Morning Update
Report for the period 16:00 01 September
to 07:00 02 September 1996

The level of activity at the Soufriere Hills volcano during the night was about the same as that observed during the previous reporting period. The nature of the activity is still one characterised by small- to moderate-sized rockfalls mainly from the eastern flank of the growing lava dome. Intermittent low-amplitude broadband tremor was also recorded at most of the stations closest to the Crater throughout the update period.

Low cloud cover on the volcano during the early morning period prevented any views of the dome.

Further rockfalls and pyroclastic flows will occur but all indications at the moment are that the pyroclastic flows will be confined to the Tar River Valley area. However, areas affected by associated ashfalls will obviously depend on the direction and strength of the wind at the time. Extreme care should be taken when driving in areas affected by ashfalls. Dust masks should be worn in ashy environments.

The Tar River Valley and surrounding areas are extremely hazardous and should not be entered under any circumstances.
