Bardarbunga (Iceland): The eruption continues with little variations. We flew over the fissure and could observe lava fountains still going strong from the main vents on the active fissure.
IMO reported that the lava erupted seems to be slightly less than the lava intruded at depth, as slight ongoing deformation revealed by GPS suggests.
The short answer is that most likely, the gasses released by this eruption will not present a big threat except in near downwind areas of the eruption.
For a more in-depth discussion of this topic, please have a look at this post on all-geo.org.
No changes have occurred. The eruption continues at similar levels as during the past days. The flows are now more than 16 km long.
NASA Earth Observatory published satellite images showing the extent of the flows on 6 Sep:
Nishino-shima (Volcano Islands, Japan): Lava flows continue to be active and enlarge the growing island. During the past weeks, these have contributed to the growth of a platform towards the north of the active vents.
Rabaul (Tavurvur) (New Britain, Papua New Guinea): Intermittent strombolian to vulcanian-type explosions continue at the Tavurvur volcano. VAAC Darwin reported an ash plume rising to 10,000 ft / 3 km altitude this morning.
Semeru (East Java, Indonesia): The slow extrusion of a lava flow from the summit crater continues and forms a dark tongue extending a few 100 meters. Rockfalls detaching from it roll frequently down the Kembar ravine on the southern flank.
On contrast, the previously typical intermittent strombolian ash explosions of the volcano, in continuous activity since 1976, have been almost absent during the past months.
Kilauea (Hawai’i): (12 Sep) HVO’s latest warning status update issued yesterday:
“Between September 6 and 10, the June 27th flow advanced north then northeastward at an average rate of 400 m/d (0.25 mi/d). In this way, the flow had advanced approximately 14.5 km (9.0 miles straight-line distance) from the vent, or to within 0.6 km (0.4 miles) of the eastern boundary of the Wao Kele o Puna Forest Reserve, by the afternoon of September 10. At the average rate of advancement of 400 m/day (0.25 mi/day) since September 6, we project that lava could flow from its current location to the northwest edge of Kaohe Homesteads in 1.5 days and to the Pāhoa Village road (government road) in Pāhoa within 14-16 days if lava is not further confined within the cracks and down-dropped blocks within the East Rift Zone of Kīlauea volcano. These estimates will be continually refined as we track this lava flow.”
Further statements made to the Hawaii Tribune-Herald by HVO today:
“Given the current trajectory of the flow as of today, the downhill path would put it more in the center of Pahoa. Where the lava flow goes tomorrow could change things.”
Santiaguito (Guatemala): The volcano continues to feed an active lava flow that passes through a ravine on the SE side of the dome. Its length has reached approx. 3 km, which implies it has been making approx. 30 meters progress per day during the past month.
No significant explosive activity has been noticed recently. Heavy rainfalls have been causing mud flows(lahars).
Fuego (Guatemala): Mild to moderate explosive activity continues with no significant changes over the past weeks, but has been relatively intense.
Yesterday, the volcano observatory reported 16 weak and 14 moderate explosions with ash plumes rising up to 800 m above the crater, that drifted 10-12 km to the west. Incandescent material was seen ejected to 100-150 m above the crater.
Stronger explosions produce shock waves that rattle windows and roofs of houses in the vicinity of the volcano.
