Data from deformation-monitoring instruments indicated that during 22-28 August lava-dome growth at Mount St. Helens continued. Seismicity persisted at low levels, punctuated by M 1.5-2.5, and occasionally larger, earthquakes. Clouds occasionally inhibited visual observations.Show more

MVO reported that during 21-28 August the lava dome at Soufrière Hills changed very little, based on visual observations. Seismic activity was very low and low-level rockfall activity continued. On 23 August, heavy rainfall triggered small rockfalls and four pyroclastic flows to the E down the Tar River Valley. Ash and steam emissions from the dome produced a plume that drifted W. A lahar occurred in the Belham river valley to the NW. The Alert Level remained elevated at 4 (on a scale of 0-5). - More about Soufriere Hills volcano

KVERT reported that seismic activity at Shiveluch was above background levels during 17-24 August. Based on seismic interpretation, avalanches and ash plumes that rose to an altitude of 8.5 km (27,900 ft) a.s.l. occurred during the reporting period. Based on visual observation, ash plumes rose to an altitude of 5.5 km (18,000 ft) a.s.l. and drifted N and NE during 17-21 August. Incandescence at the lava dome and incandescent avalanches were seen at night on 21 August. Observations of satellite imagery revealed that a thermal anomaly was present in the crater during 17-24 August. The Level of Concern Color Code remained at Orange- More about Shiveluch volcano

RVO reported that ash plumes from Rabaul caldera's Tavurvur cone rose to altitudes of 0.9-2.4 km (3,000-7,900 ft) a.s.l. during 22-29 August and drifted NW. Ashfall was reported in Rabaul Town and surrounding areas during 23-29 August. Seismic activity increased to a high level on 25 through 29 August.

Seismic activity at Karymsky was above background levels during 17-24 August, with 300-800 shallow earthquakes occurring daily. Based on seismic interpretation, ash plumes may have risen to an altitude of 5.7 km (18,700 ft) a.s.l.

On 24 August, INSIVUMEH reported that fumarolic plumes from Fuego rose to an altitude of 3.9 km (12,800 ft) a.s.l. and drifted W. A lahar carried tree trunks, branches, and blocks down the Lajas drainage to the SE. A lahar again affected the drainage on 27 August. Explosions on 28 August produced ash plumes that rose to an altitude of 4.1 km (13,500 ft) a.s.l.- More about Fuego volcano

News about an eruption on Ferdinandina Island in the Galapagos archipelago turned out to be wrong. After an earthquake with a 5.2-degree Richter Scale on Tuesday, ash plumes were believed to have originated from a new eruption. As an overflight revieled, the ash plume had been caused by a large rockfall from the inner rim of the caldera and not by an eruption.

Etna is back erupting. Since 15 August 2007, the SE crater has been showing weak explosive activity from the vent in the collapse pit on the E falnk of the SE cone. The activity consits mainly of deep-seated strombolian explosions occurring at irregular intervals of several minutes or more, producing dark to brown ash plumes with some fresh material. - More about Etna volcano

Explosive activity at Sheveluch volcano continues. Ash plumes from explosions rising to 4-6 km are observed by pilots and from satellite. According to Ria Novosti, a possibly much more powerful eruption might have taken place last Tuesday (21 Aug), sending ash to more than 10 km, although it has not been confirmed so far by other data. - More about Shiveluch volcano

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.

As our colleague Andrea Ercolani reports from Stromboli, access to the summit area of Stromboli has been reopened for guided tours under certain restrictions. In brief, small groups accompanied with authorized guides can now reach the ridge east of the crater terrace between 750 and around 850 m elevation where a few shelters are located, but the maximum stay is now limited to 30 minutes. Access to the Pizzo summit itself is limited to the time necessary for passing along the trail.

Parts of the eruptive fissure that opened up east of Pu'u 'O'o on 21 July are still active, feeding spreading 'a'a and pahoehoe lava flows and small lava ponds in the area. No lava has been seen at Pu'u 'O'o itself, which shoows deflation (likely related to draining of lava from the plumbing system).- More about Kilauea volcano
