The overall level of activity has remained low for the last 24 hours, with rockfalls from the lava dome being the most dominant events.
Like yesterday, earthquake activity has been at a generally low level. There have been 10 hybrid, one long period and no volcano tectonic earthquakes during the reporting period. A total of 79 rockfalls and small pyroclastic flow signals have been recorded, most between 7:00 pm yesterday and 1:00 am this morning. Of these events 79 about a dozen or so were sufficiently energetic to produce small ash clouds.
Severely overcast conditions at the volcano prevented views and field work for most of the day. COSPEC measurements made this afternoon along the road between Cork Hill and Kinsale. The results are still being processed.
Despite the low level of activity the volcano still remains in a potentially perilous state. Further dome growth will continue to destabilise the existing structure producing more pyroclastic flows. The northern flanks of the volcano are still active and hence Tuitt's, Mosquito or White's Ghauts remains dangerous. Large pyroclastic flows could occur with little warning in the Tar River and White River valleys. Nobody should enter zones A and B, and only essential visits should be made to the evacuated zone. Ash masks should be worn when in the ashy areas.
