Over the past days, activity at the volcano seems to have picked up. The frequency and size of explosions from the summit have increased and generated several ash plumes that rose up to approx 3 km height above the summit.

In addition, collapses of parts of the lava lobe generated small to moderate pyroclastic flows that traveled up to 3 km down on the ESE side. One of them on Saturday reached again the (already mostly destroyed and abandoned) village of Simacem on the ESE flank at only 3 km distance from the crater.
Whether this apparent increase in activity caused by and actual increase in magma and or gas output, or simply a process of releasing accumulated pressure and instabilities on the already emplaced lava lobes on the steep flanks of the volcano is unclear.
For the local population, this means the long-lasting (more than 2 years now) crisis has no end in sight: the exclusion zone of 4-5 km radius around the volcano (depending on which sector) remains in place. More than 9500 people evacuated from villages in this risk area continue to live in a total of 9 now semi-permanent shelters.

The volcano continues to erupt with little changes overall: the activity consists of slow extrusion of viscous lava, interrupted by intermittent explosions (every few days on average) caused by sudden pressure release of trapped pressurized gasses. An explosion this morning was reported to have produced an ash plume that rose to 14,000 ft (4,2 km) altitude and drifted NW. ... [meer...]

Explosions from the summit crater continue to occur intermittently. An eruption in the evening (18:24 local time) of 12 Feb produced an ash plume that rose approx. 2 km above the summit. [meer...]

Recently, explosions from the active summit lava dome have become more frequent, producing ash plumes that rose 1-2 km above the summit. Extrusion of viscous lava also continues at slow pace, generating small to moderate pyroclastic flows from time to time. [meer...]

A moderately strong explosion occurred earlier today from the volcano, producing an ash plume that rose approx. 2 km. [meer...]

The volcano's eruption continues with little changes into its third year. Slow lava extrusion at the summit results in occasional small to moderate pyroclastic flows as well as sporadic explosions. ... [meer...]
