Montserrat Volcano Observatory


Morning Report
Report for the period 4 pm 30 June
to 7 am 1 July 1997
The current alert level is ORANGE


The volcano has been quieter overnight, with two more episodes of enhanced activity and deformation, but no significant pyroclastic flow. Last evening, there were a few hybrid earthquakes and an episode of tremor between 7 pm and 10 pm. There were some more small earthquakes between 4 am and 5 am, and then another tremor episode which is still ongoing.

The tiltmeter shows a continuation of the same pattern, and the tremor may terminate with a period of pyroclastic flows within the next two hours.

It seems likely that the cyclic nature of the activity will continue with repeated periods of pyroclastic flows. People in the safe zones should stay alert and listen to Radio Montserrat. The current area of pyroclastic flow activity makes Mosquito Ghaut and Gages the most likely pathways, 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.
