Activity at the Soufriere Hills volcano has been at about the same level as yesterday. Seismicity continue to be dominated by small- to moderate- sized rockfall signals which during the daytime, is usually associated with small ash plumes. Low-amplitude broadband tremor has been intermittent and variable throughout the night. Tremor level was generally low up until 22:41 on 03 June; it became moderate and intermittent from this time up to about 04:00 on 04 June and has been low ever since. There have also been a few long period events during the night.
Low cloud cover and steam emission prevented any clear views of the summit of the volcano early this morning. Conditions improved significantly at about 06:45; constant steam emission from the growing dome obscured clear views, but ash plumes due to early morning rockfalls were visible.
Scientists at the Montserrat Volcano Observatory view the situation at the Soufriere Hills Volcano with grave concern and urge that visits to the evacuated zone should be kept to a minimum. The Tar River, Long Ground and Whites areas are extremely dangerous, and should not be entered under any circumstances. Given the frequent occurrence of pyroclastic flows in the Tar River valley persons entering this area put themselves at direct risk of serious injury and death.
