Bezymianny (Central Kamchatka Depression): (30 Jul) Last night, Tokyo VAAC reported an ash plume from the volcano at 20:40 UTC, based on satellite data. ...more
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.

The paroxysm at Fuego, which had reached its peak phase during the night of Thu-Fri (28-29 July) has ended. Starting from the early afternoon yesterday (local time), activity gradually decreased and the volcano's activity has by now returned to intermittent smaller strombolian explosions. ...more
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.

Signs that a new eruption of the volcano in the near future could be in the making have been increasing. In a bulletin yesterday, the volcano observatory (OVPF) reported elevated seismic activity, deformation and gas emissions that are consistent with the rise of magma to shallow depths. ...more
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). [less]

As of yesterday evening (morning in Hawai'i), the new sea entry of the "61G" lava flow near the Kamokuna area continued to be active with and was at least 20 meters wide, spilling over the older sea cliff. ...more
It can be expected that the sea entry will widen over time. Another lobe of the main flow has been advancing along the west margin and might hit the ocean soon as well.
At the summit and Pu'u 'O'o crater on the eastern rift zone, no significant changes have occurred. Halema'uma'u lava lake has risen a bit again to approx. 23 m below the crater floor rim and the lava pond inside Pu'u 'O'o is active as well.

Another intense eruptive phase with strong explosions, lava fountaining and abundant lava flow activity is in progress at the volcano. ...more
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. [less]

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]

Chikurachki (Paramushir Island): A new eruption was reported by Tokyo VAAC who discovered new ash emissions from the volcano since yesterday morning. The ash plume observed on Himawari 8 satellite imagery rose to estimated 18,000 ft (5.4 km) altitude and drifted over 150 km to the NE passing the southern part of the Kamchatka peninsula. ...more
Based on satellite imagery, it seems that the eruption started as a violent explosive event yesterday at 03:20 UTC (14:20 afternoon local time). The ash plume reached Kamchatka's southern tip 3 hours later, spreading at an average of approx. 30 knots.
Chikurachki, one of the many active and rarely directly observed volcanoes in the Kurile Arc, has often produced short-lived, but sudden and very violent explosive eruptions in the past years. [less]

The volcano remains calm at the surface but is restless. Its internal seismic activity continues to be higher than normal and SO2 gas emissions have increased a bit recently (to approx. 7,000 tons/day), which could indicate the influx of fresh magma. ...more
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.

Kilauea (Hawai'i): The so-called "61G lava flow" southeast from Pu'u 'O'o extending into the coastal flat remains active, but most activity in the past days continued to enlarge and inflate the existing lava flow field. ...more
The most advanced flow front, located 820 m from the coast, was stalled when observed this morning, but there were active breakouts a few hundred meters further inland. A new surge of advance can occur any time.

Sinabung (Sumatra, Indonesia): No significant changes have occurred in the ongoing effusive-explosive eruption of the volcano. The slow lava dome growth continues to feed a prominent lava lobe on the upper ESE flank that sheds glowing avalanches. ...more
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. [less]

The latest mapping of the active lava flow in the coastal plain shows that the leading tip was about 870 m from the coast yesterday. Most of the activity in recent days has been the overriding and widening of the lava flow field, with only little net advance of the farthest lava front towards ocean. ...more
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. ...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]

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.

Activity of the volcano has remained more or less unchanged during the past weeks. The western crater continues to produce intermittent (every few days) episodes of continuous, but relatively mild ash emissions. Not all of them can be observed due to cloud cover, but show up from the accompanying volcanic tremor. ...more
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.

The activity at the volcano remains essentially unchanged and CENAPRED maintains alert level "Yellow Phase 2". As magma continues to slowly rise inside the conduit, it accumulates in the inner summit crater as a flat pancake-shaped dome and causes small to moderate intermittent explosions with more or less ash. ...more
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. [less]

The active lava flows in the coastal plain are now only about 1 km from the coast. Their advance has slowed down significantly as the lava is now in almost flat terrain and the arriving new lava is mostly "used" to inflate the fresh field and expand its sides, until a main lava tube is established in the coastal flat as well. ...more
It is impossible to predict when lava will be hitting the ocean- this could be within few days or even less or still take weeks (if at all, but it is now extremely likely).
The volcano's summit is currently undergoing a period of deflation and the lava lake in Halema'uma'u has dropped a bit; yesterday morning, it was 35 meters (115 feet) below the floor of Halema`uma`u crater. [less]

The volcano remains highly restless, the hydrothermal system probably being disturbed by a shallow magma body. ...more
A sudden and quite violent phreatic explosion, result of overheated ground water flashing to steam, occurred last Tuesday, ejecting mud and water to 200 m above the crater lake.

Kliuchevskoi (Kamchatka): The effusive-explosive eruption of the volcano continues. The active lava flow on the eastern slope remains well alimented and ash emissions from intense strombolian activity at the summit often generate smaller and moderately sized ash plumes that reach several hundred meters of height above the crater. ...more
During end of June, a series of collapses occurred from the lava flow on the eastern slope, generating small glowing avalanches.
The rhythmic explosive activity at the summit crater also generates occasional "smoke rings" (or better: gas rings, ring vortexes created by rapid degassing through circular vents) such as the one shown in the second picture attached. [less]

The activity at the volcano has again picked up. An intense thermal anomaly is visible on recent satellite data and is stronger than during the preceding eruptive phase in March-May this year. ...more
A (rare) aerial image taken on 28 April shows the volcano's summit occupied by fresh lava, a new cinder cone and a breach in the southwestern crater wall with a lava flow tongue present on its slope beneath (visible by the steaming front).
The current thermal anomaly is almost certainly due to another phase of intense lava effusion, likely in the same location (although recent photographs would be need to confirm this). [less]

The new lava flow southeast of Puʻu ʻŌʻō continued to be active and made some rapid advance through the coastal plain: when HVO last mapped it Tuesday afternoon, the nearest lava front was only about 1.7 km (1.1 miles) away from the coast, after having advanced nearly 1 km alone since the morning of Monday (i.e. little more than 24 hours). ...more
If the current rapid advance continues, lava might begin to flow into the ocean - and construct new land on Hawai'i - very soon (few days?). [less]

Guessing game - when will the lava reach the sea?
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...).

The new spatter cone in strombolian activity inside Copahue's intra-crater cinder cone on 3 July 2016 (SERNAGEOMIN)
The vent, approx. 1-2 meters wide, is located inside the crater of the cinder cone which itself been growing during the (mainly phreatic and phreatomagmatic activity) over the past two years, partially filling the Al Agrio crater.
The onset of this strombolian activity with magma arriving directly to the surface likely was towards mid or end of June, when an increase in internal activity (seismicity) was seen on instruments and glow from the volcano became more intense at night. [less]
