A possible explosion or partial lava dome collapse produced a modest ash plume yesterday rising to 12,000 ft (3.7 km) altitude (VAAC Tokyo). KVERT reports no significant changes and continues to record moderate tremor levels, indicating that magma continues to rise and slowly build up the lava dome.

KVERT reports no significant change in the activity (seismic and surface). Lava flows continue to effuse from the southern fissure. Tremor remains high, although it has continued to slowly decrease. ...plus
samedi, avril 06, 2013
Moderate seismic activity and weak shallow earthquakes were registered. Hot avalanches (collapse of parts of the growing dome) and possibly explosions accompanying this process produced a plume rising to 20,000 ft (6 km) altitude yesterday. Strong degassing and steaming are continuous.
mardi, avril 02, 2013
No changes in activity occurred. Moderate seismic activity accompanies ongoing lava dome growth, KVERT mentions.

An ash plume, presumably from an explosion at the dome, rose to 19,800 ft (6.0 km) altitude yesterday, KVERT reported. Seismicity continues to be moderate, and strong steaming-degassing accompanies the process of the lava dome growth.

mercredi, mars 06, 2013
Several (3 or 4) relatively larg collapses of the lava dome occurred today between between 05:00 and 06:30 (GMT). The events triggered pyroclastic flows which traveled through the valley between the active dome and a relict flank of an older dome to the east. The largest flow reached about 4 km distance. ...plus

A viscous lava flow continues to effuse on the eastern flank of the lava dome. Strong and moderate fumarolic activity and incandescence of the dome summit and hot avalanches accompanies this process. (KVERT weekly update).
mardi, févr. 26, 2013
KVERT reports only weak seismic activity today, indicating the volcano is in a phase of lower activity.

mardi, févr. 19, 2013
A possible ash explosion sent ash up to 16,500 ft (5.0 km) a.s.l. KVERT registered moderate seismicity, but clouds obscured the view of the volcano.
dimanche, févr. 17, 2013
KVERT reports moderate seismicity and a thermal anomaly over the volcano visible on satellite data, indicating that the lava dome remains active.

A viscous lava flow continues to effuse on the eastern flank of the lava dome, strong and moderate fumarolic activity and incandescence of the dome summit and hot avalanches accompanies this process. Satellite data showed a thermal anomaly over the lava dome. (KVERT) ...plus
lundi, janv. 21, 2013
The lava dome continues to grow. A moderate explosion occurred last night, producing an ash plume that rose to between 8,000 ft (1.8 km) (VAAC Tokyo) and 13,000 ft (4 km) (KVERT) altitude. ...plus
vendredi, janv. 11, 2013
Explosive-extrusive-effusive eruption of the volcano continues. According to visual and satellite data, a viscous lava flow continues to effuse on the north-western flank of the lava dome, strong and moderate fumarolic activity and incandescence of the dome summit and hot avalanches accompanies this process. ...plus [lire toutes]

Activity continues to build the lava dome which sheds hot avalanches from time to time. Incandescence above the summit of the lava dome was observed. Satellite data shows a thermal anomaly over the volcano. Moderate seismicity and strong degassing accompany this activity. (KVERT)
