Daily Report
Report for the period 16:00 05 May
to 16:00 06 May 1996

Activity at the Soufriere Hills Volcano during this period has been slightly higher than during the previous 24 hours. Seismicity continues to characterised by intermittent low amplitude broadband tremor recorded at the seismic stations nearest to the volcano and many small- to moderate-sized rockfalls. A few small hybrid earthquakes were also recorded.

The EDM lines Amersham - Amersham, Amersham - Dagenham and Amersham - Chance's Peak Steps were measured today. These have lengthened on average by 1.7 to 2.8 cm compared to the last measurements made on 12 April 1996. Re-occupation of the University of Puerto Rico GPS sites at Reid's Hill, St. George's Hill, Radio Antilles (Ogarro's) and Tar River started yesterday and the data is still being processed.

No COSPEC measurements were made today because of the inclement weather.

No visual observations of the dome have been possible because of the low cloud cover on the volcano.

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.
