Worldwide Volcano News and Updates

RVO reported that activity at both Manam's Southern Crater and Main Crater was low during 16-30 November; white vapor emissions rose from both craters. Incandescence from Southern Crater was visible on 28 and 30 November, and on 30 November diffuse gray ash plumes rose from the crater. Read all

During 27 November-3 December HVO reported that the circulating lava lake occasionally rose and fell in the deep pit within Kilauea's Halema'uma'u Crater. The plume from the vent continued to deposit variable amounts of ash, spatter, and Pele's hair onto nearby areas. At Pu'u 'O'o Crater, glow emanated from spatter cones on the N and S portions of the crater floor. Read all

JMA reported that three explosions from Sakura-jima's Showa Crater ejected tephra as far as 800 m during 29 November-2 December. On 29 November an explosion ejected tephra, up to 1 cm in diameter, 4 km away. The Alert Level remained at 3 (on a scale of 1-5).The Tokyo VAAC reported that during 29-30 November, and 1 and 4 December, explosions generated plumes that rose to altitudes of 2.1-2.7 km (7,000-9,000 ft) a.s.l. and drifted E and SE.

Based on webcam data and wind data, the Darwin VAAC reported that during 28-31 November and 2 December ash plumes from Sinabung rose to altitudes of 3-5.5 km (10,000-18,000 ft) a.s.l. Ash plumes drifted 150 km W during 30-31 November and 55 km Won 2 December. On 3 December ash plumes rose to an altitude of 8.2 km (27,000 ft) a.s.l. and drifted W. Read all

Based on visual observations and analyses of satellite data, KVERT reported that during 22-29 November a new lava dome extruded onto the NW part of Shiveluch's older lava dome. Moderate ash explosions generated ash plumes that rose to altitudes of 4-5 km (13,100-16,400) a.s.l. Lava-dome extrusion was accompanied by hot avalanches, incandescence, and fumarolic activity.

KVERT reported that moderate seismic activity continued at Kliuchevskoi during 22-29 November. Video data showed Strombolian activity during that period. Satellite images recorded a daily thermal anomaly on the volcano; gas-and-steam plumes containing small amounts of ash were visible drifting 90 km SE on 25 November. Read all
