Report for Manam
RVO reported that at 1330 on 2 November a single large explosion at Manam generated a dense dark ash plume that rose 1 km above the summit and drifted NW. A shock wave was felt at the Bogia Government station (about 40 km SE) about 1 minute later. RSAM values on 6 November fluctuated between 250 and 360 units but began to increase around 1430 and triggered alerts around 1445. Values continued to increase and reached 400-500 units, heralding an eruption which began during 1600-1630. A gray ash plume rose 1 km and drifted NW. Incandescent material ejecting from the vent was visible at the start of the eruption and became more visible as the evening grew darker. The eruption peaked in intensity around 1930, then declined and ceased during 2100-2200.

Report for Krakatau
PVMBG reported that during 4-10 November diffuse white plumes rose as high as 200 m above Anak Krakatau’s active vent. The seismic network detected 30 eruptive events; dense gray-to-black plumes rose as high as 300 m above the vent. The Alert Level remained at 2 (on a scale of 1-4), and the public was warned to remain outside of the 2-km-radius hazard zone from the crater.

Report for Merapi
PVMBG reported that at 0621 on 9 November an eruption was detected by the seismic network at Merapi and lasted two minutes and 40 seconds. A pyroclastic flow traveled 2 km down the Gendol drainage on the SE flank and an ash plume rose around 1.5 km above the summit. Minor ashfall was reported in areas to the W as far as 15 km away, including Wonolelo, Sawangan, Magelang, and Tlogolele. The event did not notably impact the morphology of the lava dome and the drainage. The Alert Level remained at 2 (on a scale of 1-4), and residents were warned to stay outside of the 3-km exclusion zone.

Report for Sangeang Api
The Darwin VAAC reported that during 6-12 November discrete and short-lived ash emissions from Sangeang Api rose to 3 km (10,000 ft) a.s.l. and drifted NW, W, and SW. Thermal anomalies were visible during 6-8 November. The Alert Level remained at 2 (on a scale of 1-4).

Report for Karangetang
PVMBG reported that during 4-10 November lava continued to effuse from Karangetang’s Main Crater (S) and travel down the Nanitu, Pangi, and Sense drainages on the SW and W flanks. Incandescent blocks from the flows reached a distance of 1.8 km from the crater. Sometimes dense white plumes rose to 250 m above the summit craters. The Alert Level remained at 2 (on a scale of 1-4).

Report for Dukono
Based on satellite and wind model data, and information from PVMBG, the Darwin VAAC reported that during 6-12 November ash plumes from Dukono rose to an altitude of 1.8-2.1 km (6,000-7,000 ft) a.s.l. and drifted in multiple directions. The Alert Level remained at 2 (on a scale of 1-4), and the public was warned to remain outside of the 2-km exclusion zone.

Report for Suwanosejima
JMA reported that incandescence at Suwanosejima’s Ontake Crater was visible during 1-8 November. Very small eruptive events on 5 and 7 November generated grayish white plumes that rose 900 m above the crater rim. The Alert Level remained at 2 (on a 5-level scale).

Report for Aira
JMA reported that incandescence from Minamidake Crater (at Aira Caldera’s Sakurajima volcano) was visible at night during 5-11 November. There were 13 explosions and 25 non-explosive eruptive events detected by the seismic network. Blocks were ejected as far as 1.3 km away. Explosions at 1557 and 1615 on 7 November generated ash plumes that rose 3.8 and 3.5 km above the crater rim, respectively. An explosion at 1724 on 8 November generated an ash plume that rose 5.5 km above the crater rim and drifted E, and ejected large blocks that fell 500-800 m away. The last time plumes rose over 5 km from the active vents was on 26 July 2016 at Showa Crater and on 7 October 2000 at Minamidake Crater. The Alert Level remained at 3 (on a 5-level scale).

Report for Asamayama
On 6 November JMA lowered the Alert Level for Asamayama to 1 (on a scale of 1-5) noting that no eruptions had occurred since 26 August, volcanic tremor had not been recorded since early September, and volcanic gas emissions had been generally low.

Report for Ebeko
Volcanologists in Severo-Kurilsk (Paramushir Island), about 7 km E of Ebeko, observed explosions during 2-6 November that sent ash plumes up to 3 km (10,00 ft) a.s.l. Ash plumes drifted N, E, and SE. The Aviation Color Code remained at Orange (the second highest level on a four-color scale).

Report for Klyuchevskoy
KVERT reported that a weak thermal anomaly over Klyuchevskoy was identified in satellite images on 6 November. The Aviation Color Code remained at Orange.

Report for Sheveluch
KVERT reported that a thermal anomaly over Sheveluch was identified in satellite images during 1-8 November. Ash plumes drifted as far as 640 km NW on 3 and 5 November. The Aviation Color Code remained at Orange (the second highest level on a four-color scale).

Report for Cleveland
Highly elevated surface temperatures identified in satellite data indicated that slow lava effusion in Cleveland’s summit crater may have begun during 7-8 November. AVO raised the Volcano Alert Level to Watch and the Aviation Color Code to Orange. Robust steaming was visible in satellite and webcam images on 7 November.

Report for Shishaldin
AVO reported that the eruption at Shishaldin continued at variable levels during 5-12 November. Periods of high-amplitude tremor during 5-6 November were likely related to increased lava effusion and fountaining, though weather clouds prevented visual confirmation. Intermittent advancement of active lava flows and lahars on the N flank were confirmed in RADAR data, and by 7 November the lava flow was 1.3 km long and the debris flow runout was 5 km. Seismic tremor was low during 8-9 November suggesting lava effusion was less likely; weather cloud cover continued to obscure views, though elevated surface temperatures were sometimes detected during brief periods of clear weather. Activity significantly increased during 10-11 November with lava fountaining visible in webcam views throughout the evening and night. Strongly elevated surface temperatures at the summit and along the flanks were visible in satellite data. Ash emissions reported by pilots and visible on webcam images rose as high as 3.7 km (12,000 ft) a.s.l. and drifted N. Activity decreased during 11-12 November. Strongly elevated surface temperatures were consistent with cooling lava flows. Seismicity decreased during the evening of 11 November and remained low. Minor steam-and-ash emissions were visible in webcam images. The Aviation Color Code remained at Orange and the Volcano Alert Level remained at Watch.

Report for Popocatepetl
During an overflight of Popocatépetl on 5 November CENAPRED scientists, researchers from Instituto de Geofísica de UNAM, and members of the Coordinación Nacional de Protección Civil observed lava dome number 85 in the bottom of the inner summit crater. The dome was 210 m in diameter, 80 m thick, and had an irregular surface. The inner crater remained 350 m in diameter and was 90 m deep. CENAPRED reported that each day during 6-12 November there were 58-148 steam-and-gas emissions, some of which contained ash. Explosions at 0300 and 0501 on 6 November and at 0023 and 0655 on 7 November ejected incandescent tephra onto the upper flanks. Five more explosions were detected on 6 November. Eruptive events at 0858 and 0941 on 9 November generated ash plumes that rose 2 km above the crater rim and drifted NW; between those two ash emissions explosions were recorded at 0923 and 2055. Explosions on 10 November were recorded at 0648 and 1636. An explosion at 2203 on 11 November ejected incandescent tephra as far down the E flank as 1.5 km and generated an ash plume that rose 2 km and drifted NE. The Alert Level remained at Yellow, Phase Two (middle level on a three-color scale).
