Daily Report
Report for the period 16:00 1 July
to 16:00 2 July 1996

Activity at the Soufriere Hills Volcano has been at about the same relatively low level as during the previous twenty-four hours. Small and moderate-sized rockfalls from the lava dome were the dominant events.

Rockfall and hybrid earthquake activities were at marginally higher levels than yesterday. Sixty four rockfalls and eighteen hybrid earthquakes were recorded by the seismic network. The largest rockfalls occurred at 19:07 on 1 July and at 01:43 and 11:04 today. There were no reports of ash clouds or ashfall from any of these events. Long period earthquakes remained low, with only one recorded over the reporting period. A small volcano-tectonic earthquake was also recorded. It was located at shallow depth under the volcano. Low-amplitude broadband tremor continued from the previous reporting period until 8:30 pm yesterday. After that time it occurred intermittently at lower intensity.

Visibility was poor for much of the day, with the summit obscured by clouds. Due to the poor visibility no EDM measurements were taken today. The results of yesterdays surveys at Amersham/ Dagenham/Chances steps lines showed no change over a two days. No COSPEC measurements were taken.

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 an absolute minimum. 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. 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.
