Morning Report
Report for the period 16:00 14 May
to 07:00 15 May 1997
The current alert level is AMBER


Volcanic activity has been slightly less energetic overnight than the preceding 72 hours or so. This is evident from a reduction in the number of seismic events recorded since 4:00 pm yesterday. Despite the slight reduction, a variety of events continue to occur, composing of rockfalls, long period and hybrid earthquakes, small pyroclastic flows, steam and gas emissions, and the occasional volcano-tectonic earthquake.

The top of the volcano remains obscured by low cloud cover this morning.

Whilst dome growth continues at the Soufriere Hills volcano, it remains dangerous. Recently, there has been a slight surge in the number of rockfalls, indicating that the dome may be approaching the limits of stability. Pyroclastic flows and surges are again becoming more likely and could occur without warning in the Tar River or White River valleys. People should stay well away from these areas. Visitors to Zone C should equip themselves with protective gear and stay alert.
