Montserrat Volcano Observatory

Morning Report
Report for the period 4 pm 26 August
to 7 am 27 August 1997

Activity at the volcano continues at a reduced level. Activity overnight was relatively quiet with the seismic records being dominated by small rockfall signals. The pattern of peaks in activity that developed over the recent weeks is beginning to breakdown further. Overnight there has been no distinct peak in the activity. The rockfalls have occurred throughout the night although activity has been at a low level since around 5 am.

The summit of the volcano is shrouded in cloud this morning. Some incandescence was observed from the observatory last night.

Explosions may take place with little or no warning. These may be more intense and longer lasting than those already experienced. If explosions do occur, people should seek shelter under as strong a roof as possible and have a helmet or head protection available. After an explosion small rocks and ash can be expected to fall everywhere on the island. Ash and falling rocks make driving hazardous. Ash is present in the atmosphere and masks should be worn outdoors.

Pyroclastic flows are expected on all flanks of the volcano, and it is never safe to enter the exclusion zone, including the Belham river valley. Access to the exclusion zone is completely restricted. The access to areas south of the Nantes River is only allowed during the day for essential visits. Everyone should remain vigilant and continue to listen to Radio Montserrat.
