The level of activity at the volcano overnight has been very low, with only a few earthquakes and some rockfall signals recorded.
A very small number of hybrid and volcano-tectonic events were recorded during the night, but the main activity consisted of a few small to moderate rockfall signals. A small ash cloud which drifted west over Plymouth was produced by one of these rockfalls at 6.28 am.
Low cloud on the summit of the volcano has prevented any clear views of the dome this morning.
The volcano remains active and potentially dangerous. The lava dome is currently larger than ever before, with a steep eastern face, so 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 extremely important to wear an ash mask when there is ash in the air.
