Fogo (Cape Verde): It seems that eruptive activity which had started on 23 Nov last year has finally stopped on 7 February, according to a post by Asociación Canaria de Volcanología on facebook.

It may be a bit too early to be sure to declare the eruption ended, because pauses in eruptive activity are not uncommon. On the other hand, activity had been showing a decreasing trend over the past weeks, and it would be no surprises if it actually did end now.
Sinabung (Sumatra, Indonesia): Another large pyroclastic flow occurred yesterday morning. The flow traveled 2-3 km to the base of the mountain and produced an impressive coignimbrite ash plume that rose to approx. 4 km altitude.
The volcano's eruption continues mostly quietly to effuse viscous lava, feeding a flow emplaced on the upper southeastern flank. At times, such as yesterday, it becomes too unstable and smaller or larger parts of it can collapse, generating dangerous pyroclastic flows.
Colima (Western Mexico): A small vulcanian-type explosion this morning produced a beautiful, vertical ash column rising approx. 2 km (no wind).
Fuego (Guatemala): The recent, strong paroxysm ended Sunday. It had lasted 22 hours. CONRED reported that the volcano now returned to its typical intermittent strombolian activity with weak to moderate explosions.
The lava flow towards the Trinidad and Ceniza canyon on its upper flank remains weakly active, although seems to be decreasing.
Guatemala's international airport has resumed operations.

sent us this great photo from the first evening of the eruption, showing the typical alignment of active vents along the eruptive fissure.

The eruption continues without major changes. The volcano observatory OVPF reports low, but stable tremor levels. Webcam imagery from last night (before clouds obscure views) show that the eruption is mainly effusive with only weak explosive activity (weak spattering) at the vents.
Currently, a small lava flow is active that extends approx 500 m from the base of the Dolomieu cone, enlarging the new lava field of partially overlapping flows at its base. The middle section of the lava flow is through a lava tube, making it invisible in this part on the webcam images.
