Montserrat Volcano Observatory

Daily Report
Report for the period 16:00 04 May
to 16:00 05 May 1996

The level of activity at the Soufriere Hills volcano during this period has remained at the slightly reduced level seen during the previous 24 hours. Seismicity continues to be characterised by intermittent low amplitude broadband tremor recorded at the nearest seismic stations and small rockfalls, with the largest of these at 13:11 on 05 May. A few small hybrid earthquakes and long period events were recorded.

No EDM measurements were made today because of low cloud cover on the mountain. The southern GPS lines were reoccupied, but the results are not yet available.

Further COSPEC measurements were made today and that data is still being processed.

Visibility has been very poor all day and no observations of the dome have been possible.

Glen Matiolli and Ellen Howell of the University of Puerto Rico (UPR) arrived in Montserrat yesterday. They will be reoccupying the established UPR GPS network in order to study any long-term deformation of the volcanic edifice.

The MVO still views the situation at the Soufriere Hills Volcano with grave concern and the scientists continue to urge that visits to the evacuated zone be kept to a minimum. The Tar River, Long Ground and Whites areas are extremely dangerous and should not be entered under any circumstances.
