome has started to produce (extremely dangerous) pyroclastic flows, as parts of the unstable mass of the viscous lava have now overtopped the crater the dome had been growing inside.
The first series of 3 flows apparently took place this morning at dawn on the southeast slope and reached up to 1.5 km length. More pyroclastic flows occurred at 17:22 and 18:36 local time, reaching maximum run-out lengths of approx. 2.5 km.
Valleys radiating from the volcano should be avoided at all times in distances up to many kilometers. During Merapi's deadly eruption in 2010, some flows reached lengths of over 20 km.

San Miguel (El Salvador): (29 Dec) A new eruption began at the volcano this morning at 10:50 am local time. A strong vulcanian-type explosion produced an ash plume of unknown but considerable (several km) height.
According to local press, ash fall was expected in the town of Chinameca and Civil Protection has begun evacuations of families residing in a radius of 3 km around the volcano.
