The level of seismic activity has remained low overnight. The predominant signals on the seismic network have been due to small to moderate rockfalls and pyroclastic flows. A period of low amplitude tremor on all stations between 3:50 am and about 4:30 am was followed by the biggest pyroclastic flow signal at 4:50 am. A few small volcano-tectonic earthquakes have also been recorded.
The volcano is currently hidden by low cloud as a result of heavy rain early this morning, and the prospects of clear views of the summit area are not good.
The volcano remains active and dangerous, with a very large dome which could collapse at any time. People should exercise caution when visiting the areas close to the volcano. Further pyroclastic flows and ash clouds are expected, and the situation could escalate rapidly. Ash masks should be worn in the event of ash production. All of Zone A, which includes Long Ground and St Patrick's, is very dangerous and should not be entered under any circumstances.
