Manam (Papua New Guinea): A volcanic ash plume at estimated 7,000 ft (2.1 km) altitude extending 70 km north from the volcano was reported this morning (VAAC Darwin).

Karangetang (Siau Island, Sangihe Islands, Indonesia): The eruption continues at the volcano: it is characterized by Strombolian activity at the summit crater and lava extrusion that forms frequent incandescent avalanches.
Devy Kamil Syahbana posted images of this activity during the last week.

Dukono (Halmahera): Continuous ash emissions are being observed from the volcano, generating plumes at 2-3 km altitude that drift up to 70-80 km to the east (Darwin VAAC).

Lokon-Empung (North Sulawesi, Indonesia): A small eruption occurred again last Saturday, producing an ash plume that rose approx. 2 km and drifted northeast, caused a temporary closure of the Manado airport.
The explosion occurred around 23:50 local time a vent in or or near Tompaluan crater. The volcano remains at alert level 3 ("siaga") on a scale of 1-4 and a safety zone of 2.5 km around the crater is recommended as similar, sudden explosions are likely to occur again from time to time.

Kilauea (Hawai'i): No significant changes have occurred at the ongoing eruptino on both the summit vent (Halema'uma'u lava lake) and the east rift zone. During the past days, lava flows have resurfaced most of the interior of what is left of Pu'u 'O'o crater.
The lava lake at Kīlauea's summit remains active, and periodically rises and falls along with cycles of inflation and deflation. At the moment, summit tiltmeters have been recording deflation.
The new East Rift Zone lava flow northeast of Puʻu ʻŌʻō remains active within 8 km (5 mi) of the vent. The flow does not currently pose a threat to communities. Low levels of seismic activity continue across the volcano (HVO).

Colima (Western Mexico): Explosions continue to occur from time to time at the volcano. During an overflight on 25 August, researchers from the University of Colima found that as a result of the explosions, the crater had been deepened by 20 meters during the past 2 weeks and is now approx. 60 m deep and 270 m wide, similar to what it was after the large eruption in 1913.
According to the scientists, the volcano's activity is currently in a decreasing trend, which corresponds to the decreasing size and frequency of explosions recently.

Nevado del Ruiz (Colombia): A phase of ash emissions occurred early today at the volcano. A strong pulse of volcanic tremor started at 03:21 local time.
Light ash fall was later detected in different parts of Manizales. In the early morning, a steam plume was seen rising approx. 400 m from the volcano.

Cotopaxi (Ecuador): Activity at the volcano remains high while seismic activity has been showing a decreasing trend today and been described as moderate by the Geophysical Institute.
During last night and this morning, ash and steam emissions continued, producing a plume that drifted WNW.
Weak ashfall occurred in central Machachi and in the El Chaupi, Pichincha, as well as in parts of the canton Rumiñahui.

Michael (United Kingdom, South Sandwich Is): One of the remotest active volcanoes is in eruption again. In a satellite image from 26 August 2015 obtained from the NASA's Earth Explorer program, the east flank of Mount Michael volcano can be seen stained grey which strongly indicates that an eruption took place.
