Activity at the volcano since yesterday has been at about the same level with rockfalls being the main phenomena recorded by the seismic network. A hybrid earthquake swarm which lasted for about one hour began at 8:00pm last night. Visibilitiy improved significantly at about 4:00am this morning and allowed a good view of the dome from the Observatory. Incandescent blocks were observed falling from five active channels above Gages through to Mosquito Ghaut. The area above Gages was the most active.
The tiltmeters on Chance's Peak continue their cyclic pattern with another cycle which peaked at about 8:00 pm, experienced last night. No pyroclastic flow activity was observed to be associated with this tilt cycle.
People are reminded that hot mudflows can be extremely hot if recent deposits are remobilised by heavy rain. The current area of activity in the crater makes Mosquito Ghaut and Gages the most likely pathways for pyroclastic flows and surges, but further flows in Tuitt's or Tar River are possible. The Belham River valley is also dangerous and should not be entered. Access to Plymouth 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.
