Montserrat Volcano Observatory


Morning Report
Report for the period 16:00 10 May
to 07:00 11 May 1997
The current alert level is AMBER


Activity at the volcano has continued at a low level overnight, with seismic signals generated from rockfalls and small pyroclastic flows dominating the records. Long period earthquakes are also being recorded at the same relatively high level as over the past few weeks - many of these immediately precede rockfalls.

Low cloud is currently obscuring the upper parts of the volcano.

Whilst dome growth continues at the Soufriere Hills volcano, it remains dangerous. Pyroclastic flows and surges could occur at any time and without warning in the Tar River or White River valleys, and people should stay well away from these areas. Rapid changes in the style of activity and areas affected are possible. Visitors to Zone C should thus stay alert and are reminded to stay well clear of ghauts in the event of heavy rain and also to wear masks in ashy conditions.
