Wednesday Sep 24, 2014 11:05 AM | BY: T
PVMBG reported that although Karangetang was often covered in fog during 7-14 September, observers occasionally noted white plumes rising at most 150 m from the main crater and Crater II.
Incandescence from the lava dome was observed at night. Seismicity remained high and was dominated by shallow earthquakes from lava-dome growth and avalanches. The Alert Level remained at 3 (on a scale of 1-4).
