Montserrat Volcano Observatory


Morning Report
Report for the period 4 pm 30 July
to 7 am 31 July 1997

The alert level system has been revised by zones


Activity at the volcano overnight has been elevated with many moderate to large pyroclastic flows probably over Gages wall towards Plymouth since about 3 am this morning. The activity built up from back ground level with no warning and is continuing at the time of reporting. At times the signals are at maximum amplitude on many of the stations. As a result of the activity there is a lot of ash in air, and this is drifting to the north and north-west in light winds. So people should use their ash masks whenever there is ash in the air. People should also be considerate whilst driving since the ash is dry and can make driving difficult.

Although the current area of activity in the crater still makes Mosquito Ghaut and Gages the most likely pathways for pyroclastic flows and surges, 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.
