The volcano is potentially very dangerous. The level of activity could increase at any time and everyone should remain vigilant and listen to Radio Montserrat. The threat of pyroclastic flows means that the Tar River and Long Ground areas are extremely dangerous. So is the St. Patrick's area which is threatened by the instability of the Galways Wall. People must not enter these areas.
The swarm of VT earthquakes that started on the evening of 25 November continued overnight. 29 VT earthquakes were recorded overnight, at rates up to five per hour. They were located at shallow depths beneath the crater, similar to almost all the swarm activity seen since late October. Rockfall activity was low overnight, with only three signals recorded. The Gages station has recorded continuous tremor throughout the night, although the level of this has gradually declined since 5 a.m. this morning.
The summit of the volcano was cloudy this morning and no good views of the dome have been possible.
