Morning Report
Report for the period 16:00 24 May
to 07:00 25 May 1997
The current alert level is ORANGE


The hybrid swarm which began at 12.18pm yesterday continued until about 5pm and was followed by a period of sustained pyroclastic flow activity until about 9pm. This is a continuation of the pattern in volcanic activity which has developed over the last week or so. Overnight there have been regular rockfalls and small pyroclastic flows.

There is little ash this morning but the wind is still blowing from the south east so an increase in volcanic activity could lead to ash fall in the safe zone. The volcano is obscured by cloud again this morning.

Volcanic activity is still concentrated on the northern side of the dome with rockfall debris banking up against the northern wall. The probability of pyroclastic flows breaking into Mosquito, Tuitt's and White's Ghauts remains high. Visits to the central corridor should be restricted to those that are absolutely essential, and it should not be used as a route to the airport. The Tar River and Long Ground areas are extremely dangerous, and should not be entered.
