In Conjunction With The MVO.

The current alert level is AMBER

Once again rockfall signals and small pyroclastic flows have dominated activity at the Soufriere Hills Volcano in Montserrat during the last 24 hours. Overall there were over 100 rockfall signals in the reporting period plus some long period, hybrid and volcano-tectonic earthquakes.

Overnight and early this morning there were two regional tectonic earthquakes recorded, these were about 100 kilometres from Montserrat.

Yesterday and this morning (Weds) low cloud cover has hidden the dome from view however it appears as if the area of active growth is still on the southern part of the dome. Material is still being shed over both the southeast and southwest of the dome into the Tar River Valley and the White River Valley.

Heavy rain overnight caused some flash flood signals to be recorded on the Gages seismometer in the vicinity of Fort Ghaut.

This afternoon there will be the usual testing of the automated alarm system.

The alert level remains at AMBER and scientists warn that the Tar River and White River Valleys are both very dangerous and no one should visit these areas for any reason what-so-ever.
