Map of today's active volcanoes
Glow from Klyuchevskoy's lava flow this evening

MODIS thermal signal from Fuego volcano (MIROVA)
Klyuchevskoy (Kamchatka): The effusive and sometimes mildly explosive eruption of the volcano continues with little changes.
Ash plume from an explosion at Fuego this morning
Bright glow at night and strong thermal signals detected on satellite show that the lava flow through the Apakhonchich drainage on the SE flank of the volcano continues to be well fed.
Suwanose-jima (Ryukyu Islands): After about a week of relative calm, the volcano's activity - probably strombolian explosions from Ontake crater - has again picked since last night.
Bright glow is visible at the main crater from neighboring islands and Tokyo VAAC reported several low-level ash plumes today.
Batu Tara (Sunda Islands, Indonesia): The volcano's activity seems to have been very low recently although there are no available direct observations.
The heat signal from the volcano has been only intermittent and low and no significant ash emissions have been detected on satellite imagery during the past months (since about Dec 2015). Only a gas plume is visible on clear weather satellite imagery on most days.

Sinabung (Sumatra, Indonesia): The volcano has been producing a series of glowing avalanches and pyroclastic flows on the ESE and SE sides during the past 24 hours, reaching lengths of 1500-3500 m.
The cause of the current violent phase is likely that the prominent viscous lava lobe that has been spilling over from the summit dome into a steep ravine of the upper flank has now become too unstable and is crumbling apart.

Fuego (Guatemala): The activity at the volcano has again started to increase - while it continues with intermittent explosions, satellite-based measured heat emission from the summit is becoming more intense, typically a sign that the magma column is rising inside the conduit.
This could herald a new paroxysm in the near future (coming few days?).
Volcanic Ash Advisory Center Washington (VAAC) issued the following report: VA EMS OBS AT 1230Z
Cotopaxi (Ecuador): Yesterday's ash plume from the volcano was the result of strong winds remobilizing older ash deposits (from the recent eruptive activity during 2015-16), NOT cause by a new eruptive phase.
The volcano is currently calm both at the surface and internally (seismic activity, deformation etc) and only emits a steam plume.
