Morning Report
Report for the period 16:00 09 April
to 07:00 10 April 1997
The current alert level is AMBER


The level of seismic activity has remained low overnight. The only seismic signals have been a few moderate rockfalls. The largest of these events occurred just before 5:00am. A teleseismic event was also recorded by the seismic network overnight from an earthquake some distance away. There was a short period of low amplitude tremor on the Gages seismometer between 7:00pm and 9:30pm last night.

The volcano is clear of cloud at the moment but visibility is hindered by the steam plume which continues to be produced from the dome. The outlook for visibility does not look as promising as it has over the past four days.

The volcano remains active and dangerous, with a very large dome which could begin to 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.
