Ol Doinyo Lengai, Tanzania, Africa
An eruption of Ol Doinyo Lengai on 4 September produced an ash plume that was reported by a pilot and visible on satellite imagery. Ashfall lasted about 12 hours in the village of Engare Sero, about 18 km N. Dark areas on the NW, W, and E flanks that were noticeable on satellite imagery from 4 September were possibly due to recent lava flows and burned vegetation or both. An ash plume was also visible, drifting SSW.
Multiple thermal anomalies at and around the summit were present on satellite imagery since 21 August 2007, and on the flanks on 31 August and 1 September.

Arenal, Costa Rica
In August, activity originating from Arenal's Crater C consisted of gas emissions, sporadic Strombolian eruptions, lava flows traveling down the SW and S flanks, and occasional avalanches from lava-flow fronts. Volcanic activity was at relatively low levels and few eruptions occurred. Blocks from the lava-flow fronts periodically reached vegetation and started small fires. Acid rain and small amounts of ejected pyroclastic material affected the NE and SE flanks. Eruptions produced ash plumes that rose about 2.2 km (7,100 ft) a.s.l. Pyroclastic cones on the NE and SW flanks continued to grow. Small avalanches of volcanic material traveled down several ravines. Crater D showed only fumarolic activity.

Poás, Costa Rica
OVSICORI-UNA reported that during August, Laguna Caliente, a summit lake of Poás, was greenish-gray in color, exhibited convection cells in the lake's center, and contained dark gray floating particles. Subaqueous fumaroles at the center of the lake released gases that spread and covered the entire surface of the lake. The level of the lake had dropped 59 cm with respect to its level in July, and it had a temperature of 58 degrees Celsius. Fumarolic activity from a pyroclastic cone produced gas plumes that rose 400 m above the floor of the crater. Points of gas discharge were noted from the N and NW crater walls, the terrace, and the NE edge of the crater. Fumaroles in contact with the lake and the NE wall produced sulfur particles that floated in the lake. Emissions from the SE and NE crater walls were very low in volume.

Manda Hararo, Ethiopia
A large sulfur dioxide plume and several thermal anomalies from Manda Hararo were detected in satellite imagery on 13 August. On 16 August, a field team conducted aerial and ground observations of a locality known as Karbahi, a graben area with numerous active faults, fissures, and basalt flows, NW of the center of Manda Hararo. Observations revealed active volcanism, including isolated areas of intense gas emission and visible sulfur deposits. Basaltic lava flowed from long fissures, predominantly to the W of the graben floor. Each fissure was covered by a continuous row of small and closely spaced spatter and scoria cones 2-10 m high. Spatter and scoria deposits ranged in size from coarse lapilli to bombs. Incandescence and occasionally small flames were emitted from the tops of some of the cones.
Observed 'a'a and pahoehoe flows traveled a few hundred meters from the vents. The overall thickness of the flows varied but reached several meters in places. Lava channels and lava tubes were abundant. Fault scarps with fresh breaks and rockfalls were noted. The area affected by tectonic and volcanic activity was an estimated 5-7 km long and 1 km wide.
According to eye-witness accounts, a cracking sound was heard and a tremor was felt on 12 August. On 13 August, "fire" was seen that lit up a large area. "Fire and smoke" continued with variable intensity until 16 August. No damage to life or property was reported.

On the S part of the island, scorched vegetation was observed and dead marine life (mainly reef fish) was seen around the coast line at heights of 4-6 m a.s.l. There was no evidence of fresh volcanic material, but a new landslide scar extended from the upper most part of the island down to sea level. Several more landslide scars were seen on the W wall. The estimated wave surge height resulting from the 19 May event reached 4-10 m, particularly around the S part of the island. Rockfalls continued to produce plumes that could be seen from a distance.

San Miguel, El Salvador
Servicio Nacional de Estudios Territoriales (SNET) reported on 10 October that an Alert Level for San Miguel was established as Green within 4 km from the center of the crater due to
a slight increase in seismic activity. On 15 October, the Alert Level was increased to Yellow due to further increases in seismic activity, but then decreased to Green again the next
day.

Simbo, Solomon Islands
Residents on Simbo Island reported feeling seven "earth tremors" on 21 September, and others in recent days. None of the events caused damage. The Solomon Islands Seismology Division
does not have monitoring equipment on the island.
Simbo is a small island in the Western Solomons with three truncated andesitic volcanic centers. The only known Potassium-Argon date suggests a Pliocene-to-Pleistocene age for the
island, although the southern half of the island is thermally active. Fault-related fumarolic areas and hot springs are found near saltwater Lake Ove along the western coast and along
the eastern coast near Mount Patukio, which has a steep-walled summit crater. Grover (1955) noted native accounts of the explosive enlargement of the Ngusunu explosion crater along
the SW coast of the island one to two generations prior to 1955, probably after a visit by Guppy in 1882. Press reports mentioned an eruption at Simbo in the early 1900s that forced
the evacuation of villages beside Lake Ove, immediately adjacent to Ngusunu crater.

Raoul Island, New Zealand
The Alert Level at Raoul Island was lowered to 0 (on a scale of 0-5) on 18 September due to a general decline in activity. Since April 2006, no significant earthquake activity had
occurred within ~30 km of the island, the water in Green Lake dropped to the pre-eruption level, and on-going hydrothermal activity returned to normal.

Augustine, Cook Inlet, Alaska USA
AVO reduced the Concern Color Code at Augustine from Yellow to Green on 9 August. Seismic, satellite, and visual data indicated a decrease in activity to background levels. No changes
were seen at the summit during the previous several months. AVO warned that the lava dome and surrounding area were still unstable despite the apparent cessation of lava-dome growth.
Rockfalls and avalanches were still occurring, especially on the N flank, and may continue for several weeks or months.
