Volcanic activity at the Soufriere Hills Volcano has been at a lower level today and is still dominated by small to moderate-sized rockfalls.
Small- to moderate- sized rockfall signals continue to dominate seismicity at the volcano. There were only 13 of these events during this reporting period, a decrease compared with yesterday. The largest rockfalls were recorded at 17:49 and 18:58 on 6 June and 00:09 and 15:00 on 7 June. Very poor visibility prevented observation of any ash clouds that may have been associated with these events. There was one hybrid event today and no long period earthquakes. There have been brief periods of intermittent low-amplitude broadband tremor throughout the reporting period.
No views were obtained of the volcano today. Very low cloud cover and generally overcast conditions prevented any views of the volcano throughout the day.
No EDM measurements were made due to the poor weather conditions.
COSPEC measurements of the SO2 gas concentration in the volcanic plume were carried out between Kinsale and Weekes. The results are currently being processed.
Rainfall collectors and SO2 tubes were installed at Gages, Cork Hill, Amersham, Plymouth and at the Observatory at Old Towne. These devices would be used to monitor the air and water quality for health purposes.
Scientists at the Montserrat Volcano Observatory continue to view the situation at the Soufriere Hills Volcano with grave concern. Visits to the evacuated zone should be kept to a minimum. The Tar River, Long Ground and Whites areas are extremely dangerous due to the frequent occurrence of pyroclastic flows in the Tar River valley. People should not enter these areas under any circumstances. If they do, they put themselves at direct risk of serious injury or death.
