Etna (Sicily, Italy): This morning at 12:08 (local time) a moderate phreatic explosion occurred from the Bocca Nuova crater.

Kelud (East Java): Additional details and new estimates about the recent explosion are emerging. Unfortunately, a 4th fatality caused by the eruption has now been confirmed by BNPB. All victims were within 7 km of the volcano. More than 100,000 people have been evacuated.
Fast rise of magma?

Ash from the eruption is still drifting over the eastern Indian Ocean. More than 100,000 people have reportedly evacuated areas close to the volcano. Heavy ash fall occurred in vast areas of Java. A preliminary judgement of the erupted ash suggests that the explosion was a magmatic event, i.e. triggered by a new bash of fresh magma that seems to have risen very quickly to the surface:
Our correspondent Andi wrote: "Jogja and many cities in the west and east of Java is covered by raining ash and layered until 3-4 mm. It's terrible that the ash could reach Jogja and other cities until 500 km away from Kelud as well as covered Borobudur temple again as in eruption 2010. ... The color (of the ash, rmk) is white powder and some black particles inside as well that maybe there is some pyroxene (small black particles)."
Sinabung (Sumatra, Indonesia): The eruption continues with no significant changes, but on a progressively decreasing trend. Most activity has been the slow extrusion and gradual enlargement of the lava dome-lobe oozing out from the vent and onto the southern slope. Occasional rockfalls and minor pyroclastic flows occur as well.
As the intensity of the eruption decreases, refugees have been returning to their homes (except those from the closest villages at only 3 km distance).
A recent analysis of the erupted lava confirmed that the currently erupted lava is andesite (a viscous type of magma with intermediate silica content, and typical for volcanoes in subduction settings such as Sinabung and most other volcanoes in Indonesia).
Kilauea (Hawai'i): (14 Feb) Per HVO, Kilauea's summit lava lake continues to rise. Measured at 35m/115ft below the floor of Halema'uma'u. Pictured here, the lava spills slightly over inside the crater onto it's shelf earlier this morning.

Kelud (East Java): BNPB (Civil protection) confirmed 3 fatalities (indirectly or directly) caused by the eruption: two as result of breathing difficulties caused by the ash, one as a road accident during evacuation. All of the victims were in Pandasari village less than 7 km from the volcano where 20 cm of ash has fallen. ... [more]
