Daily Report
Report for the period 6 pm 1 December
to 6 pm 2 December 1997


At around 8 O'clock last night there was a pyroclastic flow down Galways. After the flow, glowing was observed from the south side of the dome. Since then seismicity has been at a low level with mainly rockfall signals being recorded. Visibility has been poor today and no further observations of the volcano have been made.

Between 16:00 yesterday and 16:00 today there were 32 long-period earthquakes, 88 rockfall signals, including the pulses of the pyroclastic flow, and 11 hybrid earthquakes. The flow was relatively small and did not last for as long as the flow on Thursday. The glowing observed from the dome last night means that the dome is continuing to grow and that the current focus of growth is still on the south side. However, past experience has shown that the area of growth on the dome can change very fast and pyroclastic flows could occur down any of the ghauts around the volcano with little warning.

Average dust levels over the last 24 hours in St. Johns, St. Peters and Woodlands were low.
