Seismic activity has remained at a relatively high level overnight, with continuation of the bands of seismic tremor. The bands are now about 8 hours apart, and the energy in the bands has not changed overnight. Some hybrid events and rockfall signals continue to be recorded - almost all the rockfalls are thought to be coming from the active area on top of the October 1 dome.
The summit is obscured by cloud this morning, and no observations have been possible.
The most immediate dangers from the volcano remain in the Tar River valley and surrounding areas, where pyroclastic flows are likely to be generated at any time. Overtopping of the Farrell's Wall would rapidly endanger the area to the north of the crater, including the central corridor route. Rapid dome growth has in the past led to large dome collapses, generation of pyroclastic flows and ash clouds and on one occasion to an explosive event. None of the above phenomena can be ruled out for the current phase of activity over the next few days to weeks, especially if the rate of dome growth continues to be very high.
MVO would like to wish everyone on Montserrat, and all Montserratians overseas, a happy and peaceful New Year.
