Volcanic activity at the Soufriere Hills volcano during the night has continued at about the same level as observed during the day time. Seismicity continues to be dominated by small- to moderate-sized rockfall signals. Some light ashfall was associated with the event of 05:04 on the 16 May. Small hybrid signals continue to be recorded at the Gages and Chances Peak seismic stations with the period 15:50 to 19:00 on the 15 May being the most intense. A few Vts and long period events were also recorded during the night.
Low cloud cover continue to obscure the top of the volcano and no clearviews were obtained from the Observatory or Brambles Airport.
The MVO still views the situation at the Soufriere Hills Volcano with grave concern and the scientists continue to urge that visits to the evacuated zone be kept to a minimum. The Tar River, Long Ground and Whites areas are extremely dangerous, and should not be entered under any circumstances.
