Observations of the volcano from the helicopter today indicate that the area of dome growth remains in the Galways area with several large blocks observed on the talus slope. Light ashfalls was reported in Salem and Woodlands today. This was due to the increase in rockfall activity coupled with the wind direction.
A long occupation GPS survey was undertaken between Harris Lookout and Old Town - the results are currently being processed. The results of the survey carried out yesterday between Harris Lookout and Tar River did not show any major changes from established trends.
Dust levels at all monitoring stations were low today.
