Montserrat Volcano Observatory


Morning Report
Report for the period 4 pm 14 July
to 7 am 15 July 1997

The alert level system has been revised by zones


Activity at the volcano has been at about the same level since yesterday. Rockfalls were the only type of events recorded by the seismic stations. The frequency of the rockfall signals has increased slightly since yesterday. Rockfalls and small pyroclastic flows continue to occur at any time with no clear correlation with the Chances Peak tiltmeter which now shows no obvious cyclical behaviour.

The volcano is overcast early this morning and no views of the summit are possible yet.

People are reminded that mudflows can be extremely hot if recent deposits are remobilised by heavy rain. The current area of activity in the crater still 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.
