Strombolian eruption from Raung volcano
Pyroclastic flow from Colima this afternoon
Raung (East Java)
Degassing from Sabancaya volcano last week (IGP)
: The eruption inside the summit caldera continues with intense strombolian activity and the effusion of an intra-crater lava flow.
Ash emissions have been intense enough to produce a plume that rose to 17,000 ft (5 km) altitude and drifted more than 150 km to the SE. Several regional airports including Denpasar (DPS) on Bali have been closed.
A recent visit by our friend and volcano expedition organizer Aris Yanto / Exploredesa shows that a new cone has been built inside the crater.Sinabung (Sumatra, Indonesia)
: Activity at the volcano has been comparably low. On average, 2-3 smaller pyroclastic flows per day have been occurring, our expedition leader Andi who is currently at Sinabung reported.Sangeang Api (Indonesia)
: The volcano continues to erupt. On Wednesday (8 July), an explosion generated an ash plume that rose to 9,000 ft (2.7 km) altitude and drifted 35 km to the south.
When flying past the volcano during our recent Batu Tara expedition
, we could see a dense gas plume drifting from its summit crater.Sirung (Pantar Island, Indonesia )
: Darwin VAAC raised the aviation alert level to orange, after a plume of steam and possible light ash emissions were seen on satellite images drifting SW from the volcano last Tuesday.
Local observers reported a thick steam plume rising approx. 500 m from the volcano, but the volcano observatory had no particular indications (such as increased earthquakes, sulfur smell, rumblings) of a new eruptive phase.
The last confirmed activity at the volcano was likely a (single) phreatic explosion in May 2012.Dukono (Halmahera)
: The volcano continues to erupt dense, but low level ash plumes that often can be detected on satellite imagery drifting 30-50 km NE.Colima (Western Mexico)
: A new eruptive phase has started at the volcano earlier this month. A new lava dome started to grow quickly in the summit crater and has been producing frequent explosions, glowing avalanches and pyroclastic flows (video):Sabancaya (Peru)
: Since mid June, an increase in internal activity has been recorded at the volcano. The Geophysical Institute of Peru reported a swarm of shallow earthquakes in an area at 6 km depth approx. 7 km north of the volcano's summit. In addition, increased degassing has been observed. Both are likely signs of a probable magmatic intrusion.
During the first week of July, activity decreased a bit, but remained significant. IGP does not expect a large scale eruption in the near future, but warns that sudden explosions could occur at the crater.
Long-period seismicity (fluid movements) decreased to averaged of 72 events / day, while shallow rock-fracturing quakes remained frequent with an average of 9 per day.
