The Japan Meteorological Agency (JMA) reported ongoing eruptive activity at Minamidake Crater (Aira Caldera?s Sakurajima volcano) during 9-16 February. Crater incandescence was visible in webcam images throughout the week, and small eruptive events occasionally occurred. The Alert Level remained at ...

The Alaska Volcano Observatory (AVO) reported that slow lava effusion continued to feed a thick flow in Great Sitkin?s summit crater during 11-18 February. Radar data on 11 February indicated that slow growth was concentrated near the vent area. Seismic activity was low during the week, with occasio...

According to the Darwin Volcanic Ash Advisory Center (VAAC) eruptive activity at Heard Island?s Big Ben volcano produced an ash plume that was identified in satellite images at 1900 on 11 February rising to 7.3 km (24,000 ft) a.s.l. and drifting NE, based on analysis by the Toulouse VAAC. Ash was no...

The Pusat Vulkanologi dan Mitigasi Bencana Geologi (PVMBG) reported that activity at Ibu continued during 12-18 February with daily eruptive events recorded, except on 17 February. White-to-gray or gray ash plumes rose 300-600 m above the summit and drifted in multiple directions. Incandescence at t...

The Philippine Institute of Volcanology and Seismology (PHIVOLCS) reported continuing eruptive activity at Kanlaon during 11-19 February. The seismic network recorded 2-24 daily volcanic earthquakes; on 13 February two periods of tremor, 15 and 17 minutes long, were also detected. Daily steam-and-ga...

The Hawaiian Volcano Observatory (HVO) reported that the eruption within Kilauea?s Kaluapele summit caldera, characterized by episodic fountaining, incandescence, and intermittent spatter from craters along the SW margin of Halema?uma?u Crater, continued at variable levels during 12-18 February. Inc...

The Pusat Vulkanologi dan Mitigasi Bencana Geologi (PVMBG) reported ongoing eruptive activity at Lewotolok during 12-18 February. White plumes rose as high as 50 m above the summit and drifted NE and E during 12 and 16-17 February; emissions were not visible on the other days. Webcam images though t...

The Pusat Vulkanologi dan Mitigasi Bencana Geologi (PVMBG) reported that an eruptive event at Marapi (on Sumatra) was recorded at 1053 on 18 February.
