Morning Report
Report for the period 16:00 26 April
to 07:00 27 April 1997
The current alert level is AMBER


Volcanic activity has remained at a low level overnight. There have been rockfalls and small pyroclastic flows at a similar level to yesterday. They have been occurring in the upper White River area as the dome above the Galway's Wall continues to grow. Small amounts of ash have been generated by these rockfalls and flows and this is being blown westwards by the wind over the Plymouth area. Long period earthquakes continue to occur and many of these act as triggers for rockfalls. VT and hybrid earthquake activity remains at a very low level.

The summit area of the volcano is cloud-covered at present so that no views of the dome have been possible thus far today.

The volcano remains in a dangerous state and rapid changes in the level of activity are still possible. All citizens of Montserrat are requested to stay alert, especially when in Zone C. People should wear ash masks when in ashy environments. All of Zone A, which includes Long Ground and St Patrick's, is still very dangerous and should not be entered under any circumstances.
