Ubinas, Peru

Based on SIGMET reports, analysis of satellite imagery, and pilot observations, the Buenos Aires VAAC reported that during 26-27 August and on 2 September continuous ash plumes from Ubinas rose to altitudes of 5.5-6.1 km (18,000-20,000 ft) a.s.l. Plumes drifted N on 27 August and S on 2 September.

Taal, Luzon, Philippines

PHIVOLCS reported ongoing seismic unrest at Taal on 28 August. Ten earthquakes occurred; two at Intensity II were felt by residents in the Pira-Piraso village and were accompanied by rumbling sounds. The earthquakes were located NE of the island near the Daang Kastila area at estimated depths of 0.6-0.8 km. Surface observations indicated no change [...]

Shiveluch, Russia

KVERT reported that seismic activity at Shiveluch was slightly above background levels during 22-29 August. Gas-and-steam plumes with a small amount of ash were generated from avalanches during 22 and 25-28 August. Analysis of satellite imagery revealed a daily thermal anomaly on the lava dome and that steam-and-ash plumes drifted 80 km SE on 26 [...]

Semeru, Eastern Java, Indonesia

Based on pilot observations, the Darwin VAAC reported that a low-level plume from Semeru was present on 28 August. A pilot reported that an ash plume rose to an altitude of 4.6 km (15,000 ft) a.s.l. and drifted SW on 31 August.

Rabaul, Papua New Guinea

RVO reported that ash plumes from Rabaul caldera’s Tavurvur cone continued to be emitted during 29-31 August. The plumes drifted NW and caused ashfall in areas downwind. Continuous incandescence at the summit was observed and roaring noises were heard. Explosions also ejected incandescent lava fragments.

Okmok, Fox Islands, USA

On 27 August, AVO lowered the Volcano Alert Level for Okmok to Advisory and the Aviation Color Code to Yellow because seismicity had declined steadily during 20-27 August and ash plumes had not been observed since 19 August. On 28 August, a thermal anomaly and a steam plume were detected on satellite imagery. Cloud cover [...]

Nyiragongo, Congo

Based on analysis of satellite imagery, the Toulouse VAAC reported that an eruption of unstated character from Nyiragongo occurred before 0300 on 2 September. The activity was not confirmed by ground observations. Nyiragongo’s frequently active lava lake is often detected on MODIS satellite thermal imagery.

Nevado Del Huila, Colombia

INGEOMINAS reported that on 2 September a M 4.6 earthquake at Nevado del Huila was detected 2.2 km NE of Pico Central. The Alert Level remained at Yellow (on a 4-color scale where Yellow is the second lowest).

Llaima, Chile

On 2 September, SERNAGEOMIN reported that clouds had prevented visual observations of Llaima during the previous few days. Explosions were heard during 25-28 August. On 28 August, seismic signals indicated that gas-and-ash plumes were possibly emitted from the pyroclastic cones in the main crater. The Volcanic Alert Level remained at Yellow.
