Seismic activity at Soputan during the past months (VSI)
In its latest report, VSI describes continuing elevated seismic activity, including shallow volcanic earthquakes and avalanches that indicate slow magma extrusion from the main vent.

Summary of Makian's seismic activity since Jan 2014 (VSI)
Seismic unrest continues at the volcano with a weak tendency of increase in shallow volcanic earthquakes during the past weeks, possibly related to the ascent of a new magmatic body.

Weak explosion at Colima this morning
The activity of the volcano has decreased overall. Explosions have been mostly weak and relatively rare (a few per day) and the previously continuously visible glow at the summit crater, indicative of the small new lava dome, has recently been visible only during increased degassing or explosion events.

Strong explosion at Popocatépetl Tuesday afternoon
No significant changes in activity have occurred at the volcano recently despite a series of stronger explosions during the past days. One explosion on Tuesday afternoon generated an ash plume that rose up to 3.5 km, and another one during the following night was seen ejecting abundant incandescent material outside the summit crater.

Ash plume from a small eruption at Stromboli yesterday (INGV Catania webcam)
The activity at the summit craters has been (comparably very) low recently. However, small strombolian explosions continue to occur at irregular rates of 30-60 minutes intervals, mainly from western vent.

Ash emissions from Etna's NE crater this morning
Intermittent weak to moderate ash emissions (presumably from older pulverized rock) have been occurring from the North-East crater, where also weak incandescence can be seen at night.

Ash plume from Shiveluch volcano last evening
The extrusive-explosive activity of the volcano continues at moderate rate. Glowing avalanches from the active lava dome and strong degassing indicate ongoing magma supply. Occasionally, explosions and larger avalanches that turn into pyroclastic flows occur as well and generate ash plumes that rise several 1000 meters.
