The volcanic activity remains at a relatively low level, with rockfall signals being the dominant activity on the volcano.
Between 16:00 yesterday and 16:00 today, the broadband seismic network recorded 71 rockfall signals, 26 long period, and 14 hybrid earthquakes. Fifteen of the long-period events were accompanied by rockfall signals. This activity is consistent with steady continuing dome growth.
The dome cleared late this afternoon, and good views were obtained from the ground at Jack Boy Hill and in Old Towne. The northern and western sectors of the dome showed no sign of activity, and a plume of steam and ash continues to emanate from the top of the dome above the Galways growth area.
Dust levels in St. Johns, Woodlands and St. Peters remain low.
Although activity is still mainly focused in the southern central part of the volcano, the area of growth on the dome can change very quickly. Growth activity appears now to be backing up behind the major build-up of material in Galways, and a renewal of rockfalls or pyroclastic flows down Gages or Tar River would not be a surprise in the near future.
