Sinabung (Sumatra, Indonesia): Sad news today: the volcano claimed its first victims this morning due to a direct effect of the eruption. At least 14 people were reported killed and 3 others severely bunt by one or two moderately large pyroclastic flows this morning. 3 more people are still reported missing.

According to Jakarta Post all fatalities that could be located so far had occurred in Suka Meriah village, which is located within a 3-kilometer radius of the volcano, thus in well in the exclusion zone. However, during the past days, enforcement of the exclusion zone had been loosened, and according to some sources, people had even be formally allowed to return to their homes,- a fatal decision for some.

Kavachi (Solomon Islands): (1 Feb) A submarine eruption is likely occurring at the submerged volcano. A NASA satellite image from 29 Jan shows a plume of discolored sea water swirling and drifting from the location of the volcano. The discoloration is likely from suspended volcanic sediments (the fragmented lava) and gasses.
Kavachi is an undersea volcano on the southern edge of the Solomon Islands in the western Pacific Ocean. It erupted dozens of times in the 20th century, often breaking the water surface, only to be eroded back below the water line within a few months.
Whether the new eruption will break the surface and create another new island remains to be seen. Directly above the undersea peak, a bright patch is visible that suggests vigorously churning water—but there is no sign that the eruption has broken the surface. (NASA)
Tungurahua (Ecuador): Activity continues at the volcano. Several relatively strong ash emissions occurred during the past 12 hours, producing ash plumes rising 2-3 km above the volcano to estimated 26,000 ft (8 km) altitude and drifting SE:
The volcano observatory reports frequent small explosions and visible incandescent material.

Sinabung (Sumatra, Indonesia): The eruption shows little variations as the volcano continues to effuse viscous magma at the summit vent. A part of that simply contributes to the growth of the lava dome and the viscous lava tongue that descends on the SE flank. Another part of the new magma collapses and produces rock-falls that turn into pyroclastic flows such as this morning (video): ... read all

Etna (Sicily, Italy): The recent eruptive episode, which could be called a mainly effusive paroxysm, seem to have more or less ended. Activity if still present (weak explosions at the NSEC and lava effusion from the fissure vent at its base) has decreased a lot. Visibility and weather are bad at the moment to have a more detailed picture. ... read all
