The volcano has been quiet overnight. There was a swarm of volcano-tectonic earthquakes between 9.01 pm and approximately 1.00am. This was followed by a few small to medium rockfall signals, but no tremor was recorded and no significant ash cloud could be seen.
The visibility is reasonably good, and views of the dome may be possible later in the day.
The current activity has reached a plateau, which gives the scientists confidence that there will be no life-threatening activity in the near future. However, the volcano is still potentially dangerous, and the activity could escalate at any time. The eastern face of the dome is steep, and further pyroclastic flows are likely. 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 very important to wear an ash mask when there is ash in the air.
