Roundup of Global Volcanic Activity – New Activity for the week of 18 October – 24 October 2017

Agung | Bali (Indonesia) : PVMBG reported that although foggy conditions at Agung occasionally prevented visual observations, during 18-24 October dense white plumes were seen rising as high as 500 m above the crater rim. Seismicity fluctuated but remained high, though BNPB reported that overall seismicity had decreased. According to BNPB a team launched a drone on 19 October and were able to capture video of the fumarolic emissions from several vents and cracks in the crater. The Alert Level remained at 4 (the highest level on a scale of 1-4) with the exclusion zone at 9 km, and an additional expansion to 12 km in the SE, S, and SW directions.

Aoba | Vanuatu : According to a news article posted on 20 October, residents that had evacuated from Aoba after the eruption from a vent in Lake Voui were returning home. Based on analyses of satellite imagery and model data, the Wellington VAAC reported that during 22-23 October intermittent events generated low-level ash plumes that rose 2.4-3.7 km (8,000-12,000 ft) a.s.l. and drifted E.

Kirishimayama | Kyushu (Japan) : JMA reported that the eruption at Shinmoe-dake (Shinmoe peak), a stratovolcano of the Kirishimayama volcano group, began on 11 October and lasted almost continuously until the morning of 17 October. The eruption plume usually rose several hundred meters about the crater rim, though on 14 October the plume rose as high as 2.3 km. Sulfur dioxide flux exceeding 10,000 tons/day was also recorded. Cloudy weather conditions prevented webcam views during 19-20 October. Plumes rose 200-600 m on 21, 23, and 24 October. During an overflight on 24 October scientists observed a white plume rising from the active vent on the E side of the crater, and puddles in multiple low areas of the crater. The Alert Level remained at 3 (on a scale of 1-5).

Tinakula | Solomon Islands : Based on satellite data, the Wellington VAAC reported that an eruption at Tinakula began around 0620 on 21 October, producing a sulfur dioxide signature, and an ash plume that rose to an altitude of 4.6 km (15,000 ft) a.s.l. and drifted N. Another eruption at 1040 generated an ash plume that rose significantly higher that the first, to an altitude of 10.7 (35,000 ft) a.s.l. and drifted SE. Later that day ash plumes rose to 6.1 km (20,000 ft) a.s.l. Ash emissions continued through at least 24 October, rising to altitudes of 3-3.7 (10,000-12,000 ft) a.s.l. and drifting E and W on 22 October, 2.4 km (8,000 ft) a.s.l. and drifting S and SE on 23 October, and 1.8 km (6,000 ft) a.s.l. with a SW drift on 24 October. A news article from 24 October stated that water supplies in the Reef Islands had been contaminated with ashfall, and that ashfall was also reported in Fenualoa, and likely in Nupani.
