The level of activity at the Soufriere Hills volcano continues to be relatively low, with signals indicative of small- to moderate-sized rockfalls dominating the seismic records. Rockfalls at 16:05 on 18 July and 06:22 on 19 July resulted in very small ash clouds which could be seen drifting to the northwest of the volcano, towards Upper Gages, Amersham and Plymouth. Several small long-period events were also recorded. Intermittent, low-amplitude broadband tremor was recorded by the Gages seismic station throughout the period. This low-amplitude broadband tremor was nearly continuous on the Gages record during the period 22:23 on 18 July and 01:50 on 19 July. This is most probably indicative of increased steam emission in the Crater.
No views of the dome were possible during the early part of today because of the low cloud cover on the volcano.
Dome growth is continuing and therefore the threats posed by the Soufriere Hills Volcano continue at the same or a greater level as over the past several months. The Tar River and Long Ground areas to the east and the upper Fort Ghaut, Gages Village and Upper Amersham areas to the west are still extremely hazardous. People should not enter these areas under any circumstances because they put themselves and others at direct risk of very serious injury or death. People are urged to keep visits to the evacuated zone to a minimum.
