Thermal anomalies are visible at Ibu volcano (Halmahera, Indonesia), suggesting eruptive activity at the summit, possibly related to lava dome growth in the wide summit crater that has been documented since 2000.
A small swarm of shallow quakes has been occurring today at Kilauea volcano on Hawai'i in an area about 6 km SE of the caldera under the eastern rift zone.
The summit lava lake rose yesterday afternoon and has been steady since.
At Pu`u `O`o, the lava lake in the northeast pit was active, and small lava flows were erupted from a spatter cone on the southern side of the crater.
Lava flows southeast of Pu`u `O`o continued to be active on the coastal plain near the base of the pali. Seismic tremor levels were low, and gas emissions were elevated.
The number of (mostly weak) explosions of Popocatépetl volcano in Mexico remains elevated compared to most of the previous weeks. Some of the explosions produce ash plumes up to about 1 km height. Incandescent ejecta are sometimes seen at night and the volcano produces a strong SO2 plume.
Fuego volcano in Guatemala has had only effusive activity since yesterday, and the lava flow is now 800 m long.
Elevated number of earthquakes including a felt magnitude 3 event on 17 Oct have been recorded at Cerro Machin volcano.
Nevado del Ruiz volcano continues to produce a significant steam plume which sometimes contains ash. Seismic activity remains elevated.
Nevado del Huila continues to show weak seismic activity and is steaming.
Weak seismic unrest (100 events counted during a week) continues at shallow depth under Sotará volcano.
More earthquake swarms occurred at Cumbal volcano on 9 October between 1:00 pm and 6:30 pm with approximately 50 events, and between 7:00 pm on Oct. 11 and 6:00 am on October 12 with 112 earthquakes.
Low-energy seismic activity continues at fluctuating levels and there are sometimes small gas and ash emissions from Galeras volcano.
After a day of repose on 16 Oct, Sakurajima volcano has been busy with 5 moderate explosions over the past 24 hours, with maximum ash plumes reaching 10,000 ft (3 km) altitude.
The reported submarine eruption Fukutoku-Okanoba was false. The last eruption of the volcano was in 2010.

A new submarine eruption was observed from Fukutoku-Okanoba volcano in the Volcano Islands of Japan on Tuesday morning, October 16th. Japanese Coast Guard observed a column of white smoke rising from the sea about 3 miles from Minami-Iwoto island. According to a report "the volcano spewed ash and smoke about 100 meters into the air, and the surrounding sea area changed to a yellowish-green color while other parts became a cloudy gray". ...

Activity of Popocatépetl volcano in Mexico is on a slightly increasing trend with 48 exhalations of low to medium intensity during 14-15 Oct, some of which were accompanied by small emissions of ash. The largest produced plumes rising 1.5 km above the crater. Crater glow is visible at night. ... [details]
