Activity at the volcano overnight has remained at an elevated level with moderate to large rockfall and pyroclastic flows being recorded for most of the period. High amplitude tremor on the Lees, St George's Hill and Long Ground seismometers died out at about 12:00 midnight with moderate sized rockfalls continuing after this period. A hybrid earthquake swarm with one event per minute began at about 5:30 am today and is still continuing. The ash plume which has been visible drifting towards the west from the volcano has persisted for most of the night and had been replaced during the early morning by steam plumes which were visible from the observatory.
The new ash from the activity yesterday and last night is still in the air in the west of Montserrat and therefore dust masks should always be worn in these areas. Drivers should also be considerate whilst driving in ashy conditions. Although the current area of activity in the crater still makes Tuitt's Ghaut and Gages the most likely pathways for pyroclastic flows and surges, further flows in Mosquito Ghaut or Tar River are possible. The Belham River valley is also dangerous and should not be entered. Access to the exclusion zone is completely restricted, and people should stay completely away from the flanks of the volcano. Everyone should continue to stay alert, and listen to Radio Montserrat for any announcements.
