Daily Report
Report for the period 6 pm 24 November
to 6 pm 25 November 1997


Today seismic activity was at a s slightly lower level to yesterday with small hybrid earthquakes, long-period events and rockfall signals recorded.

Visibility today was again very poor.

Between 16:00 yesterday and 16:00 today there were 21 long-period earthquakes, 17 hybrid earthquakes, and 55 rockfall signals. The hybrids remained very small again today and many of those observed on the drums did not trigger the networks and so are not included in the count. It has to be assumed that the dome is continuing to grow. This means that pyroclastic flows could occur down any of the ghauts around the volcano with little warning. The level of ash in the atmosphere in St Peter's and in St John's, as averaged over the last 24 hours, has remained low.
