During the past twelve hours, activity have been lower than the previous 24-hour update period. Small to moderate sized rockfalls from the dome continued to be the main events. The largest event occurred at 01:57 am on June 30. It lasted just over ninety seconds and saturated only the Long Ground seismic record. All other rockfall signals were much smaller in amplitude and duration. The occurrence of long period and hybrid earthquakes were at a low level throughout the update period. Venting also appeared to have been at a very low level.
Visibility remained very poor during the daylight hours of the update period. Only views of the lower flanks of the volcano have been possible.
Despite this extended period of low activity, the volcano remains unstable and therefore continues to be hazardous to people and property on both the eastern and upper western flanks. 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 still extremely hazardous. The road between Lee's Estate and Ryner's Village remains closed. People should not enter these areas under any circumstances. If they do, they put themselves and others at direct risk of very serious injury or death. Visits to the rest of the evacuated zone should be kept to an absolute minimum.
