The level of activity at the volcano overnight has been higher than over the last week. A swarm of volcano-tectonic and hybrid earthquakes started at approximately 7.30 pm last night and is continuing at the time of reporting. The intensity of the swarm peaked at about 2.00 am this morning. A signal generally associated with flash-flooding was recorded on Gages seismic station at approximately 3.50 am. In addition, a few small to medium rockfall signals were also recorded by the seismic network during this period.
Overnight rain has caused heavy cloud to form over the volcano and therefore no good views have been obtained this morning.
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. 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.
