Daily Report
Report for the period 16:00 12 July
to 16:00 13 July 1996

Activity at the Soufriere Hills Volcano during this reporting period was at about the same relatively low level as during the previous twenty four hours. It continues to be dominated mainly by small- to moderate-sized rockfalls from the southern and southeastern flanks of the growing lava dome.

Fourteen (14) rockfall, 22 hybrid and 9 long-period events were recorded. Low- to moderate-amplitude broadband tremor of duration ranging from several minutes to a few hours occurred intermittently throughout the period.

Visibility was generally poor, with the volcano being obscured by clouds.

GPS and gravity measurements were made today in the western part of the volcano but the data is still being processed.

COSPEC and EDM measurements were not made because of poor weather .

The Soufriere Hills Volcano is still considered to be highly dangerous to people and property on it's eastern and upper western flanks. Visits to the evacuated zone must be kept to a minimum. The Tar River and Long Ground areas to the east and upper Fort Ghaut, Gages Village and Upper Amersham areas to the west are all extremely dangerous. All access roads to these areas remain closed and people should not enter these areas under any circumstances. If they do, they put themselves and others at direct risk of serious injury or death.
