Overnight, the level of activity at the volcano has been very low. Two small hybrid earthquakes were recorded by the seismic network, but otherwise the activity was dominated by small rockfall signals which have occurred intermittently throughout the reporting period. Three larger rockfall signals were recorded at approximately 5 am. Low amplitude tremor on the Gages seismic station died away at about 7 pm last night. The seismicity indicates that the dome continues to grow.
Low cloud on the top of the volcano is currently hampering views of the dome and crater, although the cloud is clearing and good views may be possible later in the day.
The scientific team at the Montserrat Volcano Observatory would like to re-iterate the following points. The volcano remains active and potentially dangerous. The lava dome is currently larger than ever before. There are several areas on the eastern and south-eastern face which appear very unstable and further pyroclastic flows are likely. It also seems likely that there will be further pyroclastic flows from the dome above Galway's Wall, especially if an earthquake swarm occurs. Explosive activity similar to the September 17 event and possibly larger is still a distinct possibility. People entering zone C must remain alert, listen to Radio Montserrat and be ready to leave at short notice. Only essential visits should be made. The ash levels in Plymouth are hazardous, and it is extremely important to wear an ash mask when there is ash in the air.
