Manam (Papua New Guinea)
Active lava flow on Reventador today, seen on the thermal webcam
: According to Darwin VAAC, an ash plume from the volcano rose 8,000 ft and extended 70 km to the NE today. The volcano seems to be in a phase of intermittent mild explosive activity.
Raung (East Java)
: Eruptive activity continues in the volcano's summit crater. Heat emission remains intense, suggesting the presence of lava (flow?), likely in combination with more or less intense strombolian activity.
An ash plume was seen on satellite data last Friday. (VAAC Darwin)
Sinabung (Sumatra, Indonesia)
: Activity remains intense. The volcano continues to extrude viscous lava that regularly generates glowing avalanches and pyroclastic flows. Associated ash plumes have been rising several kilometers. The volcano remains at highest alert level (4 out of 4).
Sangeang Api (Indonesia)
: Satellite data suggest that a new lava flow is active traveling from the summit crater of Doro Api through a narrow ravine on the SE side of the volcano.
It is possible that effusive activity which began in early June last year in reality never ceased, but increased again now. The volcano began erupting with a large explosion on 30 May and several smaller ones in early June last year. This was followed by the effusion of a flow that quickly traveled down the SE slope of the volcano. Thermal signals remained intense until November 2014, then decreased, but did not disappear, but clearly picked up again late April this year, indicating the presence of active lava always in the same path.
The current length of the flow is probably around 1.5 km.
: Ash emissions at variying intensity continue from the volcano. Darwin VAAC reported ah ash plume that rose to 6,000 ft (1.8 km) and extended 50 km NE yesterday.
Wolf (Galápagos Islands, Ecuador)
: The eruption in the Galapagos islands continues strongly from the effusive vent inside the caldera, near its southern rim.
A detailed report
by the Ecuadorian Geophysical Institute confirms that the current intra-caldera activity must have started between including 13-16 June, likely from a new fissure vent near or on the southern caldera rim. Lava flows from this vent have been covering the 1982 lavas in the the S and SE part of the caldera floor.
The lava flows from the first phase of the eruption, emitted by an eruptive fissure that ran parallel and just outside the SE and E caldera rim, seem to have stopped being alimented at around the same time the new actity began inside the caldera.
: Activity at the volcano has been relatively intense during the past days with at least one active lava flow, approx. 1-1.5 km long, traveling down the SE side of the summit cone.
After the previous flow from 19 May had stopped, probably in early-mid June, a new surge started on 23 June and is still continuing.
: Intermittent explosive eruptions continue. An explosion on Friday 26 June at 14:58 local time produced an plume that rose 2.8 km and caused light ash fall in nearby areas a local newspaper reported.
Another smaller explosion was reported yesterday evening (VAAC Washington).
