Morning Update
Report for the period 16:00 30 August
to 07:00 31 August 1996

The level of activity at the Soufriere Hills volcano during the night was slightly lower than that observed during the previous reporting period but the pattern was still dominated by small- to moderate-sized rockfalls from the flanks of the lava dome. Rockfall activity was especially persistent during the period 22:00 on 30 August to 02:00 this morning. Intermittent low-amplitude broadband tremor was also recorded at most of the stations closest to the Crater throughout the update period.

The cloud cover on the volcano was very low during the early morning period.

Extreme care should be exercised when driving in areas affected by recent ashfalls. Please do not forget to wear dust masks. 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.

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