Morning Update
0700H 11 June, 1996


No marked change in the level of activity at the Soufriere Hill Volcano could be inferred from the overnight seismic records. Small- to moderate-size rockfall continued to occur on the dome and these signals were recorded on seismic stations closest to the volcano. Several long-period and a few hybrid earthquakes were also recorded.

Low-amplitude broadband tremor, generally an indication of the level of steam and other gaseous emissions, occurred intermittently for most of the night.

Low cloud during the late afternoon and early morning prevented views of all but the lower flanks of the volcano. The MVO staff believe that the focus of dome growth remains in the area behind the Gages section of the crater rim. When viewed yesterday morning this area was filled to the rim and a few large blocks had already spilled over into Fort Ghaut. The danger levels on the upper western side of the volcano is now heightened. Visits to the evacuated zone should be kept to a minimum. Under no circumstances should the Tar River, Long Ground Whites and upper Gages Valley should be visited. People who fail to comply with these warnings will put themselves at direct risk of serious injury or horrible death.
