Volcanic activity since yesterday continued the cyclic pattern established several weeks ago. Another hybrid earthquake swarm was recorded during the period. This ended at about 8:00 pm last night and was followed by a few large rockfall signals. Since then seismicity has been very quiet.
The tiltmeters on Chance's Peak continue their cyclic pattern with another peak experienced at a little after 8:00 pm. No pyroclastic flow activity was observed to be associated with this tilt cycle but there were a few large rockfall signals. The interval between successive peaks in the cycle has lengthened to approximately 16 hours.
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.
