Map of today's active volcanoes
While it is entirely possible that activity at the lava dome of Bezymianny has picked up or that a collapse occurred which generated an ash plume, it could also be an ash plume from nearby Klyuchevskoy volcano (image).
At the moment, the latter possibility seems more likely. Cloud cover prevented direct observation to confirm whether or not there is new activity at Bezymianny. KVERT has not issued an alert about the latter.

Ash plume from Fuego yesterday morning with lava fountains
The lava effusion dropped as well. As of yesterday evening, the two lava flows on the SE side were still active and 1500 m long while explosions at the vent were still reaching 400 meters height; by this morning, the lava flows continued to be active, but had decreased to a few hundred of meters length and are probably going to stop soon.

Number of earthquakes under Piton de la Fournaise volcano over the past weeks(OVPF)
The recent seismic unrest began on 13 July; since then, OVPF recorded 163 shallow volcano-tectonic earthquakes (at depths within 2 km below the summit), including two swarms on 19 and 26 July, as well as 226 small collapses and rockfalls in the Dolomieu Crater.
Also since 13 July ground inflation at Dolomieu crater (swelling of the edifice caused by magma intrusion) picked up significantly. It currently continues at rates similar to those recorded before the recent eruptions of 2015 and 2016 (rates around 1 mm distance gain / day).

Lava fountaining from Fuego volcano this morning
After increasing gradually over the past week, the new so-called paroxysm (the 12th such phase in 2016 according to INSIVUMEH) started yesterday morning and seems now to be at its peak. Strombolian-type explosions and/or pulsating lava fountains eject glowing lava to 400 m or more, generating abundant glowing avalanches on the upper cone, and are accompanied by shock waves that can be felt in up to 15 km distance.
Two lava flows of each about 2000 m length are descending the Las Lajas and Santa Teresa gullies on the southeastern flank.

Most likely, the summit crater vent is currently producing strombolian-type activity, possibly along with the effusion of lava flows. Seismic activity has been elevated.
According to the Alaska Volcano Observatory (AVO), "vigorous steam degassing was observed in web camera images from Cold Bay (35 miles or 60 km SW) and Black Hills (20 miles or 35 km NNE) this morning. Satellite observations and pilot reports indicate minor amounts of ash associated with the steam cloud at an altitude of less than 15,000 ft (4.5 km) above sea level." [less]

Eruption of Turrialba this morning (image: RSN)
Costa Rican volcanologist describe the explosions which each lasted a few minutes as phreatic, i.e. driven by overheated water from the hydrothermal system suddenly flashing into steam. The first explosions occurred at 21:22 and 22:16 local time last night and were followed by similar ones at 07:22 and 08:25 this morning.
The eruptions were similar to many others in the ongoing phase of intermittent explosions at the volcano during the past months; they ejected ballistic blocks of high temperature to the crater rim and generated ash plumes that rose several hundreds of meters before drifting SW where ash fall occurred in nearby areas.

According to HVO's latest update, earthquakes at Mauna Loa during the past week "occurred beneath the west and north flanks of the volcano mostly in the 5 – 11 km (3 – 7 miles) depth range. In addition, earthquakes are occurring in south caldera and upper Southwest Rift Zone at depths less than 5 km (3 mi).
Global Positioning System (GPS) measurements show deformation related to inflation of a magma reservoir beneath the summit and upper Southwest Rift Zone, with inflation occurring mainly in the southwestern part of the magma storage complex."

Additionally, occasional small ash puffs, along with pulsating gas emissions, have been observed at the New SE crater since 10 July. These are likely signs of deep-seated explosive activity (degassing from the magma column inside the conduit). Volcanic tremor remains currently stable with no clear trend, but this can change quickly.

Occasional larger collapses of this lava lobe produce more violent pyroclastic flows.
In addition, the volcano continues to produce explosions, caused by trapped, pressurized gasses contained in the magma from the upper conduit or the dome itself. These vertical explosions have been occurring at rates of one per day on average recently. This morning, an ash plume rose to 15,000 ft (4.5 km) altitude, i.e. approx. 2 km above the summit.

However, if the feeding of fresh lava through the main tube into the lava field in the coastal plain continues, and eventually establishes itself over increasing distance, it is more and more likely that the lava eventually reaches the sea. This is likely to occur in the near or medium-term future (days to weeks). [less]

The volcano is showing signs of unrest that could be (but not necessarily) precursors of a new eruption. Since the beginning of the month, shallow (0-2 km depth) volcanic earthquakes of rock-fracturing type under the Dolomieu crater (the main vent of the volcano) have been more frequent, probably caused by a new magma intrusion. Read more...The volcano observatory's (OVPF) latest statement mentions that 111 "collapses" have occurred recently on the Dolomieu crater, the Enclos and on the lava flow of Aug-Oct 2015.
In addition, it seems that new deformation has started during the past days, which would fit into the picture that the volcano is likely preparing itself for a new eruption, although the trend was still unclear and needs to be confirmed. [less]

Shiveluch (Kamchatka): The volcano's activity has been comparably low recently, but continues as viscous lava rises and accumulates at the active lava dome. A small collapse occurred yesterday evening, triggering a pyroclastic flow on the SW flank of the dome and producing an ash plume that rose to approx. 3.5 km above sea level.

Map of today's active volcanoes
A recent satellite image allows to determine that fresh lava flows have erupted (or still are erupting) from the summit vent(s) and accumulate in the northern part of the summit caldera.
Judging from the attached high-resolution satellite image, it seems likely that the main vent, a cinder cone that has been forming since the start of the recent eruption last October, remains active, likely with strombolian activity, while the lava flows themselves originate from two (?) flank vents at its northern feet.

Ash emissions from Turrialba on 9 July 2016 (RSN)
This activity is probably mainly phreatic in nature, as the volcano's currently unstable shallow hydrothermal system interacts with an underlying small magma body.
Recent ash samples were found to contain about 10% juvenile material which originates from the new magma. Whether the amount of magma participating in the surface activity increases (towards a more magma-driven eruption) or decreases (ceases) in the near to medium future, i.e. how the eruption evolves, will depend on ho the volume of magma involved and may other factors (gas content, internal pressure etc) and cannot be predicted at the moment.

Ash emissions from Popocatépetl Sunday morning (Webcams de Mexico webcam)
This activity is not completely stable, of course, but shows sometimes significant variations: a marked increase of seismic activity occurred during the past days, including a swarm of volcano-tectonic earthquakes and prolonged phases of tremor, probably related to the rise of new magma into the volcano's plumbing system. At the surface, more vigorous ash emissions and more intense glow at the summit were seen and occasionally, stronger explosions were able to throw incandescent bombs outside the crater. The activity has declined again since yesterday.

If the recent average speed of advance of approx 140 m per day continues, lava could reach the Pacific in approx. 3 weeks, although it is likely that the advance of the front slows down with distance on flatter ground and it might then take a little longer (although the opposite can become true as well...).

Hawai'i and Kilauea volcano photos: Lava flows, lava lakes, eruptions and aerial images from Kilauea on the Big Island of Hawai'i throughout the years.
Latest quakes at Katla volcano: One of Iceland's most active and dangerous volcanoes is showing signs of unrest and statistically due for a new eruption. Earthquakes could give a clue.
Convergent plate boundaries and subduction zones: As an oceanic plates collides with another plate, it is subducted and generates volcanism on the overlying plate.
Latest quakes in Greece: Greece has a lot of earthquake activity, but most of them occur around the margin of the Aegean microplate. The Cycladic islands are located in its center and therefore seismically comparably quiet.
