Worldwide Volcano News and Updates

Servicio Nacional de Geología and Minería (SERNAGEOMIN) Observatorio Volcanológico de Los Andes del Sur (OVDAS) and ONEMI reported the continuing, slow growth of the lava dome in Nevados de Chillán's Nicanor Crater during 30 October-6 November. Seismicity was characterized by moderate levels of long-period and tremor events, often associated with explosion signals. Gas emissions persisted, and sometimes contained ash. Read all

PVMBG reported that during 26 October-1 November the lava dome in Merapi's summit crater grew slowly at a rate of 2,900 cubic meters per day, slower than the previous week. By 31 October the volume of the dome, based on photos from the SE sector, was an estimated 248,000 cubic meters. White emissions of variable density rose a maximum of 50 m above the summit. Read all

PVMBG reported that a 37-second-long event at Anak Krakatau at 0223 on 6 November generated an ash plume that, based on a ground observation, rose 500 m and drifted N. At 1000 a dense ash plume rose 600 m above the summit and drifted N. The Alert Level remained at 2 (on a scale of 1-4); residents and visitors were warned not to approach the volcano within 2 km of the crater. Read all

INSIVUMEH and CONRED reported an increase in seismicity and in the number of explosions at Fuego on 31 October. Ash plumes during 31 October-5 November rose 1 km above the summit and drifted 15 km W and SW. Ashfall was reported in areas downwind including Morelia (9 km SW), Santa Sofia (12 km SW), Sangre de Cristo (8 km WSW), Panimaché (8 km SW), and San Pedro Yepocapa (8 km NW). Read all

INGV reported that during 29 October-4 November activity at Etna was characterized by gas emissions at the summit craters, with periodic Strombolian activity from vents in Bocca Nuova, Northeast Crater (NEC), SE Crater (SEC), and New Southeast Crater (NSEC). Strombolian explosions at NSEC were interspersed with long pauses from a few minutes to a few hours. The explosions sometimes produced ash emissions that quickly dispersed; ashfall was deposited around the crater and in the Valle del Bove. Read all

Volcanologists in Severo-Kurilsk (Paramushir Island), about 7 km E of Ebeko, observed explosions during 26 October-2 November that sent ash plumes to 3.7 km (12,400 ft) a.s.l. Ash plumes drifted in multiple directions and caused ashfall in Severo-Kurilsk during 29-31 October. A thermal anomaly was visible in satellite images on 24 and 29 October. Read all

Based on satellite data, wind model data, and notices from PVMBG, the Darwin VAAC reported that during 30-31 October ash plumes from Dukono rose to an altitude of 2.1 km (7,000 ft) a.s.l. and drifted W and N. Read all

JMA reported that at 1022 on 30 October an event at Minamidake crater (at Aira Caldera's Sakurajima volcano) generated a plume that rose 1 km above the crater rim. Two explosions occurred during 2-5 November; the larger of the two sent a plume to 2.6 km and ejected material as far as 700 m from the crater. The Alert Level remained at 3 (on a 5-level scale).

KVERT reported that an ash explosion at Sarychev Peak was last noted on 10 October and a thermal anomaly was last identified on 15 October. The volcano was quiet or obscured by clouds during 16-31 October. KVERT lowered the Aviation Color Code to Yellow (the second lowest level on a four-color scale). Read all

JMA reported that during 31 October-5 November there were very small events recorded at Kuchinoerabujima's Shindake Crater. Plumes rose 500-1,200 m above the crater rim. The Alert Level remained at 3 (on a scale of 1-5). Read all
