Shiveluch (Kamchatka): KVERT reported that during 8-15 May lava-dome extrusion onto Sheveluch’s N flank was accompanied by incandescence, hot block avalanches, and fumarolic activity.
A daily thermal anomaly was also detected in satellite images. The Aviation Color Code remained at Orange.
(Smithsonian / USGS Weekly Volcanic Activity Report 13-19 May 2015)

Sinabung (Sumatra, Indonesia): The eruption continues with no significant changes. Viscous magma effuses slowly from the summit vent and continues to grow a new lava lobe on the upper southern flank.
Collapses of parts of this unstable lava mass generate small to moderate pyroclastic flows.

Ambrym (Vanuatu): Activity at the volcano remains elevated. Lava lakes are active in Bembow and Marum craters. Geohazards maintains volcanic Alert Level 2:
"The danger remains in the caldera area around the volcanic craters of Benbow and Marum (including Maben-Mbwelesu, Niri-Mbwelesu and Mbwelesu) and on volcanic ash and gas prone areas exposed to trade winds."

Colima (Western Mexico): Explosions continue to occur from time to time. On 16 May an ash plume rose from Colima to an altitude of 5.5 km (18,000 ft) a.s.l. and drifted 95 km ESE before dissipating.
A new lava dome might have started to grow inside the summit crater, where a flat, elevated ash-covered area is visible on a recent aerial photo.

Nevado del Ruiz (Colombia): Mild ash emissions continue to occur irregularly from the volcano, producing plumes of a few hundred meters height. More intense activity yesterday prompted authorities to close the Manizales regional airport "La Nubia" until 31 May.

Cerro Negro de Mayasquer (Colombia): Seismic activity at the volcano has been decreasing during the past months. No other signs of volcanic unrest have been detected.

Reventador (Ecuador): Activity at the volcano remains at moderate to high levels, according to IGPEN. The lava flow that started on the southern flank on 19 May has not advanced any more during the past days and might be cooling. In turn, explosions have picked up a bit from the summit vent.

Ubinas (Peru): Activity remains low at the volcano. No explosions have occurred recently, only mild to moderate steam emissions, sometimes mixed with light ash, reaching up to 1-1.2 km height and drifting mainly east and northeast.
On the other hand, SO2 emissions were elevated and seismic activity, in particular rock-fracturing earthquakes, picked up a bit during the past week. This suggests that the internal pressure has increased compared to earlier this month.
