Seismic activity at the volcano overnight has been quiet for most of the reporting period. The earthquake swarm that began yesterday morning ended at about 11.00 pm last night although there have been several small hybrid events since that time. Several of the larger earthquakes probably triggered pyroclastic flows over Galway's Wall since they were followed by prolonged signals. Since the end of the earthquake swarm there have been several small to moderate rockfall signals recorded by the seismic network.
Low cloud on the top of the volcano is currently hampering views of the dome and crater.
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 and shows signs of becoming more active. 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. 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.
