Montserrat Volcano Observatory


Morning Report
Report for the period 16:00 04 April
to 07:00 05 April 1997
The current alert level is ORANGE


The activity at the volcano has been low overnight. It has been dominated by small to medium-sized rockfalls and pyroclastic flows. Only a few hybrid earthquakes have been recorded by the seismic network. Several periods of low amplitude tremor on the Gages seismometer is probably the result of mud flows caused by heavy rain.

Due to the rain overnight and this morning, the volcano is blanketed by cloud and the prospects of good views of the dome are poor.

Although the activity is currently low, changes could happen quickly at any time, and further major pyroclastic flows could result. The alert level remains at orange, and so there should be no visits to zones A and B and only limited, short visits to zone C. Daytime occupation only is permitted in zone D. People should listen for further updates of the situation from the MVO. For the time being people are advised to remain vigilant and to always wear an ash mask in dusty conditions. The Tar River and White River valleys are extremely dangerous, and should not be entered at any time.
