Activity at the Soufriere Hills Volcano overnight remained at a relatively low level. A number of small rockfall signals were recorded but there were only a few moderate-sized ones. The largest of these occurred at 04:14 this morning. Low-amplitude broadband tremor was recorded from 21:20 on 20 June until about 04:00 on 21 June.
No views of the crater area or the upper reaches of the ghauts have been possible this morning due to cloud cover.
Despite the low level of activity, the Soufriere Hills Volcano is still potentially lethal to people and property on both the eastern and upper western flanks . The lava dome continues to grow and is still unstable. It will produce deadly pyroclastic flows into the ghauts that lead from English's Crater. The Tar River, Long Ground and Whites areas to the east and upper Fort Ghaut, Gages Village and Upper Amersham areas to the west are all extremely dangerous. The road between Lee's Estate and Ryners Village remains closed. People should not enter these areas under any circumstances. If they do, they put themselves and others at direct risk of very serious injury or death. Visits to the rest of the evacuated zone should be kept to an absolute minimum.
