Activity at the Soufriere Hills volcano during this reporting period has continued at a relatively elevated level compared with early in the week. Over forty-four volcano-tectonic earthquakes occurred overnight, accompanied by a similar number of small hybrid events. The VT earthquakes continue to have many similar characteristics and are probably due to magma movement within the volcano. Variable amounts of low-amplitude broadband tremor has been recorded on the Gages seismometer during the night; at times the tremor has been near-continuous.
Low cloud cover over the summit of the volcano has prevented any clear views during the early morning.
MVO scientists expect that rockfalls and possibly pyroclastic flows will occur during the next few days as the unstable sides of the new scar feature at English's Crater stabilise. All indications are that the rockfalls and pyroclastic flows will be confined to the Tar River valley area. Dust masks should be worn at all times in ashy environments, which may persist for some time as ash dries out and blows around. Drivers should exercise caution and consideration for other road users, especially when driving through areas still affected by ash or gravel.
Individuals put themselves in extreme danger if they venture beyond the Long Ground area into the Tar River valley. All individuals passing checkpoints in whatever part of the island are reminded that they are entering areas which may become unsafe very quickly, and everyone should be on maximum alert in all of these areas. All residents of southern Montserrat are asked to once again ensure that they are familiar with evacuation procedures.
