Morning Report
Report for the period 4 pm 23 July
to 7 am 24 July 1997

The alert level system has been revised by zones


Volcano activity overnight has continued to be dominated by small to moderate sized rockfall signals. At about 6:20 am today a small pyroclastic flow occurred down the north-eastern flank of the dome. Broadband tremor, which was generally of a low amplitude, was recorded for variable periods on the St George's Hill station throughout the night.

Low cloud cover, has persisted over the summit of the volcano during the night and early morning and no views of the dome have been possible.

The current area of activity in the crater still makes Mosquito Ghaut and Gages the most likely pathways for pyroclastic flows and surges, but further flows in Tuitt's or Tar River are possible. The Belham River valley is also dangerous and should not be entered. Access to the exclusion zone is completely restricted, and people should stay completely away from the flanks of the volcano. Everyone should continue to stay alert, and listen to Radio Montserrat for any announcements.
